- Gen Agent Trust Hubpass
The skill facilitates local browser automation using the Chrome DevTools Protocol (CDP) via custom Node.js helper scripts. A low severity issue is identified because the skill provides a generic mechanism (`eval.cjs`) to execute arbitrary JavaScript code within the context of an open browser session, which could be abused under malicious constraints or indirect prompt injections.

Minimal Chrome DevTools Protocol (CDP) helpers for browser automation without MCP server setup.

Install dependencies before first use:
npm install --prefix ~/.claude/skills/browser/browser ws
Scripts
All scripts connect to Chrome on localhost:9222.
start.js - Launch Chrome
scripts/start.js # Fresh profile
scripts/start.js --profile # Use persistent profile (keeps cookies/auth)
nav.js - Navigate
scripts/nav.js https://example.com # Navigate current tab
scripts/nav.js https://example.com --new # Open in new tab
eval.js - Execute JavaScript
scripts/eval.js 'document.title'
scripts/eval.js '(() => { const x = 1; return x + 1; })()'
Use single expressions or IIFE for multiple statements.
screenshot.js - Capture Screenshot
scripts/screenshot.js
Returns { path, filename } of saved PNG in temp directory.
pick.js - Visual Element Picker
scripts/pick.js "Click the submit button"
Returns element metadata: tag, id, classes, text, href, selector, rect.
Workflow
- Launch Chrome:
scripts/start.js --profilefor authenticated sessions - Navigate:
scripts/nav.js <url> - Inspect:
scripts/eval.js 'document.querySelector(...)' - Capture:
scripts/screenshot.jsorscripts/pick.js - Return gathered data
Key Points
- All operations run locally - credentials never leave the machine
- Use
--profileflag to preserve cookies and auth tokens - Scripts return structured JSON for agent consumption
