PLAN, REVIEW, and SCAN refuse non-read-only tools. FIX allows writes but no shell. BUILD and SWE allow everything. Toggle with Ctrl+M or /mode.
| Mode | File edits | Shell | Use for |
|---|---|---|---|
| BUILD | Yes | Yes | Actually making changes |
| PLAN | No | No | Questions, review, exploration |
| REVIEW | No | No | Diff review with focused prompt |
| SCAN | No | No | Security scanning |
| FIX | Yes | No | Safe auto-fix without shell access |
| SWE | Yes | Yes | Reproduce-first fixes, 60-iteration budget |
