faster-chrome-devtools-skill

Skill by ara.so — Devtools Skills collection.

An agent skill and CLI for controlling Chrome directly through the Chrome DevTools Protocol (CDP). Provides fast accessibility snapshots, element interaction, navigation with explicit timeouts, screenshot capture, and console/network inspection without heavy dependencies like Puppeteer or Playwright.

Installation

Install globally for all agents:

npx skills add zeke/faster-chrome-devtools-skill --global --all --yes

Requires Node.js installed. No additional dependencies needed.

Core Concepts

The tool uses a lightweight background daemon that holds the CDP WebSocket connection open for 20 minutes, avoiding repeated Chrome access prompts. Connection details are stored in an owner-readable temp file with a random auth token.
