scan_page — Scan a web page for WCAG accessibility issues.
verify_fix — Re-scan a specific element after applying an accessibility fix and confirm the violation is gone — closes the loop that find-only tools leave open.
diff_scan — Compare two scans of the same page and report what changed: `fixed[]` (in the baseline, gone now), `new[]` (regressions — not in the baseline, present now), `remaining[]` (still there).
start_audit — Kick off a FULL accessibility audit deliverable for a URL — a persistent, timestamped artifact, not an inline scan.
get_audit — Check an audit started with start_audit: returns overall status, per-step progress (scan → viewports → screenshots → agent → excel → publish), and — once complete — a severity summary plus short-lived download URLs for the report (JSON) and the Excel workbook.
flow_scan — Scan a multi-page user journey.
detect_framework — Detect which framework/stack a page uses (Tailwind, MUI, Bootstrap, WordPress, Next.
generate_ai_fix — Generate framework-aware fix alternatives for a specific accessibility issue.
