[What's working well and should be preserved] 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 ) 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 ) 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 ) 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 ) 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
