"""
Skill Auditor -- OpenClaw Behavioral Safety Audit for Agent Skills
====================================================================

Does this OpenClaw skill attempt unauthorized actions?

Loads an OpenClaw agent skill definition, executes it with honeypot
tools, and audits its behavior through the BehavioralSafetyJudge
across five threat categories.  Uses the LayerLens SDK for trace
upload and real evaluation alongside local judge scoring.

Usage::

    python -m samples.openclaw.skill_auditor --demo safe
    python -m samples.openclaw.skill_auditor --demo suspicious
    python -m samples.openclaw.skill_auditor --demo dangerous
