| description | [Project Management] Use when you need to create UI/UX design specifications from requirements, PBIs, or user stories. Use --mode=wireframe to convert hand-drawn/digital wireframes or UI sketches into structured specs. |
[BLOCKING] Execute skill steps in declared order. NEVER skip, reorder, or merge steps without explicit user approval.
[BLOCKING] Before each step or sub-skill call, update task tracking: set in_progress when step starts, set completed when step ends.
[BLOCKING] Every completed/skipped step MUST include brief evidence or explicit skip reason.
[BLOCKING] If Task tools are unavailable, create and maintain an equivalent step-by-step plan tracker with the same status transitions.
Quick Summary
Goal: Create structured UI/UX design specification documents from requirements or PBIs for developer handoff.
Workflow:
- Read Source โ Extract UI requirements from PBI, story, or Figma URL
- Determine Complexity โ Quick Spec (sections 1-4) vs Full Spec (all 7 sections)
- Build Component Inventory โ List new vs existing components
- Define States & Tokens โ Interactions, design tokens, responsive breakpoints
- Save Artifact โ Output to
team-artifacts/design-specs/
Key Rules:
- If Figma URL provided โ auto-routes to
/figma-design for context extraction
- If wireframe image provided (hand-drawn/digital/tool-export) โ handled internally via
--mode=wireframe (see "Mode: wireframe" below)
- If screenshot provided โ uses
visual analysis tooling for design extraction
- Reference existing design system tokens from
docs/project-reference/design-system/
- Component patterns:
docs/project-reference/frontend-patterns-reference.md
- Include accessibility requirements (keyboard nav, ARIA labels, contrast)
- [BLOCKING] Tech-agnostic output: spec prose/headings follow
docs/project-reference/spec-principles.md ยง3 โ describe components by UX role, not framework/library names; source paths and class names appear ONLY in evidence fields (**Evidence**, [Source:]), frontmatter, and Mermaid.
Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).
Design Specification
Create structured UI/UX design specification documents from requirements or PBIs for developer handoff.
When to Use
- A PBI or user story needs a design spec before implementation
- Translating requirements into concrete UI layout, states, and tokens
- Documenting component inventory and interaction patterns
- Creating responsive breakpoint specifications
When NOT to Use
- This skill auto-routes Figma URLs to
/figma-design; wireframes are handled internally via --mode=wireframe โ no need to call a separate skill
- Building the actual UI -- use
frontend-design
- Reviewing existing UI code -- use
web-design-guidelines
Prerequisites
Read before executing:
- The source PBI, user story, or requirements document
docs/project-reference/design-system/ -- project design tokens (if applicable)
- Existing design specs in
team-artifacts/design-specs/ for format consistency
Frontend/UI Context
When this task involves frontend or UI changes,
- Frontend patterns:
docs/project-reference/frontend-patterns-reference.md
- Styling/BEM guide:
docs/project-reference/scss-styling-guide.md
- Design system tokens:
docs/project-reference/design-system/README.md
Workflow
-
Read source input & route by type
| Input Detected | Detection | Action |
|---|
| Figma URL | figma.com/design or figma.com/file in text | Activate /figma-design to extract context, then continue |
| Image/screenshot | Image file attached to prompt | Use visual analysis tooling to extract design guidelines, then continue |
| Hand-drawn wireframe | Image + "wireframe"/"sketch" keyword | Run --mode=wireframe (internal โ see "Mode: wireframe" section) |
| PBI/story text | Acceptance criteria present | Extract UI requirements from text, continue |
| Verbal/text requirements | No image, no URL, no PBI | Clarify with user, then continue |
For ANY visual input: extract design context FIRST, then proceed to spec generation.
-
Determine spec complexity
IF single form or simple component โ Quick Spec (sections 1-4 only)
IF full page or multi-component view โ Full Spec (all 7 sections)
IF multi-page flow โ Full Spec + Flow Diagram
-
Build component inventory
- List all UI components needed
- Identify reusable vs feature-specific components
- Note existing components from shared component library or design system
-
Define states and interactions
- Default, hover, active, disabled, error, loading, empty states
- User interactions (click, drag, keyboard shortcuts)
- Transitions and animations
-
Extract design tokens
- Colors, typography, spacing, shadows, border-radius
- Reference existing design system tokens where possible
-
Document responsive behavior
- Mobile (320-767px), Tablet (768-1023px), Desktop (1024px+)
- What changes at each breakpoint (layout, visibility, sizing)
-
Save artifact โ pick the filename variant by artifact type:
- Design spec:
team-artifacts/design-specs/{YYMMDD}-designspec-{feature-slug}.md
- Accessibility audit:
team-artifacts/design-specs/{YYMMDD}-ux-audit-{feature-slug}.md
- Single-component doc:
team-artifacts/design-specs/{YYMMDD}-ux-component-{component-name}.md

Mode: wireframe (image โ spec)
Invoke with --mode=wireframe (or whenever a hand-drawn wireframe, digital wireframe, or UI sketch is the input). This mode is an INPUT adapter: it analyzes the image, then flows into the normal spec sections (Output Format) and the M1-M5 compliance gate. design-spec is the canonical owner of wireframeโspec conversion.
Input Routing (wireframe)
| Input | Detection | Action |
|---|
| Hand-drawn sketch photo | Image with rough/organic lines | Analyze with wireframe prompts (this mode) |
| Digital wireframe | Image with clean lines/shapes | Analyze with wireframe prompts (this mode) |
| Wireframe tool export | Image from Excalidraw/Balsamiq/MockFlow | Analyze with wireframe prompts (this mode) |
| Figma URL | figma.com in text | Route to /figma-design instead |
| App screenshot | Polished UI with real data | Route to /design --mode=screenshot instead |
Wireframe Analysis
Use visual analysis tooling with these prompts:
Prompt 1: Layout Extraction โ "Analyze this wireframe image. Identify: (1) page layout regions (header, sidebar, main, footer), (2) all UI elements with approximate position and type (button, input, table, card, dropdown, modal, tabs), (3) content hierarchy (what is primary vs secondary), (4) interactive elements, (5) any text labels or annotations, (6) navigation patterns."
Prompt 2: Component Identification โ "From the wireframe, list every distinct UI component. For each: name it descriptively, classify its complexity (primitive=single element, composite=grouped elements, section=page region), note its purpose."
Wireframe Output Generation
After image analysis, generate (per the SYNC:ui-wireframe-protocol block below):
- ASCII Wireframe โ Recreate layout using box-drawing characters
- Component Inventory โ List with tier classification (Common/Domain-Shared/Page)
- States Table โ Default, Loading, Empty, Error per view
- Component Decomposition Tree โ If detail level warrants (refine/story)
- Responsive Suggestions โ Based on layout complexity
Apply the M1-M5 Compliance for UI Specs gate (below) to all wireframe-derived prose: business-level component names, no code-prop refs, map to feature logic by logical ID, observable state transitions, rebuild-from-spec.
Mapped Business Operations
Emit this table linking each interactive component to the feature operations/rules it drives (logical ID is the primary spine; mark [UNVERIFIED โ needs feature-spec mapping] when the wireframe alone cannot determine it):
| Interactive Component | Interaction (observable) | Feature Operation / Rule (logical ID) | Notes |
|---|
| Primary Button | Click โ submit form | OP-XX | Triggers create/update operation |
| Filter Dropdown | Select โ reload list | OP-XX | Drives query/search operation |
| Row Action Menu | Click โ confirm dialog | BR-XX | Guarded by authorization rule |
Wireframe Output Formats
- Format A: PBI Section (default) โ output a standalone
## UI Layout section compatible with PBI/story templates (consumed by /pbi-mockup).
- Format B: Standalone Spec โ output to
team-artifacts/design-specs/{YYMMDD}-wireframe-spec-{slug}.md.
Confidence & Review (wireframe)
- Always display confidence level for wireframe interpretation (analysis is 70-80% accurate).
- Always recommend human review before proceeding to implementation.
- If confidence <70%: ask clarifying questions about ambiguous elements via
AskUserQuestion.

M1-M5 Compliance for UI Specs
See .claude/skills/shared/sdd-artifact-contract.md โ "AI-SDD Mandates (M1-M6)" for BLOCKING criteria. A UI spec MUST satisfy these before handoff:
- M1 โ Business-level component names. Name every component by its UX role โ Primary Button, Secondary Button, Modal Dialog, Data Table, Dropdown, Toast โ NEVER by a framework component class name or library import. FAIL on tech-term prose.
- M2 โ No code-prop refs in prose. Describe behavior and appearance in plain UX language. NEVER reference component-state props, CSS class names, framework directives, or selectors in prose. Those belong only in
**Evidence**/[Source:] carriers, frontmatter, and Mermaid.
- M3 โ Cross-reference by logical ID. For every behavior driven by feature logic, cite the driving operation or rule by its logical ID (
OP-/BR-/FR-) โ link UI behavior back to the feature spec, not to handler code. Keep any [Source: namespace/service/id] abstract anchor strictly in the Evidence carrier โ never physical code coordinates or repository-root paths.
- M4 โ Testable, unambiguous behavior. Every state and interaction MUST have exactly one valid interpretation and an observable completion marker. Replace vague phrases ("handle appropriately", "show feedback") with the concrete observable result.
- M5 โ Rebuild-from-spec. A reader with zero codebase knowledge MUST be able to rebuild this UI on ANY framework from the spec alone. If a marker is only resolvable by reading source, it fails M5 โ restate it as a visual/textual observable.
Observable State Definitions
Define every state by what a user can SEE (color, icon, position, text), the business meaning, and the operation/rule that triggers it โ NEVER by CSS class or component-state prop:
| State | Visual Markers (observable) | Business Meaning | Triggering Operation / Rule (logical ID) |
|---|
| Default | Primary fill color, enabled label, no spinner | Action available to the actor | OP-XX (entry state) |
| Loading | Spinner icon replaces label, control non-interactive | Operation in progress, awaiting result | OP-XX (request submitted) |
| Disabled | Muted/gray fill, label dimmed, no pointer affordance | Precondition not met / actor not permitted | BR-XX (authorization or guard rule) |
| Error | Error-color border, inline message text, alert icon | Operation rejected or validation failed | BR-XX (validation rule) |
| Empty | Placeholder illustration + guidance text, no data rows | No records exist for the current view | OP-XX (query returned zero results) |
| Success | Confirmation toast/checkmark, updated visible data | Operation completed and persisted | OP-XX (operation succeeded) |
Component States Checklist
Every interactive component MUST document all 7 states by their observable appearance and business meaning โ never by CSS class or framework prop (see M2):
- Default โ resting appearance; action available to the actor
- Hover โ pointer-over affordance change (cursor / elevation / color shift)
- Active โ pressed/engaged feedback during interaction
- Focus โ keyboard-focus indicator (visible ring/outline) for a11y traversal
- Disabled โ muted/non-interactive; precondition or permission not met
- Error โ validation/operation failure with inline message + alert affordance
- Loading โ in-progress indicator (spinner / skeleton); control non-interactive

Workflow Recommendation
MANDATORY IMPORTANT MUST ATTENTION โ NO EXCEPTIONS: If you are NOT already in a workflow, you MUST ATTENTION use AskUserQuestion to ask the user. Do NOT judge task complexity or decide this is "simple enough to skip" โ the user decides whether to use a workflow, not you:
- Run the design sequence (Recommended) โ
/design-spec โ /interface-design (product UIs) or /frontend-design (marketing/creative) โ /workflow-review-changes
- Execute
/design-spec directly โ run this skill standalone
[IMPORTANT] Use TaskCreate to break ALL work into small tasks BEFORE starting โ including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ATTENTION ask user whether to skip.
AI Mistake Prevention โ Failure modes to avoid on every task:
Re-read files after context changes. Context compaction, resume, or long-running work can make memory stale; verify current files before acting.
Verify generated content against source evidence. AI hallucinates APIs, names, claims, and document facts. Check the relevant source before documenting or referencing.
Check downstream references before deleting or renaming. Removing an artifact can stale docs, generated mirrors, configs, and callers; map references first.
Trace the full impact chain after edits. Changing a definition can miss derived outputs and consumers. Follow the affected chain before declaring done.
Verify ALL affected outputs, not just the first. One green check is not all green checks; validate every output surface the change can affect.
Assume existing values are intentional โ ask WHY before changing. Before changing a constant, limit, flag, wording, or pattern, read nearby context and history.
Surface ambiguity before acting โ don't pick silently. Multiple valid interpretations require an explicit question or stated assumption with risk.
Keep shared guidance role-relevant. Universal guidance must help every receiving skill or agent; code-specific obligations belong only in code-specific protocols.
UI System Context โ For ANY task touching .ts, .html, .scss, or .css files:
MUST ATTENTION READ before implementing:
docs/project-reference/frontend-patterns-reference.md โ component base classes, stores, forms
docs/project-reference/scss-styling-guide.md โ BEM methodology, SCSS variables, mixins, responsive
docs/project-reference/design-system/README.md โ design tokens, component inventory, icons
Reference docs/project-config.json for project-specific paths.
UI Wireframe Protocol โ Wireframe-to-implementation flow: (1) Process design input (Figma/screenshot/sketch via visual analysis tooling). (2) Create ASCII wireframe with box-drawing chars. (3) Build component inventory with tier classification (Common/Domain-Shared/Page). (4) Document states (Default/Loading/Empty/Error). (5) Map to design tokens. (6) Define responsive breakpoints. Search existing component libraries before creating new. Progressive detail by skill level (idea=sketch, story=full tree+specs).
Critical Thinking Mindset โ Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence >80% to act.
Anti-hallucination: Never present guess as fact โ cite sources for every claim, admit uncertainty freely, self-check output for errors, cross-reference independently, stay skeptical of own confidence โ certainty without evidence root of all hallucination.
- MANDATORY IMPORTANT MUST ATTENTION read frontend-patterns-reference, scss-styling-guide, design-system/README before any UI change.
IMPORTANT MUST ATTENTION follow wireframe protocol: ASCII wireframe, component inventory with tiers, states table, design tokens, responsive breakpoints.
MUST ATTENTION apply critical + sequential thinking โ every claim needs appropriate traced evidence (file:line for repo/code claims; source URL or artifact section for research, product, content, and docs claims); confidence >80% to act, <60% DO NOT recommend. Anti-hallucination: never present guess as fact, admit uncertainty freely, cross-reference independently, stay skeptical of own confidence.
MUST ATTENTION apply AI mistake prevention โ verify generated content against evidence, trace downstream references before deleting or renaming, verify all affected outputs, re-read files after context loss, and surface ambiguity before acting.
Prompt-Enhance Closing Anchors
IMPORTANT MUST ATTENTION follow declared step order for this skill; NEVER skip, reorder, or merge steps without explicit user approval

Closing Reminders
IMPORTANT MUST ATTENTION Goal: Create structured, tech-agnostic UI/UX design specification documents from requirements or PBIs for developer handoff.
Protocols in force (concise digest of the SYNC/shared blocks this skill carries):
-
AI Mistake Prevention: verify generated content against evidence, trace downstream references, verify all affected outputs, re-read after context loss, surface ambiguity.
-
UI System Context: read frontend-patterns, scss-styling, design-system before any UI change.
-
UI Wireframe: ASCII wireframe, tiered component inventory, states table, tokens, responsive breakpoints.
-
Critical Thinking: traced file:line proof per claim, confidence >80% to act.
-
MANDATORY IMPORTANT MUST ATTENTION break work into small todo tasks using TaskCreate BEFORE starting
-
MANDATORY IMPORTANT MUST ATTENTION search codebase for 3+ similar patterns before creating new code
-
MANDATORY IMPORTANT MUST ATTENTION cite file:line evidence for every claim (confidence >80% to act)
-
MANDATORY IMPORTANT MUST ATTENTION add a final review todo task to verify work quality
[TASK-PLANNING] Before acting, analyze task scope and systematically break it into small todo tasks and sub-tasks using TaskCreate.
[IMPORTANT] Analyze how big the task is and break it into many small todo tasks systematically before starting โ this is very important.
