The repository describes itself as: A curated list of awesome skills for Cursor. The licence is CC0-1.0.
Example prompts
- “/responsive-testing”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 99cd265. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Responsive Testing loads about 514 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 211 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Responsive Testing
After a UI change, verify the app looks correct at all standard breakpoints.
Viewports to Test
| Name | Width | Tailwind |
|---|---|---|
| Mobile (small) | 375px | default |
| Mobile (large) | 428px | default |
| Tablet | 768px | md: |
| Desktop | 1280px | xl: |
| Ultrawide | 1536px | 2xl: |
Workflow
1. Navigate to the Page
Use browser_navigate to open the target URL (usually http://localhost:3000 or whatever the dev server is running on).
2. Test Each Viewport
For each viewport size:
- Resize the viewport using
browser_navigatewith viewport parameters, or usebrowser_snapshotto inspect the layout - Take a screenshot with
browser_take_screenshot - Check
browser_snapshotfor the aria tree — look for:- Content overflowing or hidden behind other elements
- Navigation that should collapse into a hamburger menu
- Text that's too small to read
- Buttons/links too close together (touch target issues)
- Horizontal scrollbars that shouldn't exist
3. Check for Common Breakage
- Overflow: Elements wider than the viewport causing horizontal scroll
- Collapsed layout: Flex/grid items that should stack on mobile but don't
- Hidden content: Elements that disappear at certain sizes without a menu toggle
- Font scaling: Text that's readable on desktop but tiny on mobile
- Fixed positioning: Modals, toasts, or sticky headers that break on small screens
- Images: Oversized images that don't scale down
4. Report
Responsive Test Results:
375px (mobile): PASS — layout stacks correctly
428px (mobile): PASS
768px (tablet): WARN — nav items overlap, need hamburger menu
1280px (desktop): PASS
1536px (ultrawide): WARN — content not centered, stretched too wideFix any issues found, then re-test the affected viewports.
