ClawAudit verdict

fast-agent-browser

88
🟢 Trusted
Low risk — reviewed by ClawAudit, behavior matches stated purpose

Reads files AND uses eval/Function

A legitimate browser automation CLI using Playwright; the dynamic_eval and executionSinkDetected flags correspond to documented JavaScript execution capability used for browser interaction, which is the stated and expected purpose of a browser automation tool.

Automated static analysis — not a human review. ClawAudit flags capabilities, not confirmed intent, and can produce false positives. Disagree with this verdict? Use Dispute below.

What it does

These are capability combinations: each listed behavior occurs in the skill, but ClawAudit detects co-occurrence — it does not verify that one flows into another. Read the code to confirm a live chain.

Capability combination critical

Reads files AND uses eval/Function — may execute locally stored payloads

Permission integrity

Performs file operations but does not declare file-accessing binaries

file_read

Installs packages at runtime — transitive dependencies are not auditable

Findings (3)

Pattern match high

Uses eval() — can execute arbitrary code

src/browser.py · prose · downgraded · eval(

Pattern match medium

pip3 install — installs Python packages at runtime

SKILL.md · code · pip3 install

Pattern match medium

subprocess execution — runs system commands from Python

Why the tier is capped

Execution sink present in raw bytes (Hard Floor: class D). Final tier capped at Caution — cannot be lifted by any downgrade, example-payload opt-in, or allowlist.

Permissions & capabilities

No declared permissions — minimal attack surface.
