🟠 Risky
Significant risk patterns flagged — automated deep scan, not behavioral proof.

Installs packages AND executes processes

The skill automates file downloads from dynamic webpages. While useful, executionSinkDetected=true and package installation raise concerns.

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 high

Installs packages AND executes processes — opaque dependency chain with execution

LLM03 · ASI04

Permission integrity

Installs packages at runtime — transitive dependencies are not auditable

Pattern match high

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.
