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.
