Caveat verdict
code-share
The skill could potentially exfiltrate data through GitHub Gist, but there is no clear evidence.
โ Flagged for review โ coarse, uncorroborated signal, not a confirmed exploit. Review the config yourself before installing.
Automated static analysis โ not a human review. Caveat flags capabilities, not confirmed intent, and can produce false positives. Disagree with this verdict? Use Dispute below.

Instruction-prose smuggling shape detected: collects a sensitive target ("secret") and emits it outward ("paste"). Phrased as prose with no trigger tokens โ a semantic prompt-injection / data-exfil pattern the syntactic scanners can't see. Final tier capped at Caution; review the instructions before installing.

Why the tier is capped
Execution sink present in raw bytes (Hard Floor: class A). Final tier capped at Caution โ cannot be lifted by any downgrade, example-payload opt-in, or allowlist.
Permissions & capabilities
No declared permissions โ minimal attack surface.
Is this flag fair?
Thanks โ recorded.
