A browser-control connection that lets an AI agent operate a real, logged-in Chrome browser using clicks, drags, and keystrokes. It checks what is under the pointer before clicking to avoid overlays and fixed page bars.

It helps automate browser tasks that require visible interaction, such as clicking, dragging, and typing in Chrome.

It lets the agent work in the browser session you already use, including sites where you are logged in. Hit-testing helps prevent clicks from landing on an obstruction instead of the intended control.

chromeboost — Plugin for Gemini CLI by lordamdal

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/lordamdal/chromeboost

Made for: Gemini CLI.

Security

Grade A, and why

chromeboost scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
