The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill references the installation of the standard Python cryptography library for its operations.
Evidence: pip install cryptography>=41.0 in references/api-reference.md and scripts/process.py.
[SAFE]: The implementation in scripts/agent.py and scripts/process.py utilizes the well-known cryptography library to handle X25519 key exchange, HKDF key derivation, and AES-256-GCM encryption. No patterns of credential theft, obfuscation, or unauthorized remote code execution were found.
[SAFE]: The skill maintains a legitimate purpose as a security implementation guide, and its use of external links is limited to official RFCs, NIST standards, and Signal Protocol specifications.
