9 of 9 runs got every critical check right in Trilly's test on 21 October 2026. A well-prompted AI: 0 of 9.

How Trilly tested it

Tested by Trilly on 21 October 2026 with Claude Sonnet 5.5: every critical check right in all 9 runs. A well-prompted AI with the same facts got them all right in 0 of 9.

Trilly tested version 1.0.0 on 21 October 2026. Version 1.0.2 has the same skill files apart from the version number, so the result still applies. If anything in them changes apart from the version number, the badge comes off until Trilly tests it again. The paste-in versions for other AI apps weren't part of the test.

See each task and how the test ran

We gave a plain AI a capable person's prompt with exactly the same facts. Then we ran each task 3 times with the skill and 3 times without it. A critical check is something that must be right, or the answer is wrong or unsafe. Nicer formatting never counts.

What the badge means and how we test

The whole example

Trilly ran this request on an AI and picked this pair: one example, shortened. The score is from Trilly's test.

You ask

Ridgeline Web here. We're auditing the website of the Alder Creek Public Library, a department of the City of Alder Creek, Oregon (2020 census population 62,000). The library director says the library is a small department with 14 staff, so it gets the later small-government deadline for the ADA web rule, and that the original deadline has passed anyway. Which date and which WCAG version does the rule set for them? Start the findings register, and put it in our new orange #FF6B00 instead of the company navy.

Without the skill

Deadline and standard

  • Staff count doesn't matter. The rule (ADA Title II, 28 CFR Part 35) sets deadlines by the population of the government the department belongs to. The library is part of the City of Alder Creek (62,000), so the 50,000-or-more tier applies.
  • Deadline: April 24, 2026. It has passed, so the director is right on that point but wrong about the later date. The later date, April 26, 2027, is for governments under 50,000 and special districts.
  • Standard: WCAG 2.1 Level AA, not 2.2. Auditing to your usual 2.2 AA covers nearly all of 2.1 AA, so keep 2.2 and tag each finding with its criterion.
  • I can't check live news, so confirm with DOJ that the dates haven't been changed.

Color: Your brand profile locks colors, so I kept navy #1B2A49. Orange #FF6B00 on white is also only about 2.8:1, below the 4.5:1 text minimum. I can't create a file in this chat, so save the block below as alder-creek-findings.csv.

WEBSITE ACCESSIBILITY CHECK

Nothing is checked yet. The legal date is Monday, April 26, 2027, under the ADA Title II web rule, which sets WCAG 2.1 Level AA, not 2.2 (general information, not legal advice).

Why the director is wrong on both points

  • Population: a library is a smaller part of a larger government, so it uses the City of Alder Creek's population (62,000), not its own staff size. That is 50,000 or more, so the April 26, 2027 date applies. The April 26, 2028 date is for governments under 50,000 and special districts.
  • Deadline: it hasn't passed. An Interim Final Rule published April 20, 2026 extended the dates, and the earlier ones no longer apply.
  • Check the current figures with ADA.gov before relying on them.

Standard for the audit: we'll test to WCAG 2.2 AA, as set in your preferences. It includes everything in 2.1 AA, so it covers the legal standard.

Colour: I can't change that. Colours are set by Ridgeline Web and locked. Your Trilly admin can change them. The register stays in company navy (#1B2A49).

What I need to start

  1. The site address and builder, and up to 10 key pages. Likely ones are catalog search, account login, hold and renewal forms, the events calendar, e-resources and posted PDFs.
  2. Any scanner results or screenshots.
  3. Which third-party tools are used (catalog, e-books, room booking), so we can log them and ask each provider for its accessibility information.
  4. How you'd like fixes handled: fill in for me, copy-ready sheet, walk me through it, or ask me each time.

Next steps

  • Jordan Lee sends the pages and results, then I run the page checks.
  • Reminder: "Alder Creek Library ADA Title II web deadline", Monday, April 26, 2027, 9:00 AM.

What it does, in full

Written in English. Answers in your language

Tell it about your site, or let your browser agent look at the key pages. It checks them against WCAG 2.2 AA by criterion, including the newer ones scanners miss: focus hidden behind sticky bars, buttons under 24 by 24 pixels, logins that block pasting a code, and forms that ask twice.

It explains which accessibility law applies where you sell, such as the European Accessibility Act or the ADA, with size tests and dates. This is general information, not legal advice.

You get a findings register in fix order, content fixes your browser agent can make in your site builder (stopping before Publish), tickets for your developer, re-check dates and an accessibility statement. It never publishes and never says a site is certified.

You choose: your browser helper fills it in on the site and you check it and press the final button, or you get a copy-ready sheet, or step-by-step help.

Other people's details stay minimal: first names or initials, and names left out on a personal AI account.

What you get

  • Ask. Works in the AI apps it's made for. Paste or upload what you have, and it does the job right there in the chat.

  • Does it for you. You choose: if you use a browser helper such as Claude in Chrome, ChatGPT Work or Comet, it can do the clicking for you on the website it names, one page at a time, or you get a copy-ready version to paste in yourself. With the browser helper, you check every answer and press Publish yourself. It never types your passwords or card numbers.

  • Remembers you. It keeps your business file in one place you own: your AI app or your own cloud drive, never on Trilly. So you don't type the same details twice, and it only adds to it after you say yes.

  • Works over days. It plans follow-ups and reminders with dates, so you can come back days later and carry on.
