Prototype

Skill: Prototype & Research

Step 0 — is the kit here? This skill reads files from the kit. Check once: ls ${CLAUDE_SKILL_DIR}/../../../tokens >/dev/null 2>&1 && echo KIT_OK || echo KIT_MISSING On KIT_MISSING only the skill folders were installed, which is what npx skills add does. Say so plainly, point the user at npx ux-ui-agent-skills init or the plugin install, and stop. Do not guess the contents of a file you could not open.

Guide work through the right fidelity level with validation.

Steps

1. Read ${CLAUDE_SKILL_DIR}/../../../workflows/prototyping.md (5-level fidelity ladder, journey mapping template, usability-testing script, sample data).
2. Identify the current need and pick the lowest fidelity that answers it — never skip levels:
   • Content-first (info needs) → Wireframe (layout/nav) → Low-fi (task completion) → High-fi (visual/a11y) → Code (feasibility/perf).
3. For flows: produce a user-journey map with decision points, error paths, and edge cases.
4. For validation: define the usability test (tasks, success criteria, 5-user rule) using the script.
5. High-fi/code steps pull tokens (${CLAUDE_SKILL_DIR}/../../../tokens/*), components (${CLAUDE_SKILL_DIR}/../../../components/*), taste (${CLAUDE_SKILL_DIR}/../../../taste/*), and a11y (${CLAUDE_SKILL_DIR}/../../../accessibility/*).

Output

The artifact at the chosen fidelity + an explicit "what we validate next" plan.

Verification (before declaring done)

• The fidelity matches the question being answered — no level skipped.
• Flows include decision points, error paths, and edge cases (empty/loading/overflow), not just the happy path.
• A concrete validation step is named (tasks + success criteria), not "test later".
• High-fi/code artifacts pass the same token + a11y bar as design-code (no hardcoded values, contrast, states).
