## 🚀 Next Session: PMAT-070-003

### Why Continue or Fresh Session?

**Option 1: Continue Current Session** (Recommended if token budget allows)
- Have 95K tokens remaining
- Phase 3 estimated ~3.5 hours
- Can complete in current session
- Maintains momentum

**Option 2: Start Fresh Session** (Recommended if prefer clean slate)
- Full 200K tokens for Phase 3
- Clean mental model
- Phase 2 complete and documented

### Quick Start Commands

```bash
cd /home/noah/src/paiml-mcp-agent-toolkit

# Read kickoff guide
cat docs/sprints/SPRINT-70-PHASE3-KICKOFF.md

# Start RED phase
touch server/tests/mutate_command_tests.rs
touch server/src/cli/handlers/mutate_command_handler.rs
```

### What to Say

Just type:
```
continue (next, recommended best step or new roadmap task)
```

### Expected Flow

1. ✅ Read SPRINT-70-PHASE3-KICKOFF.md
2. ✅ Create RED phase tests (10 tests)
3. ✅ Add Mutate variant to Commands enum
4. ✅ Verify tests fail
5. ✅ Commit RED phase
6. ✅ Implement GREEN phase (command handler)
7. ✅ Verify tests pass
8. ✅ REFACTOR phase
9. ✅ VERIFY phase
10. ✅ Final commit

**Estimated Time**: ~3.5 hours
