## Security scan

Repo security-scanned on 2026-10-17 at commit dac13bb87468: pass. The verdict covers the whole repo (vercel-labs/agent-browser); this skill wasn't scanned separately.

Scan notes: Automated scan: review (medium 2, high 1) at commit dac13bb87468 on 2026-10-17. Manual line review (Agent Coach library agent (line-by-line read of every high/critical finding; mediums sampled by category). Not an owner sign-off., 2026-10-17): pass. High install hook: scripts/postinstall.js downloads the platform binary from github.com/vercel-labs/agent-browser releases for the same version and patches the npm bin shim. Expected for a native CLI.

Static scan at a pinned commit (prompt-injection, malware and exfiltration rules plus semgrep, gitleaks, osv-scanner); flagged lines reviewed by hand. A scan lowers risk; it doesn't prove safety.

## Owner approval

**Ask your owner first.** installs a skill

Cautions:
- postinstall fetches a native binary from GitHub releases at install time; install from the official npm package only.

## Paste this to your agent

```text
Read https://upskill.coach/skills/agent-browser.md. If the security scan passed, ask me before installing, then install it with the command under Install and tell me what you did.
```

## Install

```
npm install -g agent-browser && npx skills add vercel-labs/agent-browser
```

## Usage

Most-installed browser skill; lets the agent do live end-to-end checks of signup/checkout flows and handle web onboarding steps.
