Index all sessions (incremental - only new/changed files)

uv run ~/.claude/skills/extract-transcripts/transcript_index.py index

Force full reindex

uv run ~/.claude/skills/extract-transcripts/transcript_index.py index --full

Limit number of files to process

uv run ~/.claude/skills/extract-transcripts/transcript_index.py index --limit 10

List recent sessions

uv run ~/.claude/skills/extract-transcripts/transcript_index.py recent uv run ~/.claude/skills/extract-transcripts/transcript_index.py recent --limit 20 uv run ~/.claude/skills/extract-transcripts/transcript_index.py recent --project myapp uv run ~/.claude/skills/extract-transcripts/transcript_index.py recent --since 7d

Search across sessions

uv run ~/.claude/skills/extract-transcripts/transcript_index.py search "error handling" uv run ~/.claude/skills/extract-transcripts/transcript_index.py search "query" --cwd ~/myproject
