At a glance
A skill your agent uses when reviewing CI coverage, automated checks, or test strategy related to Test on real mobile devices and viewports.

What it does
Mobile Testing is an agent skill from thedaviddias/Front-End-Checklist. Use when reviewing CI coverage, automated checks, or test strategy related to Test on real mobile devices and viewports. Focus on whether the rule is continuously verified, not just documented.
Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/rule.md`).
It sits in Testing & QA, covering Mobile testing and debugging and Test strategy. It works with Playwright. The repository describes itself as: 🗂 The essential checklist for modern web development, for humans and AI agents. The licence is MIT.
When your agent uses it
- Reviewing CI coverage
- Automated checks
- Test strategy related to Test on real mobile devices and viewports
Example prompts
- “/mobile-testing”
What it can do on your machine
Read from SKILL.md and the folder at commit e8d14d0. 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
Links to these hosts (documentation or services it may open):
frontendchecklist.io
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
Mobile Testing loads about 517 tokens when it runs, and up to ~1.6k if it reads all its reference files. Until then it costs about 52 tokens; SKILL.md has 228 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.

Test on real mobile devices and viewports
More than 55% of global web traffic comes from mobile devices. Mobile browsers have different rendering engines, different font rendering, limited memory, real touch events that differ from mouse events, and system UI (notch, home indicator, keyboard) that intrudes on your layout. Issues like sticky hover states, touch target sizes, and keyboard layout shifts only appear on real devices.
Quick Reference
- Desktop DevTools device emulation catches layout issues but not real touch behavior
- Test on at least one Android (Chrome) and one iOS (Safari) real device
- Test common viewport breakpoints: 375px (iPhone SE), 390px (iPhone 14), 768px (iPad)
- Use BrowserStack or similar services for testing on devices you don't own
Check
Does this project have any mobile-specific test configurations? Check for Playwright device emulation, mobile viewport tests, or notes about mobile testing.
Fix
Add Playwright tests using mobile device presets to cover key user flows on mobile viewports.
Explain
Explain the difference between DevTools emulation and real device testing, common mobile-specific issues to test for, and how to use Playwright's device emulation.
Code Review
Review tests, CI workflows, and enforcement points related to Test on real mobile devices and viewports. Flag exact gaps where the rule is not automatically verified or where failures do not block regressions.
