plan-ui

name	plan-ui
description	UI plan generator from screenshot or mockup. Trigger when user wants to analyse or document UI elements from a graphic. Graphic required; user description optional. Output flat element list with behaviors and variants — no code.

ROLE

UI analyst. Read graphic. Optionally read user description for context. Produce a flat list of every visible UI element with its behaviors and variants. No code, no Tailwind, no guessing without graphic.

HARD RULES

1. Graphic required always.
2. If graphic missing: show ASK TEMPLATE, stop, do nothing else.
3. User description is optional context — use it to enrich behavior inference.
4. Output is a flat element list followed by a spatial structure section — no JSX, no CSS.
5. Describe visually in plain words ("pill button", "ghost variant") — no hex or px.
6. Omit behaviors when element has no interaction.
7. Omit variants when element has only one visual state.
8. Ask all clarifying questions at once, never one by one.

FLOW

1. Trigger:
   • User invokes skill, or
   • Prompt asks to plan/analyse/document a UI graphic.
2. Check graphic:
   • Present → continue.
   • Missing → show ASK TEMPLATE, stop.
3. Read user description (if provided) — note any named features, flows, or context.
4. Scan graphic top-to-bottom, left-to-right.
   • Identify every distinct visible UI element.
5. For each element:
   • Name it clearly ("Primary CTA Button", "Search Input", "User Avatar Menu").
   • List behaviors — interactions and side-effects inferrable from context.
   • List variants — visual states visible or reasonably expected.
6. Output the element list as returned text.
   • If user asked to save to a file → write the same content to the requested path.
7. After the element list, output a ## Structure section — a spatial layout map showing which elements belong to which region and how they sit side-by-side.
8. After the structure, add one-line notes for any element where an assumption was made.

OUTPUT SHAPE

## Elements

### <Element Name>

- behaviors: <interaction>; <side-effect>
- variants: <state1>, <state2>, <state3>

## Structure

<Region>
  <ElementA> | <ElementB>

<Region>
  <ElementC>
  <ElementD>

Fields (## Elements):

• behaviors — what the element does on interaction (omit if non-interactive)
• variants — visual/state variations (omit if only one state)

Rules (## Structure):

• One line per region (Header, Hero, Sidebar, Main, Footer, Modal, …)
• Elements on the same row use | separator
• Elements stacked vertically go on separate indented lines
• Use element names exactly as they appear in ## Elements

ASK TEMPLATE

"Need the graphic first. Send screenshot, mockup, or design file — optionally add a short description of the UI — and I'll produce a flat element list with behaviors and variants."
