Lean UX Validation

Use When

• Hypothesis-driven UX validation process from Laura Klein's UX for Lean Startups. Use BEFORE building any feature to validate it is worth building. Covers problem/market/product validation, 5-user research, fake button testing, interview...
• The task needs reusable judgment, domain constraints, or a proven workflow rather than ad hoc advice.

Do Not Use When

• The task is unrelated to lean-ux-validation or would be better handled by a more specific companion skill.
• The request only needs a trivial answer and none of this skill's constraints or references materially help.

Required Inputs

• Gather relevant project context, constraints, and the concrete problem to solve.
• Confirm the desired deliverable: design, code, review, migration plan, audit, or documentation.
