Session Activities

1. Codebase Analysis - Used codebase-analyzer skill to generate repository structure diagram
2. Cleanup Operations - Removed untracked backup file and scattered .claude/ directories
3. Telemetry Verification - Confirmed OpenTelemetry data capture to local and remote storage

Files Modified (Untracked)

• assets/js/scripts.min.js.bak - Removed (backup file)
• _includes/.claude/ - Removed (settings consolidation)
• _reports/.claude/ - Removed (settings consolidation)
• _posts/.claude/ - Removed (settings consolidation)
• utils/.claude/ - Removed (settings consolidation)
• docs/.claude/ - Removed (settings consolidation)
• docs/schema/.claude/ - Removed (settings consolidation)

Recommendations

1. Investigate slow stop-tsc-check - 3533ms execution time warrants investigation
2. Monitor context utilization - Currently at 23.2%, well within healthy range
3. Consider archiving old traces - Local telemetry files growing (~1.2MB/day)
