Audit Trails for Agents
What are Audit Trails?
Audit Trail: Complete record of all agent actions, decisions, and interactions for accountability, debugging, and compliance.
Why Audit Trails Matter
Debugging: "Why did agent do X?"
Compliance: "What data did agent access?"
Security: "Did agent misuse tools?"
Improvement: "Where does agent fail?"
Trust: "Can we explain agent behavior?"
