handoff-to-brief
适合重构或继承旧产品时快速产出可执行 brief
将现有产品的设计/交接文档转成合规的屏幕 brief，跳过发现阶段
把现有产品的设计或交接文档直接拆成可交付的 screens-brief.md，用来跳过探索阶段，快速产出每个屏幕的目的、必展项、交互动作与状态、文案和设计系统指向。适合手头有老 PRD、线上应用反推说明或设计系统导出清单，需要把零散资料整理成合规交付件时使用。特别之处是从源文档抽取信息并标注那些文档没决定的关卡（冲突、孤立范围、哪些屏在 v0 发、哪些延后），不用逐字段面访。

Turn an EXISTING product's design/handoff documentation — a reverse-engineered spec of a live app, an old PRD, a design-system export doc with a screen inventory — directly into a conformant screens-brief.md, skipping the discovery stages (run, agent-domain-spec, grill-to-brief) that exist to validate a NEW, undecided idea. Extracts each screen's purpose/must-show/actions+outcomes/states/copy and the design-system pointer straight from the source doc instead of interviewing field-by-field, but still surfaces and confirms every genuine gate decision the doc leaves open (⚠-flagged inconsistencies, live-vs-dead/orphaned scope, which screens ship in v0 vs defer, which file(s) hold the design tokens) rather than silently resolving them. Writes doc/ws-<slug>/screens-brief.md in the exact heading contract grill-to-brief produces, so /usecase-factory:design-a-screen (optional) and /usecase-factory:brief-to-html run unmodified afterward. Use when the user already has documentation of something

This skill is a **thin router**. All execution logic lives in `playbook.md` next to this file (kept separate so it can be versioned without touching the trigger contract).

`handoff-to-brief` is an **alternate entry point**, not a stage inside the research pipeline. Use it INSTEAD of `run` → `agent-do
