Session Activities

Codebase Analysis - Used codebase-analyzer skill to generate repository structure diagram
Cleanup Operations - Removed untracked backup file and scattered .claude/ directories
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

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