# Detailed Prototypes

> Use when a human-approved design system exists and the in-scope screens need high-fidelity prototypes: one prototype per screen, each tracing to a functional requirement, user story, or acceptance criterion, with mock/API-gap annotations for anything designed ahead of its backend contract. This is the detailed_prototypes action of the design stretch — one Agent-tool dispatch with subagent_type ui-ux-developer — UI-bearing targets only, and it hard-requires the recorded human approval visual-design stopped for.

# Detailed Prototypes

Produce high-fidelity prototypes for the approved design system. The precondition is not that visual-design passed — it is that a human approved its output.

## Dispatch

One synchronous `Agent`-tool call, `subagent_type: ui-ux-developer`. Do not dispatch this action at all while visual-design's manual approval is missing — dispatching it anyway is a process defect, not initiative.

## Required inputs

- The human-approved `design-system.md` from visual-design.
- The target's functional-requirement catalog.
- Relevant user-story documents for in-scope actors.
- Relevant business rules referenced by in-scope screens.

## Required outputs (all mandatory)

- High-fidelity prototypes per in-scope screen, each tracing to a functional requirement, user story, or acceptance criterion.
- Mock/API-gap annotations for any screen designed ahead of its backend contract.

## Result

Report each required output produced (with its location), the result (pass / pass_with_risks / blocked / failure), and blocking questions as an explicit list (empty list stated explicitly).
