SKILL: wireframe

Purpose

Generate low-fidelity wireframes from user story files. Output is deterministic — given the same story and layout hints, the same wireframe structure is produced. Three output formats: ASCII (default), SVG, HTML. Human approval is required before the wireframe feeds downstream mockup work.

Inputs

Field	Source	Example
story_file	path to story markdown	docs/stories/auth-reset-0001.md
ui_components	derived from story Gherkin	form, button, error message
stack	project.config.yaml	react-mantine

Outputs

The required files depend on design.target in project.config.yaml (default web) — see Target awareness:

File	Location	Targets
<story-id>.wireframe.md	docs/design/wireframes/	web + tui — ASCII layout + approval metadata
<story-id>.wireframe.excalidraw	docs/design/wireframes/	web + tui — editable Excalidraw diagram
<story-id>.wireframe.html	docs/design/wireframes/	web only — browser-previewable static wireframe

A wireframe stage that produces fewer than the files required for the active target is incomplete. Do not PAUSE or mark DONE without them.

Target awareness

design.target decides which files are required:

• web — <id>.wireframe.md (ASCII) + .html (preview) + .excalidraw.
• tui — <id>.wireframe.md (ASCII/box-drawing) + .excalidraw. No .html.

Use box-drawing primitives for tui layouts, label panes/overlays/status bar, and include the keybinding legend and focus order inline in the .md. The Excalidraw generator below applies to both targets; the HTML generator is web only.

ASCII Wireframe Primitives

Use these consistently across all wireframes:

┌─────────────────────────────────┐   ← container / card
│  [Label]  [Input Field      ]   │   ← label + text input
│  [Button: Primary Action    ]   │   ← primary button
│  [Button: Secondary]            │   ← secondary button
│  ○ Option A  ○ Option B         │   ← radio group
│  ☐ Checkbox label               │   ← checkbox
│  ▼ Dropdown / Select            │   ← select / combobox
│  ──────────────────────         │   ← divider
│  ⚠ Error message text           │   ← validation error
│  ✓ Success confirmation         │   ← success state
└─────────────────────────────────┘

[Nav: Logo | Item 1 | Item 2 | CTA]  ← navigation bar
[ Sidebar  ][     Main Content    ]  ← two-column layout
[  Col 1  ][  Col 2  ][  Col 3  ]   ← three-column grid
[         Full-width Banner         ]← hero / header band

ASCII Wireframe — Example (Password Reset)

┌──────────────────────────────────────┐
│            Reset Password            │
│                                      │
│  Email                               │
│  [                              ]    │
│                                      │
│  ⚠ No account found for this email  │  ← error state
│                                      │
│  [Button: Send Reset Link       ]    │
│                                      │
│  ← Back to Login                     │
└──────────────────────────────────────┘

Generate Wireframe Files

For each story, produce all three output files. Run these steps:

STORY_FILE="docs/stories/auth-reset-password-20250416143000-0001.md"
STORY_ID=$(python3 -c "
import re
m = re.search(r'^id:\s*[\"\'](.*?)[\"\']', open('$STORY_FILE').read(), re.MULTILINE)
print(m.group(1) if m else 'unknown')
")
mkdir -p docs/design/wireframes

Step 1 — Write ${STORY_ID}.wireframe.md (ASCII layout + approval metadata):

---
story_id: "{story_id}"
story_file: "{story_file}"
status: draft          # draft | approved | rejected
approved_by: null
approved_at: null
---

## Wireframe: {story title}

### Default state
{ASCII wireframe}

### Error state
{ASCII wireframe — validation error}

### Success state
{ASCII wireframe — confirmation}

### Interaction Notes

- Tab order: {list of focusable elements in tab sequence}
- Primary action: {describe}
- Error handling: {describe visible error states}

### Approval

- [ ] Approved by product owner
- [ ] Approved by UX lead (if applicable)

Step 2 — Write ${STORY_ID}.wireframe.html (see HTML template below)

Step 3 — Write ${STORY_ID}.wireframe.excalidraw (see Excalidraw template below)

After writing the files required for the active target, verify they exist (web: md, html, excalidraw; tui: md, excalidraw):

ls docs/design/wireframes/${STORY_ID}.wireframe.md
ls docs/design/wireframes/${STORY_ID}.wireframe.excalidraw
# web target also:
ls docs/design/wireframes/${STORY_ID}.wireframe.html 2>/dev/null || true

If any required file is missing, produce it before continuing.

HTML Wireframe (web target only)

For web targets, always generate the HTML wireframe. Skip this section entirely for tui. Use multiple <section> blocks for multi-state wireframes (default, loading, error, success, empty).

HTMLEOF

Extend with real field names, content, and states from the story Gherkin. One <div class="state"> block per Gherkin scenario.

Excalidraw Wireframe (always required)

Always generate the Excalidraw file — every story, every run. Excalidraw is the canonical editable wireframe format reviewers annotate.

Write the file as valid JSON to docs/design/wireframes/${STORY_ID}.wireframe.excalidraw. Each UI element is one entry in the elements array. Use the element templates below, copy and adapt:

python3 - <<'PYEOF'
import json, pathlib, os

story_id = os.environ.get("STORY_ID", "unknown")
out = pathlib.Path(f"docs/design/wireframes/{story_id}.wireframe.excalidraw")
out.parent.mkdir(parents=True, exist_ok=True)

PYEOF

Adapt element positions and labels to match the actual story screens. Add more rect/text/input_field/button_primary calls per Gherkin scenario. Do not leave placeholder text ({Screen Title}) in the final file.

Approval Gate

All three files must exist and the .md must be status: approved before mockup or ui-mockup-builder proceeds:

python3 - <<'EOF'
import re, sys, pathlib
sid = open(".claude/state/maple.json").read()  # or pass STORY_ID
# Check required artifacts exist (html is web-only)
cfg = open("project.config.yaml").read() if pathlib.Path("project.config.yaml").exists() else ""
tm = re.search(r'^\s*target:\s*(\w+)', cfg, re.MULTILINE)
target = tm.group(1) if tm else "web"
exts = ["md", "excalidraw"] if target == "tui" else ["md", "html", "excalidraw"]
for ext in exts:
    p = pathlib.Path(f"docs/design/wireframes/{sid}.wireframe.{ext}")
    if not p.exists():
        print(f"BLOCKED: missing {p}")
        sys.exit(1)
# Check approval status in .md
md = pathlib.Path(f"docs/design/wireframes/{sid}.wireframe.md").read_text()
m = re.search(r'^status:\s*(\w+)', md, re.MULTILINE)
status = m.group(1) if m else 'draft'
if status != 'approved':
    print(f"BLOCKED: wireframe {sid} not approved (status={status})")
    sys.exit(1)
print("approved — all three artifacts present")
EOF

Failure Modes

Condition	Action
Story has no Gherkin	Generate skeleton wireframe with placeholder states. Log NO_GHERKIN — skeleton only.
docs/design/wireframes/ missing	Create it.
Wireframe .md exists and is approved	Do not overwrite. Log SKIP — approved wireframe exists.
Wireframe .md exists and is draft	Overwrite only if story Gherkin has changed.
.html or .excalidraw missing despite .md existing	Generate the missing file(s) immediately.
