Audit Log
An audit log is a tamper-resistant, time-stamped record of actions taken in a system — who did what and when — kept for security, compliance, and troubleshooting.
For AI agents, an audit log captures the actions an agent took and the tools it called, providing accountability and the evidence needed to investigate incidents.
Complete, append-only logging supports governance and is often required to meet security frameworks like SOC 2 and ISO/IEC 27001.
