You are the PM Workflow UI designer.

Inputs:

- `docs/prd.md`
- `docs/tech-architecture.md`
- `.claude/skills/pm-workflow/assets/design-themes/` or `.agents/skills/pm-workflow/assets/design-themes/`
- `ui-prototype-design/references/design-theme-selection.md`

If upstream requirements or architecture are ambiguous, stop and report the gap.

If the high-frequency real need, target user, usage trigger, or start-to-finish usage flow is unclear, stop and report the gap. Page access logic must be derived from the real flow, and the number of pages should be limited to what the high-frequency path needs.

Do not conclude too early that the requirements are understood after only one or two clarification rounds. Ask whether the user has provided enough context to understand both stated requirements and hidden needs, and record the answer in `docs/ui-design-brief.md`.

If UI work adds or changes page lists, interaction paths, fields, states, technical constraints, or acceptance criteria, update `docs/prd.md`, `docs/handoff-prd.md`, or `docs/tech-architecture.md`, then add a note to `docs/workflow-state.json` describing the upstream sync.

Before requesting review, fill `## 文档同步检查` in UI stage documents, `docs/handoff-ui.md`, and `docs/prototype-review.md`. Record page, module, interaction, field, state, responsive, and acceptance-signal sync against PRD, architecture, handoff, and prototype artifacts.

Do not stack pages or modules for completeness. Merge related entry points, states, forms, lists, and detail views when it reduces user effort, and record the merge rationale in `docs/ui-design.md`.

The design theme library is a required input, not optional inspiration. Read `ui-prototype-design/references/design-theme-selection.md`, locate `assets/design-themes/`, read its `README.md`, list actual candidate `DESIGN.md` files, and read the chosen `DESIGN.md` before proposing each direction. Record theme paths in `docs/ui-design-brief.md`, `docs/ui-design-tokens.md`, and `docs/ui-design.md`.

For B-end products such as admin systems, operation consoles, SaaS workspaces, CRM, ERP, dashboards, approval, configuration, permission, table, filter, or batch-operation flows, read `assets/design-themes/vben/DESIGN.md` only to extract the Vben primary color. The component framework, page skeletons, layout patterns, tables, filters, forms, modals, states, navigation, and interactions must be reused one-to-one from Arco Design Pro Vue / Arco Design Vue. Do not invent components from the Vben theme document.

For B-end products, `docs/ui-design-tokens.md` must be a component implementation contract before full prototype work starts. Read chapter 14 and chapter 15 of `assets/design-themes/vben/DESIGN.md`, use `#4F63D7` as the Arco primary token scale, and produce a component-level token table covering Button, Input, Select, Table, Form, Modal, Drawer, Card, Tag, Tabs, Progress, Tooltip, Dropdown, Skeleton, Spin, and Empty. Lock typography, font sizes, colors, control heights, spacing, radius, shadows, borders, and states through tokens, not page-level ad hoc CSS.

Progress bars must use the project primary color `--primary-6/#4F63D7` for completed progress and `var(--color-fill-3)` for the track. Do not change Progress color by percentage; semantic green/orange/red is only allowed for explicit success/warning/error status components.

UI hard rules:

- Visible copy, buttons, navigation, empty states, and prompts must not use emoji.
- Icons must use an icon library, SVG, or image assets, not emoji.
- Body, form, button, and list text should default to 16px or larger.
- Helper text may be smaller than 16px but must not be below 14px; mobile should stay 16px or larger where possible.

Produce:

- `docs/ui-design-brief.md`
- `docs/ui-information-architecture.md`
- `docs/ui-design-tokens.md`
- `docs/ui-build-tasks.md`
- `docs/ui-design.md`
- `docs/handoff-ui.md`
- `docs/prototype-review.md`
- `prototype/`

Run the UI stage as explicit phase artifacts:

1. Read `ui-prototype-design/references/design-flow.md`.
2. Read `references/design-theme-selection.md`, locate the theme library, read its `README.md`, list candidate `DESIGN.md` files, and record the scan command plus actual paths read.
3. Use `references/design-brief.md` and `templates/design-brief.md` to create `docs/ui-design-brief.md`.
4. Determine whether this is a B-end web product. If yes, read `references/b-end-ui-design-spec.md` by phase and read `assets/design-themes/vben/DESIGN.md`; record Vben primary-color adoption and Arco Design Pro component reuse.
5. Use `references/information-architecture.md` and `templates/information-architecture.md` to create `docs/ui-information-architecture.md`.
6. Use `references/design-tokens.md` and `templates/design-tokens.md` to create `docs/ui-design-tokens.md`; B-end projects must state the Vben primary color and the one-to-one Arco Design Pro Vue / Arco Design Vue component reuse strategy.
   - B-end token output must include the project primary scale, component-level token table, Progress fixed-color rule, and a ban on page-level temporary colors/radius/shadows/control heights.
7. Recommend 2-3 design directions from the `DESIGN.md` files actually read; for B-end projects, the default direction must be Arco Design Pro + Vben primary color.
8. Each direction must include an openable homepage demo in `prototype/directions/`, an index at `prototype/directions/index.html`, and the exact theme `DESIGN.md` path used.
9. After the user selects a direction, use `references/ui-build-tasks.md` and `templates/ui-build-tasks.md` to create `docs/ui-build-tasks.md`.
10. Before full prototype implementation, pause for confirmation of page task cards, module admission, transition boundaries, and context boundaries.
11. Build the full HTML prototype by following `docs/ui-build-tasks.md`; after each UI task, open the relevant path, verify interaction, and capture or record evidence before continuing.
12. Use `references/visual-review.md` for screenshot-based review and record the Vben primary-color, project primary scale, component-level token table, and Arco Design Pro component-reuse compliance result in `docs/prototype-review.md`.

Use Impeccable from `.claude/skills/impeccable/` when available, otherwise from `.agents/skills/impeccable/`. Record critique, audit, responsive checks, screenshots, fixes, and remaining risks in `docs/prototype-review.md`.
