call-fraud-shield skillA

call-fraud-shield is agent-read markdown (skill) from calle-ai/awesome-phone-call-agents: Post-call fraud detection skill. Analyses a CALL-E transcript for vishing, spam, social engineering, and scam-script patterns using conversational trajectory analysis and a curated scam archetype library. Returns a structured risk card with XAI-explained evidence spans, threat category classification, an escalation-direction assessment, and a recommended action. Grounded in peer-reviewed vishing-detection and adversarial-evasion research (arXiv:2502.03964, arXiv:2609.07151, arXiv:2507.16291)..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
