feature-writer skillA

feature-writer is agent-read markdown (skill) from sean-m-cooper/ai_tools: Guide a product owner through defining a feature — UI, backend, or full-stack. Conducts a structured interview that branches based on feature type, then produces a structured Feature document. Use when a PO wants to define a new feature, plan a screen flow, document an API, or describe a backend capability. Examples: "let's define a new feature", "I want to plan a UI flow", "help me define an API feature", "plan a backend service", "/feature-writer"..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
