Laws of UX — Complete Reference

Use When

• Comprehensive named-law quick reference for all 30 Laws of UX (Yablonski) plus classic design heuristics. Load when citing, applying, or evaluating any named UX law by name. Covers Fitts, Hick, Miller, Jakob, Tesler, Postel, Doherty, Zeigarnik...
• 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 laws-of-ux 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.
