Codex History
Resume work started in OpenAI Codex CLI by reading its conversation history.
Data Locations
There are two history.jsonl files and, depending on Codex version, session files or SQLite state:
| Source | Path | Content |
|---|---|---|
| Global prompt index | ~/.codex/history.jsonl |
User prompts with session_id links |
| Per-project prompt index | <project-root>/.codex/history.jsonl |
Same format, scoped to one repo |
| Session logs (legacy) | ~/.codex/sessions/YYYY/MM/DD/rollout-<timestamp>-<uuid>.jsonl |
Full conversations |
| SQLite state | ~/.codex/state_5.sqlite |
Newer storage, may contain thread data |
Session files may not exist in newer versions, so prefer history.jsonl first and treat session JSONL as an optional richer source.
