  • Tokens: Input, output, cache read, cache write, total
  • Cost: Estimated USD based on Claude Sonnet 4.5 pricing

Hook Feedback

The PreToolUse and PostToolUse hooks can provide feedback when they block operations or detect issues:

Security Block: 

🔒 BLOCKED: Access to sensitive file '.env'
   This file matches a security pattern and cannot be accessed.

Cost Warning: 

💰 COST WARNING: Session approaching budget limit
   Tool: WebSearch (expensive operation)

Quality Violation: 

⚠️  Code Quality Warning: src/api.php
   Linter: phpcs
   Line 42: Missing function docblock

Note: SessionStart and SessionEnd hooks log data in the background. Check ~/.claude/session-logs/sessions.csv to view your session history.

Privacy & Security

What's logged:

✅ Session metadata (timestamps, IDs, duration) ✅ Usage statistics (tokens, costs, tool counts) ✅ Session summary (one-line description) ✅ Security events (blocked operations) ✅ Quality events (linter results)

NOT logged:

❌ Actual code or conversation content ❌ Sensitive data or credentials ❌ File contents or API responses

All data stays on your machine unless you explicitly configure Google Sheets sync.
