How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
1 rule. 0 are common, 0 are distinctive, and 1 is very specific to this project.
0
Common
Most of the 5 edited versions we read keep these.
0
Distinctive
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
- Very specific: line 12
Update baselines on purpose with npx playwright test --update-snapshots, and review the diff in the PR.
“Common” is measured: kept by at least 6 in 10 of the 5 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Visual testing
- Decide what a screenshot should prove: layout and branding of key pages and components, not dynamic data.
- Playwright built-in:
await expect(page).toHaveScreenshot('checkout.png', {
mask: [page.getByTestId('timestamp')], maxDiffPixelRatio: 0.01, animations: 'disabled' });Update baselines on purpose with npx playwright test --update-snapshots, and review the diff in the PR.
3. Make it stable: fixed viewport, fonts and locale; seeded data; mocked time; masked or hidden dynamic regions; generate baselines on the same OS/browser as CI (e.g. in the Playwright Docker image).
4. Hosted tools: Applitools Eyes (Visual AI match levels), Percy (BrowserStack), Sauce Visual. Use them for cross-browser coverage and a review workflow.
5. Python/Selenium: compare against reviewed baselines with a diff library (e.g. Visual Guard, see tools-and-libraries).
6. Review flow: a diff fails the build → a human accepts the new baseline or files a bug. Never auto-accept.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
