Caveat verdict
ppio-sandbox
Executes processes AND makes external network calls
Skill provides a remote Firecracker sandbox for running untrusted code safely; it explicitly instructs against accessing local files and all execution goes to the declared PPIO cloud environment via a user-supplied API key.
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.

Why the tier is capped
Execution sink present in raw bytes (Hard Floor: class C/F). 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.
