EAA Form Lint: WCAG 2.2 AA for HTML

Paste or open an HTML, Vue or Svelte template and this extension names every WCAG 2.2 Level AA form failure on its line, with the success-criterion number and the one-line fix.

It exists because generated markup fails in a very predictable way. A 70-line signup form written the way an assistant writes one — _fixtures/dirty.html in this repository — returns 28 findings across 15 success criteria (24 errors, 4 warnings). Six of those findings sit under the criteria that were added in WCAG 2.2: 2.5.7 Dragging Movements, 2.5.8 Target Size (Minimum), 3.3.7 Redundant Entry and 3.3.8 Accessible Authentication. Most models learned forms from WCAG 2.1-era code, so those four are the ones they keep getting wrong — autocomplete="off" on a password field, onpaste="return false", a 16px checkbox, a "confirm your email" field.

The repaired version of the same page, _fixtures/clean.html, returns 0 findings.

Why now

The European Accessibility Act (Directive (EU) 2019/882) has applied to new consumer-facing e-commerce, banking, ticketing and e-book services since 28 June 2025 — 440 days as of 2026-09-11. Member States enforce it through national market surveillance bodies, and the technical yardstick they point at is EN 301 549, which carries the WCAG success criteria. A finding arrives as a demand to fix a live service, not as a lint warning.

What the free command does

EAA Form Lint: Check this file runs 18 rules over the active editor and writes a report:

The rule table lives in ext/rules.json; the engine in ext/engine.js runs unchanged in Node and in the browser, so the free web page at https://getreadystack.com/tools/eaa-form-lint-wcag22 gives the same lines as the editor.

That is the whole job for one file, with no key.

The full version

EAA Form Lint: Audit the whole workspace scans every template at once and writes a dated evidence file you keep — one row per finding, per file, mapped to its WCAG 2.2 criterion. It is what you attach to an accessibility statement or hand to a client who asks what you checked and when. A licence key unlocks it: https://buy.polar.sh/polar_cl_O5AMXCnn3ZETWE939bA4zjzmM0KqLt9Yp76Xm2x1Pa1

Full workspace sweep and report: free for 7 days from your first sweep, then a licence key.

Yardstick: a WCAG audit from an accessibility vendor starts around $2,500 for one signup flow, and answers for the day it was run; this answers for every file, every time you save.

7-day full refund. One licence key per person or team seat.

Scope and honesty

This is a static text linter. It reads markup, not a rendered page, so it cannot judge colour contrast, reading order on screen, or anything that needs a live DOM. It finds the machine-checkable part — which is where generated code fails — and it never claims conformance on your behalf.
