Set up a dedicated Chrome window for the AI (its own profile, signed in to the user's accounts) and the dev-browser CLI and skill, so the agent can browse, click, fill forms and check sites in it. Use when the user wants to set up dev-browser, a browser for the AI, or Chrome AI.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Give the agent its own Chrome: a separate window with its own profile, where the user signs in once to their tools, and that the agent drives through the `dev-browser` CLI. The user's normal Chrome stays untouched, and the agent never needs a password because the sessions stay saved in that profile. Do every step yourself and only ask for what needs a human (installing Chrome, signing in). Talk to the user in their language, short messages, no jargon (never say "CDP", "profile directory" or "PATH" to them). If you got this skill from a link instead of a local folder, install nothing else from the repo: download a file it links only when a step needs it, with `curl -fsSL https://raw.githubusercontent.com/Melvynx/ai-maxxing-skills/main/skills/setup-dev-browser/<path> -o <scratch>/<file>` (for example `scripts/chrome-ai`), and read another skill it names only when you reach it, from `https://raw.githubusercontent.com/Melvynx/ai-maxxing-skills/main/skills/<skill-name>/SKILL.md`. …

How to install
mdr add melvynx/ai-maxxing-skills/setup-dev-browser@sha256:dc33208191279edbThe line at the top of this page pins the label git:20261021.81ed9c7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
