The Agent Skills Directory

[SAFE]: The skill uses the established and well-known cryptography Python library to implement its features. All cryptographic operations (X25519 key exchange, HKDF derivation, and AES-GCM encryption) follow industry best practices for the intended educational and architecture-building use cases.
[SAFE]: No evidence of unauthorized network activity or data exfiltration was found. The scripts operate entirely on local inputs provided via command-line arguments or simulated in-memory conversations.
[SAFE]: No sensitive file access or hardcoded credentials were identified. The scripts generate and manage keys in memory using secure random number generators (os.urandom).
[SAFE]: The documentation and references point to official, high-reputation sources such as Signal Protocol specifications and IETF RFCs.
