Use when a requirement or an unproven technique must be made clickable before it is built — produces a single self-contained HTML prototype that doubles as a design spike, whose control panel is the open questions. Rebuilds existing screens at high fidelity from real source (structure, copy strings, icons, tokens, each cited file:line; invents only what the requirement adds), derives one control per acceptance criterion or technical unknown, drives real data through a dev-server proxy that also proposes the route shape (live > capture > labeled stub, never invented), verifies every state in a real browser, and reports what the spike settled. Triggers on 'prototype FR-NNN', 'clickable prototype of FR-NNN', 'make this requirement clickable', 'spike this technique'. NOT for inventing UI from a prompt — use a generative-design skill. NOT for production frontend code. NOT the client-confirmation record — that is a spec-playback step. NOT an ADR writer.
