Caveat verdict

Writes files AND executes processes
Skill install guardian that inspects third-party skills for security risks before installation; purely instructional with red-flag detection guidance and no malicious behavior in the content itself.
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.
Writes files AND executes processes — may drop and execute malicious scripts
LLM05 · LLM06 · ASI05
Reads files AND uses eval/Function — may execute locally stored payloads
LLM05 · LLM06 · ASI05
Installs packages AND executes processes — opaque dependency chain with execution
LLM03 · ASI04
Both reads and writes files — verify scope is limited to intended directories

Why the tier is capped
Execution sink present in raw bytes (Hard Floor: class A/B/C/D/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.
