Export

Export

Purpose

Export a Codex session JSONL file from ~/.codex/sessions or ~/.codex/archived_sessions into a readable Markdown transcript.

Runtime Requirement

• Requires python3 with Python 3.10 or newer.

Default Workflow

1. Run the exporter from the active workspace:

if [ -n "${CODEX_EXPORT_SKILL_DIR:-}" ]; then
  EXPORT_SKILL_DIR="$CODEX_EXPORT_SKILL_DIR"
elif [ -f "$HOME/.codex/skills/export/scripts/export_codex_session.py" ]; then
  EXPORT_SKILL_DIR="$HOME/.codex/skills/export"
else
  EXPORT_SKILL_DIR="$HOME/.agents/skills/export"
fi
python3 "$EXPORT_SKILL_DIR/scripts/export_codex_session.py" --json --output-dir "$(pwd)/codex-session-exports"

2. Parse the JSON result and treat file, session_id, message_count, include_tools, and selected_by as the result.
3. Reply with the absolute Markdown file path and a short export summary.

Selection Rules

• Default selection is the current Codex conversation id from CODEX_THREAD_ID or CODEX_SESSION_ID when Codex exposes it to the tool process.
• If no current conversation id is available, select the most recently modified Codex session whose session metadata cwd matches the current working directory.
• If no session id or cwd match is available, fall back to the most recent Codex session globally.
• If the user provides a session id, run with --session-id <id>.
• If the user provides a JSONL path, run with --session-file <path>.

Content Rules

• Default export includes visible user messages and visible assistant messages.
• Do not paste the full exported transcript into chat unless the user explicitly asks.
• Do not expose system prompts, developer instructions, AGENTS context injection, Codex Skill context injection such as <skill>...</skill>, environment context injection, or encrypted reasoning. The exporter skips these records.
• Tool calls and command outputs are excluded by default. If the user asks for command logs or full execution trace, add --include-tools.
• Local source file paths and cwd metadata are redacted in the Markdown by default. Add --show-paths only when the user explicitly asks for full local source paths.
• Run the exporter as the final substantive action. The short response that reports the exported file path will only appear in a later export.

Useful Commands

List recent sessions:

if [ -n "${CODEX_EXPORT_SKILL_DIR:-}" ]; then
  EXPORT_SKILL_DIR="$CODEX_EXPORT_SKILL_DIR"
elif [ -f "$HOME/.codex/skills/export/scripts/export_codex_session.py" ]; then
  EXPORT_SKILL_DIR="$HOME/.codex/skills/export"
else
  EXPORT_SKILL_DIR="$HOME/.agents/skills/export"
fi
python3 "$EXPORT_SKILL_DIR/scripts/export_codex_session.py" --json --list

Export a specific session:

if [ -n "${CODEX_EXPORT_SKILL_DIR:-}" ]; then
  EXPORT_SKILL_DIR="$CODEX_EXPORT_SKILL_DIR"
elif [ -f "$HOME/.codex/skills/export/scripts/export_codex_session.py" ]; then
  EXPORT_SKILL_DIR="$HOME/.codex/skills/export"
else
  EXPORT_SKILL_DIR="$HOME/.agents/skills/export"
fi
python3 "$EXPORT_SKILL_DIR/scripts/export_codex_session.py" --json --session-id <session-id> --output-dir "$(pwd)/codex-session-exports"

Export with tool logs:

if [ -n "${CODEX_EXPORT_SKILL_DIR:-}" ]; then
  EXPORT_SKILL_DIR="$CODEX_EXPORT_SKILL_DIR"
elif [ -f "$HOME/.codex/skills/export/scripts/export_codex_session.py" ]; then
  EXPORT_SKILL_DIR="$HOME/.codex/skills/export"
else
  EXPORT_SKILL_DIR="$HOME/.agents/skills/export"
fi
python3 "$EXPORT_SKILL_DIR/scripts/export_codex_session.py" --json --include-tools --output-dir "$(pwd)/codex-session-exports"
