Caveat verdict

🟢 Trusted
No high-risk patterns surfaced by the deep scan — automated capability review, not behavioral proof.

Writes files AND executes processes

Documentation skill for Cloudflare's Sandbox SDK for building isolated code execution environments; all code examples use official Cloudflare packages and APIs with no malicious patterns.

Automated static analysis — not a human review. Caveat 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 Caveat detects co-occurrence — it does not verify that one flows into another. Read the code to confirm a live chain.

Capability combination critical

Writes files AND executes processes — may drop and execute malicious scripts

LLM05 · LLM06 · ASI05

Capability combination high

Installs packages AND executes processes — opaque dependency chain with execution

LLM03 · ASI04

Capability combination medium

Both reads and writes files — verify scope is limited to intended directories

LLM06 · ASI02

Permission integrity

Installs packages at runtime — transitive dependencies are not auditable

package_install

Findings (3)

Pattern match critical

Recursive delete from root or home — destructive command

SKILL.md · code · rm -rf /

Pattern match high

Uses exec() — may execute shell commands

SKILL.md · code · exec(

Pattern match high

apt-get install — installs system packages

SKILL.md · code · apt-get install

Permissions & capabilities

No declared permissions — minimal attack surface.
