What problem does it solve? Projects accumulate documentation inconsistently: briefs get lost, requirements and design docs mix together, and doc-comment baselines quietly erode when CI checks are removed. This Skill standardizes how project documentation is written, organized, and maintained so every artifact stays auditable and doc comments keep building clean. ## Core Features & Use Cases - Docs Taxonomy: Derives a PRD from the brief at docs/brief.md, then a PCD, then an implementation plan, each stored as a dated YYYY-MM-DD-<feature>-<type>.md file under docs/prds/, docs/pcds/, or docs/plans/. - Documentation Baseline Guidance: Enforces the rule that every declaration above private carries a doc comment and the docs build resolves, with per-stack toolchains (SwiftLint missing_docs, TypeDoc validation, deno doc --lint). - Docs Publisher Retirement: Explains how to safely fix documentation checks or retire unshipped docs publishing scripts by grepping for live callers before deleting anything. - Use Case: When starting a new feature, ask the AI to draft the PRD from your brief, then generate the PCD and a bite-sized implementation plan, each in its correctly named dated file. ## Quick Start Write a PRD for the new onboarding feature derived from docs/brief.md and save it as a dated file in docs/prds/.
