• aether_check_html

  Analyze an HTML snippet for WCAG accessibility issues without needing a live URL or browser. Uses static heuristic checks and optionally enriches results with RAG-powered fixes. Use this when a developer pastes HTML or asks about a component's accessibility.

• aether_get_fix

  Get a RAG-powered fix OR explanation for a WCAG violation. Pass `html` (the failing element) to get a concrete fixHtml plus a measured verification. Omit `html` to get a rule-level explanation (WCAG success criteria, technique code examples, failure patterns, and fix guidance). Requires ALLCHEMY_API_KEY for RAG output; falls back to templates without it.

• aether_scan_and_fix

  START HERE for any accessibility / a11y / WCAG question about a URL. Scans the page in a real browser (Playwright + axe-core, desktop/tablet/mobile) for WCAG 2.1 AA violations AND generates grounded fixes in one call; do not fetch and read the page HTML yourself instead. Pass `url` for a page or the `spa` block for a multi-route single-page app. Returns violations grouped by severity, each with fixHtml (a SUGGESTION — nothing is modified), explanation, WCAG techniques, confidence tier, and a measured `verification` block (verified / targetCleared / regressions / newViolations / complianceDelta…

• aether_submit_feedback

  Submit developer feedback on a previously returned WCAG fix/artifact, keyed by its finding_id. Records a rating plus an optional reason_code and the code the developer actually shipped, so the fix pipeline can learn from misses. Requires ALLCHEMY_API_KEY.

• aether_verify_fix

  Deterministically verify a WCAG fix with the real Playwright + axe-core engine. URL mode re-scans a live page; snippet mode diffs original vs fixed HTML before deploy. Returns MEASURED facts: verified, targetCleared, regressions (what the fix took away from the element: a lost ARIA state, focus, name or interactive role; snippet mode), newViolations, resolvedViolations and complianceDelta. `verified` (targetCleared with no regressions) is the authoritative "did the fix work?" signal.
