What it does
Visual Test is an agent skill from LiberatedPixelCup/Universal-LPC-Spritesheet-Character-Generator. Run or add Playwright visual specs and know when a layout or CSS change needs npm run test:visual. Use after first-paint, panel-layout, or PurgeCSS safelist changes, or when adding a Playwright case.
Its SKILL.md is about 280 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA, covering Browser testing. It works with Playwright and npm. The repository describes itself as: Character Generator based on Universal-LPC-Spritesheet. The licence is GPL-3.0.
When your agent uses it
- Tasks that involve Browser testing
Example prompts
- “/visual-test”
Requirements
- A credential in ARGOS_TOKEN
What it can do on your machine
Read from SKILL.md and the folder at commit 58ce1aa. 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
Shell commands in SKILL.md call:
npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
ARGOS_TOKEN
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Visual Test loads about 282 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 69 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.
SKILL.md
The full file from LiberatedPixelCup/Universal-LPC-Spritesheet-Character-Generator at commit 58ce1aa, republished under its GPL-3.0 licence (© LiberatedPixelCup). 69 words, ~282 tokens.

Visual tests
Run npm run test:visual after a change that affects first paint, panel
layout, or a class in
vite/purgecss-critical-safelist.ts.
Add cases under tests/visual/. Reuse waits in
home-helpers.ts. Wait for catalog
readiness via __LPC_waitCatalogAllReady (installed in
sources/install-item-metadata.ts). Do not import visual specs
from tests/tests.js. They are not Codecov-instrumented.
Argos upload needs ARGOS_TOKEN. Isolated run:

Visual regression tests.
CLS measurement is cls / CLS.md; Argos
does not replace profile:cls.
