What problem does it solve? Turning a feature idea, bug report, or requirements document into an actionable implementation plan is time-consuming and error-prone. This Skill produces durable, repo-grounded plans with clear scope, decisions, file paths, and test scenarios so implementation can start confidently. ## Core Features & Use Cases - Structured Plan Generation: Builds plans with problem frame, requirements traceability, key technical decisions, implementation units, risks, and test scenarios, saved to docs/plans/ with a conventional filename. - Research-Driven Planning: Dispatches parallel research agents covering repo patterns, institutional learnings, framework docs, and best practices before structuring the plan. - Plan Deepening: Runs a confidence-gap check on existing plans and strengthens weak sections via targeted sub-agent review with interactive accept/reject control. - Use Case: After brainstorming a new checkout feature, invoke the Skill to produce a sequenced implementation plan with per-unit test scenarios, then hand off directly to execution or create a tracked issue. ## Quick Start Ask the assistant to create a plan for your feature or task, for example: plan how we should build user authentication with OAuth support.
