Another important thing to do is to instruct the agent to keep a <plan-name>-NOTES.md file where it tracks its progress and keeps implementation notes. The notes are usually short with Opus 4.5 but very helpful, especially when you need to reset mid-phase and restart it with a fresh context.

If you keep the notes around in repo, you can instruct future plan writers to review implementation notes from relevant plans to keep continuity.
