The Agent Skills Directory

[SAFE]: The skill implements the Schnorr identification protocol and Zero-Knowledge Password Proof (ZKPP) using established cryptographic standards such as RFC 8235.
[SAFE]: Secure random number generation is handled via the Python secrets module, and password derivation utilizes hashlib.pbkdf2_hmac with a high iteration count (100,000), following security best practices for credential management.
[SAFE]: External references target well-known and trusted academic and technical sources including the RFC Editor, official Python Documentation, and repositories of recognized organizations like Ethereum and the Python Cryptographic Authority.
[INDIRECT_PROMPT_INJECTION]: The scripts/agent.py script accepts user-supplied passwords via command-line arguments to demonstrate the authentication workflow.
Ingestion points: User-provided password string via argparse in scripts/agent.py action handlers.
Boundary markers: Input is handled as a standard string argument for internal cryptographic processing.
Capability inventory: The script performs local file writes (json.dump) to save a report of the protocol demonstration.
Sanitization: Password input is immediately processed through PBKDF2-HMAC-SHA256 before being converted into a numeric secret for cryptographic proofs.
