Agent Browser Qw

Security checks across static analysis, malware telemetry, and agentic risk

Overview

This looks like a legitimate browser automation wrapper, but it exposes browser cookies, localStorage, and credentials without clear scope or safeguards.

Install only if you need agent-driven browser automation. Verify the external agent-browser package first, use a separate browser profile or test account, and do not allow the agent to access cookies, storage, credentials, uploads, or live account actions without explicit approval.

Risk analysis

Artifact-based informational review of SKILL.md, metadata, install specs, static scan signals, and capability signals. ClawScan does not execute the skill or run runtime probes.

What this means

An agent using this skill could read or alter session data for sites opened in the automated browser, which may affect logged-in accounts.

Why it was flagged

These commands can expose or modify browser session state that may contain authentication cookies, tokens, or account data, and the artifact does not define which domains/profiles are in scope or require confirmation before use.

Skill content
agent-browser cookies                     # Get all cookies
agent-browser cookies set name value      # Set cookie
agent-browser cookies clear               # Clear cookies
agent-browser storage local               # Get all localStorage
Recommendation

Use an isolated browser profile or test account, avoid sensitive logged-in sessions, and require explicit user approval before cookie, storage, credential, or header commands.

What this means

Poorly scoped tasks could cause unwanted clicks, submissions, or file uploads on websites.

Why it was flagged

The skill exposes browser actions that can submit forms or upload user-selected files. This is aligned with browser automation, but it can have real effects on websites if used on live accounts.

Skill content
agent-browser click @e1           # Click
agent-browser fill @e2 "text"     # Clear and type
agent-browser upload @e1 file.pdf # Upload files
Recommendation

Supervise use on important accounts, prefer test environments, and confirm before submissions, purchases, posts, or uploads.

What this means

The safety of the installed CLI depends on the external package and its current dependency chain, not just this skill file.

Why it was flagged

The skill is instruction-only and relies on installing an external, unpinned npm CLI and its browser dependencies, so the actual executable code is not present in the reviewed artifact set.

Skill content
npm install -g agent-browser
agent-browser install
agent-browser install --with-deps
Recommendation

Verify the npm package and upstream repository, consider pinning a known-good version, and install in a controlled environment.
