anti-detect-browser skills are trending and deserve a safety check before install: why it is not safe to use

What happened

The skills.sh trending page currently shows several third party skills with names tied to anti detect browser use: `browser-mcp-agent`, `anti-detect-browser`, and `multi-account-isolation`. Each appears at roughly 1.3K installs in the last 24 hours. These are not built in Claude or Codex features.

Based on their names, these skills appear meant to help an agent use a browser with fingerprinting or account isolation tactics. Fingerprinting is the set of signals a website uses to recognize a browser or device. Account isolation means keeping separate accounts or sessions apart.

skills.sh says it performs routine audits, but its documentation also says it cannot guarantee the security of every listed skill and advises users to review skills before installing them.

What it means for you

For a normal person using an AI agent, the main concern is not the trend itself. It is access. A browser automation skill may be able to see or use logged in sessions, cookies, web clicks, and steps inside sensitive account workflows.

That can matter if you use an agent for email, banking, admin panels, shopping, or any account with saved payment or personal data.

What to do instead

Before installing any third party browser skill, read its page, check who published it, and look for a clear explanation of what data and permissions it needs.

Use a separate browser profile or test account when possible. Avoid connecting high value accounts unless you fully trust the skill. Remove skills you do not use.

If you want a narrower starting point, AgentPod lists only reviewed, tested skills. That does not remove all risk, but it can help reduce guesswork.
