What problem does it solve? Turning a feature idea, requirements document, or vague goal into an actionable plan requires research, scoping, and sequencing that is easy to get wrong. This Skill produces durable, repo-grounded implementation plans with traced requirements, ordered implementation units, and explicit test scenarios. ## Core Features & Use Cases - Structured Plan Generation: Breaks work into dependency-ordered implementation units with stable U-IDs, repo-relative file paths, and enumerated test scenarios. - Research-Driven Planning: Dispatches parallel research agents for codebase patterns, institutional learnings, framework docs, and best practices before structuring the plan. - Plan Deepening: Runs a confidence-gap scoring pass on existing plans and strengthens weak sections via targeted sub-agent research with interactive review. - Universal Planning: Routes non-software tasks (trips, study plans, events) to a domain-agnostic workflow with curated options and research. - Use Case: After brainstorming a new authentication feature, invoke this Skill to produce a dated plan file in docs/plans/ with requirements traceability, key technical decisions, and per-unit test scenarios ready for execution. ## Quick Start Ask the agent to create a plan for your feature by saying "plan the user authentication flow" and it will research the codebase and write a structured plan document.
