+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+X-Profiler is a Node.js native addon for runtime profiling and performance monitoring. It outputs performance logs at regular intervals and enables real-time runtime state sampling via external commands (xprofctl CLI).
+
+**Supported Platforms:** Windows, Linux (x64/arm64), macOS (x64/arm64)
+**Node.js Versions:** v18.x, v20.x, v22.x, v24.x (LTS only)
+
+## Build Commands
+
+```bash
+# Build the native addon (requires C++ toolchain)
+npm run build
+
+# Build with pre-built binary download (fallback to build from source)
+npm install
+
+# Run all tests
+npm run test
+
+# Run a single test file
+npm run test-single test/config.test.js
+
+# Generate coverage report
+npm run cov
+
+# Run coverage for a single test
+npm run cov-single test/config.test.js
+
+# Full CI suite (lint + build + coverage)
+npm run ci
+
+# Format C++ code (requires clang-format)
+npm run format
+
+# Lint JavaScript code
+npm run lint
+```
+
+## Build System & C++ Compilation
+
+**C++ Standard Requirements:**
+- Linux: Uses C++17 (`-std=c++17` in `cflags`)
+- macOS: Uses C++20 (`-std=c++20` in `xcode_settings.OTHER_CFLAGS`) - required for Node.js v24+
+- Windows: Uses MSVC default settings
+
+The project uses:
+- **node-gyp** for native compilation
+- **@mapbox/node-pre-gyp** for binary distribution via GitHub Releases
+- **NAN (Native Abstractions for Node.js)** for V8 API compatibility
+
+Build output: `build/binding/Release/node-v{abi}-{platform}-{arch}/xprofiler.node`
+
+## Architecture
+
+### Multi-Threading Model
+
+The addon runs **three concurrent threads**:
+
+1. **Main Thread** - JavaScript execution, configuration, API calls
+2. **LogBypass Thread** - Periodic statistics collection (separate libuv loop)
+3. **CommandsListener Thread** - IPC socket server accepting xprofctl commands
+
+### Code Organization
+
+**JavaScript Layer** (`/lib/`, `/patch/`, root):
+- `xprofiler.js` - Main entry point and public API
+- `lib/configure.js` - Configuration merging (env vars → defaults → user config)
+- `patch/http.js` - HTTP module patching via diagnostics_channel (Node.js v18+)
+
+**Native C++ Layer** (`/src/`):
+
+**Core:**
+- `xprofiler.cc` - Module initialization, NAN bindings export
+- `environment_data.h/cc` - Per-isolate profiling state
+- `environment_registry.h/cc` - Multi-isolate management
+
+**JavaScript Bindings** (`/src/jsapi/`):
+- Bridge between JS and C++ (export_configure, export_logger, export_http, etc.)
+
+**Statistics Collection** (`/src/logbypass/`):
+- Runs in separate thread, samples at `log_interval` (default 60s)
+- Collects: CPU, heap, GC, libuv handles, HTTP metrics
+
+**Remote Commands** (`/src/commands/`):
+- IPC listener accepts commands from `xprofctl` CLI
+- Profiling: CPU profiling, heap profiling, heap snapshots, GC profiling
+- Diagnostics: Reports (JS/native stacks, heap stats, UV stats, system info)
+- Simple: version, config get/set
+
+**Platform-Specific** (`/src/platform/`):
+- `unix/` - Linux/macOS (Unix sockets, /proc/stat, getrusage)
+- `win/` - Windows (named pipes, Performance Counters, DbgHelp)
+
+**V8 Hooks** (`/src/hooks/`):
+- `fatal_error.cc` - FatalError handler (can trigger diagnostics/coredump)
+- `heap_limit.cc` - Auto-increment heap limit on OOM
+
+## Configuration System
+
+**3-Level Priority:**
+```
+User Config (xprofiler.start({...}))  [highest]
+    ↓
+Environment Variables (XPROFILER_*)
+    ↓
+Default Config (configuration.js)     [lowest]
+```
+
+**Key Configurations:**
+- `log_dir` - Output directory (default: `os.tmpdir()`)
+- `log_interval` - Sampling interval in seconds (default: 60)
+- `log_format_alinode` - Alinode format compatibility (default: false)
+- `patch_http` - Enable HTTP patching (default: true)
+- `enable_fatal_error_hook` - FatalError handling (default: true)
+- `enable_auto_incr_heap_limit` - Auto-grow heap on OOM (default: false)
+
+See `configuration.js` for full list and README.md for environment variable names.
+
+## Testing
+
+**Framework:** Mocha + expect.js
+**Coverage:** nyc (Istanbul)
+
+**Test Structure:**
+- `/test/*.test.js` - Unit tests for core features
+- `/test/patch/*.test.js` - Module patching tests
+- `/test/fixtures/` - Test helpers and utilities
+
+**Important:** Tests use `mm` library for mocking. Always call `mm.restore()` in afterEach hooks.
+
+## Common Development Tasks
+
+### Adding a New Configuration Option
+
+1. Add default value to `configuration.js`
+2. Add environment variable parsing to `lib/configure.js`
+3. Update native config struct in `src/configure.h`
+4. Add JS binding in `src/jsapi/export_configure.cc`
+5. Add test to `test/config.test.js`
+
+### Adding a New xprofctl Command
+
+1. Define command in `src/commands/parser.cc`
+2. Implement handler in appropriate `src/commands/*/` subdirectory
+3. Add command output logic in `src/commands/dump.cc`
+4. Update `bin/xprofctl` CLI with new command/args
+5. Add test to `test/commands.test.js`
+
+### Modifying Statistics Collection
+
+1. Update data structures in `src/library/common.h`
+2. Modify collection logic in `src/logbypass/*.cc`
+3. Update output formatting in logger
+4. Add test to `test/logbypass.test.js`
+
+## Platform-Specific Considerations
+
+**Linux:**
+- CPU stats via `/proc/stat` parsing
+- Coredump support via `src/platform/unix/core/linux/`
+- glibc mallopt configuration
+
+**macOS:**
+- CPU stats via `getrusage()`
+- Stack traces via macOS-specific APIs
+- No coredump support
+
+**Windows:**
+- Named pipes for IPC (not Unix sockets)
+- Windows Performance Counters for CPU
+- DbgHelp.dll for stack traces
+- Different path handling (`\\.\pipe\xprofiler-ctl`)
+
+## IPC Protocol
+
+**Socket Path:**
+- Unix: `<log_dir>/xprofiler-ctl-uds-path.sock`
+- Windows: `\\.\pipe\xprofiler-ctl`
+
+**Command Format:** JSON messages between xprofctl and CommandsListener thread
+
+**Output Location:** Profiling artifacts saved to `log_dir` with timestamps
+
+## CI/CD
+
+**GitHub Actions:** `.github/workflows/nodejs.yml`
+- Matrix: 3 OS × 4 Node.js versions
+- Steps: Build → Test → Coverage → Upload to codecov
+- Runs on every commit
+
+**Binary Distribution:**
+- Pre-built binaries released to GitHub Releases
+- node-pre-gyp downloads matching binary during npm install
+- Fallback to source compilation if binary unavailable
+
+## Important Notes
+
+- **Thread Safety:** Use `xpf_mutex.h` for synchronization between threads
+- **V8 Isolation:** Use `RequestInterrupt()` for safe cross-thread V8 access
+- **NAN Deprecations:** Some NAN APIs are deprecated in Node.js v24 (warnings are non-critical)
+- **Log Format:** Two formats supported (xprofiler native vs Alinode compatibility)
+- **Process Tracking:** Uses `~/.xprofiler` file to track running processes with xprofiler enabled
