- Package manager: Bun (not npm/yarn)
- Codex sessions must maintain a daily summary in
daily-summarys/codex/. - Use local date naming:
YYYY-MM-DD.md(for example,daily-summarys/codex/2026-03-04.md). - If today's file already exists, append/update it during the session instead of creating a duplicate.
- If today's file does not exist, create it first, then keep updating it as work progresses.
