+# CLAUDE.md
+
+This file provides guidance to Claude Code when working with this repository.
+
+## Project Overview
+
+**DSPy Code** is an AI-powered interactive development environment (IDE) for building and optimizing DSPy applications. It provides a specialized CLI that helps developers:
+
+- Develop DSPy applications using natural language
+- Optimize with GEPA (Genetic Pareto) workflows
+- Validate code against DSPy best practices
+- Deploy production-ready applications using MCP integration
+
+**Status:** Beta (v0.1.5)
+**Python:** 3.10, 3.11, 3.12, 3.13
+

+
+## Development Commands
+
+### Setup
+
+```bash
+# Using uv (recommended)
+uv venv
+source .venv/bin/activate
+uv pip install -e ".[dev,test,docs]"
+
+# Install pre-commit hooks
+pre-commit install
+```
+
+### Testing
+
+```bash
+# Run all tests
+pytest
+
+# Run with coverage
+pytest --cov=dspy_code --cov-report=html
+
+# Run specific test file
+pytest tests/test_specific_file.py
+
+# Run in parallel
+pytest -n auto
+
+# Run by marker
+pytest -m unit           # Unit tests only
+pytest -m integration    # Integration tests only
+pytest -m "not slow"     # Skip slow tests
+```
+
+### Linting and Formatting
+
+```bash
+# Run linter
+ruff check .
+
+# Fix linting issues
+ruff check --fix .
+
+# Run formatter
+ruff format .
+
+# Type checking
+mypy dspy_code
+```
+
+### Building
+
+```bash
+# Build package
+python -m build
+
+# Check package
+twine check dist/*
+```
+
+## Code Style
+
+- **Linter/Formatter:** Ruff
+- **Line length:** 100 characters
+- **Type hints:** Required for function signatures
+- **Docstrings:** Google-style format
+- **Imports:** Organized by Ruff (stdlib, third-party, local)
+
+## Commit Conventions
+
+Use [Conventional Commits](https://www.conventionalcommits.org/):
+
+- `feat:` - New features
+- `fix:` - Bug fixes
+- `docs:` - Documentation changes
+- `style:` - Formatting changes
+- `refactor:` - Code restructuring
+- `test:` - Test additions/changes
+- `chore:` - Maintenance tasks
+
+## Key Dependencies
+
+- **dspy>=3.0.4** - Core DSPy framework
+- **click>=8.0.0** - CLI framework
+- **rich>=13.7.0** - Terminal UI
+- **mcp>=1.2.1** - Model Context Protocol
+- **pydantic>=2.11.0** - Data validation
+
+## Important Notes
+
+- This project uses `hatchling` as the build backend (no setup.py)
+- Entry point: `dspy-code` command maps to `dspy_code.main:main`
+- Tests use pytest with markers: `unit`, `integration`, `slow`
+- Pre-commit hooks enforce quality standards
+- CI requires passing all Python versions (3.10-3.13)
+
+## Documentation
+
+- **Main docs:** `docs/` directory (MkDocs)
+- **API reference:** Docstrings in source code
+- **Changelog:** `CHANGELOG.md` (Keep a Changelog format)
+- **Contributing:** `CONTRIBUTING.md`
+
+## LLM Providers
+
+Optional dependencies for different providers:
+- `dspy-code[openai]` - OpenAI support
+- `dspy-code[anthropic]` - Anthropic support
+- `dspy-code[gemini]` - Google Gemini support
+- `dspy-code[llm-all]` - All providers
