Caveat verdict
one-skill-to-rule-them-all
Accesses system credential store AND makes external network calls
Security analysis skill for auditing other SKILL.md files; the content describes a legitimate defensive tool that identifies prompt injection patterns, with no actual malicious instructions present.
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.

Accesses AWS credentials file

Pipe-to-shell pattern (curl | sh) — supply chain attack vector

Pipe to bash — executes piped content as shell commands

Accesses sensitive system files

Prompt injection — tries to override agent instructions

Accesses .ssh directory

Accesses cloud provider credentials
SKILL.md · code · ~/.aws
References sudo — requests elevated privileges

Instruction-prose smuggling shape detected: collects a sensitive target (".aws") and emits it outward ("POST"). Phrased as prose with no trigger tokens — 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/B). 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.
