Text and Mermaid wireframes — produce screen-level layouts with content hierarchy, component placement, and interaction annotations. Use when asked to "wireframe this", "sketch the UI", "layout for this screen", "lo-fi mockup", "screen design", or "what should this page look like".

Default to executing. You know the conventions. Ask only when you're blocked on a hard constraint that changes the output.
You need three things before drawing anything:
If you have a Helm brief or product description, extract these directly. With a clear brief, you should be able to produce the wireframe without asking anything.
Ask only if: the screen handles a destructive action, requires a specific data model, or has access/permission logic that changes the layout. One targeted question, not a discovery session.
Before laying out the screen, check how this screen type is handled in the wild.
For the screen type (e.g., data table, settings page, onboarding step, multi-step form), identify:
State your pattern decision before wireframing: "Following [pattern] because [reason]" or "Breaking [pattern] because [reason]."
One paragraph. This prevents "why does it look different from everything else?" in review.
List every element needed on this screen, in priority order. Highest priority = most prominent position.
1. [Primary content — the most important thing the user needs to see or do]
2. [Secondary element]
3. [Tertiary element]
4. [Supporting navigation / wayfinding]
5. [Metadata / secondary info]
Cut anything not serving the primary job. If you're listing more than 8 elements, you're designing two screens.
Produce a text-based wireframe using ASCII box-drawing characters. Be specific about labels — not "[button]" but "[Save changes]". Not "[list]" but "[Project list — sorted by last modified]".
┌─────────────────────────────────────────────────────────┐

├─────────────────────────────────────────────────────────┤

└──────────────────┴──────────────────────────────────────┘
Include the empty state in the same wireframe pass — don't defer it:
┌─────────────────────────────────────────────────────────┐
│ │
│ [ Icon or illustration ] │
│ │
│ You don't have any [items] yet. │
│ [Items] let you [do the core job in │
│ one concrete sentence]. │
│ │
│ [Create your first item →] │
│ │
└─────────────────────────────────────────────────────────┘
Empty state copy must describe the value, not just the absence. "No projects yet" is not an empty state — it's a dead end.
After the wireframe, number every interactive element and annotate the behavior. Be specific — what happens, what state changes, what the user sees next.
① [Primary CTA] — creates a new item, opens inline form below the header (not a modal)
② [Item card] — tappable entire card, navigates to /items/:id detail view
③ [Filter A] — filters list in-place; no page reload; updates URL query param
④ [Load more] — appends next 20 items; button becomes "Loading..." during fetch; hidden when all items loaded
⑤ [Empty state CTA] — navigates to /items/new onboarding flow; only rendered when count === 0
State how the layout adapts on mobile. Three sentences maximum — if it needs more, the layout is too complex.
Before handing off, check:
[ ] Primary job is served without the user having to hunt
[ ] Primary action is the most visually prominent interactive element
[ ] Empty state is wireframed with real copy (not "[empty state message]")
[ ] Every interactive element has an annotation
[ ] Error state or validation behavior noted for any form inputs
[ ] Responsive behavior stated
[ ] Pattern decision documented (fit or break, with rationale)
If all seven are checked: ship it. Prism and Form don't need more fidelity than this — they need specificity about hierarchy and behavior, which is what this delivers.
