Caveat verdict
tunnel-proxy
Reads local files AND makes external network calls
The skill explicitly self-identifies as a 'RAT (Remote Access Trojan)', provides a PTY shell for arbitrary remote command execution, bidirectional file transfer, and HTTP reverse proxy — the description warns it can 'install backdoors, turn your PC into a botnet node' — this is a concrete remote code execution backdoor regardless of user consent framing.
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.
Reads local files AND makes external network calls — the capabilities for data exfiltration co-occur (data-flow not verified)

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