Create a closed feedback loop: Chrome DevTools for agents

on YouTube ↗33m

" summary

Chrome DevTools for agents is an NPM package that lets a coding agent open a real Chrome via MCP server and CLI, inspect runtime network/Console data, and edit code end‑to‑end using Puppeteer as the Puppeteer foundation. Demonstrations include fixing a signup error by reading network responses, shrinking a toggle to 0 bytes of JavaScript and 2.6KB of assets, persisting agent actions to runnable CLI scripts, and a partner case that achieves a 10× efficiency gain by creating 14 specialized skills. Security defaults to anonymous profiles and no access to Chrome password manager.
