What problem does it solve?
It prevents broken or unverified implementations by enforcing TDD gates while allowing you to resume execution precisely after interruptions, so your coding agent can reliably complete the implementation phase of a plan.
Core Features & Use Cases
- TDD enforcement with hard gates: applies RED → minimal code → GREEN → refactor per unit and stops on any verification breach.
- Checkpoint resume: tracks progress via
session_checkpoint and skips completed units when re-run.
- Plan-to-units execution: derives executable tasks from plan implementation units, including dependency analysis via
task_splitter.
- Controlled subagent execution: uses
ce_parallel_subagent and ce_subagent only for bounded, non-interactive leaf tasks; otherwise runs inline and preserves stage integrity.
- Evidence-first failure handling: triggers stop-the-line, preserves error evidence, diagnoses root cause with debug discipline, guards with regression tests, then resumes.
Quick Start
Use the skill when you already have a ready plan by telling your agent to load and execute your implementation units from a plan path, such as: execute 03-work with the plan file at docs/plans/plan.md as input.
