Codex Session to Markdown

Convert a Codex CLI session JSONL transcript to a readable markdown file.

Session ID

User provided: $ARGUMENTS

Steps

1. If no session ID provided, list recent sessions:

   python ./codex_session_to_md.py --list -n 20
   

   Show the list and ask the user which session to convert.

2. Find and convert the session:

   python ./codex_session_to_md.py "$ARGUMENTS"
   

   • If multiple matches, show them and ask user to be more specific.
   • If no matches, suggest --list to browse available sessions.

3. Read and summarize the output markdown file. Show:

   • Session metadata (cwd, timestamp, model)
   • Number of messages
   • A brief summary of what the conversation covered (first few user messages)

4. Offer to show the full transcript if the user wants to read it.

Notes

• Session files are stored at ~/.codex/sessions/YYYY/MM/DD/rollout-*.jsonl
• The UUID in the filename is the session ID
• Partial UUIDs work (e.g. 019e6829 matches 019e6829-4f2b-7de1-b9f7-ee507b5e5e59)
• Output defaults to ./<session-uuid>.md in the current directory
• Use -o <path> to specify a custom output path
