What it does
Visual Regression Lab is an agent skill from TheGoat395/Codex-Skills. Compare captures; stitch lazy/animated pages.
Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/baseline-contract.md` and `references/stitched-full-page-capture.md`).
It sits in Testing & QA, covering Visual regression testing. The repository describes itself as: Codex-first Agent Skills library for premium frontend, website, motion, accessibility, QA, and handoff workflows. The licence is MIT.
When your agent uses it
- Tasks that involve Visual regression testing
Example prompts
- “/visual-regression-lab”
Requirements
- Node.js
Workflow steps
9 steps, taken from the first numbered list in SKILL.md.
- Start or identify the local server.
- Open the relevant route in a browser or Playwright.
- Capture the relevant supported viewports and states, using the same conditions for baseline and candidate.
- Check console errors, failed requests, layout overflow, missing media, and text clipping.
- Inspect first viewport composition, hierarchy, spacing, typography, image crops, and CTA visibility.
- Test key interactions: nav, forms, menus, tabs, accordions, hover states, focus states, and modals.
- For animation-heavy work, test reduced-motion behavior and watch for jank.
- For canvas/WebGL/video, verify nonblank rendered pixels and stable framing.
- Report observed differences with evidence. Repair only when authorized, then recapture affected states; no fixed polish-pass or edit quota…
What it can do on your machine
Read from SKILL.md and the folder at commit feff772. 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
Ships 2 files in scripts/ (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
node
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
Visual Regression Lab loads about 516 tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 17 tokens; SKILL.md has 244 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); the scripts in this folder are not scanned.

Visual Regression Lab
Use this skill to capture comparable browser evidence and inspect visual regressions. Scope routes, viewports and states to the requested comparison; a capture alone does not prove quality.
Required Checks
- Start or identify the local server.
- Open the relevant route in a browser or Playwright.
- Capture the relevant supported viewports and states, using the same conditions for baseline and candidate.
- Check console errors, failed requests, layout overflow, missing media, and text clipping.
- Inspect first viewport composition, hierarchy, spacing, typography, image crops, and CTA visibility.
- Test key interactions: nav, forms, menus, tabs, accordions, hover states, focus states, and modals.
- For animation-heavy work, test reduced-motion behavior and watch for jank.
- For canvas/WebGL/video, verify nonblank rendered pixels and stable framing.
- Report observed differences with evidence. Repair only when authorized, then recapture affected states; no fixed polish-pass or edit quota applies.
Read baseline contract. When a project has Playwright installed, run node "<skill-root>/scripts/capture-settled-baseline.mjs" <url> <output-dir> to capture settled desktop/mobile/reduced-motion states and a machine-readable inspection manifest.
When native full-page capture is blank, sparse, incomplete, or inconsistent with real scrolling, read stitched full-page capture and run node "<skill-root>/scripts/capture-stitched-full-page.mjs" --url <url> --output <image>. Treat the stitched image as evidence only after visual inspection.
Output
Report:
- routes/viewports checked
- screenshots or saved paths when available
- issues found and fixed
- commands run
- anything not tested
Resolve <skill-root> to this skill folder's actual absolute location; preserve project-local module resolution for Node capture tools.
