A practice-driven approach to user experience design that replaces heavy deliverables with rapid experimentation, cross-functional collaboration, and continuous learning. Based on a fundamental truth: teams that obsess over pixel-perfect specs before testing with real users waste months building the wrong thing. Lean UX shifts the question from "What should we design?" to "What do we need to learn?"
Lean UX is a community-contributed Claude Code skill in the ux-research sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/lean-ux/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when the user mentions "Lean UX", "design hypothesis", "UX experiment", "collaborative design", or "outcome over output". Covers hypothesis statements, MVPs for UX, and cross-functional collaboration.
The Lean UX Claude Code skill is built for product managers, product designers, and cross-functional teams planning, shipping, and measuring product features. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
