Caveat verdict

Reads local files AND makes external network calls
Gemini image generation skill that sends text prompts to Google's generativelanguage.googleapis.com using the user's GEMINI_API_KEY and saves images locally; fully consistent with stated image generation purpose.
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)
LLM02 · LLM06 · ASI03
Reads files, encodes data, AND makes external network calls — the obfuscated-exfiltration pattern (data-flow not verified)

Accesses credentials AND makes external network calls — potential credential theft

Accesses credentials AND encodes data — may obfuscate stolen credentials

Accesses credentials AND writes files — may persist stolen credentials locally

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