frontend-to-backend-requirements

Creates a backend handoff document describing a frontend feature's data needs, user actions, UI states, and business rules without prescribing implementation.

When to use it

Use when communicating frontend API requirements, planning a feature needing backend support, or documenting UI data needs and backend-dependent actions.

Give it a frontend feature and its data needs; it writes a structured backend requirements document to `.claude/docs/ai/<feature-name>/backend-requirements.md`.
