# Usability And Accessibility Review
Use for structured, evidence-tied critique, not taste.
## Evidence First
Identify:
- surface and task;
- user or segment;
- available evidence;
- what was not inspected;
- whether the claim needs live behavior, assistive technology, analytics, or user research.
Do not claim accessibility compliance from screenshots, mocks, or prose. Static review finds risks; compliance requires testable behavior.
With thin evidence, separate observed failures, heuristic risks, standards risks, and validation tasks.
## Review Lenses
Use these lenses:
- Nielsen: status visibility, real-world language, user control, consistency, error prevention, recognition over recall, flexibility, minimalist relevance, error recovery, help.
- Shneiderman: consistency, universal usability, feedback, closure, error prevention/handling, easy reversal, user control, reduced memory load.
- Cognitive walkthrough: for primary tasks, can users know the goal, notice the action, understand it, and see progress?
- Accessibility floor: WCAG 2.2 as testable baseline; APG/COGA as design guidance.
Accessibility checks:
- perceivable content and text alternatives;
- keyboard operation and focus order;
- visible focus;
- accessible names and roles;
- target size and pointer alternatives;
- contrast and non-color indicators;
- predictable navigation and help;
- reduced redundant entry;
- understandable language and recovery;
- motion, timeout, and seizure risks;
- cognitive supp
