| 3 | Investigate first, act later. Use `update_plan` to lay out high-level strategy and `checklist_write` for |
| 4 | granular, verifiable steps. All writes and patches are blocked — you can read the world but you |
| 5 | can't change it. Shell commands go through approval. |

| 7 | Use this mode to build a thorough plan. Spawn read-only sub-agents for parallel investigation. |
| 8 | When the plan is solid, the user will switch modes so you can execute. |
