What problem does it solve? Writing a design doc that survives review is hard: authors skip sections, propose a single solution without alternatives, or advance before goals are validated. This Skill walks you through authoring a design doc one section at a time, gating each phase against the plumbeer-design-reviewer checklist so the finished document is review-ready by construction. ## Core Features & Use Cases - Section-by-section authoring: Builds the doc from a bundled markdown template covering Problem, Challenges, Goals, Strategy, Cost, API, Risks, Schedule, and more. - Checklist-driven gating: Invokes the plumbeer-design-reviewer skill after each section and loops on Partial or Not Met rows until they pass, with explicit user confirmation required for process gates like ally reviews. - Explicit bypass tracking: Skipped gates are recorded visibly in the doc rather than silently omitted, and existing files can be resumed from the first unmet checklist row. - Use Case: You need a high-level design for a new service. The Skill interviews you for the problem and goals, pushes back when you offer only one candidate solution, verifies ally reviews happened, and produces a single markdown file that passes the full 24-row readiness matrix. ## Quick Start Ask the assistant to help you write a design doc for your project from scratch, and it will interview you section by section while gating progress on the design review checklist.
