Drive the user's dedicated Chrome AI window with the dev-browser CLI to open sites, click, fill forms, read pages, take screenshots and check a live app while signed in. Use when the user says browse, open a site, click, fill a form, screenshot, scrape, test my site, or check something on the web.
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
Do every browser task in Chrome AI, the user's dedicated Chrome window (profile `~/.chrome-ai-profile`, port 9333) where they are already signed in to their tools. Start it first (it does nothing if it is already open), then connect to it on every run:
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/dev-browser/<path> -o <scratch>/<file>` (for example `references/api-reference.md`), 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`.
```bash
chrome-ai start
dev-browser --connect http://127.0.0.1:9333 <<'JS'
const page = await browser.getPage("stripe-sales");
await page.goto("https://dashboard.stripe.com");
console.log(JSON.stringify({ title: await page.title(), url: page.url() }));
JS
```

How to install
mdr add melvynx/ai-maxxing-skills/dev-browser@sha256:40f9d28aecabd198The 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.
