Skill1 starsChanged 6 days agoMITView on GitHub

Crawl a website in a headless Chromium browser and produce a prioritized QA report — console errors, failed requests, broken images and links, mobile sideways-scroll, missing viewport/title/description/Open Graph tags, images without alt, unlabeled form fields, page weight and load time — with desktop and mobile screenshots. Use before handing a site to a client, after a deploy, or when asked "check my site / is anything broken".

The file

We split this skill into the rules it gives an agent

2 rules. About 0 are common, 1 is distinctive, and 1 is very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈1

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Read report.md and LOOK at both screenshots.

    line 20
  2. Distinctive:

    When fixing issues, re-run against the same URL to confirm.

    line 25

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

site-qa

scripts/site-qa.mjs is zero-dependency Node 22+. It launches its own headless Chrome / Edge / Brave / Chromium with a temporary profile, so it never touches the user's browser or logins. Set BROWSER=/path/to/chrome if none is found.

node site-qa.mjs https://example.com                     # up to 20 same-site pages
node site-qa.mjs https://example.com --max-pages 50 --out qa-report
node site-qa.mjs http://localhost:5173 --no-external      # skip outbound link checks
node site-qa.mjs https://example.com --keep-query          # treat ?a=1 and ?a=2 as different pages

Output in --out (default qa-report/): report.md (issues by severity, then a per-page table), report.json, desktop.png (1366×900) and mobile.png (390×844) of the start page.

How to use the report

  • Read report.md and LOOK at both screenshots. Many layout problems only show up visually.
  • High = broken for users: page errors, JS exceptions, failed requests, broken images, broken links (to pages, same-site files like PDFs, and outbound), sideways scroll on mobile, no viewport tag. Fix these first.
  • Medium = hurts reach or accessibility: missing description or Open Graph tags (plain WhatsApp/Facebook link previews), missing <h1>, images without alt, unlabeled inputs, pages over 3 MB or slower than 8 s.
  • Low = polish: lang attribute, favicon, duplicate titles, tiny tap targets, empty links.
  • "Link refused the checker" means the site blocks bots (LinkedIn, Instagram and others do). Check those by hand; they aren't proven broken.
  • When fixing issues, re-run against the same URL to confirm. After a deploy, run it against the live URL, not localhost.

Notes

  • Each page loads twice, once at desktop and once at mobile size with a mobile user agent. Errors seen only on mobile are labeled as such.
  • It crawls only same-origin links found in <a href>. Pages reachable only through JS navigation or forms won't be found. Pass their URLs as separate runs. If the start URL redirects (http → https, apex → www), the crawl follows the final origin.
  • Linked same-site files (PDFs, images, feeds) are checked with a plain request, also under --no-external; up to 100 such and outbound links per run.
  • It never submits forms or clicks buttons, so it's safe to run against production.
