What problem does it solve? It turns a confirmed requirement into a concrete, evidence-based development plan before any code is written, preventing architecture conflicts, missed cross-layer impacts, and unverifiable deliverables. ## Core Features & Use Cases - Automatic requirement clarification: Runs the grill-me flow first to produce a requirement confirmation sheet, or skips it when requirements are already explicit. - Feasibility and impact scanning: Verifies the plan against existing code and docs using ripgrep, then walks a layer-by-layer checklist covering parsing, models, APIs, frontend locales, exports, tests, docs, and build/deploy. - Structured plan output: Writes a step-by-step development plan with file lists, verification methods, a not-to-do list, acceptance criteria, and open questions into docs/current-plan.md. - Use Case: Before adding a new replay statistic to the WoTB Tools project, invoke this Skill to confirm the requirement, check contract impact across backend and frontend, and produce an approved plan ready for implementation. ## Quick Start Ask the assistant to run plan-designer to design a development plan for your feature before any coding begins.
