## Description

AI DevKit · Implementation phase guidance for executing feature plans and checking implementation against design. Use when the user wants to implement planned tasks, update implementation docs, verify code matches design, or run dev-lifecycle phases 5 and 7.

# Dev Implementation

Run implementation work for configured AI docs features. Before changing docs or code, propose the concrete plan for this phase and wait for user approval unless the user already approved the exact phase plan.

## Phase Contract

1. Run `npx ai-devkit@latest lint` before phase work.
2. If working on a named feature, run `npx ai-devkit@latest lint --feature <name>`.
3. Read requirements, design, planning, implementation, and testing docs before changes.
4. Use the `tdd` skill while executing implementation tasks: write a failing test before production code, then make it pass.
5. Apply the `verify` skill before completing tasks or making implementation alignment claims.
6. Keep testing and implementation docs in lockstep with code. Do not defer all doc updates to final verification.
7. If parent `dev-lifecycle` established usable task tracing, emit phase, progress, next-step, blocker, and evidence events per `task`.

## Execute Plan

Use for Phase 5.
