Cs Feat Design

This drafts design documents for new features in Chinese development workflows, specifically targeting the design phase before implementation. It enforces a strict "current state → changes" structure covering both your domain model (nouns, types, contracts) and orchestration layer (workflows, control flow). The skill stops you from making decisions the user hasn't explicitly confirmed, forces you to write testable acceptance criteria instead of vague goals, and includes a mandatory section on structural health that evaluates whether files are too fat or directories too crowded before you add more code. It generates a YAML checklist from the approved design and integrates with roadmap items. Useful if you want design docs that actually constrain implementation rather than just describe intent.
