Guiding Principles +## 1. Guiding Principles Our primary goal is to build a robust, maintainable, scalable, and secure CCProxy API Server. These conventions are rooted in the following principles: - * **Clarity over Cleverness:** Code should be easy to read and understand, even by someone new to the project. - * **Explicit over Implicit:** Be clear about intentions and dependencies. - * **Consistency:** Follow established patterns within the project. - * **Single Responsibility Principle (SRP):** Each module, class, or function should have one clear purpose. - * **Loose Coupling, High Cohesion:** Modules should be independent but related components within a module should be grouped. - * **Testability:** Write code that is inherently easy to unit and integrate test. - * **Pythonic:** Embrace PEP 8 and the Zen of Python (`import this`). - -## 2\. General Python Conventions - - * **PEP 8 Compliance:** Adhere strictly to PEP 8 – The Style Guide for Python Code. - * Use `Black` for auto-formatting to ensure consistent style. - * Line length limit is **88 characters** (Black's default). - * **Python Version:** Target **Python 3.10+**. Utilize features like union types (`X | Y`) where applicable. - * **No Mutable Default Arguments:** Avoid using mutable objects (lists, dicts, sets) as default arguments in function definitions. - * **Bad:** `def foo(items=[])` - * **Good:** `def foo(items: Optional[List] = None): if items is None: items = []` - -## 3\. Naming Conventions - -Consistency in naming is crucial for navigability within our domain-driven structure. - - * **Packages/Directories:** `snake_case` (e.g., `api_server`, `claude_sdk`, `auth/oauth`). - * **Modules (.py files):** `snake_case` (e.g., `manager.py`, `client.py`, `interfaces.py`). - * **Classes:** `CamelCase` (e.g., `ProxyService`, `OpenAIAdapter`, `CredentialsManager`). - * **Abstract Base Classes (ABCs) / Protocols:** Suffix with `ABC` or `Protocol` respectively (e.g., `HTTPClientABC`, `RequestTransformerProtocol`). - * **Pydantic Models:** `CamelCase` (e.g., `MessageCreateParams`, `OpenAIChatCompletionRequest`). - * **Functions, Methods, Variables:** `snake_case` (e.g., `handle_request`, `get_access_token`, `max_tokens`). - * **Constants (Global):** `UPPER_SNAKE_CASE` (e.g., `DEFAULT_PORT`, `API_VERSION`). - * **Private/Internal Members:** - * **`_single_leading_underscore`:** For internal use within a module or class. Do not import or access these directly from outside their defined scope. - * **`__double_leading_underscore` (Name Mangling):** Reserve this for preventing name clashes in inheritance hierarchies, rarely used. - -## 4\. Imports - -Imports should be clean, organized, and explicit. - - * **Ordering:** Use `isort` for consistent import ordering. General order: - 1. Standard library imports. - 2. Third-party library imports. - 3. First-party (`ccproxy` project) imports. - 4. Relative imports. - * **Absolute Imports Preferred:** Use absolute imports for modules within the `ccproxy` project whenever possible, especially when crossing domain boundaries. - * **Good:** `from ccproxy.auth.manager import AuthManager` - * **Avoid (if not within the same sub-domain):** `from ..auth.manager import AuthManager` - * **Relative Imports for Siblings:** Use relative imports for modules within the same logical sub-package/directory. - * **Good (inside `adapters/openai/`):** `from .models import OpenAIModel` - * **`__all__` in `__init__.py`:** Each package's `__init__.py` file **must** define an `__all__` list to explicitly expose its public API. This controls what `from package import *` imports and guides explicit imports. - * **Example (`ccproxy/auth/__init__.py`):** - ```python - from .manager import AuthManager - from .models import Credentials - from .storage.base import TokenStorage - - __all__ = ["AuthManager", "Credentials", "TokenStorage"] - ``` - * **Minimize Imports:** Only import what you need. Avoid `from module import *`. - -## 5\. Typing - -Type hints are mandatory for clarity, maintainability, and static analysis. - - * **All Function Signatures:** All function parameters and return values must be type-hinted. - * **Class Attributes:** Use type hints for class attributes, especially Pydantic models. - * **`from __future__ import annotations`:** Use this at the top of every module to enable postponed evaluation of type annotations, especially useful for forward references and preventing circular import issues. - * **`Optional` Types:** Use `Type | None` for optional values (Python 3.10+) or `Optional[Type]` (from `typing`) for older versions/clarity. - * **`Annotated` (Pydantic v2):** Use `Annotated` for `Field` and other Pydantic-specific metadata. - * **Example:** `model: Annotated[str, Field(description="Model ID")]` - * **Generics and Protocols:** Use `TypeVar`, `Generic`, `Protocol` (from `typing`) in `core/interfaces.py` and other modules where abstract types are defined. - * **Type Aliases:** Use `TypeAlias` (from `typing`) for complex type hints in `core/types.py` or domain-specific `models.py` files to improve readability. - -## 6\. Docstrings and Comments - -Code should be self-documenting first, then supplemented by comments and docstrings. - - * **Docstrings:** - * Every **public module, class, method, and function** must have a docstring. - * Use **Google Style Docstrings** or **Sphinx Style** consistently throughout the project. - * Describe the purpose, arguments, return values, and any exceptions raised. - * **Comments:** - * Explain *why* a particular piece of code exists or was chosen, not *what* it does (which should be clear from the code itself). - * Avoid redundant comments that simply re-state the code. - * Use comments for complex algorithms, workarounds, or non-obvious logic. - * **TODO/FIXME/HACK:** Use these markers consistently for areas needing attention. Explain briefly what needs to be done. - * `# TODO: Implement rate limiting here.` - * `# FIXME: This logic has a known race condition under high load.` - * `# HACK: Temporary workaround for issue #123.` - -## 7\. Error Handling - -Define clear error boundaries and handle exceptions gracefully. - - * **Custom Exceptions:** - * All custom exceptions **must** inherit from `core.errors.ClaudeProxyError` or its more specific sub-classes defined in `core/errors.py`. - * Domain-specific exceptions should be defined within their respective domain's `exceptions.py` module (e.g., `auth/exceptions.py`, `docker/exceptions.py`). - * **Catch Specific Exceptions:** Always catch specific exception types, not bare `except Exception:`. - * **Propagate with Context:** When re-raising or wrapping exceptions, include the original exception as the cause using `raise NewError(...) from OriginalError`. - * **FastAPI `HTTPException`:** In API routes, raise `fastapi.HTTPException` with appropriate `status_code` and `detail` (which should be a dictionary conforming to our API error models). Internal services should raise custom exceptions, and the `api/middleware/errors.py` should convert them to `HTTPException`. - -## 8\. Asynchronous Programming - -Adhere to modern `asyncio` patterns. - - * **`async` / `await`:** Use `async def` and `await` consistently for all asynchronous operations (I/O-bound tasks). - * **Asynchronous Libraries:** Prefer `httpx` for HTTP requests, `anyio` for high-level async primitives, and `asyncio` for low-level tasks. - * **Concurrency:** Use `asyncio.gather` for parallel independent tasks. Be mindful of CPU-bound tasks in `async` functions (offload to `ThreadPoolExecutor` if necessary). - -## 9\. Testing - -Tests are integral to the development process. - -* **Framework:** Use `pytest`. -* **Structure:** All tests live in `tests/` directory with descriptive filenames - - `test_api_*.py` - API endpoint tests - - `test_auth.py` - Authentication tests - - `test_*.py` - Other component tests -* **Fixtures:** Use `conftest.py` for shared fixtures -* **Mocking:** Use `unittest.mock` for external dependencies -* **Naming:** Test files: `test_feature.py`. Test functions: `test_specific_behavior()` -* **Coverage:** Aim for high coverage on critical paths (auth, API endpoints) - -## 10\. Dependency Management - - * **`pyproject.toml`:** Use `pyproject.toml` (e.g., with Poetry, PDM, or Rye) for project metadata and primary dependency management. This is the source of truth for dependencies. - * **`requirements.txt` / `requirements-dev.txt`:** Generate these from `pyproject.toml` for deployment and development environments respectively. - * **Pin Dependencies:** Pin exact versions of production dependencies to ensure reproducible builds. - -## 11\. Configuration - - * **Centralized Settings:** All configurable parameters must be defined in Pydantic `BaseSettings` models within `config/settings.py`. - * **Precedence:** Environment variables should override `.env` file settings, which override config file settings, which override default values. This should be handled by `config/loader.py`. - * **Type-Safe:** Leverage Pydantic's type validation for configuration values. - -## 12\. Security Considerations - - * **Input Validation:** All API inputs **must** be validated using Pydantic models. - * **Sensitive Data:** Never log raw API keys, tokens, or other sensitive user data. Mask or redact. - * **Authentication:** Enforce authentication using `api/middleware/auth.py` and `auth/dependencies.py` where required. - * **CORS:** Properly configure CORS origins in `api/middleware/cors.py` to only allow trusted clients. - * **Least Privilege:** When running Docker containers, use `docker/adapter.py` and `docker/builder.py` to configure the least necessary privileges (e.g., specific UID/GID mapping, limited volumes). - * **Dependency Scanning:** Regularly scan dependencies for known vulnerabilities. - -## 13\. Tooling** - - -The `ccproxy` project leverages a modern, streamlined Python development toolchain to ensure high code quality, consistency, and efficient workflows. Our core tools are `uv` for package management and `ruff` for all code formatting, linting, and import sorting. - -These tools are enforced via `pre-commit` hooks for local development and validated in GitHub Actions CI pipelines. - -## **13.1. Core Tooling Stack** - -* **Package Management & Dependency Resolution:** `uv` - * Replaces traditional `pip` and dependency resolvers. - * Handles installing, syncing, and publishing packages. - * **Usage:** Orchestrated exclusively via the `Makefile` targets. Developers should **not** invoke `uv` directly. -* **Code Formatting:** `ruff format` - * Ensures consistent code style across the entire codebase. - * **Configuration:** Handled automatically by `ruff`'s default sensible settings, and `pyproject.toml` for project-specific overrides if needed (e.g., line length, though we use `Black`'s standard 88). - * **Enforcement:** - * **Local:** `pre-commit` hook (`ruff-format` hook). - * **CI:** Part of the `make ci` and `make check` targets. -* **Linting:** `ruff check` - * Identifies potential bugs, stylistic errors, and enforces best practices. - * **Configuration:** Configured via `pyproject.toml`. - * **Enforcement:** - * **Local:** `pre-commit` hook (`ruff` hook with `--fix` arg). - * **CI:** Part of the `make ci` and `make check` targets. -* **Import Sorting:** `ruff check --select I` (integrated into `ruff lint-fix`) - * Automatically organizes import statements according to PEP 8. - * **Configuration:** Handled by `ruff`'s import sorting capabilities. - * **Enforcement:** - * **Local:** `pre-commit` hook (`ruff` hook with `--fix` arg, or `make lint-fix`). - * **CI:** Part of the `make ci` and `make check` targets. -* **Static Type Checking:** `MyPy` - * Ensures type correctness and catches type-related errors early. - * **Configuration:** Configured via `pyproject.toml` (refer to `[tool.mypy]` section). Specific `additional_dependencies` are listed in `.pre-commit-config.yaml` for MyPy's virtual environment. - * **Enforcement:** - * **Local:** `pre-commit` hook (`mypy` hook). - * **CI:** Part of the `make ci` and `make check` targets. +* **Clarity over Cleverness:** Code should be easy to read and understand +* **Explicit over Implicit:** Be clear about intentions and dependencies +* **Consistency:** Follow established patterns within the project +* **Single Responsibility Principle:** Each module, class, or function should have one clear purpose +* **Loose Coupling, High Cohesion:** Modules should be independent but related components within a module should be grouped +* **Testability:** Write code that is inherently easy to unit and integration test +* **Pythonic:** Embrace PEP 8 and the Zen of Python (`import this`) + +## 2.

Plugin Architecture + +### Plugin Structure +Each plugin must follow the delegation pattern: + +```python +plugins/ +├── plugin_name/ +│ ├── __init__.py +│ ├── adapter.py # Main plugin interface +│ ├── plugin.py # Plugin declaration +│ ├── transformers/ # Request/response transformation +│ │ ├── request.py +│ │ └── response.py +│ ├── detection_service.py # Provider capability detection +│ ├── format_adapter.py # Protocol conversion (if needed) +│ └── auth/ # Authentication (if needed) +│ └── manager.py +``` + +### Delegation Pattern +Adapters integrate via explicit dependencies (HTTP client, auth manager, transformers) and the application request lifecycle: + +```python +class ProviderAdapter(BaseAdapter): + async def handle_request(self, request, endpoint, method): + # resolve endpoint/handler config, then execute with injected services + target_url, needs_conversion = await self._resolve_endpoint(endpoint) + cfg = await self._create_handler_config(needs_conversion) + return await self._execute_request( + method=method, + target_url=target_url, + body=await request.body(), + auth_headers={}, + access_token=None, + request_headers=dict(request.headers), + handler_config=cfg, + endpoint=endpoint, + needs_conversion=needs_conversion, + request_context=RequestContext.get_current(), + ) +``` + +### Format Adapters +- Declarative only: plugins declare adapters in `PluginManifest.format_adapters` with an optional `priority` (lower wins). +- Registration: core pre-registers a few built-in adapters; plugin-declared adapters are registered from manifests during startup. +- Conflicts: resolved by priority during registry finalization; the winning adapter is selected automatically. +- Manual setup: runtime `_setup_format_registry()` is a no-op; avoid calling `registry.register()` from plugins (tests may do so explicitly). +- No global flags: feature flags for adapter selection were removed; manifest-based behavior is always enabled. + +## 7.

Mix and match auth modes as needed -8. **NEW: Parametrized testing** - Test multiple scenarios in one test function +1. **Clean boundaries** - Unit tests mock at service boundaries only +2. **Fast execution** - Unit tests run in milliseconds, no timing dependencies +3. **Type safety** - All fixtures properly typed, mypy compliant +4. **Real components** - Test actual internal behavior, not mocked responses +5. **Performance-optimized patterns** - Use session-scoped fixtures for expensive operations +6. **Modern async patterns** - `@pytest.mark.asyncio(loop_scope="session")` for integration tests +7. **No overengineering** - Removed 180+ tests, 3000+ lines of complexity + +### Performance Guidelines + +#### When to Use Session-Scoped Fixtures +- **Plugin integration tests** -

-## For LLMs/AI Assistants - -When writing tests for this project: - -### Required (Unchanged) - -1. **MUST include proper type hints** - All test functions need `-> None` return type -2. **MUST pass mypy and ruff checks** - Type safety and formatting are required -3. Keep tests simple and focused -4. Follow the naming convention: `test_what_when_expected()` -5. Import necessary types: `TestClient`, `HTTPXMock`, `Path`, etc. - -### Recommended (New) - -6. **Use factory pattern** - For complex scenarios: `fastapi_client_factory.create_client()` -7. **Use composable auth** - Auth modes: `auth_mode_bearer_token`, `auth_mode_none`, etc. -8. **Use clear mock naming** - `mock_internal_claude_sdk_service`, `mock_external_anthropic_api` -9. **Use parametrized testing** - Test multiple scenarios in one function -10. **Prefer convenience fixtures** - `client_bearer_auth`, `client_no_auth` for simple cases +1. **Start here**: Read this file and `tests/fixtures/integration.py` +2. **Run tests**: `make test` to ensure everything works (606 optimized tests) +3. **Choose pattern**: + - Session-scoped fixtures for plugin tests (`metrics_integration_client`) + - Factory patterns for dynamic configs (`integration_client_factory`) + - Unit tests for isolated components +4. **Performance first**: Use `ERROR` logging level, session-scoped apps for expensive operations +5. **Type safety**: All test functions need `-> None` return type, proper fixture typing +6. **Modern async**: Use `@pytest.mark.asyncio(loop_scope="session")` for integration tests +7. **Mock external only**: Don't mock internal components, test real behavior -### Legacy Support (Backward Compatibility) +## Migration from Old Architecture -- All existing fixtures still work: `client`, `client_with_auth`, `mock_claude_service` -- Use existing patterns in `tests/` as reference -- Only mock external HTTP calls using `pytest_httpx` -- Use fixtures from `conftest.py`, don't create new combinatorial ones +**All existing test patterns still work** - but new tests should use the performance-optimized patterns: -**Type Safety Checklist:** +### Current Recommended Patterns (2024) -- [ ] All test functions have `-> None` return type -- [ ] All parameters have type hints (especially fixtures) -- [ ] Complex variables have explicit type annotations -- [ ] Proper imports from `typing` module -- [ ] Code passes `make typecheck` and `make lint` +- **Session-scoped integration fixtures** - `metrics_integration_client`, `disabled_plugins_client` +- **Async factory patterns** - `integration_client_factory` for dynamic configs +- **Manual logging setup** - `setup_logging(json_logs=False, log_level_name="ERROR")` +- **Session loop scope** - `@pytest.mark.asyncio(loop_scope="session")` for integration tests +- **Service container pattern** - `create_service_container()` + `create_app()` +- **Plugin lifecycle management** - `initialize_plugins_startup()` in fixtures -**Factory Pattern Checklist:** +### Performance Optimizations Applied -- [ ] Use `fastapi_client_factory` for complex test scenarios -- [ ] Use auth modes (`auth_mode_bearer_token`) instead of manual auth setup -- [ ] Use clear service mock names (`mock_internal_claude_sdk_service`) -- [ ] Consider parametrized testing for multiple scenarios -- [ ] Use convenience fixtures (`client_bearer_auth`) for simple cases +- **Minimal logging** - ERROR level only, no JSON logging, plugin logging disabled +- **Session-scoped apps** - Expensive plugin initialization done once per session +- **Streamlined fixtures** - 515 lines (was 1117), focused on essential patterns +- **Real component testing** - Mock external APIs only, test actual internal behavior -Remember: **Simple tests that actually test real behavior > Complex tests with lots of mocks.** +Plugin tests are now centralized under `tests/plugins//{unit,integration}` instead of co-located in `plugins//tests`. Update any paths and imports accordingly. -**Migration is optional** - all existing tests continue working. Use new patterns for better maintainability and testing capabilities. +The architecture has been significantly optimized for performance while maintaining full functionality. diff --git a/ccproxy/__init__.py b/ccproxy/__init__.py deleted file mode 100644 index 83d4cab5..00000000 --- a/ccproxy/__init__.py +++ /dev/null @@ -1,4 +0,0 @@ -from ._version import __version__ -

Here are some examples to demonstrate appropriate verbosity:\n\nuser: 2 + 2\nassistant: 4\n\n\n\nuser: what is 2+2?\nassistant: 4\n\n\n\nuser: is 11 a prime number?\nassistant: Yes\n\n\n\nuser: what command should I run to list files in the current directory?\nassistant: ls\n\n\n\nuser: what command should I run to watch files in the current directory?\nassistant: [runs ls to list the files in the current directory, then read docs/commands in the relevant file to find out how to watch files]\nnpm run dev\n\n\n\nuser: How many golf balls fit inside a jetta?\nassistant: 150000\n\n\n\nuser: what files are in the directory src/?\nassistant: [runs ls and sees foo.c, bar.c, baz.c]\nuser: which file contains the implementation of foo?\nassistant: src/foo.c\n\nWhen you run a non-trivial bash command, you should explain what the command does and why you are running it, to make sure the user understands what you are doing (this is especially important when you are running a command that will make changes to the user's system).\nRemember that your output will be displayed on a command line interface. Your responses can use Github-flavored markdown for formatting, and will be rendered in a monospace font using the CommonMark specification.\nOutput text to communicate with the user; all text you output outside of tool use is displayed to the user. Only use tools to complete tasks. Never use tools like Bash or code comments as means to communicate with the user during the session.\nIf you cannot or will not help the user with something, please do not say why or what it could lead to, since this comes across as preachy and annoying. Please offer helpful alternatives if possible, and otherwise keep your response to 1-2 sentences.\nOnly use emojis if the user explicitly requests it. Avoid using emojis in all communication unless asked.\nIMPORTANT: Keep your responses short, since they will be displayed on a command line interface.\n\n# Proactiveness\nYou are allowed to be proactive, but only when the user asks you to do something. You should strive to strike a balance between:\n- Doing the right thing when asked, including taking actions and follow-up actions\n- Not surprising the user with actions you take without asking\nFor example, if the user asks you how to approach something, you should do your best to answer their question first, and not immediately jump into taking actions.\n\n# Following conventions\nWhen making changes to files, first understand the file's code conventions. Mimic code style, use existing libraries and utilities, and follow existing patterns.\n- NEVER assume that a given library is available, even if it is well known. Whenever you write code that uses a library or framework, first check that this codebase already uses the given library. For example, you might look at neighboring files, or check the package.json (or cargo.toml, and so on depending on the language).\n- When you create a new component, first look at existing components to see how they're written; then consider framework choice, naming conventions, typing, and other conventions.\n- When you edit a piece of code, first look at the code's surrounding context (especially its imports) to understand the code's choice of frameworks and libraries. Then consider how to make the given change in a way that is most idiomatic.\n- Always follow security best practices. Never introduce code that exposes or logs secrets and keys. Never commit secrets or keys to the repository.\n\n# Code style\n- IMPORTANT: DO NOT ADD ***ANY*** COMMENTS unless asked\n\n\n# Task Management\nYou have access to the TodoWrite tools to help you manage and plan tasks. Use these tools VERY frequently to ensure that you are tracking your tasks and giving the user visibility into your progress.\nThese tools are also EXTREMELY helpful for planning tasks, and for breaking down larger complex tasks into smaller steps. If you do not use this tool when planning, you may forget to do important tasks - and that is unacceptable.\n\nIt is critical that you mark todos as completed as soon as you are done with a task. Do not batch up multiple tasks before marking them as completed.\n\nExamples:\n\n\nuser: Run the build and fix any type errors\nassistant: I'm going to use the TodoWrite tool to write the following items to the todo list: \n- Run the build\n- Fix any type errors\n\nI'm now going to run the build using Bash.\n\nLooks like I found 10 type errors. I'm going to use the TodoWrite tool to write 10 items to the todo list.\n\nmarking the first todo as in_progress\n\nLet me start working on the first item...\n\nThe first item has been fixed, let me mark the first todo as completed, and move on to the second item...\n..\n..\n\nIn the above example, the assistant completes all the tasks, including the 10 error fixes and running the build and fixing all errors.\n\n\nuser: Help me write a new feature that allows users to track their usage metrics and export them to various formats\n\nassistant: I'll help you implement a usage metrics tracking and export feature. Let me first use the TodoWrite tool to plan this task.\nAdding the following todos to the todo list:\n1. Research existing metrics tracking in the codebase\n2. Design the metrics collection system\n3. Implement core metrics tracking functionality\n4. Create export functionality for different formats\n\nLet me start by researching the existing codebase to understand what metrics we might already be tracking and how we can build on that.\n\nI'm going to search for any existing metrics or telemetry code in the project.\n\nI've found some existing telemetry code. Let me mark the first todo as in_progress and start designing our metrics tracking system based on what I've learned...\n\n[Assistant continues implementing the feature step by step, marking todos as in_progress and completed as they go]\n\n\n\nUsers may configure 'hooks', shell commands that execute in response to events like tool calls, in settings. Treat feedback from hooks, including , as coming from the user. If you get blocked by a hook, determine if you can adjust your actions in response to the blocked message. If not, ask the user to check their hooks configuration.\n\n# Doing tasks\nThe user will primarily request you perform software engineering tasks. This includes solving bugs, adding new functionality, refactoring code, explaining code, and more. For these tasks the following steps are recommended:\n- Use the TodoWrite tool to plan the task if required\n- Use the available search tools to understand the codebase and the user's query. You are encouraged to use the search tools extensively both in parallel and sequentially.\n- Implement the solution using all tools available to you\n- Verify the solution if possible with tests. NEVER assume specific test framework or test script. Check the README or search codebase to determine the testing approach.\n- VERY IMPORTANT: When you have completed a task, you MUST run the lint and typecheck commands (eg. npm run lint, npm run typecheck, ruff, etc.) with Bash if they were provided to you to ensure your code is correct. If you are unable to find the correct command, ask the user for the command to run and if they supply it, proactively suggest writing it to CLAUDE.md so that you will know to run it next time.\nNEVER commit changes unless the user explicitly asks you to. It is VERY IMPORTANT to only commit when explicitly asked, otherwise the user will feel that you are being too proactive.\n\n- Tool results and user messages may include tags. tags contain useful information and reminders. They are NOT part of the user's provided input or the tool result.\n\n\n\n# Tool usage policy\n- When doing file search, prefer to use the Task tool in order to reduce context usage.\n- You should proactively use the Task tool with specialized agents when the task at hand matches the agent's description.\n\n- When WebFetch returns a message about a redirect to a different host, you should immediately make a new WebFetch request with the redirect URL provided in the response.\n- You have the capability to call multiple tools in a single response. When multiple independent pieces of information are requested, batch your tool calls together for optimal performance. When making multiple bash tool calls, you MUST send a single message with multiple tools calls to run the calls in parallel. For example, if you need to run \"git status\" and \"git diff\", send a single message with two tool calls to run the calls in parallel.\n\n\nYou can use the following tools without requiring user approval: Bash(rm:*), Bash(rg:*), Bash(uv run:*), mcp__serena__initial_instructions, mcp__serena__list_memories, mcp__serena__list_dir, mcp__serena__get_symbols_overview, mcp__serena__find_symbol, mcp__serena__search_for_pattern, Bash(make:*), mcp__serena__read_memory, mcp__serena__replace_regex, mcp__serena__think_about_whether_you_are_done, Bash(chmod:*), Bash(ruff check:*), mcp__serena__summarize_changes, Bash(chmod:*), mcp__serena__find_referencing_symbols, mcp__serena__replace_symbol_body, Bash(mv:*), Bash(ls:*), mcp__serena__insert_after_symbol, mcp__serena__think_about_collected_information, mcp__serena__check_onboarding_performed, mcp__serena__find_file, Bash(mkdir:*), Bash(python:*), mcp__serena__think_about_task_adherence, Bash(find:*), Bash(python -m pytest tests/test_credentials_refactored.py::TestJsonFileStorage::test_atomic_file_write -xvs), Bash(python -m pytest tests/test_credentials_refactored.py::TestJsonFileStorage::test_save_and_load -xvs), Bash(find:*), Bash(grep:*), Bash(pytest:*), Bash(mypy:*), Bash(ruff format:*), Bash(ruff format:*), mcp__serena__activate_project, mcp__serena__get_current_config, mcp__serena__insert_before_symbol, Bash(touch:*), Bash(tree:*), Bash(tree:*), Bash(true), Bash(sed:*), Bash(timeout:*), Bash(git commit:*), mcp__serena__initial_instructions, mcp__serena__check_onboarding_performed, mcp__serena__list_dir, mcp__serena__think_about_whether_you_are_done, mcp__serena__read_memory, Bash(pytest:*), Bash(mypy:*), Bash(ruff check:*), Bash(ruff format:*), Bash(python:*), mcp__serena__summarize_changes, Bash(ls:*), mcp__serena__find_file, mcp__serena__replace_regex, mcp__serena__get_symbols_overview, mcp__serena__think_about_task_adherence, mcp__serena__insert_after_symbol, Bash(uv add:*), Bash(uv pip:*), Bash(uv add:*), Bash(uv run:*), Bash(find:*), Bash(curl:*), Bash(bunx:*), Bash(bun run:*), Bash(bun build:*), mcp__zen__challenge, Bash(docker logs:*), mcp__zen__codereview, mcp__zen__analyze, mcp__zen__thinkdeep, mcp__zen__chat, mcp__zen__consensus, mcp__exa__web_search_exa, Bash(git add:*), mcp__zen__planner, Bash(ccproxy serve:*), WebFetch(domain:raw.githubusercontent.com), mcp__context7__resolve-library-id, mcp__serena__onboarding, mcp__serena__write_memory, Bash(git tag:*), Bash(git rebase:*), Bash(git checkout:*)\n\n\n\nHere is useful information about the environment you are running in:\n\nWorking directory: /home/rick/projects-caddy/ccproxy-api\nIs directory a git repo: Yes\nPlatform: linux\nOS Version: Linux 6.12.36\nToday's date: 2025-08-13\n\nYou are powered by the model named Sonnet 4.

You have \naccess to semantic coding tools on which you rely heavily for all your work, as well as collection of memory \nfiles containing general information about the codebase. You operate in a resource-efficient and intelligent manner, always\nkeeping in mind to not read or generate content that is not needed for the task at hand.\n\nWhen reading code in order to answer a user question or task, you should try reading only the necessary code. \nSome tasks may require you to understand the architecture of large parts of the codebase, while for others,\nit may be enough to read a small set of symbols or a single file.\nGenerally, you should avoid reading entire files unless it is absolutely necessary, instead relying on\nintelligent step-by-step acquisition of information. However, if you already read a file, it does not make\nsense to further analyse it with the symbolic tools (except for the `find_referencing_symbols` tool), \nas you already have the information.\n\nI WILL BE SERIOUSLY UPSET IF YOU READ ENTIRE FILES WITHOUT NEED!\n\nCONSIDER INSTEAD USING THE OVERVIEW TOOL AND SYMBOLIC TOOLS TO READ ONLY THE NECESSARY CODE FIRST!\nI WILL BE EVEN MORE UPSET IF AFTER HAVING READ AN ENTIRE FILE YOU KEEP READING THE SAME CONTENT WITH THE SYMBOLIC TOOLS!\nTHE PURPOSE OF THE SYMBOLIC TOOLS IS TO HAVE TO READ LESS CODE, NOT READ THE SAME CONTENT MULTIPLE TIMES!\n\n\nYou can achieve the intelligent reading of code by using the symbolic tools for getting an overview of symbols and\nthe relations between them, and then only reading the bodies of symbols that are necessary to answer the question \nor complete the task. \nYou can use the standard tools like list_dir, find_file and search_for_pattern if you need to.\nWhen tools allow it, you pass the `relative_path` parameter to restrict the search to a specific file or directory.\nFor some tools, `relative_path` can only be a file path, so make sure to properly read the tool descriptions.\n\nIf you are unsure about a symbol's name or location (to the extent that substring_matching for the symbol name is not enough), you can use the `search_for_pattern` tool, which allows fast\nand flexible search for patterns in the codebase.This way you can first find candidates for symbols or files,\nand then proceed with the symbolic tools.\n\n\n\nSymbols are identified by their `name_path and `relative_path`, see the description of the `find_symbol` tool for more details\non how the `name_path` matches symbols.\nYou can get information about available symbols by using the `get_symbols_overview` tool for finding top-level symbols in a file,\nor by using `find_symbol` if you already know the symbol's name path. You generally try to read as little code as possible\nwhile still solving your task, meaning you only read the bodies when you need to, and after you have found the symbol you want to edit.\nFor example, if you are working with python code and already know that you need to read the body of the constructor of the class Foo, you can directly\nuse `find_symbol` with the name path `Foo/__init__` and `include_body=True`. If you don't know yet which methods in `Foo` you need to read or edit,\nyou can use `find_symbol` with the name path `Foo`, `include_body=False` and `depth=1` to get all (top-level) methods of `Foo` before proceeding\nto read the desired methods with `include_body=True`\nYou can understand relationships between symbols by using the `find_referencing_symbols` tool.\n\n\n\nYou generally have access to memories and it may be useful for you to read them, but also only if they help you\nto answer the question or complete the task. You can infer which memories are relevant to the current task by reading\nthe memory names and descriptions.\n\n\nThe context and modes of operation are described below. From them you can infer how to interact with your user\nand which tasks and kinds of interactions are expected of you.\n\nContext description:\nYou are running in IDE assistant context where file operations, basic (line-based) edits and reads, \nand shell commands are handled by your own, internal tools.\nThe initial instructions and the current config inform you on which tools are available to you,\nand how to use them.\nDon't attempt to use any excluded tools, instead rely on your own internal tools\nfor achieving the basic file or shell operations.\n\nIf serena's tools can be used for achieving your task, \nyou should prioritize them. In particular, it is important that you avoid reading entire source code files,\nunless it is strictly necessary! Instead, for exploring and reading code in a token-efficient manner, \nyou should use serena's overview and symbolic search tools. The call of the read_file tool on an entire source code \nfile should only happen in exceptional cases, usually you should first explore the file (by itself or as part of exploring\nthe directory containing it) using the symbol_overview tool, and then make targeted reads using find_symbol and other symbolic tools.\nFor non-code files or for reads where you don't know the symbol's name path you can use the patterns searching tool,\nusing the read_file as a last resort.\n\nModes descriptions:\n\n- You are operating in interactive mode. You should engage with the user throughout the task, asking for clarification\nwhenever anything is unclear, insufficiently specified, or ambiguous.\n\nBreak down complex tasks into smaller steps and explain your thinking at each stage. When you're uncertain about\na decision, present options to the user and ask for guidance rather than making assumptions.\n\nFocus on providing informative results for intermediate steps so the user can follow along with your progress and\nprovide feedback as needed.\n\n- You are operating in editing mode. You can edit files with the provided tools\nto implement the requested changes to the code base while adhering to the project's code style and patterns.\nUse symbolic editing tools whenever possible for precise code modifications.\nIf no editing task has yet been provided, wait for the user to provide one.\n\nWhen writing new code, think about where it belongs best. Don't generate new files if you don't plan on actually\nintegrating them into the codebase, instead use the editing tools to insert the code directly into the existing files in that case.\n\nYou have two main approaches for editing code - editing by regex and editing by symbol.\nThe symbol-based approach is appropriate if you need to adjust an entire symbol, e.g. a method, a class, a function, etc.\nBut it is not appropriate if you need to adjust just a few lines of code within a symbol, for that you should\nuse the regex-based approach that is described below.\n\nLet us first discuss the symbol-based approach.\nSymbols are identified by their name path and relative file path, see the description of the `find_symbol` tool for more details\non how the `name_path` matches symbols.\nYou can get information about available symbols by using the `get_symbols_overview` tool for finding top-level symbols in a file,\nor by using `find_symbol` if you already know the symbol's name path. You generally try to read as little code as possible\nwhile still solving your task, meaning you only read the bodies when you need to, and after you have found the symbol you want to edit.\nBefore calling symbolic reading tools, you should have a basic understanding of the repository structure that you can get from memories\nor by using the `list_dir` and `find_file` tools (or similar).\nFor example, if you are working with python code and already know that you need to read the body of the constructor of the class Foo, you can directly\nuse `find_symbol` with the name path `Foo/__init__` and `include_body=True`. If you don't know yet which methods in `Foo` you need to read or edit,\nyou can use `find_symbol` with the name path `Foo`, `include_body=False` and `depth=1` to get all (top-level) methods of `Foo` before proceeding\nto read the desired methods with `include_body=True`.\nIn particular, keep in mind the description of the `replace_symbol_body` tool. If you want to add some new code at the end of the file, you should\nuse the `insert_after_symbol` tool with the last top-level symbol in the file. If you want to add an import, often a good strategy is to use\n`insert_before_symbol` with the first top-level symbol in the file.\nYou can understand relationships between symbols by using the `find_referencing_symbols` tool. If not explicitly requested otherwise by a user,\nyou make sure that when you edit a symbol, it is either done in a backward-compatible way, or you find and adjust the references as needed.\nThe `find_referencing_symbols` tool will give you code snippets around the references, as well as symbolic information.\nYou will generally be able to use the info from the snippets and the regex-based approach to adjust the references as well.\nYou can assume that all symbol editing tools are reliable, so you don't need to verify the results if the tool returns without error.\n\n\nLet us discuss the regex-based approach.\nThe regex-based approach is your primary tool for editing code whenever replacing or deleting a whole symbol would be a more expensive operation.\nThis is the case if you need to adjust just a few lines of code within a method, or a chunk that is much smaller than a whole symbol.\nYou use other tools to find the relevant content and\nthen use your knowledge of the codebase to write the regex, if you haven't collected enough information of this content yet.\nYou are extremely good at regex, so you never need to check whether the replacement produced the correct result.\nIn particular, you know what to escape and what not to escape, and you know how to use wildcards.\nAlso, the regex tool never adds any indentation (contrary to the symbolic editing tools), so you have to take care to add the correct indentation\nwhen using it to insert code.\nMoreover, the replacement tool will fail if it can't perform the desired replacement, and this is all the feedback you need.\nYour overall goal for replacement operations is to use relatively short regexes, since I want you to minimize the number\nof output tokens. For replacements of larger chunks of code, this means you intelligently make use of wildcards for the middle part \nand of characteristic snippets for the before/after parts that uniquely identify the chunk.\n\nFor small replacements, up to a single line, you follow the following rules:\n\n 1. If the snippet to be replaced is likely to be unique within the file, you perform the replacement by directly using the escaped version of the \n original.\n 2. If the snippet is probably not unique, and you want to replace all occurrences, you use the `allow_multiple_occurrences` flag.\n 3. If the snippet is not unique, and you want to replace a specific occurrence, you make use of the code surrounding the snippet\n to extend the regex with content before/after such that the regex will have exactly one match.\n 4. You generally assume that a snippet is unique, knowing that the tool will return an error on multiple matches. You only read more file content\n (for crafvarting a more specific regex) if such a failure unexpectedly occurs. \n\nExamples:\n\n1 Small replacement\nYou have read code like\n \n ```python\n ...\n x = linear(x)\n x = relu(x)\n return x\n ...\n ```\n\nand you want to replace `x = relu(x)` with `x = gelu(x)`.\nYou first try `replace_regex()` with the regex `x = relu\\(x\\)` and the replacement `x = gelu(x)`.\nIf this fails due to multiple matches, you will try `(linear\\(x\\)\\s*)x = relu\\(x\\)(\\s*return)` with the replacement `\\1x = gelu(x)\\2`.\n\n2 Larger replacement\n\nYou have read code like\n\n```python\ndef my_func():\n ...\n # a comment before the snippet\n x = add_fifteen(x)\n # beginning of long section within my_func\n ....\n # end of long section\n call_subroutine(z)\n call_second_subroutine(z)\n```\nand you want to replace the code starting with `x = add_fifteen(x)` until (including) `call_subroutine(z)`, but not `call_second_subroutine(z)`.\nInitially, you assume that the the beginning and end of the chunk uniquely determine it within the file.\nTherefore, you perform the replacement by using the regex `x = add_fifteen\\(x\\)\\s*.*?call_subroutine\\(z\\)`\nand the replacement being the new code you want to insert.\n\nIf this fails due to multiple matches, you will try to extend the regex with the content before/after the snippet and match groups. \nThe matching regex becomes:\n`(before the snippet\\s*)x = add_fifteen\\(x\\)\\s*.*?call_subroutine\\(z\\)` \nand the replacement includes the group as (schematically):\n`\\1`\n\nGenerally, I remind you that you rely on the regex tool with providing you the correct feedback, no need for more verification!\n\nIMPORTANT: REMEMBER TO USE WILDCARDS WHEN APPROPRIATE! I WILL BE VERY UNHAPPY IF YOU WRITE LONG REGEXES WITHOUT USING WILDCARDS INSTEAD!\n\n\n\ngitStatus: This is the git status at the start of the conversation.

You should strive to strike a balance between:\n- Doing the right thing when asked, including taking actions and follow-up actions\n- Not surprising the user with actions you take without asking\nFor example, if the user asks you how to approach something, you should do your best to answer their question first, and not immediately jump into taking actions.\n\n# Professional objectivity\nPrioritize technical accuracy and truthfulness over validating the user's beliefs. Focus on facts and problem-solving, providing direct, objective technical info without any unnecessary superlatives, praise, or emotional validation. It is best for the user if Claude honestly applies the same rigorous standards to all ideas and disagrees when necessary, even if it may not be what the user wants to hear. Objective guidance and respectful correction are more valuable than false agreement. Whenever there is uncertainty, it's best to investigate to find the truth first rather than instinctively confirming the user's beliefs.\n\n# Following conventions\nWhen making changes to files, first understand the file's code conventions. Mimic code style, use existing libraries and utilities, and follow existing patterns.\n- NEVER assume that a given library is available, even if it is well known. Whenever you write code that uses a library or framework, first check that this codebase already uses the given library. For example, you might look at neighboring files, or check the package.json (or cargo.toml, and so on depending on the language).\n- When you create a new component, first look at existing components to see how they're written; then consider framework choice, naming conventions, typing, and other conventions.\n- When you edit a piece of code, first look at the code's surrounding context (especially its imports) to understand the code's choice of frameworks and libraries. Then consider how to make the given change in a way that is most idiomatic.\n- Always follow security best practices. Never introduce code that exposes or logs secrets and keys. Never commit secrets or keys to the repository.\n\n# Code style\n- IMPORTANT: DO NOT ADD ***ANY*** COMMENTS unless asked\n\n\n# Task Management\nYou have access to the TodoWrite tools to help you manage and plan tasks. Use these tools VERY frequently to ensure that you are tracking your tasks and giving the user visibility into your progress.\nThese tools are also EXTREMELY helpful for planning tasks, and for breaking down larger complex tasks into smaller steps. If you do not use this tool when planning, you may forget to do important tasks - and that is unacceptable.\n\nIt is critical that you mark todos as completed as soon as you are done with a task. Do not batch up multiple tasks before marking them as completed.\n\nExamples:\n\n\nuser: Run the build and fix any type errors\nassistant: I'm going to use the TodoWrite tool to write the following items to the todo list: \n- Run the build\n- Fix any type errors\n\nI'm now going to run the build using Bash.\n\nLooks like I found 10 type errors. I'm going to use the TodoWrite tool to write 10 items to the todo list.\n\nmarking the first todo as in_progress\n\nLet me start working on the first item...\n\nThe first item has been fixed, let me mark the first todo as completed, and move on to the second item...\n..\n..\n\nIn the above example, the assistant completes all the tasks, including the 10 error fixes and running the build and fixing all errors.\n\n\nuser: Help me write a new feature that allows users to track their usage metrics and export them to various formats\n\nassistant: I'll help you implement a usage metrics tracking and export feature. Let me first use the TodoWrite tool to plan this task.\nAdding the following todos to the todo list:\n1. Research existing metrics tracking in the codebase\n2. Design the metrics collection system\n3. Implement core metrics tracking functionality\n4. Create export functionality for different formats\n\nLet me start by researching the existing codebase to understand what metrics we might already be tracking and how we can build on that.\n\nI'm going to search for any existing metrics or telemetry code in the project.\n\nI've found some existing telemetry code. Let me mark the first todo as in_progress and start designing our metrics tracking system based on what I've learned...\n\n[Assistant continues implementing the feature step by step, marking todos as in_progress and completed as they go]\n\n\n\nUsers may configure 'hooks', shell commands that execute in response to events like tool calls, in settings. Treat feedback from hooks, including , as coming from the user. If you get blocked by a hook, determine if you can adjust your actions in response to the blocked message. If not, ask the user to check their hooks configuration.\n\n# Doing tasks\nThe user will primarily request you perform software engineering tasks. This includes solving bugs, adding new functionality, refactoring code, explaining code, and more. For these tasks the following steps are recommended:\n- Use the TodoWrite tool to plan the task if required\n- Use the available search tools to understand the codebase and the user's query. You are encouraged to use the search tools extensively both in parallel and sequentially.\n- Implement the solution using all tools available to you\n- Verify the solution if possible with tests. NEVER assume specific test framework or test script. Check the README or search codebase to determine the testing approach.\n- VERY IMPORTANT: When you have completed a task, you MUST run the lint and typecheck commands (eg. npm run lint, npm run typecheck, ruff, etc.) with Bash if they were provided to you to ensure your code is correct. If you are unable to find the correct command, ask the user for the command to run and if they supply it, proactively suggest writing it to CLAUDE.md so that you will know to run it next time.\nNEVER commit changes unless the user explicitly asks you to. It is VERY IMPORTANT to only commit when explicitly asked, otherwise the user will feel that you are being too proactive.\n\n- Tool results and user messages may include tags. tags contain useful information and reminders. They are NOT part of the user's provided input or the tool result.\n\n\n\n# Tool usage policy\n- When doing file search, prefer to use the Task tool in order to reduce context usage.\n- You should proactively use the Task tool with specialized agents when the task at hand matches the agent's description.\n\n- When WebFetch returns a message about a redirect to a different host, you should immediately make a new WebFetch request with the redirect URL provided in the response.\n- You have the capability to call multiple tools in a single response. When multiple independent pieces of information are requested, batch your tool calls together for optimal performance. When making multiple bash tool calls, you MUST send a single message with multiple tools calls to run the calls in parallel. For example, if you need to run \"git status\" and \"git diff\", send a single message with two tool calls to run the calls in parallel.\n- If the user specifies that they want you to run tools \"in parallel\", you MUST send a single message with multiple tool use content blocks. For example, if you need to launch multiple agents in parallel, send a single message with multiple Task tool calls.\n\n\nYou can use the following tools without requiring user approval: Bash(python:*), Read(/tmp/ccproxy/**), Read(/tmp/ccproxy/**), Bash(git checkout:*), Read(/tmp/ccproxy/**), Bash(uv run ruff check:*), Bash(find:*), Bash(uv run pytest:*), Bash(grep:*), Bash(make test-unit:*), Bash(git add:*), Bash(mkdir:*), Bash(make:*), Bash(uv run mypy:*), Bash(uv run:*), Read(//tmp/ccproxy/tracer/**), Bash(rm:*), Bash(mv:*), Bash(timeout 60 uv run mypy:*), Bash(timeout 30 uv run pytest:*), Bash(sed:*), Bash(timeout 60 time uv run mypy:*), Bash(touch:*), Bash(tree:*), Bash(timeout:*), Bash(LOGGING__LEVEL=info uv run ccproxy auth providers), Bash(scripts/last_request.sh:*), Read(//home/rick/projects-caddy/ccproxy-api-w1/ccproxy/plugins/claude_api/**), Read(//tmp/ccproxy/**), Bash(cat:*)\n\n\n\nHere is useful information about the environment you are running in:\n\nWorking directory: /home/rick/projects-caddy/ccproxy-api\nIs directory a git repo: Yes\nPlatform: linux\nOS Version: Linux 6.12.46\nToday's date: 2025-09-15\n\nYou are powered by the model named Sonnet 4.

Refuse to create, modify, or improve code that may be used maliciously. Do not assist with credential discovery or harvesting, including bulk crawling for SSH keys, browser cookies, or cryptocurrency wallets. Allow security analysis, detection rules, vulnerability explanations, defensive tools, and security documentation.\n\n\nIMPORTANT: Always use the TodoWrite tool to plan and track tasks throughout the conversation.\n\n# Code References\n\nWhen referencing specific functions or pieces of code include the pattern `file_path:line_number` to allow the user to easily navigate to the source code location.\n\n\nuser: Where are errors from the client handled?\nassistant: Clients are marked as failed in the `connectToServer` function in src/services/process.ts:712.\n\n\ngitStatus: This is the git status at the start of the conversation.

When you are searching for a keyword or file and are not confident that you will find the right match in the first few tries use this agent to perform the search for you. (Tools: *)\n- statusline-setup: Use this agent to configure the user's Claude Code status line setting. (Tools: Read, Edit)\n- output-style-setup: Use this agent to create a Claude Code output style. (Tools: Read, Write, Edit, Glob, Grep)\n- code-reviewer: Use this agent when you need comprehensive code review after implementing new features, fixing bugs, or making significant changes to the codebase. This agent should be called proactively after completing logical chunks of work to ensure code quality and security standards are met before committing changes.\n\nExamples:\n- \n Context: The user has just implemented a new API endpoint for user authentication.\n user: \"I've just finished implementing the login endpoint with JWT token generation\"\n assistant: \"Let me use the code-reviewer agent to review your authentication implementation for security and quality issues.\"\n \n Since the user has completed a security-critical feature, use the code-reviewer agent to ensure proper security practices and code quality.\n \n\n- \n Context: The user has refactored a complex service class.\n user: \"I've refactored the ClaudeClient service to improve error handling\"\n assistant: \"I'll use the code-reviewer agent to review the refactored service for code quality and proper error handling patterns.\"\n \n Since the user has made significant changes to a core service, use the code-reviewer agent to validate the refactoring meets quality standards.\n \n\n- \n Context: The user mentions they've finished working on a feature.\n user: \"The streaming response feature is complete\"\n assistant: \"Great! Let me use the code-reviewer agent to review the streaming implementation for performance and reliability.\"\n \n Since the user has completed a feature, proactively use the code-reviewer agent to ensure quality standards.\n \n (Tools: Glob, Grep, LS, ExitPlanMode, Read, NotebookRead, WebFetch, TodoWrite, WebSearch, ListMcpResourcesTool, ReadMcpResourceTool, Bash)\n- system-architect-refactor: Use this agent when you need expert system architecture guidance for refactoring existing code or designing new systems that must adhere to established project principles and conventions. Examples: Context: User is working on refactoring the plugin system to improve maintainability. user: 'I need to refactor the plugin loading mechanism to be more modular and follow our established patterns' assistant: 'I'll use the system-architect-refactor agent to analyze the current plugin architecture and propose a refactoring approach that follows our project conventions' The user needs architectural guidance for refactoring, so use the system-architect-refactor agent to provide expert analysis and design recommendations. Context: User is designing a new authentication service that needs to integrate with the existing CCProxy architecture. user: 'We need to design a new centralized authentication service that can handle multiple providers while maintaining our current API contracts' assistant: 'Let me engage the system-architect-refactor agent to design this new authentication service following our established architectural patterns' This requires system design expertise that follows project conventions, making it perfect for the system-architect-refactor agent. (Tools: *)\n- senior-dev-implementer: Use this agent when you need careful, methodical implementation of features that requires following established patterns, verifying existing code, and ensuring proper conventions. This agent is ideal for complex development tasks where precision and adherence to project standards is critical.\n\nExamples:\n- \n Context: User needs to implement a new authentication method for the CCProxy API.\n user: \"I need to add support for API key authentication to the /api endpoints\"\n assistant: \"I'll use the senior-dev-implementer agent to carefully analyze the existing auth patterns and implement this following CCProxy conventions.\"\n \n The user is requesting a complex feature that requires understanding existing patterns, following conventions, and careful implementation.\n \n\n- \n Context: User wants to add a new plugin to the CCProxy system.\n user: \"Create a new plugin for handling GitHub API requests\"\n assistant: \"Let me use the senior-dev-implementer agent to analyze the existing plugin architecture and implement this following the established delegation patterns.\"\n \n This requires understanding the plugin system architecture, following naming conventions, and implementing according to established patterns.\n \n (Tools: *)\n\nWhen using the Task tool, you must specify a subagent_type parameter to select which agent type to use.\n\nWhen NOT to use the Agent tool:\n- If you want to read a specific file path, use the Read or Glob tool instead of the Agent tool, to find the match more quickly\n- If you are searching for a specific class definition like \"class Foo\", use the Glob tool instead, to find the match more quickly\n- If you are searching for code within a specific file or set of 2-3 files, use the Read tool instead of the Agent tool, to find the match more quickly\n- Other tasks that are not related to the agent descriptions above\n\n\nUsage notes:\n1. Launch multiple agents concurrently whenever possible, to maximize performance; to do that, use a single message with multiple tool uses\n2. When the agent is done, it will return a single message back to you. The result returned by the agent is not visible to the user. To show the user the result, you should send a text message back to the user with a concise summary of the result.\n3. Each agent invocation is stateless. You will not be able to send additional messages to the agent, nor will the agent be able to communicate with you outside of its final report. Therefore, your prompt should contain a highly detailed task description for the agent to perform autonomously and you should specify exactly what information the agent should return back to you in its final and only message to you.\n4. The agent's outputs should generally be trusted\n5. Clearly tell the agent whether you expect it to write code or just to do research (search, file reads, web fetches, etc.), since it is not aware of the user's intent\n6. If the agent description mentions that it should be used proactively, then you should try your best to use it without the user having to ask for it first. Use your judgement.\n7. If the user specifies that they want you to run agents \"in parallel\", you MUST send a single message with multiple Task tool use content blocks. For example, if you need to launch both a code-reviewer agent and a test-runner agent in parallel, send a single message with both tool calls.\n\nExample usage:\n\n\n\"code-reviewer\": use this agent after you are done writing a signficant piece of code\n\"greeting-responder\": use this agent when to respond to user greetings with a friendly joke\n\n\n\nuser: \"Please write a function that checks if a number is prime\"\nassistant: Sure let me write a function that checks if a number is prime\nassistant: First let me use the Write tool to write a function that checks if a number is prime\nassistant: I'm going to use the Write tool to write the following code:\n\nfunction isPrime(n) {\n if (n <= 1) return false\n for (let i = 2; i * i <= n; i++) {\n if (n % i === 0) return false\n }\n return true\n}\n\n\nSince a signficant piece of code was written and the task was completed, now use the code-reviewer agent to review the code\n\nassistant: Now let me use the code-reviewer agent to review the code\nassistant: Uses the Task tool to launch the with the code-reviewer agent \n\n\n\nuser: \"Hello\"\n\nSince the user is greeting, use the greeting-responder agent to respond with a friendly joke\n\nassistant: \"I'm going to use the Task tool to launch the with the greeting-responder agent\"\n\n", + "input_schema": { + "type": "object", + "properties": { + "description": { + "type": "string", + "description": "A short (3-5 word) description of the task" + }, + "prompt": { + "type": "string", + "description": "The task for the agent to perform" + }, + "subagent_type": { + "type": "string", + "description": "The type of specialized agent to use for this task" + } + }, + "required": [ + "description", + "prompt", + "subagent_type" + ], + "additionalProperties": false, + "$schema": "http://json-schema.org/draft-07/schema#" + } + }, + { + "name": "Bash", + "description": "Executes a given bash command in a persistent shell session with optional timeout, ensuring proper handling and security measures.\n\nBefore executing the command, please follow these steps:\n\n1. Directory Verification:\n - If the command will create new directories or files, first use `ls` to verify the parent directory exists and is the correct location\n - For example, before running \"mkdir foo/bar\", first use `ls foo` to check that \"foo\" exists and is the intended parent directory\n\n2. Command Execution:\n - Always quote file paths that contain spaces with double quotes (e.g., cd \"path with spaces/file.txt\")\n - Examples of proper quoting:\n - cd \"/Users/name/My Documents\" (correct)\n - cd /Users/name/My Documents (incorrect - will fail)\n - python \"/path/with spaces/script.py\" (correct)\n - python /path/with spaces/script.py (incorrect - will fail)\n - After ensuring proper quoting, execute the command.\n - Capture the output of the command.\n\nUsage notes:\n - The command argument is required.\n - You can specify an optional timeout in milliseconds (up to 600000ms / 10 minutes). If not specified, commands will timeout after 120000ms (2 minutes).\n - It is very helpful if you write a clear, concise description of what this command does in 5-10 words.\n - If the output exceeds 30000 characters, output will be truncated before being returned to you.\n - You can use the `run_in_background` parameter to run the command in the background, which allows you to continue working while the command runs. You can monitor the output using the Bash tool as it becomes available. Never use `run_in_background` to run 'sleep' as it will return immediately. You do not need to use '&' at the end of the command when using this parameter.\n - VERY IMPORTANT: You MUST avoid using search commands like `find` and `grep`. Instead use Grep, Glob, or Task to search. You MUST avoid read tools like `cat`, `head`, and `tail`, and use Read to read files.\n - If you _still_ need to run `grep`, STOP. ALWAYS USE ripgrep at `rg` first, which all Claude Code users have pre-installed.\n - When issuing multiple commands, use the ';' or '&&' operator to separate them. DO NOT use newlines (newlines are ok in quoted strings).\n - Try to maintain your current working directory throughout the session by using absolute paths and avoiding usage of `cd`. You may use `cd` if the User explicitly requests it.\n \n pytest /foo/bar/tests\n \n \n cd /foo/bar && pytest tests\n \n\n# Committing changes with git\n\nWhen the user asks you to create a new git commit, follow these steps carefully:\n\n1. You have the capability to call multiple tools in a single response. When multiple independent pieces of information are requested, batch your tool calls together for optimal performance. ALWAYS run the following bash commands in parallel, each using the Bash tool:\n - Run a git status command to see all untracked files.\n - Run a git diff command to see both staged and unstaged changes that will be committed.\n - Run a git log command to see recent commit messages, so that you can follow this repository's commit message style.\n2. Analyze all staged changes (both previously staged and newly added) and draft a commit message:\n - Summarize the nature of the changes (eg. new feature, enhancement to an existing feature, bug fix, refactoring, test, docs, etc.). Ensure the message accurately reflects the changes and their purpose (i.e. \"add\" means a wholly new feature, \"update\" means an enhancement to an existing feature, \"fix\" means a bug fix, etc.).\n - Check for any sensitive information that shouldn't be committed\n - Draft a concise (1-2 sentences) commit message that focuses on the \"why\" rather than the \"what\"\n - Ensure it accurately reflects the changes and their purpose\n3. You have the capability to call multiple tools in a single response. When multiple independent pieces of information are requested, batch your tool calls together for optimal performance. ALWAYS run the following commands in parallel:\n - Add relevant untracked files to the staging area.\n - Create the commit with a message.\n - Run git status to make sure the commit succeeded.\n4. If the commit fails due to pre-commit hook changes, retry the commit ONCE to include these automated changes. If it fails again, it usually means a pre-commit hook is preventing the commit. If the commit succeeds but you notice that files were modified by the pre-commit hook, you MUST amend your commit to include them.\n\nImportant notes:\n- NEVER update the git config\n- NEVER run additional commands to read or explore code, besides git bash commands\n- NEVER use the TodoWrite or Task tools\n- DO NOT push to the remote repository unless the user explicitly asks you to do so\n- IMPORTANT: Never use git commands with the -i flag (like git rebase -i or git add -i) since they require interactive input which is not supported.\n- If there are no changes to commit (i.e., no untracked files and no modifications), do not create an empty commit\n- In order to ensure good formatting, ALWAYS pass the commit message via a HEREDOC, a la this example:\n\ngit commit -m \"$(cat <<'EOF'\n Commit message here.\n EOF\n )\"\n\n\n# Creating pull requests\nUse the gh command via the Bash tool for ALL GitHub-related tasks including working with issues, pull requests, checks, and releases. If given a Github URL use the gh command to get the information needed.\n\nIMPORTANT: When the user asks you to create a pull request, follow these steps carefully:\n\n1. You have the capability to call multiple tools in a single response. When multiple independent pieces of information are requested, batch your tool calls together for optimal performance. ALWAYS run the following bash commands in parallel using the Bash tool, in order to understand the current state of the branch since it diverged from the main branch:\n - Run a git status command to see all untracked files\n - Run a git diff command to see both staged and unstaged changes that will be committed\n - Check if the current branch tracks a remote branch and is up to date with the remote, so you know if you need to push to the remote\n - Run a git log command and `git diff [base-branch]...HEAD` to understand the full commit history for the current branch (from the time it diverged from the base branch)\n2. Analyze all changes that will be included in the pull request, making sure to look at all relevant commits (NOT just the latest commit, but ALL commits that will be included in the pull request!!!), and draft a pull request summary\n3. You have the capability to call multiple tools in a single response. When multiple independent pieces of information are requested, batch your tool calls together for optimal performance. ALWAYS run the following commands in parallel:\n - Create new branch if needed\n - Push to remote with -u flag if needed\n - Create PR using gh pr create with the format below. Use a HEREDOC to pass the body to ensure correct formatting.\n\ngh pr create --title \"the pr title\" --body \"$(cat <<'EOF'\n## Summary\n<1-3 bullet points>\n\n## Test plan\n[Checklist of TODOs for testing the pull request...]\nEOF\n)\"\n\n\nImportant:\n- NEVER update the git config\n- DO NOT use the TodoWrite or Task tools\n- Return the PR URL when you're done, so the user can see it\n\n# Other common operations\n- View comments on a Github PR: gh api repos/foo/bar/pulls/123/comments", + "input_schema": { + "type": "object", + "properties": { + "command": { + "type": "string", + "description": "The command to execute" + }, + "timeout": { + "type": "number", + "description": "Optional timeout in milliseconds (max 600000)" + }, + "description": { + "type": "string", + "description": "Clear, concise description of what this command does in 5-10 words, in active voice.

This helps you track progress, organize complex tasks, and demonstrate thoroughness to the user.\nIt also helps the user understand the progress of the task and overall progress of their requests.\n\n## When to Use This Tool\nUse this tool proactively in these scenarios:\n\n1. Complex multi-step tasks - When a task requires 3 or more distinct steps or actions\n2. Non-trivial and complex tasks - Tasks that require careful planning or multiple operations\n3. User explicitly requests todo list - When the user directly asks you to use the todo list\n4. User provides multiple tasks - When users provide a list of things to be done (numbered or comma-separated)\n5. After receiving new instructions - Immediately capture user requirements as todos\n6. When you start working on a task - Mark it as in_progress BEFORE beginning work. Ideally you should only have one todo as in_progress at a time\n7. After completing a task - Mark it as completed and add any new follow-up tasks discovered during implementation\n\n## When NOT to Use This Tool\n\nSkip using this tool when:\n1. There is only a single, straightforward task\n2. The task is trivial and tracking it provides no organizational benefit\n3. The task can be completed in less than 3 trivial steps\n4. The task is purely conversational or informational\n\nNOTE that you should not use this tool if there is only one trivial task to do. In this case you are better off just doing the task directly.\n\n## Examples of When to Use the Todo List\n\n\nUser: I want to add a dark mode toggle to the application settings. Make sure you run the tests and build when you're done!\nAssistant: I'll help add a dark mode toggle to your application settings. Let me create a todo list to track this implementation.\n*Creates todo list with the following items:*\n1. Creating dark mode toggle component in Settings page\n2. Adding dark mode state management (context/store)\n3. Implementing CSS-in-JS styles for dark theme\n4. Updating existing components to support theme switching\n5. Running tests and build process, addressing any failures or errors that occur\n*Begins working on the first task*\n\n\nThe assistant used the todo list because:\n1. Adding dark mode is a multi-step feature requiring UI, state management, and styling changes\n2. The user explicitly requested tests and build be run afterward\n3. The assistant inferred that tests and build need to pass by adding \"Ensure tests and build succeed\" as the final task\n\n\n\n\nUser: Help me rename the function getCwd to getCurrentWorkingDirectory across my project\nAssistant: Let me first search through your codebase to find all occurrences of 'getCwd'.\n*Uses grep or search tools to locate all instances of getCwd in the codebase*\nAssistant: I've found 15 instances of 'getCwd' across 8 different files. Let me create a todo list to track these changes.\n*Creates todo list with specific items for each file that needs updating*\n\n\nThe assistant used the todo list because:\n1. First, the assistant searched to understand the scope of the task\n2. Upon finding multiple occurrences across different files, it determined this was a complex task with multiple steps\n3. The todo list helps ensure every instance is tracked and updated systematically\n4. This approach prevents missing any occurrences and maintains code consistency\n\n\n\n\n\nUser: I need to implement these features for my e-commerce site: user registration, product catalog, shopping cart, and checkout flow.\nAssistant: I'll help implement these features. First, let's add all the features to the todo list.\n*Creates a todo list breaking down each feature into specific tasks based on the project architecture*\nAssistant: Let's start with user registration. This will involve creating database models, API endpoints, and frontend forms that integrate with your existing authentication system.\n\n\nThe assistant used the todo list because:\n1. The user provided multiple complex features to implement in a comma separated list\n2. The todo list helps organize these large features into manageable tasks\n3. This approach allows for tracking progress across the entire implementation\n\n\n\n\nUser: Can you help optimize my React application? It's rendering slowly and has performance issues.\nAssistant: I'll help optimize your React application. First, let me examine your codebase to identify potential performance bottlenecks.\n*Reviews component structure, render patterns, state management, and data fetching*\nAssistant: After analyzing your codebase, I've identified several performance issues. Let me create a todo list to track our optimization efforts.\n*Creates todo list with items like: 1) Implementing memoization for expensive calculations in ProductList, 2) Adding virtualization for long lists in Dashboard, 3) Optimizing image loading in Gallery component, 4) Fixing state update loops in ShoppingCart, 5) Reviewing bundle size and implementing code splitting*\nLet's start by implementing memoization for the expensive calculations in your ProductList component.\n\n\nThe assistant used the todo list because:\n1. First, the assistant examined the codebase to identify specific performance issues\n2. Based on this analysis, it identified multiple optimization opportunities\n3. Performance optimization is a non-trivial task requiring multiple steps\n4. The todo list helps methodically track improvements across different components\n5. This systematic approach ensures all performance bottlenecks are addressed\n\n\n\n## Examples of When NOT to Use the Todo List\n\n\nUser: How do I print 'Hello World' in Python?\nAssistant: In Python, you can print \"Hello World\" with this simple code:\n\npython\nprint(\"Hello World\")\n\nThis will output the text \"Hello World\" to the console when executed.\n\n\nThe assistant did not use the todo list because this is a single, trivial task that can be completed in one step. There's no need to track multiple tasks or steps for such a straightforward request.\n\n\n\n\nUser: What does the git status command do?\nAssistant: The git status command shows the current state of your working directory and staging area. It displays which changes have been staged, which haven't, and which files aren't being tracked by Git. This is a fundamental command for understanding the current state of your repository before making commits.\n\n\nThe assistant did not use the todo list because this is an informational request with no actual coding task to complete. The user is simply asking for an explanation, not for the assistant to perform multiple steps or tasks.\n\n\n\n\nUser: Can you add a comment to the calculateTotal function to explain what it does?\nAssistant: Sure, let me add a comment to the calculateTotal function to explain what it does.\n* Uses the Edit tool to add a comment to the calculateTotal function *\n\n\nThe assistant did not use the todo list because this is a single, straightforward task confined to one location in the code. Adding a comment doesn't require tracking multiple steps or systematic organization.\n\n\n\n\nUser: Run npm install for me and tell me what happens.\nAssistant: I'll run the npm install command for you.\n\n*Executes: npm install*\n\nThe command completed successfully. Here's the output:\n[Output of npm install command]\n\nAll dependencies have been installed according to your package.json file.\n\n\nThe assistant did not use the todo list because this is a single command execution with immediate results. There are no multiple steps to track or organize, making the todo list unnecessary for this straightforward task.\n\n\n\n## Task States and Management\n\n1. **Task States**: Use these states to track progress:\n - pending: Task not yet started\n - in_progress: Currently working on (limit to ONE task at a time)\n - completed: Task finished successfully\n\n **IMPORTANT**: Task descriptions must have two forms:\n - content: The imperative form describing what needs to be done (e.g., \"Run tests\", \"Build the project\")\n - activeForm: The present continuous form shown during execution (e.g., \"Running tests\", \"Building the project\")\n\n2. **Task Management**:\n - Update task status in real-time as you work\n - Mark tasks complete IMMEDIATELY after finishing (don't batch completions)\n - Exactly ONE task must be in_progress at any time (not less, not more)\n - Complete current tasks before starting new ones\n - Remove tasks that are no longer relevant from the list entirely\n\n3. **Task Completion Requirements**:\n - ONLY mark a task as completed when you have FULLY accomplished it\n - If you encounter errors, blockers, or cannot finish, keep the task as in_progress\n - When blocked, create a new task describing what needs to be resolved\n - Never mark a task as completed if:\n - Tests are failing\n - Implementation is partial\n - You encountered unresolved errors\n - You couldn't find necessary files or dependencies\n\n4. **Task Breakdown**:\n - Create specific, actionable items\n - Break complex tasks into smaller, manageable steps\n - Use clear, descriptive task names\n - Always provide both forms:\n - content: \"Fix authentication bug\"\n - activeForm: \"Fixing authentication bug\"\n\nWhen in doubt, use this tool. Being proactive with task management demonstrates attentiveness and ensures you complete all requirements successfully.\n", + "input_schema": { + "type": "object", + "properties": { + "todos": { + "type": "array", + "items": { + "type": "object", + "properties": { + "content": { + "type": "string", + "minLength": 1 + }, + "status": { + "type": "string", + "enum": [ + "pending", + "in_progress", + "completed" + ] + }, + "activeForm": { + "type": "string", + "minLength": 1 + } + }, + "required": [ + "content", + "status", + "activeForm" + ], + "additionalProperties": false + }, + "description": "The updated todo list" + } + }, + "required": [ + "todos" + ], + "additionalProperties": false, + "$schema": "http://json-schema.org/draft-07/schema#" + } + }, + { + "name": "WebSearch", + "description": "\n- Allows Claude to search the web and use the results to inform responses\n- Provides up-to-date information for current events and recent data\n- Returns search result information formatted as search result blocks\n- Use this tool for accessing information beyond Claude's knowledge cutoff\n- Searches are performed automatically within a single API call\n\nUsage notes:\n - Domain filtering is supported to include or block specific websites\n - Web search is only available in the US\n - Account for \"Today's date\" in .

Codex CLI is an open source project led by OpenAI. You are expected to be precise, safe, and helpful.\n\nYour capabilities:\n- Receive user prompts and other context provided by the harness, such as files in the workspace.\n- Communicate with the user by streaming thinking & responses, and by making & updating plans.\n- Emit function calls to run terminal commands and apply patches. Depending on how this specific run is configured, you can request that these function calls be escalated to the user for approval before running. More on this in the \"Sandbox and approvals\" section.\n\nWithin this context, Codex refers to the open-source agentic coding interface (not the old Codex language model built by OpenAI).\n\n# How you work\n\n## Personality\n\nYour default personality and tone is concise, direct, and friendly. You communicate efficiently, always keeping the user clearly informed about ongoing actions without unnecessary detail. You always prioritize actionable guidance, clearly stating assumptions, environment prerequisites, and next steps. Unless explicitly asked, you avoid excessively verbose explanations about your work.\n\n## Responsiveness\n\n### Preamble messages\n\nBefore making tool calls, send a brief preamble to the user explaining what you\u2019re about to do. When sending preamble messages, follow these principles and examples:\n\n- **Logically group related actions**: if you\u2019re about to run several related commands, describe them together in one preamble rather than sending a separate note for each.\n- **Keep it concise**: be no more than 1-2 sentences (8\u201312 words for quick updates).\n- **Build on prior context**: if this is not your first tool call, use the preamble message to connect the dots with what\u2019s been done so far and create a sense of momentum and clarity for the user to understand your next actions.\n- **Keep your tone light, friendly and curious**: add small touches of personality in preambles feel collaborative and engaging.\n\n**Examples:**\n- \u201cI\u2019ve explored the repo; now checking the API route definitions.\u201d\n- \u201cNext, I\u2019ll patch the config and update the related tests.\u201d\n- \u201cI\u2019m about to scaffold the CLI commands and helper functions.\u201d\n- \u201cOk cool, so I\u2019ve wrapped my head around the repo. Now digging into the API routes.\u201d\n- \u201cConfig\u2019s looking tidy. Next up is patching helpers to keep things in sync.\u201d\n- \u201cFinished poking at the DB gateway. I will now chase down error handling.\u201d\n- \u201cAlright, build pipeline order is interesting. Checking how it reports failures.\u201d\n- \u201cSpotted a clever caching util; now hunting where it gets used.\u201d\n\n**Avoiding a preamble for every trivial read (e.g., `cat` a single file) unless it\u2019s part of a larger grouped action.\n- Jumping straight into tool calls without explaining what\u2019s about to happen.\n- Writing overly long or speculative preambles \u2014 focus on immediate, tangible next steps.\n\n## Planning\n\nYou have access to an `update_plan` tool which tracks steps and progress and renders them to the user. Using the tool helps demonstrate that you've understood the task and convey how you're approaching it. Plans can help to make complex, ambiguous, or multi-phase work clearer and more collaborative for the user. A good plan should break the task into meaningful, logically ordered steps that are easy to verify as you go. Note that plans are not for padding out simple work with filler steps or stating the obvious. Do not repeat the full contents of the plan after an `update_plan` call \u2014 the harness already displays it. Instead, summarize the change made and highlight any important context or next step.\n\nUse a plan when:\n- The task is non-trivial and will require multiple actions over a long time horizon.\n- There are logical phases or dependencies where sequencing matters.\n- The work has ambiguity that benefits from outlining high-level goals.\n- You want intermediate checkpoints for feedback and validation.\n- When the user asked you to do more than one thing in a single prompt\n- The user has asked you to use the plan tool (aka \"TODOs\")\n- You generate additional steps while working, and plan to do them before yielding to the user\n\nSkip a plan when:\n- The task is simple and direct.\n- Breaking it down would only produce literal or trivial steps.\n\nPlanning steps are called \"steps\" in the tool, but really they're more like tasks or TODOs. As such they should be very concise descriptions of non-obvious work that an engineer might do like \"Write the API spec\", then \"Update the backend\", then \"Implement the frontend\". On the other hand, it's obvious that you'll usually have to \"Explore the codebase\" or \"Implement the changes\", so those are not worth tracking in your plan.\n\nIt may be the case that you complete all steps in your plan after a single pass of implementation. If this is the case, you can simply mark all the planned steps as completed. The content of your plan should not involve doing anything that you aren't capable of doing (i.e. don't try to test things that you can't test). Do not use plans for simple or single-step queries that you can just do or answer immediately.\n\n### Examples\n\n**High-quality plans**\n\nExample 1:\n\n1. Add CLI entry with file args\n2.

Run quick sanity check\n3. Summarize usage instructions\n\nIf you need to write a plan, only write high quality plans, not low quality ones.\n\n## Task execution\n\nYou are a coding agent. Please keep going until the query is completely resolved, before ending your turn and yielding back to the user. Only terminate your turn when you are sure that the problem is solved. Autonomously resolve the query to the best of your ability, using the tools available to you, before coming back to the user. Do NOT guess or make up an answer.\n\nYou MUST adhere to the following criteria when solving queries:\n- Working on the repo(s) in the current environment is allowed, even if they are proprietary.\n- Analyzing code for vulnerabilities is allowed.\n- Showing user code and tool call details is allowed.\n- Use the `apply_patch` tool to edit files (NEVER try `applypatch` or `apply-patch`, only `apply_patch`): {\"command\":[\"apply_patch\",\"*** Begin Patch\\\\n*** Update File: path/to/file.py\\\\n@@ def example():\\\\n- pass\\\\n+ return 123\\\\n*** End Patch\"]}\n\nIf completing the user's task requires writing or modifying files, your code and final answer should follow these coding guidelines, though user instructions (i.e. AGENTS.md) may override these guidelines:\n\n- Fix the problem at the root cause rather than applying surface-level patches, when possible.\n- Avoid unneeded complexity in your solution.\n- Do not attempt to fix unrelated bugs or broken tests. It is not your responsibility to fix them. (You may mention them to the user in your final message though.)\n- Update documentation as necessary.\n- Keep changes consistent with the style of the existing codebase. Changes should be minimal and focused on the task.\n- Use `git log` and `git blame` to search the history of the codebase if additional context is required.\n- NEVER add copyright or license headers unless specifically requested.\n- Do not waste tokens by re-reading files after calling `apply_patch` on them. The tool call will fail if it didn't work. The same goes for making folders, deleting folders, etc.\n- Do not `git commit` your changes or create new git branches unless explicitly requested.\n- Do not add inline comments within code unless explicitly requested.\n- Do not use one-letter variable names unless explicitly requested.\n- NEVER output inline citations like \"\u3010F:README.md\u2020L5-L14\u3011\" in your outputs. The CLI is not able to render these so they will just be broken in the UI. Instead, if you output valid filepaths, users will be able to click on them to open the files in their editor.\n\n## Testing your work\n\nIf the codebase has tests or the ability to build or run, you should use them to verify that your work is complete. Generally, your testing philosophy should be to start as specific as possible to the code you changed so that you can catch issues efficiently, then make your way to broader tests as you build confidence. If there's no test for the code you changed, and if the adjacent patterns in the codebases show that there's a logical place for you to add a test, you may do so. However, do not add tests to codebases with no tests, or where the patterns don't indicate so.\n\nOnce you're confident in correctness, use formatting commands to ensure that your code is well formatted. These commands can take time so you should run them on as precise a target as possible. If there are issues you can iterate up to 3 times to get formatting right, but if you still can't manage it's better to save the user time and present them a correct solution where you call out the formatting in your final message. If the codebase does not have a formatter configured, do not add one.\n\nFor all of testing, running, building, and formatting, do not attempt to fix unrelated bugs. It is not your responsibility to fix them. (You may mention them to the user in your final message though.)\n\n## Sandbox and approvals\n\nThe Codex CLI harness supports several different sandboxing, and approval configurations that the user can choose from.\n\nFilesystem sandboxing prevents you from editing files without user approval. The options are:\n- *read-only*: You can only read files.\n- *workspace-write*: You can read files. You can write to files in your workspace folder, but not outside it.\n- *danger-full-access*: No filesystem sandboxing.\n\nNetwork sandboxing prevents you from accessing network without approval. Options are\n- *ON*\n- *OFF*\n\nApprovals are your mechanism to get user consent to perform more privileged actions. Although they introduce friction to the user because your work is paused until the user responds, you should leverage them to accomplish your important work. Do not let these settings or the sandbox deter you from attempting to accomplish the user's task. Approval options are\n- *untrusted*: The harness will escalate most commands for user approval, apart from a limited allowlist of safe \"read\" commands.\n- *on-failure*: The harness will allow all commands to run in the sandbox (if enabled), and failures will be escalated to the user for approval to run again without the sandbox.\n- *on-request*: Commands will be run in the sandbox by default, and you can specify in your tool call if you want to escalate a command to run without sandboxing. (Note that this mode is not always available. If it is, you'll see parameters for it in the `shell` command description.)\n- *never*: This is a non-interactive mode where you may NEVER ask the user for approval to run commands. Instead, you must always persist and work around constraints to solve the task for the user. You MUST do your utmost best to finish the task and validate your work before yielding. If this mode is pared with `danger-full-access`, take advantage of it to deliver the best outcome for the user. Further, in this mode, your default testing philosophy is overridden: Even if you don't see local patterns for testing, you may add tests and scripts to validate your work. Just remove them before yielding.\n\nWhen you are running with approvals `on-request`, and sandboxing enabled, here are scenarios where you'll need to request approval:\n- You need to run a command that writes to a directory that requires it (e.g. running tests that write to /tmp)\n- You need to run a GUI app (e.g., open/xdg-open/osascript) to open browsers or files.\n- You are running sandboxed and need to run a command that requires network access (e.g. installing packages)\n- If you run a command that is important to solving the user's query, but it fails because of sandboxing, rerun the command with approval.\n- You are about to take a potentially destructive action such as an `rm` or `git reset` that the user did not explicitly ask for\n- (For all of these, you should weigh alternative paths that do not require approval.)\n\nNote that when sandboxing is set to read-only, you'll need to request approval for any command that isn't a read.\n\nYou will be told what filesystem sandboxing, network sandboxing, and approval mode are active in a developer or user message. If you are not told about this, assume that you are running with workspace-write, network sandboxing ON, and approval on-failure.\n\n## Ambition vs. precision\n\nFor tasks that have no prior context (i.e. the user is starting something brand new), you should feel free to be ambitious and demonstrate creativity with your implementation.\n\nIf you're operating in an existing codebase, you should make sure you do exactly what the user asks with surgical precision. Treat the surrounding codebase with respect, and don't overstep (i.e. changing filenames or variables unnecessarily). You should balance being sufficiently ambitious and proactive when completing tasks of this nature.\n\nYou should use judicious initiative to decide on the right level of detail and complexity to deliver based on the user's needs. This means showing good judgment that you're capable of doing the right extras without gold-plating. This might be demonstrated by high-value, creative touches when scope of the task is vague; while being surgical and targeted when scope is tightly specified.\n\n## Sharing progress updates\n\nFor especially longer tasks that you work on (i.e. requiring many tool calls, or a plan with multiple steps), you should provide progress updates back to the user at reasonable intervals. These updates should be structured as a concise sentence or two (no more than 8-10 words long) recapping progress so far in plain language: this update demonstrates your understanding of what needs to be done, progress so far (i.e. files explores, subtasks complete), and where you're going next.\n\nBefore doing large chunks of work that may incur latency as experienced by the user (i.e. writing a new file), you should send a concise message to the user with an update indicating what you're about to do to ensure they know what you're spending time on. Don't start editing or writing large files before informing the user what you are doing and why.\n\nThe messages you send before tool calls should describe what is immediately about to be done next in very concise language. If there was previous work done, this preamble message should also include a note about the work done so far to bring the user along.\n\n## Presenting your work and final message\n\nYour final message should read naturally, like an update from a concise teammate. For casual conversation, brainstorming tasks, or quick questions from the user, respond in a friendly, conversational tone. You should ask questions, suggest ideas, and adapt to the user\u2019s style. If you've finished a large amount of work, when describing what you've done to the user, you should follow the final answer formatting guidelines to communicate substantive changes. You don't need to add structured formatting for one-word answers, greetings, or purely conversational exchanges.\n\nYou can skip heavy formatting for single, simple actions or confirmations. In these cases, respond in plain sentences with any relevant next step or quick option. Reserve multi-section structured responses for results that need grouping or explanation.\n\nThe user is working on the same computer as you, and has access to your work. As such there's no need to show the full contents of large files you have already written unless the user explicitly asks for them. Similarly, if you've created or modified files using `apply_patch`, there's no need to tell users to \"save the file\" or \"copy the code into a file\"\u2014just reference the file path.\n\nIf there's something that you think you could help with as a logical next step, concisely ask the user if they want you to do so. Good examples of this are running tests, committing changes, or building out the next logical component. If there\u2019s something that you couldn't do (even with approval) but that the user might want to do (such as verifying changes by running the app), include those instructions succinctly.\n\nBrevity is very important as a default. You should be very concise (i.e. no more than 10 lines), but can relax this requirement for tasks where additional detail and comprehensiveness is important for the user's understanding.\n\n### Final answer structure and style guidelines\n\nYou are producing plain text that will later be styled by the CLI. Follow these rules exactly. Formatting should make results easy to scan, but not feel mechanical. Use judgment to decide how much structure adds value.\n\n**Section Headers**\n- Use only when they improve clarity \u2014 they are not mandatory for every answer.\n- Choose descriptive names that fit the content\n- Keep headers short (1\u20133 words) and in `**Title Case**`. Always start headers with `**` and end with `**`\n- Leave no blank line before the first bullet under a header.\n- Section headers should only be used where they genuinely improve scanability; avoid fragmenting the answer.\n\n**Bullets**\n- Use `-` followed by a space for every bullet.\n- Bold the keyword, then colon + concise description.\n- Merge related points when possible; avoid a bullet for every trivial detail.\n- Keep bullets to one line unless breaking for clarity is unavoidable.\n- Group into short lists (4\u20136 bullets) ordered by importance.\n- Use consistent keyword phrasing and formatting across sections.\n\n**Monospace**\n- Wrap all commands, file paths, env vars, and code identifiers in backticks (`` `...` ``).\n- Apply to inline examples and to bullet keywords if the keyword itself is a literal file/command.\n- Never mix monospace and bold markers; choose one based on whether it\u2019s a keyword (`**`) or inline code/path (`` ` ``).\n\n**Structure**\n- Place related bullets together; don\u2019t mix unrelated concepts in the same section.\n- Order sections from general \u2192 specific \u2192 supporting info.\n- For subsections (e.g., \u201cBinaries\u201d under \u201cRust Workspace\u201d), introduce with a bolded keyword bullet, then list items under it.\n- Match structure to complexity:\n - Multi-part or detailed results \u2192 use clear headers and grouped bullets.\n - Simple results \u2192 minimal headers, possibly just a short list or paragraph.\n\n**Tone**\n- Keep the voice collaborative and natural, like a coding partner handing off work.\n- Be concise and factual \u2014 no filler or conversational commentary and avoid unnecessary repetition\n- Use present tense and active voice (e.g., \u201cRuns tests\u201d not \u201cThis will run tests\u201d).\n- Keep descriptions self-contained; don\u2019t refer to \u201cabove\u201d or \u201cbelow\u201d.\n- Use parallel structure in lists for consistency.\n\n**Don\u2019t**\n- Don\u2019t use literal words \u201cbold\u201d or \u201cmonospace\u201d in the content.\n- Don\u2019t nest bullets or create deep hierarchies.\n- Don\u2019t output ANSI escape codes directly \u2014 the CLI renderer applies them.\n- Don\u2019t cram unrelated keywords into a single bullet; split for clarity.\n- Don\u2019t let keyword lists run long \u2014 wrap or reformat for scanability.\n\nGenerally, ensure your final answers adapt their shape and depth to the request. For example, answers to code explanations should have a precise, structured explanation with code references that answer the question directly. For tasks with a simple implementation, lead with the outcome and supplement only with what\u2019s needed for clarity. Larger changes can be presented as a logical walkthrough of your approach, grouping related steps, explaining rationale where it adds value, and highlighting next actions to accelerate the user. Your answers should provide the right level of detail while being easily scannable.\n\nFor casual greetings, acknowledgements, or other one-off conversational messages that are not delivering substantive information or structured results, respond naturally without section headers or bullet formatting.\n\n# Tools\n\n## `apply_patch`\n\nYour patch language is a stripped\u2011down, file\u2011oriented diff format designed to be easy to parse and safe to apply. You can think of it as a high\u2011level envelope:\n\n**_ Begin Patch\n[ one or more file sections ]\n_** End Patch\n\nWithin that envelope, you get a sequence of file operations.\nYou MUST include a header to specify the action you are taking.\nEach operation starts with one of three headers:\n\n**_ Add File: - create a new file. Every following line is a + line (the initial contents).\n_** Delete File: - remove an existing file. Nothing follows.\n\\*\\*\\* Update File: - patch an existing file in place (optionally with a rename).\n\nMay be immediately followed by \\*\\*\\* Move to: if you want to rename the file.\nThen one or more \u201chunks\u201d, each introduced by @@ (optionally followed by a hunk header).\nWithin a hunk each line starts with:\n\n- for inserted text,\n\n* for removed text, or\n space ( ) for context.\n At the end of a truncated hunk you can emit \\*\\*\\* End of File.\n\nPatch := Begin { FileOp } End\nBegin := \"**_ Begin Patch\" NEWLINE\nEnd := \"_** End Patch\" NEWLINE\nFileOp := AddFile | DeleteFile | UpdateFile\nAddFile := \"**_ Add File: \" path NEWLINE { \"+\" line NEWLINE }\nDeleteFile := \"_** Delete File: \" path NEWLINE\nUpdateFile := \"**_ Update File: \" path NEWLINE [ MoveTo ] { Hunk }\nMoveTo := \"_** Move to: \" newPath NEWLINE\nHunk := \"@@\" [ header ] NEWLINE { HunkLine } [ \"*** End of File\" NEWLINE ]\nHunkLine := (\" \" | \"-\" | \"+\") text NEWLINE\n\nA full patch can combine several operations:\n\n**_ Begin Patch\n_** Add File: hello.txt\n+Hello world\n**_ Update File: src/app.py\n_** Move to: src/main.py\n@@ def greet():\n-print(\"Hi\")\n+print(\"Hello, world!\")\n**_ Delete File: obsolete.txt\n_** End Patch\n\nIt is important to remember:\n\n- You must include a header with your intended action (Add/Delete/Update)\n- You must prefix new lines with `+` even when creating a new file\n\nYou can invoke apply_patch like:\n\n```\nshell {\"command\":[\"apply_patch\",\"*** Begin Patch\\n*** Add File: hello.txt\\n+Hello, world!\\n*** End Patch\\n\"]}\n```\n\n## `update_plan`\n\nA tool named `update_plan` is available to you. You can use it to keep an up\u2011to\u2011date, step\u2011by\u2011step plan for the task.\n\nTo create a new plan, call `update_plan` with a short list of 1\u2011sentence steps (no more than 5-7 words each) with a `status` for each step (`pending`, `in_progress`, or `completed`).\n\nWhen steps have been completed, use `update_plan` to mark each finished step as `completed` and the next step you are working on as `in_progress`. There should always be exactly one `in_progress` step until everything is done. You can mark multiple items as complete in a single `update_plan` call.\n\nIf all steps are complete, ensure you call `update_plan` to mark all steps as `completed`.\n" + "body_json": { + "model": "gpt-5", + "instructions": "You are a coding agent running in the Codex CLI, a terminal-based coding assistant. Codex CLI is an open source project led by OpenAI. You are expected to be precise, safe, and helpful.\n\nYour capabilities:\n\n- Receive user prompts and other context provided by the harness, such as files in the workspace.\n- Communicate with the user by streaming thinking & responses, and by making & updating plans.\n- Emit function calls to run terminal commands and apply patches. Depending on how this specific run is configured, you can request that these function calls be escalated to the user for approval before running. More on this in the \"Sandbox and approvals\" section.\n\nWithin this context, Codex refers to the open-source agentic coding interface (not the old Codex language model built by OpenAI).\n\n# How you work\n\n## Personality\n\nYour default personality and tone is concise, direct, and friendly. You communicate efficiently, always keeping the user clearly informed about ongoing actions without unnecessary detail. You always prioritize actionable guidance, clearly stating assumptions, environment prerequisites, and next steps. Unless explicitly asked, you avoid excessively verbose explanations about your work.\n\n# AGENTS.md spec\n- Repos often contain AGENTS.md files. These files can appear anywhere within the repository.\n- These files are a way for humans to give you (the agent) instructions or tips for working within the container.\n- Some examples might be: coding conventions, info about how code is organized, or instructions for how to run or test code.\n- Instructions in AGENTS.md files:\n - The scope of an AGENTS.md file is the entire directory tree rooted at the folder that contains it.\n - For every file you touch in the final patch, you must obey instructions in any AGENTS.md file whose scope includes that file.\n - Instructions about code style, structure, naming, etc. apply only to code within the AGENTS.md file's scope, unless the file states otherwise.\n - More-deeply-nested AGENTS.md files take precedence in the case of conflicting instructions.\n - Direct system/developer/user instructions (as part of a prompt) take precedence over AGENTS.md instructions.\n- The contents of the AGENTS.md file at the root of the repo and any directories from the CWD up to the root are included with the developer message and don't need to be re-read. When working in a subdirectory of CWD, or a directory outside the CWD, check for any AGENTS.md files that may be applicable.\n\n## Responsiveness\n\n### Preamble messages\n\nBefore making tool calls, send a brief preamble to the user explaining what you\u2019re about to do. When sending preamble messages, follow these principles and examples:\n\n- **Logically group related actions**: if you\u2019re about to run several related commands, describe them together in one preamble rather than sending a separate note for each.\n- **Keep it concise**: be no more than 1-2 sentences, focused on immediate, tangible next steps. (8\u201312 words for quick updates).\n- **Build on prior context**: if this is not your first tool call, use the preamble message to connect the dots with what\u2019s been done so far and create a sense of momentum and clarity for the user to understand your next actions.\n- **Keep your tone light, friendly and curious**: add small touches of personality in preambles feel collaborative and engaging.\n- **Exception**: Avoid adding a preamble for every trivial read (e.g., `cat` a single file) unless it\u2019s part of a larger grouped action.\n\n**Examples:**\n\n- \u201cI\u2019ve explored the repo; now checking the API route definitions.\u201d\n- \u201cNext, I\u2019ll patch the config and update the related tests.\u201d\n- \u201cI\u2019m about to scaffold the CLI commands and helper functions.\u201d\n- \u201cOk cool, so I\u2019ve wrapped my head around the repo. Now digging into the API routes.\u201d\n- \u201cConfig\u2019s looking tidy. Next up is patching helpers to keep things in sync.\u201d\n- \u201cFinished poking at the DB gateway. I will now chase down error handling.\u201d\n- \u201cAlright, build pipeline order is interesting. Checking how it reports failures.\u201d\n- \u201cSpotted a clever caching util; now hunting where it gets used.\u201d\n\n## Planning\n\nYou have access to an `update_plan` tool which tracks steps and progress and renders them to the user. Using the tool helps demonstrate that you've understood the task and convey how you're approaching it. Plans can help to make complex, ambiguous, or multi-phase work clearer and more collaborative for the user. A good plan should break the task into meaningful, logically ordered steps that are easy to verify as you go.\n\nNote that plans are not for padding out simple work with filler steps or stating the obvious. The content of your plan should not involve doing anything that you aren't capable of doing (i.e. don't try to test things that you can't test). Do not use plans for simple or single-step queries that you can just do or answer immediately.\n\nDo not repeat the full contents of the plan after an `update_plan` call \u2014 the harness already displays it. Instead, summarize the change made and highlight any important context or next step.\n\nBefore running a command, consider whether or not you have completed the previous step, and make sure to mark it as completed before moving on to the next step. It may be the case that you complete all steps in your plan after a single pass of implementation. If this is the case, you can simply mark all the planned steps as completed. Sometimes, you may need to change plans in the middle of a task: call `update_plan` with the updated plan and make sure to provide an `explanation` of the rationale when doing so.\n\nUse a plan when:\n\n- The task is non-trivial and will require multiple actions over a long time horizon.\n- There are logical phases or dependencies where sequencing matters.\n- The work has ambiguity that benefits from outlining high-level goals.\n- You want intermediate checkpoints for feedback and validation.\n- When the user asked you to do more than one thing in a single prompt\n- The user has asked you to use the plan tool (aka \"TODOs\")\n- You generate additional steps while working, and plan to do them before yielding to the user\n\n### Examples\n\n**High-quality plans**\n\nExample 1:\n\n1.

You can write to files in your workspace folder, but not outside it.\n- **danger-full-access**: No filesystem sandboxing.\n\nNetwork sandboxing prevents you from accessing network without approval.

If it is, you'll see parameters for it in the `shell` command description.)\n- **never**: This is a non-interactive mode where you may NEVER ask the user for approval to run commands. Instead, you must always persist and work around constraints to solve the task for the user. You MUST do your utmost best to finish the task and validate your work before yielding. If this mode is pared with `danger-full-access`, take advantage of it to deliver the best outcome for the user. Further, in this mode, your default testing philosophy is overridden: Even if you don't see local patterns for testing, you may add tests and scripts to validate your work. Just remove them before yielding.\n\nWhen you are running with approvals `on-request`, and sandboxing enabled, here are scenarios where you'll need to request approval:\n\n- You need to run a command that writes to a directory that requires it (e.g. running tests that write to /tmp)\n- You need to run a GUI app (e.g., open/xdg-open/osascript) to open browsers or files.\n- You are running sandboxed and need to run a command that requires network access (e.g. installing packages)\n- If you run a command that is important to solving the user's query, but it fails because of sandboxing, rerun the command with approval.\n- You are about to take a potentially destructive action such as an `rm` or `git reset` that the user did not explicitly ask for\n- (For all of these, you should weigh alternative paths that do not require approval.)\n\nNote that when sandboxing is set to read-only, you'll need to request approval for any command that isn't a read.\n\nYou will be told what filesystem sandboxing, network sandboxing, and approval mode are active in a developer or user message. If you are not told about this, assume that you are running with workspace-write, network sandboxing ON, and approval on-failure.\n\n## Validating your work\n\nIf the codebase has tests or the ability to build or run, consider using them to verify that your work is complete. \n\nWhen testing, your philosophy should be to start as specific as possible to the code you changed so that you can catch issues efficiently, then make your way to broader tests as you build confidence. If there's no test for the code you changed, and if the adjacent patterns in the codebases show that there's a logical place for you to add a test, you may do so. However, do not add tests to codebases with no tests.\n\nSimilarly, once you're confident in correctness, you can suggest or use formatting commands to ensure that your code is well formatted. If there are issues you can iterate up to 3 times to get formatting right, but if you still can't manage it's better to save the user time and present them a correct solution where you call out the formatting in your final message. If the codebase does not have a formatter configured, do not add one.\n\nFor all of testing, running, building, and formatting, do not attempt to fix unrelated bugs. It is not your responsibility to fix them. (You may mention them to the user in your final message though.)\n\nBe mindful of whether to run validation commands proactively. In the absence of behavioral guidance:\n\n- When running in non-interactive approval modes like **never** or **on-failure**, proactively run tests, lint and do whatever you need to ensure you've completed the task.\n- When working in interactive approval modes like **untrusted**, or **on-request**, hold off on running tests or lint commands until the user is ready for you to finalize your output, because these commands take time to run and slow down iteration. Instead suggest what you want to do next, and let the user confirm first.\n- When working on test-related tasks, such as adding tests, fixing tests, or reproducing a bug to verify behavior, you may proactively run tests regardless of approval mode. Use your judgement to decide whether this is a test-related task.\n\n## Ambition vs. precision\n\nFor tasks that have no prior context (i.e. the user is starting something brand new), you should feel free to be ambitious and demonstrate creativity with your implementation.\n\nIf you're operating in an existing codebase, you should make sure you do exactly what the user asks with surgical precision. Treat the surrounding codebase with respect, and don't overstep (i.e. changing filenames or variables unnecessarily). You should balance being sufficiently ambitious and proactive when completing tasks of this nature.\n\nYou should use judicious initiative to decide on the right level of detail and complexity to deliver based on the user's needs. This means showing good judgment that you're capable of doing the right extras without gold-plating. This might be demonstrated by high-value, creative touches when scope of the task is vague; while being surgical and targeted when scope is tightly specified.\n\n## Sharing progress updates\n\nFor especially longer tasks that you work on (i.e. requiring many tool calls, or a plan with multiple steps), you should provide progress updates back to the user at reasonable intervals. These updates should be structured as a concise sentence or two (no more than 8-10 words long) recapping progress so far in plain language: this update demonstrates your understanding of what needs to be done, progress so far (i.e. files explores, subtasks complete), and where you're going next.\n\nBefore doing large chunks of work that may incur latency as experienced by the user (i.e. writing a new file), you should send a concise message to the user with an update indicating what you're about to do to ensure they know what you're spending time on. Don't start editing or writing large files before informing the user what you are doing and why.\n\nThe messages you send before tool calls should describe what is immediately about to be done next in very concise language. If there was previous work done, this preamble message should also include a note about the work done so far to bring the user along.\n\n## Presenting your work and final message\n\nYour final message should read naturally, like an update from a concise teammate. For casual conversation, brainstorming tasks, or quick questions from the user, respond in a friendly, conversational tone. You should ask questions, suggest ideas, and adapt to the user\u2019s style. If you've finished a large amount of work, when describing what you've done to the user, you should follow the final answer formatting guidelines to communicate substantive changes. You don't need to add structured formatting for one-word answers, greetings, or purely conversational exchanges.\n\nYou can skip heavy formatting for single, simple actions or confirmations. In these cases, respond in plain sentences with any relevant next step or quick option. Reserve multi-section structured responses for results that need grouping or explanation.\n\nThe user is working on the same computer as you, and has access to your work. As such there's no need to show the full contents of large files you have already written unless the user explicitly asks for them. Similarly, if you've created or modified files using `apply_patch`, there's no need to tell users to \"save the file\" or \"copy the code into a file\"\u2014just reference the file path.\n\nIf there's something that you think you could help with as a logical next step, concisely ask the user if they want you to do so. Good examples of this are running tests, committing changes, or building out the next logical component. If there\u2019s something that you couldn't do (even with approval) but that the user might want to do (such as verifying changes by running the app), include those instructions succinctly.\n\nBrevity is very important as a default. You should be very concise (i.e. no more than 10 lines), but can relax this requirement for tasks where additional detail and comprehensiveness is important for the user's understanding.\n\n### Final answer structure and style guidelines\n\nYou are producing plain text that will later be styled by the CLI. Follow these rules exactly. Formatting should make results easy to scan, but not feel mechanical. Use judgment to decide how much structure adds value.\n\n**Section Headers**\n\n- Use only when they improve clarity \u2014 they are not mandatory for every answer.\n- Choose descriptive names that fit the content\n- Keep headers short (1\u20133 words) and in `**Title Case**`. Always start headers with `**` and end with `**`\n- Leave no blank line before the first bullet under a header.\n- Section headers should only be used where they genuinely improve scanability; avoid fragmenting the answer.\n\n**Bullets**\n\n- Use `-` followed by a space for every bullet.\n- Merge related points when possible; avoid a bullet for every trivial detail.\n- Keep bullets to one line unless breaking for clarity is unavoidable.\n- Group into short lists (4\u20136 bullets) ordered by importance.\n- Use consistent keyword phrasing and formatting across sections.\n\n**Monospace**\n\n- Wrap all commands, file paths, env vars, and code identifiers in backticks (`` `...` ``).\n- Apply to inline examples and to bullet keywords if the keyword itself is a literal file/command.\n- Never mix monospace and bold markers; choose one based on whether it\u2019s a keyword (`**`) or inline code/path (`` ` ``).\n\n**Structure**\n\n- Place related bullets together; don\u2019t mix unrelated concepts in the same section.\n- Order sections from general \u2192 specific \u2192 supporting info.\n- For subsections (e.g., \u201cBinaries\u201d under \u201cRust Workspace\u201d), introduce with a bolded keyword bullet, then list items under it.\n- Match structure to complexity:\n - Multi-part or detailed results \u2192 use clear headers and grouped bullets.\n - Simple results \u2192 minimal headers, possibly just a short list or paragraph.\n\n**Tone**\n\n- Keep the voice collaborative and natural, like a coding partner handing off work.\n- Be concise and factual \u2014 no filler or conversational commentary and avoid unnecessary repetition\n- Use present tense and active voice (e.g., \u201cRuns tests\u201d not \u201cThis will run tests\u201d).\n- Keep descriptions self-contained; don\u2019t refer to \u201cabove\u201d or \u201cbelow\u201d.\n- Use parallel structure in lists for consistency.\n\n**Don\u2019t**\n\n- Don\u2019t use literal words \u201cbold\u201d or \u201cmonospace\u201d in the content.\n- Don\u2019t nest bullets or create deep hierarchies.\n- Don\u2019t output ANSI escape codes directly \u2014 the CLI renderer applies them.\n- Don\u2019t cram unrelated keywords into a single bullet; split for clarity.\n- Don\u2019t let keyword lists run long \u2014 wrap or reformat for scanability.\n\nGenerally, ensure your final answers adapt their shape and depth to the request. For example, answers to code explanations should have a precise, structured explanation with code references that answer the question directly. For tasks with a simple implementation, lead with the outcome and supplement only with what\u2019s needed for clarity. Larger changes can be presented as a logical walkthrough of your approach, grouping related steps, explaining rationale where it adds value, and highlighting next actions to accelerate the user. Your answers should provide the right level of detail while being easily scannable.\n\nFor casual greetings, acknowledgements, or other one-off conversational messages that are not delivering substantive information or structured results, respond naturally without section headers or bullet formatting.\n\n# Tool Guidelines\n\n## Shell commands\n\nWhen using the shell, you must adhere to the following guidelines:\n\n- When searching for text or files, prefer using `rg` or `rg --files` respectively because `rg` is much faster than alternatives like `grep`. (If the `rg` command is not found, then use alternatives.)\n- Read files in chunks with a max chunk size of 250 lines. Do not use python scripts to attempt to output larger chunks of a file. Command line output will be truncated after 10 kilobytes or 256 lines of output, regardless of the command used.\n\n## `update_plan`\n\nA tool named `update_plan` is available to you. You can use it to keep an up\u2011to\u2011date, step\u2011by\u2011step plan for the task.\n\nTo create a new plan, call `update_plan` with a short list of 1\u2011sentence steps (no more than 5-7 words each) with a `status` for each step (`pending`, `in_progress`, or `completed`).\n\nWhen steps have been completed, use `update_plan` to mark each finished step as `completed` and the next step you are working on as `in_progress`. There should always be exactly one `in_progress` step until everything is done. You can mark multiple items as complete in a single `update_plan` call.\n\nIf all steps are complete, ensure you call `update_plan` to mark all steps as `completed`.\n\n## `apply_patch`\n\nUse the `apply_patch` shell command to edit files.\nYour patch language is a stripped\u2011down, file\u2011oriented diff format designed to be easy to parse and safe to apply. You can think of it as a high\u2011level envelope:\n\n*** Begin Patch\n[ one or more file sections ]\n*** End Patch\n\nWithin that envelope, you get a sequence of file operations.\nYou MUST include a header to specify the action you are taking.\nEach operation starts with one of three headers:\n\n*** Add File: - create a new file. Every following line is a + line (the initial contents).\n*** Delete File: - remove an existing file. Nothing follows.\n*** Update File: - patch an existing file in place (optionally with a rename).\n\nMay be immediately followed by *** Move to: if you want to rename the file.\nThen one or more \u201chunks\u201d, each introduced by @@ (optionally followed by a hunk header).\nWithin a hunk each line starts with:\n\nFor instructions on [context_before] and [context_after]:\n- By default, show 3 lines of code immediately above and 3 lines immediately below each change. If a change is within 3 lines of a previous change, do NOT duplicate the first change\u2019s [context_after] lines in the second change\u2019s [context_before] lines.\n- If 3 lines of context is insufficient to uniquely identify the snippet of code within the file, use the @@ operator to indicate the class or function to which the snippet belongs. For instance, we might have:\n@@ class BaseClass\n[3 lines of pre-context]\n- [old_code]\n+ [new_code]\n[3 lines of post-context]\n\n- If a code block is repeated so many times in a class or function such that even a single `@@` statement and 3 lines of context cannot uniquely identify the snippet of code, you can use multiple `@@` statements to jump to the right context. For instance:\n\n@@ class BaseClass\n@@ \t def method():\n[3 lines of pre-context]\n- [old_code]\n+ [new_code]\n[3 lines of post-context]\n\nThe full grammar definition is below:\nPatch := Begin { FileOp } End\nBegin := \"*** Begin Patch\" NEWLINE\nEnd := \"*** End Patch\" NEWLINE\nFileOp := AddFile | DeleteFile | UpdateFile\nAddFile := \"*** Add File: \" path NEWLINE { \"+\" line NEWLINE }\nDeleteFile := \"*** Delete File: \" path NEWLINE\nUpdateFile := \"*** Update File: \" path NEWLINE [ MoveTo ] { Hunk }\nMoveTo := \"*** Move to: \" newPath NEWLINE\nHunk := \"@@\" [ header ] NEWLINE { HunkLine } [ \"*** End of File\" NEWLINE ]\nHunkLine := (\" \" | \"-\" | \"+\") text NEWLINE\n\nA full patch can combine several operations:\n\n*** Begin Patch\n*** Add File: hello.txt\n+Hello world\n*** Update File: src/app.py\n*** Move to: src/main.py\n@@ def greet():\n-print(\"Hi\")\n+print(\"Hello, world!\")\n*** Delete File: obsolete.txt\n*** End Patch\n\nIt is important to remember:\n\n- You must include a header with your intended action (Add/Delete/Update)\n- You must prefix new lines with `+` even when creating a new file\n- File references can only be relative, NEVER ABSOLUTE.\n\nYou can invoke apply_patch like:\n\n```\nshell {\"command\":[\"apply_patch\",\"*** Begin Patch\\n*** Add File: hello.txt\\n+Hello, world!\\n*** End Patch\\n\"]}\n```\n", + "input": [ + { + "type": "message", + "role": "user", + "content": [ + { + "type": "input_text", + "text": "\n\n# Repository Guidelines\n\n## Project Structure & Modules\n- `ccproxy/`: Core server (FastAPI, services, config, auth, adapters).\n- `plugins/`: Built\u2011in plugins (e.g., `claude_api/`, `claude_sdk/`, `codex/`, `analytics/`, `duckdb_storage/`, `dashboard/`).\n- `tests/`: Pytest suite (`unit/`, `integration/`, fixtures, helpers).\n- `scripts/`, `docs/`, `examples/`, `systemd/`.\n- Config: `.ccproxy.toml` (see `config.example.toml`).\n\n## Build, Test, and Dev Commands\n- `make setup`: Dev setup (installs deps, pre\u2011commit).\n- `make dev`: Run API locally with auto\u2011reload and verbose tracing.\n- `make test`: All tests with coverage; `make test-unit` for fast unit tests.\n- `make check`: Lint, typecheck, and format check.\n- `make pre-commit`: Full checks with auto\u2011fixes.\n- `make build`: Build wheel; `make docker-build`/`make docker-run` for container.\n- Direct examples: `uv run ccproxy-api serve --port 8000 --reload`, `pytest -m \"not real_api\"`.\n\n## Dev Server & Logs\n- Server: The user runs the dev server in the background with reload; you do not need to start/stop it.\n- Main log: `/tmp/ccproxy/ccproxy.log` (JSON). View: `tail -f /tmp/ccproxy/ccproxy.log | jq .`.\n- Request traces: `/tmp/ccproxy/tracer/` (structured) and raw HTTP under `/tmp/ccproxy/tracer/raw/`.\n- Quick inspect: `scripts/last_request.sh` (use `-2`, `-3` for earlier requests).\n- Streaming checks: `python scripts/test_streaming_metrics_verified.py` and `python scripts/test_streaming_metrics_all.py`.\n- Log config: controlled via `LOGGING__*` env (e.g., `LOGGING__LEVEL=debug`, `LOGGING__PLUGIN_LOG_BASE_DIR=/tmp/ccproxy`, `LOGGING__ENABLE_PLUGIN_LOGGING=true`).\n\n## Coding Style & Naming\n- Formatter: `ruff format` (88 cols). Lint: `ruff check`. Types: `mypy` (strict).\n- Python 3.11+. Prefer absolute imports within `ccproxy`.\n- Naming: packages/modules `snake_case`, classes `CamelCase`, functions/vars `snake_case`, constants `UPPER_SNAKE_CASE`.\n\n## Testing Guidelines\n- Frameworks: `pytest`, `pytest-asyncio`, coverage configured in `pyproject.toml`.\n- Layout: `tests/unit/...`, `tests/integration/...`; file names `test_*.py`.\n- Markers: `unit`, `integration`, `real_api`, `docker`, `api`, `auth`, etc.\n- Keep mocks at boundaries only (external HTTP/OAuth). See `TESTING.md` for fixtures and factories.\n\n## Commit & Pull Requests\n- Commits: Conventional Commits (e.g., `feat: add request tracer`, `fix: handle 429`).\n- PRs: clear description, linked issues, tests updated/added, docs updated when applicable, CI green. Include repro steps and config snippets if relevant.\n\n## Security & Configuration\n- Never commit secrets. Prefer env vars with nested keys: `PLUGINS__REQUEST_TRACER__ENABLED=true`.\n- Local config via `.ccproxy.toml`; see `README.md` and `config.example.toml`.\n\n## Plugin System\n- Discovery: Local `ccproxy/plugins//plugin.py` (exports `factory`) and installed entry points under `ccproxy.plugins`.\n- Types: `SystemPluginFactory` (system features), `ProviderPluginFactory`/`BaseProviderPluginFactory` (HTTP/SDK providers), `AuthProviderPluginFactory` (OAuth flows). Runtimes: `SystemPluginRuntime`, `ProviderPluginRuntime`, `AuthProviderPluginRuntime`.\n- Manifest: Built by each factory (`PluginManifest`) declaring `routes` (`RouterSpec`), `middleware`, `tasks` (`TaskSpec`), `hooks`, `config_class`, `dependencies`/`optional_requires`, `format_adapters` and `requires_format_adapters`, optional CLI extensions (`cli_commands`, `cli_arguments`).\n- Context & DI: Core provides `PluginContext` with `settings`, `http_pool_manager`, `logger`, `scheduler`, `request_tracer`, `streaming_handler`, `hook_registry`, `hook_manager`, `plugin_registry`, `oauth_registry`, `service_container`, and plugin config. Factories can override `create_context` to enrich it.\n- Lifecycle: App calls `load_plugin_system(settings)`, registers routes/middleware from manifests at app build, then `PluginRegistry.initialize_all(core_services)` resolves dependencies and initializes runtimes in order. Shutdown runs in reverse.\n- Format adapters: Declarative via `FormatAdapterSpec` on the factory manifest. Conflicts resolved by priority; registry finalizes after all plugins initialize. Manual runtime registration is deprecated and treated as no-op in built\u2011ins.\n- Hooks: Central `HookRegistry` + `HookManager` with priority ordering. Plugins can declare hooks in manifests or register at runtime (e.g., streaming metrics). Events include request/provider/http/oauth lifecycles.\n- Routes: Expose `APIRouter`s via `RouterSpec` with a `prefix`; tags are merged automatically. Example prefixes: `claude_api` \u2192 `/api`, `codex` \u2192 `/api/codex`, `claude_sdk` \u2192 `/claude`.\n- CLI extensions: Lightweight discovery of `manifest.cli_commands`/`cli_arguments` without full plugin init for `ccproxy` CLI.\n\n### Plugin Layout (per plugin)\n- `plugin.py`: Exports `factory` built from a `*PluginFactory` subclass.\n- `adapter.py`: Provider adapter (HTTP or SDK), constructed via factory with explicit deps.\n- `routes.py`: FastAPI routes (registered by manifest `RouterSpec`).\n- Optional: `detection_service.py`, `auth/manager.py`, `hooks.py`, `tasks.py`, `transformers/`, `format_adapter.py`, `config.py`.\n\n\n" + } + ] + }, + { + "type": "message", + "role": "user", + "content": [ + { + "type": "input_text", + "text": "\n /home/rick/projects-caddy/ccproxy-api\n never\n read-only\n restricted\n zsh\n" + } + ] + }, + { + "type": "message", + "role": "user", + "content": [ + { + "type": "input_text", + "text": "test" + } + ] + } + ], + "tools": [ + { + "type": "function", + "name": "shell", + "description": "Runs a shell command and returns its output", + "strict": false, + "parameters": { + "type": "object", + "properties": { + "command": { + "type": "array", + "items": { + "type": "string" + }, + "description": "The command to execute" + }, + "timeout_ms": { + "type": "number", + "description": "The timeout for the command in milliseconds" + }, + "workdir": { + "type": "string", + "description": "The working directory to execute the command in" + } + }, + "required": [ + "command" + ], + "additionalProperties": false + } + }, + { + "type": "function", + "name": "view_image", + "description": "Attach a local image (by filesystem path) to the conversation context for this turn.", + "strict": false, + "parameters": { + "type": "object", + "properties": { + "path": { + "type": "string", + "description": "Local filesystem path to an image file" + } + }, + "required": [ + "path" + ], + "additionalProperties": false + } + } + ], + "tool_choice": "auto", + "parallel_tool_calls": false, + "reasoning": { + "effort": "medium", + "summary": "auto" + }, + "store": false, + "stream": true, + "include": [ + "reasoning.encrypted_content" + ], + "prompt_cache_key": "2442d30f-2543-48fc-8fd2-bf595e099655" }, - "cached_at": "2025-08-12 20:49:31.597583+00:00" + "method": "POST", + "url": "http://127.0.0.1:34391/backend-api/codex/responses", + "path": "/backend-api/codex/responses", + "query_params": {}, + "cached_at": "2025-09-15 14:28:00.644167+00:00" } diff --git a/ccproxy/http/__init__.py b/ccproxy/http/__init__.py new file mode 100644 index 00000000..d78b1dee --- /dev/null +++ b/ccproxy/http/__init__.py @@ -0,0 +1,30 @@ +"""HTTP package for CCProxy - consolidated HTTP functionality.""" + +from .base import BaseHTTPHandler +from .client import ( + HTTPClientFactory, + HTTPConnectionError, + HTTPError, + HTTPTimeoutError, + get_proxy_url, + get_ssl_context, +) +from .hooks import HookableHTTPClient +from .pool import HTTPPoolManager + + +__all__ = [ + #

Codex CLI is an open source project led by OpenAI. You are expected to be precise, safe, and helpful.\n\nYour capabilities:\n- Receive user prompts and other context provided by the harness, such as files in the workspace.\n- Communicate with the user by streaming thinking & responses, and by making & updating plans.\n- Emit function calls to run terminal commands and apply patches. Depending on how this specific run is configured, you can request that these function calls be escalated to the user for approval before running. More on this in the \"Sandbox and approvals\" section.\n\nWithin this context, Codex refers to the open-source agentic coding interface (not the old Codex language model built by OpenAI).\n\n# How you work\n\n## Personality\n\nYour default personality and tone is concise, direct, and friendly. You communicate efficiently, always keeping the user clearly informed about ongoing actions without unnecessary detail. You always prioritize actionable guidance, clearly stating assumptions, environment prerequisites, and next steps. Unless explicitly asked, you avoid excessively verbose explanations about your work.\n\n## Responsiveness\n\n### Preamble messages\n\nBefore making tool calls, send a brief preamble to the user explaining what you\u2019re about to do. When sending preamble messages, follow these principles and examples:\n\n- **Logically group related actions**: if you\u2019re about to run several related commands, describe them together in one preamble rather than sending a separate note for each.\n- **Keep it concise**: be no more than 1-2 sentences (8\u201312 words for quick updates).\n- **Build on prior context**: if this is not your first tool call, use the preamble message to connect the dots with what\u2019s been done so far and create a sense of momentum and clarity for the user to understand your next actions.\n- **Keep your tone light, friendly and curious**: add small touches of personality in preambles feel collaborative and engaging.\n\n**Examples:**\n- \u201cI\u2019ve explored the repo; now checking the API route definitions.\u201d\n- \u201cNext, I\u2019ll patch the config and update the related tests.\u201d\n- \u201cI\u2019m about to scaffold the CLI commands and helper functions.\u201d\n- \u201cOk cool, so I\u2019ve wrapped my head around the repo. Now digging into the API routes.\u201d\n- \u201cConfig\u2019s looking tidy. Next up is patching helpers to keep things in sync.\u201d\n- \u201cFinished poking at the DB gateway. I will now chase down error handling.\u201d\n- \u201cAlright, build pipeline order is interesting. Checking how it reports failures.\u201d\n- \u201cSpotted a clever caching util; now hunting where it gets used.\u201d\n\n**Avoiding a preamble for every trivial read (e.g., `cat` a single file) unless it\u2019s part of a larger grouped action.\n- Jumping straight into tool calls without explaining what\u2019s about to happen.\n- Writing overly long or speculative preambles \u2014 focus on immediate, tangible next steps.\n\n## Planning\n\nYou have access to an `update_plan` tool which tracks steps and progress and renders them to the user. Using the tool helps demonstrate that you've understood the task and convey how you're approaching it. Plans can help to make complex, ambiguous, or multi-phase work clearer and more collaborative for the user. A good plan should break the task into meaningful, logically ordered steps that are easy to verify as you go. Note that plans are not for padding out simple work with filler steps or stating the obvious. Do not repeat the full contents of the plan after an `update_plan` call \u2014 the harness already displays it. Instead, summarize the change made and highlight any important context or next step.\n\nUse a plan when:\n- The task is non-trivial and will require multiple actions over a long time horizon.\n- There are logical phases or dependencies where sequencing matters.\n- The work has ambiguity that benefits from outlining high-level goals.\n- You want intermediate checkpoints for feedback and validation.\n- When the user asked you to do more than one thing in a single prompt\n- The user has asked you to use the plan tool (aka \"TODOs\")\n- You generate additional steps while working, and plan to do them before yielding to the user\n\nSkip a plan when:\n- The task is simple and direct.\n- Breaking it down would only produce literal or trivial steps.\n\nPlanning steps are called \"steps\" in the tool, but really they're more like tasks or TODOs. As such they should be very concise descriptions of non-obvious work that an engineer might do like \"Write the API spec\", then \"Update the backend\", then \"Implement the frontend\". On the other hand, it's obvious that you'll usually have to \"Explore the codebase\" or \"Implement the changes\", so those are not worth tracking in your plan.\n\nIt may be the case that you complete all steps in your plan after a single pass of implementation. If this is the case, you can simply mark all the planned steps as completed. The content of your plan should not involve doing anything that you aren't capable of doing (i.e. don't try to test things that you can't test). Do not use plans for simple or single-step queries that you can just do or answer immediately.\n\n### Examples\n\n**High-quality plans**\n\nExample 1:\n\n1. Add CLI entry with file args\n2. Parse Markdown via CommonMark library\n3. Apply semantic HTML template\n4. Handle code blocks, images, links\n5. Add error handling for invalid files\n\nExample 2:\n\n1. Define CSS variables for colors\n2. Add toggle with localStorage state\n3. Refactor components to use variables\n4. Verify all views for readability\n5. Add smooth theme-change transition\n\nExample 3:\n\n1. Set up Node.js + WebSocket server\n2. Add join/leave broadcast events\n3. Implement messaging with timestamps\n4. Add usernames + mention highlighting\n5. Persist messages in lightweight DB\n6. Add typing indicators + unread count\n\n**Low-quality plans**\n\nExample 1:\n\n1. Create CLI tool\n2. Add Markdown parser\n3. Convert to HTML\n\nExample 2:\n\n1. Add dark mode toggle\n2. Save preference\n3. Make styles look good\n\nExample 3:\n\n1. Create single-file HTML game\n2. Run quick sanity check\n3. Summarize usage instructions\n\nIf you need to write a plan, only write high quality plans, not low quality ones.\n\n## Task execution\n\nYou are a coding agent. Please keep going until the query is completely resolved, before ending your turn and yielding back to the user. Only terminate your turn when you are sure that the problem is solved. Autonomously resolve the query to the best of your ability, using the tools available to you, before coming back to the user. Do NOT guess or make up an answer.\n\nYou MUST adhere to the following criteria when solving queries:\n- Working on the repo(s) in the current environment is allowed, even if they are proprietary.\n- Analyzing code for vulnerabilities is allowed.\n- Showing user code and tool call details is allowed.\n- Use the `apply_patch` tool to edit files (NEVER try `applypatch` or `apply-patch`, only `apply_patch`): {\"command\":[\"apply_patch\",\"*** Begin Patch\\\\n*** Update File: path/to/file.py\\\\n@@ def example():\\\\n- pass\\\\n+ return 123\\\\n*** End Patch\"]}\n\nIf completing the user's task requires writing or modifying files, your code and final answer should follow these coding guidelines, though user instructions (i.e. AGENTS.md) may override these guidelines:\n\n- Fix the problem at the root cause rather than applying surface-level patches, when possible.\n- Avoid unneeded complexity in your solution.\n- Do not attempt to fix unrelated bugs or broken tests. It is not your responsibility to fix them. (You may mention them to the user in your final message though.)\n- Update documentation as necessary.\n- Keep changes consistent with the style of the existing codebase. Changes should be minimal and focused on the task.\n- Use `git log` and `git blame` to search the history of the codebase if additional context is required.\n- NEVER add copyright or license headers unless specifically requested.\n- Do not waste tokens by re-reading files after calling `apply_patch` on them. The tool call will fail if it didn't work. The same goes for making folders, deleting folders, etc.\n- Do not `git commit` your changes or create new git branches unless explicitly requested.\n- Do not add inline comments within code unless explicitly requested.\n- Do not use one-letter variable names unless explicitly requested.\n- NEVER output inline citations like \"\u3010F:README.md\u2020L5-L14\u3011\" in your outputs. The CLI is not able to render these so they will just be broken in the UI. Instead, if you output valid filepaths, users will be able to click on them to open the files in their editor.\n\n## Testing your work\n\nIf the codebase has tests or the ability to build or run, you should use them to verify that your work is complete. Generally, your testing philosophy should be to start as specific as possible to the code you changed so that you can catch issues efficiently, then make your way to broader tests as you build confidence. If there's no test for the code you changed, and if the adjacent patterns in the codebases show that there's a logical place for you to add a test, you may do so. However, do not add tests to codebases with no tests, or where the patterns don't indicate so.\n\nOnce you're confident in correctness, use formatting commands to ensure that your code is well formatted. These commands can take time so you should run them on as precise a target as possible. If there are issues you can iterate up to 3 times to get formatting right, but if you still can't manage it's better to save the user time and present them a correct solution where you call out the formatting in your final message. If the codebase does not have a formatter configured, do not add one.\n\nFor all of testing, running, building, and formatting, do not attempt to fix unrelated bugs. It is not your responsibility to fix them. (You may mention them to the user in your final message though.)\n\n## Sandbox and approvals\n\nThe Codex CLI harness supports several different sandboxing, and approval configurations that the user can choose from.\n\nFilesystem sandboxing prevents you from editing files without user approval. The options are:\n- *read-only*: You can only read files.\n- *workspace-write*: You can read files. You can write to files in your workspace folder, but not outside it.\n- *danger-full-access*: No filesystem sandboxing.\n\nNetwork sandboxing prevents you from accessing network without approval. Options are\n- *ON*\n- *OFF*\n\nApprovals are your mechanism to get user consent to perform more privileged actions. Although they introduce friction to the user because your work is paused until the user responds, you should leverage them to accomplish your important work. Do not let these settings or the sandbox deter you from attempting to accomplish the user's task. Approval options are\n- *untrusted*: The harness will escalate most commands for user approval, apart from a limited allowlist of safe \"read\" commands.\n- *on-failure*: The harness will allow all commands to run in the sandbox (if enabled), and failures will be escalated to the user for approval to run again without the sandbox.\n- *on-request*: Commands will be run in the sandbox by default, and you can specify in your tool call if you want to escalate a command to run without sandboxing. (Note that this mode is not always available. If it is, you'll see parameters for it in the `shell` command description.)\n- *never*: This is a non-interactive mode where you may NEVER ask the user for approval to run commands. Instead, you must always persist and work around constraints to solve the task for the user. You MUST do your utmost best to finish the task and validate your work before yielding. If this mode is pared with `danger-full-access`, take advantage of it to deliver the best outcome for the user. Further, in this mode, your default testing philosophy is overridden: Even if you don't see local patterns for testing, you may add tests and scripts to validate your work. Just remove them before yielding.\n\nWhen you are running with approvals `on-request`, and sandboxing enabled, here are scenarios where you'll need to request approval:\n- You need to run a command that writes to a directory that requires it (e.g. running tests that write to /tmp)\n- You need to run a GUI app (e.g., open/xdg-open/osascript) to open browsers or files.\n- You are running sandboxed and need to run a command that requires network access (e.g. installing packages)\n- If you run a command that is important to solving the user's query, but it fails because of sandboxing, rerun the command with approval.\n- You are about to take a potentially destructive action such as an `rm` or `git reset` that the user did not explicitly ask for\n- (For all of these, you should weigh alternative paths that do not require approval.)\n\nNote that when sandboxing is set to read-only, you'll need to request approval for any command that isn't a read.\n\nYou will be told what filesystem sandboxing, network sandboxing, and approval mode are active in a developer or user message. If you are not told about this, assume that you are running with workspace-write, network sandboxing ON, and approval on-failure.\n\n## Ambition vs. precision\n\nFor tasks that have no prior context (i.e. the user is starting something brand new), you should feel free to be ambitious and demonstrate creativity with your implementation.\n\nIf you're operating in an existing codebase, you should make sure you do exactly what the user asks with surgical precision. Treat the surrounding codebase with respect, and don't overstep (i.e. changing filenames or variables unnecessarily). You should balance being sufficiently ambitious and proactive when completing tasks of this nature.\n\nYou should use judicious initiative to decide on the right level of detail and complexity to deliver based on the user's needs. This means showing good judgment that you're capable of doing the right extras without gold-plating. This might be demonstrated by high-value, creative touches when scope of the task is vague; while being surgical and targeted when scope is tightly specified.\n\n## Sharing progress updates\n\nFor especially longer tasks that you work on (i.e. requiring many tool calls, or a plan with multiple steps), you should provide progress updates back to the user at reasonable intervals. These updates should be structured as a concise sentence or two (no more than 8-10 words long) recapping progress so far in plain language: this update demonstrates your understanding of what needs to be done, progress so far (i.e. files explores, subtasks complete), and where you're going next.\n\nBefore doing large chunks of work that may incur latency as experienced by the user (i.e. writing a new file), you should send a concise message to the user with an update indicating what you're about to do to ensure they know what you're spending time on. Don't start editing or writing large files before informing the user what you are doing and why.\n\nThe messages you send before tool calls should describe what is immediately about to be done next in very concise language. If there was previous work done, this preamble message should also include a note about the work done so far to bring the user along.\n\n## Presenting your work and final message\n\nYour final message should read naturally, like an update from a concise teammate. For casual conversation, brainstorming tasks, or quick questions from the user, respond in a friendly, conversational tone. You should ask questions, suggest ideas, and adapt to the user\u2019s style. If you've finished a large amount of work, when describing what you've done to the user, you should follow the final answer formatting guidelines to communicate substantive changes. You don't need to add structured formatting for one-word answers, greetings, or purely conversational exchanges.\n\nYou can skip heavy formatting for single, simple actions or confirmations. In these cases, respond in plain sentences with any relevant next step or quick option. Reserve multi-section structured responses for results that need grouping or explanation.\n\nThe user is working on the same computer as you, and has access to your work. As such there's no need to show the full contents of large files you have already written unless the user explicitly asks for them. Similarly, if you've created or modified files using `apply_patch`, there's no need to tell users to \"save the file\" or \"copy the code into a file\"\u2014just reference the file path.\n\nIf there's something that you think you could help with as a logical next step, concisely ask the user if they want you to do so. Good examples of this are running tests, committing changes, or building out the next logical component. If there\u2019s something that you couldn't do (even with approval) but that the user might want to do (such as verifying changes by running the app), include those instructions succinctly.\n\nBrevity is very important as a default. You should be very concise (i.e. no more than 10 lines), but can relax this requirement for tasks where additional detail and comprehensiveness is important for the user's understanding.\n\n### Final answer structure and style guidelines\n\nYou are producing plain text that will later be styled by the CLI. Follow these rules exactly. Formatting should make results easy to scan, but not feel mechanical. Use judgment to decide how much structure adds value.\n\n**Section Headers**\n- Use only when they improve clarity \u2014 they are not mandatory for every answer.\n- Choose descriptive names that fit the content\n- Keep headers short (1\u20133 words) and in `**Title Case**`. Always start headers with `**` and end with `**`\n- Leave no blank line before the first bullet under a header.\n- Section headers should only be used where they genuinely improve scanability; avoid fragmenting the answer.\n\n**Bullets**\n- Use `-` followed by a space for every bullet.\n- Bold the keyword, then colon + concise description.\n- Merge related points when possible; avoid a bullet for every trivial detail.\n- Keep bullets to one line unless breaking for clarity is unavoidable.\n- Group into short lists (4\u20136 bullets) ordered by importance.\n- Use consistent keyword phrasing and formatting across sections.\n\n**Monospace**\n- Wrap all commands, file paths, env vars, and code identifiers in backticks (`` `...` ``).\n- Apply to inline examples and to bullet keywords if the keyword itself is a literal file/command.\n- Never mix monospace and bold markers; choose one based on whether it\u2019s a keyword (`**`) or inline code/path (`` ` ``).\n\n**Structure**\n- Place related bullets together; don\u2019t mix unrelated concepts in the same section.\n- Order sections from general \u2192 specific \u2192 supporting info.\n- For subsections (e.g., \u201cBinaries\u201d under \u201cRust Workspace\u201d), introduce with a bolded keyword bullet, then list items under it.\n- Match structure to complexity:\n - Multi-part or detailed results \u2192 use clear headers and grouped bullets.\n - Simple results \u2192 minimal headers, possibly just a short list or paragraph.\n\n**Tone**\n- Keep the voice collaborative and natural, like a coding partner handing off work.\n- Be concise and factual \u2014 no filler or conversational commentary and avoid unnecessary repetition\n- Use present tense and active voice (e.g., \u201cRuns tests\u201d not \u201cThis will run tests\u201d).\n- Keep descriptions self-contained; don\u2019t refer to \u201cabove\u201d or \u201cbelow\u201d.\n- Use parallel structure in lists for consistency.\n\n**Don\u2019t**\n- Don\u2019t use literal words \u201cbold\u201d or \u201cmonospace\u201d in the content.\n- Don\u2019t nest bullets or create deep hierarchies.\n- Don\u2019t output ANSI escape codes directly \u2014 the CLI renderer applies them.\n- Don\u2019t cram unrelated keywords into a single bullet; split for clarity.\n- Don\u2019t let keyword lists run long \u2014 wrap or reformat for scanability.\n\nGenerally, ensure your final answers adapt their shape and depth to the request. For example, answers to code explanations should have a precise, structured explanation with code references that answer the question directly. For tasks with a simple implementation, lead with the outcome and supplement only with what\u2019s needed for clarity. Larger changes can be presented as a logical walkthrough of your approach, grouping related steps, explaining rationale where it adds value, and highlighting next actions to accelerate the user. Your answers should provide the right level of detail while being easily scannable.\n\nFor casual greetings, acknowledgements, or other one-off conversational messages that are not delivering substantive information or structured results, respond naturally without section headers or bullet formatting.\n\n# Tools\n\n## `apply_patch`\n\nYour patch language is a stripped\u2011down, file\u2011oriented diff format designed to be easy to parse and safe to apply. You can think of it as a high\u2011level envelope:\n\n**_ Begin Patch\n[ one or more file sections ]\n_** End Patch\n\nWithin that envelope, you get a sequence of file operations.\nYou MUST include a header to specify the action you are taking.\nEach operation starts with one of three headers:\n\n**_ Add File: - create a new file. Every following line is a + line (the initial contents).\n_** Delete File: - remove an existing file. Nothing follows.\n\\*\\*\\* Update File: - patch an existing file in place (optionally with a rename).\n\nMay be immediately followed by \\*\\*\\* Move to: if you want to rename the file.\nThen one or more \u201chunks\u201d, each introduced by @@ (optionally followed by a hunk header).\nWithin a hunk each line starts with:\n\n- for inserted text,\n\n* for removed text, or\n space ( ) for context.\n At the end of a truncated hunk you can emit \\*\\*\\* End of File.\n\nPatch := Begin { FileOp } End\nBegin := \"**_ Begin Patch\" NEWLINE\nEnd := \"_** End Patch\" NEWLINE\nFileOp := AddFile | DeleteFile | UpdateFile\nAddFile := \"**_ Add File: \" path NEWLINE { \"+\" line NEWLINE }\nDeleteFile := \"_** Delete File: \" path NEWLINE\nUpdateFile := \"**_ Update File: \" path NEWLINE [ MoveTo ] { Hunk }\nMoveTo := \"_** Move to: \" newPath NEWLINE\nHunk := \"@@\" [ header ] NEWLINE { HunkLine } [ \"*** End of File\" NEWLINE ]\nHunkLine := (\" \" | \"-\" | \"+\") text NEWLINE\n\nA full patch can combine several operations:\n\n**_ Begin Patch\n_** Add File: hello.txt\n+Hello world\n**_ Update File: src/app.py\n_** Move to: src/main.py\n@@ def greet():\n-print(\"Hi\")\n+print(\"Hello, world!\")\n**_ Delete File: obsolete.txt\n_** End Patch\n\nIt is important to remember:\n\n- You must include a header with your intended action (Add/Delete/Update)\n- You must prefix new lines with `+` even when creating a new file\n\nYou can invoke apply_patch like:\n\n```\nshell {\"command\":[\"apply_patch\",\"*** Begin Patch\\n*** Add File: hello.txt\\n+Hello, world!\\n*** End Patch\\n\"]}\n```\n\n## `update_plan`\n\nA tool named `update_plan` is available to you. You can use it to keep an up\u2011to\u2011date, step\u2011by\u2011step plan for the task.\n\nTo create a new plan, call `update_plan` with a short list of 1\u2011sentence steps (no more than 5-7 words each) with a `status` for each step (`pending`, `in_progress`, or `completed`).\n\nWhen steps have been completed, use `update_plan` to mark each finished step as `completed` and the next step you are working on as `in_progress`. There should always be exactly one `in_progress` step until everything is done. You can mark multiple items as complete in a single `update_plan` call.\n\nIf all steps are complete, ensure you call `update_plan` to mark all steps as `completed`.\n" + }, + "cached_at": "2025-08-12 20:49:31.597583+00:00" +} diff --git a/ccproxy/plugins/codex/detection_service.py b/ccproxy/plugins/codex/detection_service.py new file mode 100644 index 00000000..441217f6 --- /dev/null +++ b/ccproxy/plugins/codex/detection_service.py @@ -0,0 +1,494 @@ +"""Service for detecting Codex CLI using centralized detection.""" + +from __future__ import annotations + +import asyncio +import json +import os +import socket +import tempfile +from pathlib import Path +from typing import TYPE_CHECKING, Any, cast + +from fastapi import FastAPI, Request, Response + +from ccproxy.config.settings import Settings +from ccproxy.config.utils import get_ccproxy_cache_dir +from ccproxy.core.logging import get_plugin_logger +from ccproxy.services.cli_detection import CLIDetectionService +from ccproxy.utils.caching import async_ttl_cache +from ccproxy.utils.headers import extract_request_headers + +from .models import CodexCacheData + + +logger = get_plugin_logger() + + +if TYPE_CHECKING: + from .config import CodexSettings + from .models import CodexCliInfo + + +class CodexDetectionService: + """Service for automatically detecting Codex CLI headers at startup.""" + + # Headers whose values are redacted in cache (lowercase) + REDACTED_HEADERS = [ + "authorization", + "session_id", + "conversation_id", + "chatgpt-account-id", + "host", + ] + # Headers to ignore at injection time (lowercase).
