# Extract Transcripts
Extracts readable markdown transcripts from Claude Code and Codex CLI session JSONL files.
## Scripts
### Claude Code Sessions
```bash
# Extract a single session
python3 ~/.claude/skills/extract-transcripts/extract_transcript.py <session.jsonl>
# With tool calls and thinking blocks
python3 ~/.claude/skills/extract-transcripts/extract_transcript.py <session.jsonl> --include-tools --include-thinking
# Extract all sessions from a directory
python3 ~/.claude/skills/extract-transcripts/extract_transcript.py <directory> --all
# Output to file
python3 ~/.claude/skills/extract-transcripts/extract_transcript.py <session.jsonl> -o output.md
# Summary only (quick overview)
python3 ~/.claude/skills/extract-transcripts/extract_transcript.py <session.jsonl> --summary
# Skip empty/warmup-only sessions
python3 ~/.claude/skills/extract-transcripts/extract_transcript.py <directory> --all --skip-empty
```
**Options:**
- `--include-tools`: Include tool calls and results
- `--include-thinking`: Include Claude's thinking blocks
- `--all`: Process all .jsonl files in directory
- `-o, --output`: Output file path (default: stdout)
- `--summary`: Only output brief summary
- `--skip-empty`: Skip empty and warmup-only sessions
- `--min-messages N`: Minimum messages for --skip-empty (default: 2)
### Codex CLI Sessions
```bash
# Extract a Codex session
python3 ~/.claude/skills/extract-transcripts/extract_codex_transcript.py <session.jsonl>
# Extract from Codex history file
python3 ~/.claude/skills/extract-transcripts/extract_codex_transcript.py ~/.codex/history.jsonl --history
```
## Session File Locations
### Claude Code
- Sessions: `~/.claude/projects/<project-path>/<session-id>.jsonl`
### Codex CLI
- Sessions: `~/.codex/sessions/<session_id>/rollout.jsonl`
- History: `~/.codex/history.jsonl`
## DuckDB-Based Transcript Index
For querying across many sessions, use the DuckDB-based indexer:
```bash
# Index all sessions (incremental - only new/changed files)
python3 ~/.claude/skills/extract-transcripts/transcript_index.py index
# Force full reindex
python3 ~/.claude/skills/extract-transcripts/transcript_index.py index --full
# Limit number of files to process
python3 ~/.claude/skills/extract-transcripts/transcript_index.py index --limit 10
# List recent sessions
python3 ~/.claude/skills/extract-transcripts/transcript_index.py recent
python3 ~/.claude/skills/extract-transcripts/transcript_index.py recent --limit 20
python3 ~/.claude/skills/extract-transcripts/transcript_index.py recent --project myapp
python3 ~/.claude/skills/extract-transcripts/transcript_index.py recent --since 7d
# Search across sessions
python3 ~/.claude/skills/extract-transcripts/transcript_index.py search "error handling"
python3 ~/.claude/skills/extract-transcripts/transcript_index.py search "query" --cwd ~/myproject
# Show a session transcript
python3 ~/.claude/skills/extract-transcripts/transcript_index.py show <file_path>
python3 ~/.claude/skills/extract-transcripts/transcript_index.py show <file_path> --summary
```
**Requirements:** DuckDB (`pip install duckdb`)
**Database location:** `~/.claude/transcript-index/sessions.duckdb`
## Output Format
Transcripts are formatted as markdown with:
- Session metadata (date, duration, model, working directory, git branch)
- User messages prefixed with `## User`
- Assistant responses prefixed with `## Assistant`
- Tool calls in code blocks (if --include-tools)
- Thinking in blockquotes (if --include-thinking)
- Tool usage summary for Codex sessions
