Web Usability — Krug's Principles

Use When

• Steve Krug's web and mobile usability principles from Don't Make Me Think (3rd ed.). Load when designing web or mobile interfaces, navigation, home pages, forms, or planning usability testing. Covers Krug's 3 Laws, scanning behaviour, Billboard...
• 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 web-usability-krug 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.
