Codex Chat Export

Codex Chat Export

Overview

This skill turns local Codex Desktop conversation data into readable transcript exports. It is built for backup, knowledge capture, publishing, and thread migration workflows.

When To Use

Use this skill when the user asks to:

• export Codex chat history
• back up one conversation or all conversations
• find a thread by title and save it as Markdown
• convert rollout JSONL files into readable transcripts
• archive useful Codex sessions into JSON for further processing

Workflow

1. Confirm the target scope. Single thread: use list first, then export --id or export --contains. Latest thread: use export --latest. Batch export: use export --all --output <dir>.
2. Run the bundled script: python3 scripts/export_codex_chat.py ...
3. Prefer Markdown for readable archives and JSON for automation pipelines.
4. Add --include-tools only when tool traces are useful.
5. For cleaner exports, leave environment stripping on unless the user explicitly wants raw input context.

Commands

List recent threads:

codex-chat-export list

List as JSON:

codex-chat-export list --json

Export the latest thread as Markdown to stdout:

codex-chat-export export --latest --format markdown

Export a matching thread into a directory:

codex-chat-export export --contains 复盘 --format markdown --output exports/

Export one thread with tool traces:

codex-chat-export export --id <thread-id> --include-tools --output thread.md

Notes

• Thread discovery uses ~/.codex/state_5.sqlite.
• Transcript content comes from ~/.codex/sessions/**/rollout-*.jsonl.
• Encrypted reasoning is intentionally skipped.
• Duplicate telemetry events are skipped to keep exports clean.
