Caveat verdict

88
🟢 Trusted
No high-risk patterns surfaced by the deep scan — automated capability review, not behavioral proof.

Installs packages AND executes processes

Mermaid workflow creating .mmd files, converting to PNG via mmdc CLI, and inserting into Markdown; entirely local file operations with no network or credential 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

Permission integrity

Installs packages at runtime — transitive dependencies are not auditable

Why the tier is capped

Execution sink present in raw bytes (Hard Floor: class B/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.
