# Trace Claude Code to Braintrust

Automatically send Claude Code conversations to Braintrust for tracing and observability. Get full visibility into your AI coding sessions with hierarchical traces showing sessions, turns, and every tool call.

## What you get

```
Claude Code Session (root trace)
├── Turn 1: "Add error handling"
│   ├── Read: src/app.ts
│   ├── Edit: src/app.ts
│   └── Response: "I've added try-catch..."
├── Turn 2: "Now run the tests"
│   ├── Terminal: npm test
│   └── Response: "All tests pass..."
└── Turn 3: "Great, commit this"
    ├── Terminal: git add .
    ├── Terminal: git commit -m "..."
    └── Response: "Changes committed..."
```

## How it works

Four hooks capture the complete workflow:

| Hook | What it captures |
|------|------------------|
| **SessionStart** | Creates root trace when you start Claude Code |
| **PostToolUse** | Captures every tool call (file reads, edits, terminal commands) |
| **Stop** | Captures conversation turns (your message + Claude's response) |
| **SessionEnd** | Logs session summary when you exit |

## Quick setup

Run the setup script in any project directory where you want tracing:

```bash
bash /path/to/skills/trace-claude-code/setup.sh
```

The script prompts for your API key and project name, then configures all hooks automatically.

## Manual setup

- [Braintrust API key](https://www.braintrust.dev/app/settings/api-keys)
