What problem does it solve? Turning an approved design into working code often drifts into ad-hoc edits, skipped tests, and lost context. This Skill converts an approved design or requirements into a structured, file-level implementation plan and executes it with disciplined TDD, task tracking, and verification gates. ## Core Features & Use Cases - Structured Planning: Decomposes work into bite-sized tasks with exact file paths, tracer-bullet first slices, and explicit batch dependencies. - TDD Execution Rhythm: Defaults every task to red-green-refactor, with explicit exceptions for config, migrations, and docs. - Parallel Batch Dispatch: Groups independent tasks and dispatches subagents with workspace isolation, placement protocols, and clean committed handoffs. - Checkpoint & Resume: Writes human-readable checkpoint artifacts and latest-pointer state so work can resume after a context reset. - Use Case: After a design doc is approved for a new API feature, invoke this Skill to produce a task plan, track each task in the host's todo system, implement with TDD, and verify the full suite before handoff. ## Quick Start Ask the agent to implement the approved design for the current ticket using the implement skill and follow the plan with TDD.
