Process

Read recent trace files: ls -t ~/.claude/traces/*.jsonl | head -5 to find the 5 most recent sessions

Parse JSONL entries: Each line is a JSON object with type, timestamp, and type-specific fields

Analyze patterns:

Repeated failures: Commands that fail (exit_code != 0) repeatedly across sessions
File hotspots: Files modified most frequently — candidates for refactoring or testing
Wasted turns: Commands that produce no useful output or always error
Session health: Error rate per session, trend over time

Report findings: Actionable insights, not raw data

Output Format

## Trace Review (last N sessions) ### Recurring Failures - [pattern]: happened N times across M sessions ### File Hotspots - [file]: modified N times (consider: tests? refactor? stability?) ### Session Health Trend - Avg error rate: N% - Avg commands/session: N - Trend: improving/stable/degrading ### Recommendations - [actionable suggestion based on patterns]
