At a glance
A skill your agent uses when reviewing CI coverage, automated checks, or test strategy related to Use visual regression testing.
- Reviewing CI coverage
- SKILL.md covers Quick Reference, Check, Fix and Explain, plus 1 more section

What it does
Visual Regression is an agent skill from thedaviddias/Front-End-Checklist. Use when reviewing CI coverage, automated checks, or test strategy related to Use visual regression testing. Focus on whether the rule is continuously verified, not just documented.
Its SKILL.md is about 490 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 Visual regression testing. 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 Use visual regression testing
Example prompts
- “/visual-regression”
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
Visual Regression loads about 493 tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 50 tokens; SKILL.md has 209 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.

Use visual regression testing
Functional tests verify behavior but don't see your page. A CSS refactor might pass all unit and integration tests while completely breaking the layout — text overlapping images, buttons invisible, wrong colors. Visual regression testing acts as a safety net that reviews your actual rendered output, catching changes that no amount of JavaScript testing can detect.
Quick Reference
- Visual regression tests catch CSS regressions that functional tests miss
- Run screenshot comparisons in CI to block merges that break visual appearance
- Use component-level (Storybook) tests for focused, fast visual coverage
- Set pixel difference thresholds to avoid flaky tests from sub-pixel rendering
Check
Does this project have visual regression testing? What critical components or pages would benefit most from visual baselines?
Fix
Set up visual regression tests for the key components using Playwright's screenshot comparison or a tool like Chromatic.
Explain
Explain visual regression testing, how it differs from functional tests, and how to set up screenshot comparison in a CI pipeline.
Code Review
Review tests, CI workflows, and enforcement points related to Use visual regression testing. Flag exact gaps where the rule is not automatically verified or where failures do not block regressions.
