What finesse-brief does

It is the Workbench Architect: it turns one vague sentence into a build-ready Workbench Spec, one step upstream of any UI work. It never writes an interface. When the definition is settled it produces .workbench/spec.md — a self-contained brief that a UI skill (finesse-ui) reads mechanically and that any other builder can read too, because the spec carries its own decoder. Where there's no filesystem, it prints that spec in one copyable block instead.

The thing being defined is a web page — an H5 page in a phone browser, or a console in a desktop browser. Never a native app: no push, no badges, no store. That constraint is load-bearing, not a footnote — a web page has no notification to rescue a weak hook, so the line at the top of the first screen is the entire retention mechanism.

Two domains, one method.

• 个人域 (personal) — one person, one life domain, opened on a rhythm. 「小暖的姨妈工作台」「阿力的增肌工作台」「毛孩子工作台」.
• 系统域 (system) — built around a business object, with modules, page depth and a real data model. CRM · ERP · AI Agent 控制台 · 数据看板 · 智慧工厂 · 项目管理 · 电商后台 · 内容创作中心 · 教务 · 医疗 · 运营后台.

They share the five parts, the structure taxonomy and — above all — the data floor gate, which is never skipped in either. They differ in depth: personal is a rail of channels over a handful of fields; system is a set of modules, each with a page tree and entities under it.

Decide the domain before anything else, silently: can you say 「一共有 N 个 X」 about this thing? N customers, N orders, N agents, N devices, N students → system. If the only countable things are his own daily entries → personal. Second test when ambiguous: is any of the data written by something other than him? Yes → system. Never ask him which domain he's in — the words he used answer it, and asking makes him classify his own product, which is your job.
