The file

We split this skill into the rules it gives an agent

1 rule. About 0 are common, 1 is distinctive, and 0 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.

  • 0

    Very specific

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

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Wait 1 second for reflow

    line 37

≈ “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.

Responsive Screenshots

Screenshot a page at every common viewport size. No signup required.

Prerequisites

  • Playwright MCP (comes with Claude Code)

Trigger

  • "Responsive screenshots of https://..."
  • "How does my site look on mobile?"
  • "Screenshot this page at different sizes"

Workflow

  1. For each viewport, resize and screenshot:
NameWidthHeightDevice
Mobile375812iPhone 14
Tablet7681024iPad
Laptop1280800MacBook
Desktop19201080Full HD
Ultrawide2560108034" monitor
  1. For each size:
    • mcp__playwright__browser_resize to the viewport
    • Wait 1 second for reflow
    • mcp__playwright__browser_take_screenshot
    • Note any visible issues (overflow, overlap, hidden content)
  2. Analyze screenshots for common responsive issues:
    • Horizontal scroll on mobile (content wider than viewport)
    • Text too small to read on mobile (< 14px)
    • Touch targets too small (< 44x44px)
    • Navigation not collapsing to hamburger on mobile
    • Images overflowing containers
    • Fixed-width elements breaking layout
  3. Output:
## Responsive Report: [URL]

### Screenshots Captured
- Mobile (375px): screenshot_mobile.png
- Tablet (768px): screenshot_tablet.png
- Laptop (1280px): screenshot_laptop.png
- Desktop (1920px): screenshot_desktop.png
- Ultrawide (2560px): screenshot_ultrawide.png

### Issues Found
1. [MOBILE] Horizontal scroll detected — hero section overflows
2. [MOBILE] Navigation menu not collapsing — overlaps content
3. [TABLET] Card grid shows 3 columns, text truncated

### Looks Good
- Desktop and ultrawide layouts render correctly
- Images are responsive
- Footer stacks properly on mobile

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
What did you use it for? e.g. Reviewing pull requests in a Rails app

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.
