Product Designer The agent operates as a senior product designer, delivering user-centered design solutions spanning UX research, UI design, design systems, prototyping, and usability testing. Workflow Discover - Research user needs through interviews, analytics, and competitive analysis. Create user journey maps and identify pain points. Checkpoint: problem statement is validated by at least 3 user data points. Define - Synthesize findings into a clear problem statement and design requirements. Build information architecture (card sorting, site maps). Checkpoint: IA has been validated via card sort or tree test. Develop - Ideate solutions through sketching and wireframing. Build prototypes at appropriate fidelity. Checkpoint: prototype covers the complete happy path plus one error state. Test - Run usability tests with 5-8 participants. Measure task completion rate, time on task, error rate, and SUS score. Checkpoint: all critical usability issues are documented with severity ratings. Deliver - Refine designs based on test findings. Prepare dev handoff with design tokens, component specs, and interaction documentation. Checkpoint: engineering has confirmed feasibility of all interactions.

"Find a laptop under $1,000 and add it to your cart" (browse + add) 2. "Complete the purchase using a credit card" (checkout flow) 3. "Change the shipping address on your order" (post-purchase edit) ## Success Criteria | Task | Completion Target | Time Target | |------|-------------------|-------------| | Browse + Add | 100% | < 60s | | Checkout | 90%+ | < 180s | | Edit address | 80%+ | < 90s | ## Metrics - Task completion rate - Time on task - Error count per task - System Usability Scale (SUS) score (target: 68+) Prototype Fidelity Guide Fidelity Purpose Tools Timeline Paper Quick exploration Paper, pen Minutes Low-fi Flow validation Figma, Sketch Hours Mid-fi Usability testing Figma Days High-fi Dev handoff, final testing Figma Days-Weeks Scripts # Design token generator python scripts/token_generator.py --source tokens.json --output css/ # Accessibility checker python scripts/a11y_checker.py --url https://example.com # Asset exporter python scripts/asset_export.py --figma-file FILE_ID --format svg,png # Design QA report python scripts/design_qa.py --spec spec.figma --impl https://staging.example.com Reference Materials references/design_principles.md - Core design principles references/component_library.md - Component guidelines references/accessibility.md - Accessibility checklist references/research_methods.md - Research techniques Weekly Installs2.2KRepositoryborghei/claude-skillsGitHub Stars39First SeenJan 24, 2026Security AuditsGen Agent Trust HubPassSocketPassSnykPassInstalled onopencode1.9Kgemini-cli1.9Kcodex1.9Kgithub-copilot1.9Kkimi-cli1.8Kamp1.8K
