# critique-accessibility Reviews an HTML page or fragment (markdown where its structure maps cleanly to HTML, such as headings, links, and images) against WCAG 2.2 AA, covering both success-criterion levels A and AA required for AA conformance. The artifact claim is narrow and static: this skill evaluates markup and declared CSS as text, never a rendered page, a running application, or live keyboard and pointer interaction. Four WCAG 2.2 success criteria that require observing a page respond to input over time (No Keyboard Trap, Timing Adjustable, Pointer Gestures, Dragging Movements) are out of this skill's reach for that reason and are not in its registry; see `references/WCAG.md`, "Scope", for the full boundary and reasoning. ## Contract Every finding this skill emits conforms to `contract/critique-contract.schema.json`.

This is the first choice every time, and generated or hand-written markup usually carries ids. 2. **A CSS selector in double quotes** for an element with no id: `"main > s...
