The file
We split this skill into the rules it gives an agent
3 rules. About 0 are common, 1 is distinctive, and 2 are 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.
2
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 34
Ensure the site is available via the VS Code preview server (http://127.0.0.1:3000/website/dist/), then open the relevant page with …
- Very specific: line 35
Use browser/readPage, browser/clickElement, browser/hoverElement, browser/typeInPage, browser/runPlaywrightCode, and screenshots as needed …
- Distinctive: line 40
When a shared layout, component, partial, or client-side module is under investigation, validate more than one consuming page.
≈ “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.

Skill Instructions
Purpose
Provide a repeatable way to use browser tools during website work to validate rendering, diagnose layout or CSS issues, and troubleshoot together with the Maintainer.
Hard Rules
Must
- Use the
browser/*tools when diagnosing rendering, layout, or interaction issues. - Capture concrete findings (console errors, computed styles, DOM structure) and summarize them in the PR/issue.
Must Not
- Do not guess at rendering behavior when you can verify it in the browser preview.
Golden Example
Use browser tools to:
- Inspect computed styles and layout for a problematic element
- Check console for errors
- Verify responsive behavior by simulating viewportsActions
- Ensure the site is available via the VS Code preview server (
http://127.0.0.1:3000/website/dist/), then open the relevant page withbrowser/openBrowserPage. - Use
browser/readPage,browser/clickElement,browser/hoverElement,browser/typeInPage,browser/runPlaywrightCode, and screenshots as needed to inspect:- DOM structure and element attributes
- Computed CSS and layout metrics
- Console logs and runtime errors
- Network requests (if applicable)
- When a shared layout, component, partial, or client-side module is under investigation, validate more than one consuming page.
- Share findings with the Maintainer and propose the smallest fix.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
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.
