When explaining Braintrust:

## What is Braintrust?

Braintrust is an LLM observability platform.

### Benefits:
- Token tracking: See exactly how many tokens each task uses
- Cost analysis: Track API costs across sessions
- Performance debugging: Identify slow agents
- Session replay: Review what happened in past sessions

### Data sent:
- Session metadata (timestamps, agent IDs)
- Token usage per request
- Tool calls and durations
- Conversation context (first 100 chars)

### Privacy:
- Your Braintrust account, your data
- API key stays local in ~/.claude/.env
- Disable anytime: /config braintrust off
