description: Thin vertical slices — implement, test, verify, commit. Use for /build. Supports /build auto after plan approval.

Overview
One slice at a time. Feature flags and safe defaults when appropriate.
Modes
| Mode |
Trigger |
Behavior |
| Slice |
/build or "implement next task" |
One approved task from plan; test + commit |
| Auto |
/build auto or "build auto" |
Run all plan tasks sequentially; pause on failure or risky step; commit per task |
Process (slice)
- Confirm which task (from plan or user).
- Implement smallest complete slice.
- Run tests; fix until green.
- Commit with scoped message.
- Report done-when evidence; ask to continue or stop.
Process (auto)
- Load approved task list (plan or spec-outline).
- For each task: implement → test → commit → brief status.
- Pause on: test failure, security-sensitive change, ambiguous scope, user interrupt.
- Do not skip verification between tasks.
Rationalizations
| Excuse |
Reality |
| "Batch whole feature" |
Slices reduce blast radius. |
| "Tests after all tasks" |
Each slice needs proof before next. |
