spec-writer
An expert-guided skill for creating layered software specification documents for greenfield projects. Produces five document types: Vision, Business Requirements (BRS), Software Requirements (SRS), Architecture & Design, and Behavioral Spec & Test Verification. Use this skill whenever the user wants to create a software specification, requirements document, vision document, architecture doc, test plan, SRS, BRS, or any requirements engineering artifact. Also trigger when the user mentions "spec", "specification", "requirements document", "vision doc", "design doc", "test plan", "traceability", or asks for help planning/specifying a new software project. Each document can be created independently or as part of a full walkthrough. The skill drives the conversation through clarifying questions, provides expert suggestions based on project context, and outputs polished markdown documents.
