Don't Make Me Think — Usability Review & Redesign

Evaluate and improve UIs through Steve Krug's "Don't Make Me Think" principles. The report itself must practice what Krug preaches: scannable, visual, zero fluff. A human should skim it in 30 seconds; an AI agent should be able to parse it and start fixing.

When to Use

Trigger this skill when the user asks for a usability audit, UX review, or UI feedback on a screenshot, live URL, or HTML/CSS code. Do not use for visual/brand critique, WCAG accessibility audits, or backend/API review — route those elsewhere.

Instructions

Follow this workflow to keep the agent's context budget tight:

1. Check Prerequisites — confirm input type and access (see below).
2. Process Input — handle per the Input Handling table.
3. Evaluate — apply applicable lenses from The Ten Lenses (see references/krug-principles.md for token-efficient deep dives).
4. Generate Report — use the Report Format template verbatim.
5. Redesign (optional) — only if user requests fixes; always confirm before destructive edits.
