# A fast-track change

> Small changes with a feature file, evidence, and the living spec kept true.

Example: *"Rename the Sign out button on the home page to Log out."*

1. **Lane check** — ≤ 3 files, no schema, permission or money change. Otherwise the agent says so and uses the spec lane.
2. **Feature file** — `agent-kit work new feature rename-logout` creates `work/features/NNN-rename-logout.md` with the goal and tasks (skipped for a one-line edit).
3. **Do the work** — logic changes go test-first in SDD + TDD.
4. **Keep the living spec true** — if a living spec describes this behaviour (`home.R1 — Sign out`), the agent edits the requirement or scenario in place, runs `agent-kit specs lint home` and `agent-kit qa sync`. A new requirement or capability isn't fast-track.
5. **Evidence and finish** — each task ticked with the check run; project checks; `status: done`.
