Player-YN/BrowserKitten

爪爪 · 完全解放版 (PawWork_ZhuaZhua) is a Chrome MV3 unpacked extension. It runs a side-panel agent that can drive the current tab (action), execute guest JS against the browser (sys inside run), and keep sheet / Univer doc / site HTML artifacts in the session.

Not on the Chrome Web Store. No hosted model — bring your own key.

Load it

1. Clone this repo, or download a Release zip 2. Chrome → chrome://extensions → Developer mode → Load unpacked → select the folder (manifest.json is at its root) 3. Open the side panel → paste an OpenAI-compatible API key (BYOK; stored in chrome.storage.local) → send a task on a normal http(s) page

After editing files, click 重新加载 on the extension card. There is no package.json and no build step.

Needs Chrome 135+. On Chrome 138+, enable Allow User Scripts on the extension details page if you want sys.eval or page-identity fetch. Close DevTools on the target tab before using sys.cdp (otherwise CDP_BUSY). Restricted pages such as chrome:// and the Web Store return NEED_PAGE.

Tests

node --test tests/runtime-regression.test.mjs      # pure Node, no browser
node tests/browser-smoke.cjs   # loads the real extension

Architecture
