Keep Accessibility From Regressing
Keep Accessibility From Regressing: what it does, its label on each agent, what it misses, and examples.
Catalog policy no-a11y-regression, version 1.1.3, labelled blocks on Claude Code.
What it does
Trigger: remediating accessibility, editing markup, emptying or removing an alt, aria-label, label or lang that an element already had, deleting a flagged element. avoid: breaking a requirement the previous revision met; interrupting a correct fix.

What it misses
