Claude

Claude Code loads skills from ~/.claude/skills/ (all projects) or .claude/skills/ (one project):

git clone --depth 1 https://github.com/liarjsdev/liarjs-skills.git
cp -r liarjs-skills/skills/playwright-stealth-verify ~/.claude/skills/playwright-stealth-verify   # personal, or .claude/skills in a project

In the Claude apps, zip the playwright-stealth-verify folder and upload it under Customize > Skills > + > Upload a skill (code execution must be on).

ChatGPT / Codex

Codex reads skills from .agents/skills/ in a repo or ~/.agents/skills/ for every project:

git clone --depth 1 https://github.com/liarjsdev/liarjs-skills.git
cp -r liarjs-skills/skills/playwright-stealth-verify .agents/skills/playwright-stealth-verify   # repo; ~/.agents/skills for all projects

Standalone skills also load in the ChatGPT desktop app.

What this skill does

Check whether a Playwright, Puppeteer, Selenium or CDP-driven browser presents a coherent fingerprint, using liarjs as a library against a Page you already have - navigator.webdriver, HeadlessChrome tokens, worker versus main-thread identity, patched-API integrity, WebGL versus WebGPU GPU identity.

When it triggers

  • Use when asked whether an automated browser looks like a normal one, when a headless setup or a stealth plugin's effect needs measuring rather than assuming, or when an assertion on fingerprint quality belongs in a test suite.
