機能仕様策定

To turn vague requirements into structured feature specifications, provide your initial ideas to trigger an interactive elicitation process that captures feature names, purpose, users, scope, and entities to generate comprehensive plan documents.

Creating feature specs generates six markdown files under docs/plan/<feature>/: 00_OVERVIEW.md, 01_DOMAIN_MODEL.md, 02_DATA_ACCESS.md, 03_USECASE.md, 04_API_INTERFACE.md, and 05_FRONTEND.md for cross-functional planning.

The domain modeling process handles unresolved items by marking them with TBD markers throughout the generated specification files, ensuring unresolved prerequisites, entities, or API interfaces are clearly flagged for later clarification.

Yes, you can generate both API interface and frontend UI documentation from a single feature scope. The elicitation process captures use cases and entities, then produces 04_API_INTERFACE.md and 05_FRONTEND.md to align backend and frontend domains.

The best way to document use cases and data access is through structured specification generation, which produces 03_USECASE.md and 02_DATA_ACCESS.md files aligned with domain-modeling guidelines to clarify cross-functional team workflows.

No, you do not need fully detailed requirements to start generating feature specification documents. You can provide vague initial ideas, and the interactive elicitation process will capture key attributes to structure the planning files.
