ClawAudit verdict

🟢 Trusted
Low risk — reviewed by ClawAudit, behavior matches stated purpose

Encodes data AND uses eval

Local Python calculator using numpy/scipy/mpmath to evaluate user-supplied mathematical expressions; dynamic_eval is the documented eval subcommand for math, not arbitrary code injection, and there is no network exfiltration.

Automated static analysis — not a human review. ClawAudit 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 ClawAudit detects co-occurrence — it does not verify that one flows into another. Read the code to confirm a live chain.

Capability combination critical

Encodes data AND uses eval — the obfuscated-execution pattern (atob + eval; data-flow not verified)

Why the tier is capped

Execution sink present in raw bytes (Hard Floor: class D). Final tier capped at Caution — cannot be lifted by any downgrade, example-payload opt-in, or allowlist.
