| Trigger | Action |
|---|---|
| Before first delegation | After decomposition, before agents start |
| After each phase | When a parallel batch completes |
| Before risky work | DB migrations, large refactors, security changes |
| Session end | Any session with incomplete work |
| Context running low | Checkpoint immediately |
