## How to Use This Skill

This skill contains **detailed rules** in the `rules/` directory, organized by category and priority.

### Quick Start

| 🔴 CRITICAL | [User Research](rules/research.md) | Interviews, personas, and synthesis |
| 🔴 CRITICAL | [Accessibility](rules/accessibility.md) | WCAG compliance and inclusive design |
| 🟡 HIGH | [Information Architecture](rules/information-architecture.md) | Navigation and content organization |
| 🟡 HIGH | [Interaction Design](rules/interaction-design.md) | User flows and microcopy |
| 🟢 MEDIUM | [Visual Design](rules/visual-design.md) | Hierarchy, color, typography, and design systems |

## UX Design Process

### 1. **Discover & Research** (CRITICAL)
- Conduct user interviews and surveys
- Analyze existing analytics and heatmaps
- Perform competitive analysis
- Create empathy maps and identify pain points

### 2. **Define** (CRITICAL)
- Build user personas grounded in real data
- Map user journeys end-to-end
- Define problem statements using "How Might We" framing
- Prioritize features by user impact and feasibility

### 3. **Ideate & Design** (HIGH)
- Sketch multiple concepts before committing
- Create low → mid → high-fidelity wireframes
- Design responsive layouts for all breakpoints

### 4. **Prototype & Test** (HIGH)
- Build interactive prototypes for key flows
- Conduct moderated and unmoderated usability tests
- Measure task success rate, time on task, and error rate
- Iterate based on findings

### 5. **Handoff & Iterate** (MEDIUM)
- Prepare detailed design specifications with all states
- Document interaction states and edge cases
- Review implemented designs against specs

## Worked Example

Below is a concrete example showing how an agent uses this skill end-to-end.

### User Prompt

> "I'm building a SaaS onboarding flow. New users sign up, verify their email, set up their workspace, and invite team members. Can you review this plan and give me UX feedback?"

### Agent Response (applying UX rules)

---

#### Step 1 — Research Check *(from [research.md](rules/research.md))*

Before designing, validate your assumptions:
- **Do users need a workspace?** Interview 5-8 target users to confirm this matches their mental model. Ask: *"Walk me through setting up a new tool at work."*
- **Build a persona** to focus the flow. Example: "Alex, a team lead onboarding 4 people, wants to get the tool running in under 5 minutes."

#### Step 2 — Flow Analysis *(from [interaction-design.md](rules/interaction-design.md))*

Your proposed flow: **Sign Up → Verify Email → Set Up Workspace → Invite Team**

**Issues identified:**

| # | Issue | Severity | Recommendation |
|---|-------|----------|----------------|
| 1 | Email verification blocks the entire flow | Major | Let users proceed to workspace setup while verification happens in the background. Show a gentle reminder banner instead of a hard gate. |
| 2 | Four sequential steps with no progress indicator | Minor | Add a step indicator: "Step 2 of 4 — Set up your workspace" |
| 3 | "Invite Team" is mandatory but may not apply to solo users | Major | Make this step skippable: "Invite team members (you can do this later)" |

**Recommended flow:**
```
Sign Up → Workspace Setup → [Optional] Invite Team → Dashboard
              ↑                    ↑
          Progress bar         "Skip for now"
          Step 1 of 3          link available

Email verification runs in background → banner until confirmed
```

#### Step 3 — Accessibility Review *(from [accessibility.md](rules/accessibility.md))*

Ensure the onboarding flow meets WCAG AA:
- [ ] All form inputs have visible labels (not just placeholders)
- [ ] "Continue" buttons have minimum 44×44px touch targets
- [ ] Error messages are descriptive: *"Workspace name must be 3-50 characters"* not *"Invalid input"*
- [ ] Progress indicator is conveyed to screen readers via `aria-live`
- [ ] Color is not the only indicator of current step (use number + label)

#### Step 4 — Visual Hierarchy *(from [visual-design.md](rules/visual-design.md))*

- **Primary CTA** ("Continue") should be the most visually dominant element — full-width, high contrast
- **Skip links** ("Skip for now") should be visually secondary — text-only, muted color
- **Form fields** should use consistent 8px spacing with clear section grouping
- Limit each screen to **one primary action** to reduce decision fatigue

#### Summary

| Area | Status | Key Action |
|------|--------|------------|
| Research | ⚠️ Validate | Interview 5-8 users on their onboarding expectations |
| User Flow | 🔴 Redesign | Remove email verification blocker, make invite optional |
| Accessibility | 🟡 Review | Add visible labels, proper ARIA, and descriptive errors |
| Visual Design | ✅ Apply | F-pattern layout, single CTA per screen, 8px grid |
