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)
