callkit-voip

The skill's footprint is coherent with its stated purpose of implementing CallKit/PushKit VoIP functionality. It uses official Apple frameworks, standard token handling, and a Call Directory extension pattern appropriate for caller ID/blocking. There are no evident supply-chain or credential-exfiltration patterns, and no unverifiable binaries are involved. Overall risk is low-to-moderate (securityRisk ~0.55) with minimal malware risk (malware ~0.05). The design appears proportionate to its goal, though thorough review of server-side token handling and extension data management would be prudent in a real-world deployment.
