The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.

name: web-browser
description: "Allows to interact with web pages by performing actions such as clicking buttons, filling out forms, and navigating links. It works by remote controlling Google Chrome or Chromium browsers using the Chrome DevTools Protocol (CDP). When Claude needs to browse the web, it can use this skill to do so."

# Web Browser Skill
Minimal CDP tools for collaborative site exploration.
## Start Chrome
```bash
./scripts/start.js # Fresh profile
./scripts/start.js --profile # Copy your profile (cookies, logins)
```
Start Chrome on `:9222` with remote debugging.
## Navigate
```bash
./scripts/nav.js https://example.com
./scripts/nav.js https://example.com --new
```
Navigate current tab or open new tab.
## Evaluate JavaScript
```bash
./scripts/eval.js 'document.title'
./scripts/eval.js 'document.querySelectorAll("a").length'
./scripts/eval.js 'JSON.stringify(Array.from(document.querySelectorAll("a")).map(a => ({ text: a.textContent.trim(), href: a.href })).filter(link => !link.href.startsWith("https://")))'
```
Execute JavaScript in active tab (async context). Be careful with string escaping, best to use single quotes.
## Screenshot
```bash
./scripts/screenshot.js
```
Screenshot current viewport, returns temp file path
## Pick Elements
```bash
./scripts/pick.js "Click the submit button"
```
Interactive element picker. Click to select, Cmd/Ctrl+Click for multi-select, Enter to finish.
## Dismiss Cookie Dialogs
```bash
./scripts/dismiss-cookies.js # Accept cookies
./scripts/dismiss-cookies.js --reject # Reject cookies (where possible)
```
Automatically dismisses EU cookie consent dialogs.
Run after navigating to a page:
```bash
./scripts/nav.js https://example.com && ./scripts/dismiss-cookies.js
```
## Background Logging (Console + Errors + Network)
Automatically started by `start.js` and writes JSONL logs to:
```
~/.cache/agent-web/logs/YYYY-MM-DD/<targetId>.jsonl
```
Manually start:
```bash
./scripts/watch.js
```
Tail latest log:
```bash
./scripts/logs-tail.js # dump current log and exit
./scripts/logs-tail.js --follow # keep following
```
Summarize network responses:
```bash
./scripts/net-summary.js

Questions
What does the Web Browser skill do?
High-performance AI coding agent CLI written in Rust with zero unsafe code
Is Web Browser safe to install?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.
What can Web Browser access on my machine?
The audit observed that it reaches the network and runs shell commands. Each of those is consistent with what it says it does. Secrets in the source: none found.
How current is this page?
The grade is for one exact copy of the source (46a2537504c9), read on 2026-10-10. The repository is watched, and a new audit runs when it changes — this is the first audit.
