The Agent Skills Directory

[SAFE]: The skill implements standard cryptographic operations using well-known, trusted libraries. No security issues were identified during the analysis.
Key generation and management: The scripts/agent.py and scripts/process.py scripts facilitate secure Ed25519 key pair generation. process.py appropriately supports passphrase-protected private keys using BestAvailableEncryption.
Cryptographic library usage: The implementation relies exclusively on the cryptography.hazmat primitives, which is the recommended practice for Python-based cryptographic tooling.
Data handling: The skill performs local file operations (reading artifacts and writing signatures) based on explicit command-line arguments. There are no network operations, hardcoded secrets, or obfuscated code patterns.
Documentation: The provided references (references/standards.md, references/workflows.md) point to authoritative sources such as RFC 8032 and NIST FIPS 186-5.
