Adds an example showing how to Ed25519-sign every CrewAI tool call with
Signet, producing a tamper-evident audit trail.

What it does

  • Signs every tool call with Ed25519
  • Appends to SHA-256 hash-chained audit log
  • 3-line integration via install_hooks()
  • Offline verification with signet audit --verify

Files

  • README.md — setup, usage, explanation
  • main.py — working example with two agents and two tools
  • requirements.txt — crewai + signet-auth

Why this matters

AI agents need audit trails for compliance and incident response.
This integration adds cryptographic proof of every tool invocation
without changing existing agent code.
