Audit Trail

Record who or what triggered an AI action, what inputs and tools were used, and what changed. Teams can reconstruct decisions for compliance, debugging, and accountability.

Overview

How might we design audit trail so people can trust and act on AI output?

When to use

  • Critical for enterprise applications, regulated industries, and systems where comprehensive audit trails ensure compliance, accountability, and transparency.

When to skip

  • Personal creative sandboxes with no shared accountability need.
  • Throwaway prototypes where retention would create unnecessary privacy risk.
  • Ultra-low-latency edges where logging every token would break the product (sample instead).

Rules

  • Logs that only store model text and omit tool calls or user identity.

  • Audit UIs readable only by engineers, with no product-facing timeline.

  • Immutable claims while still allowing silent admin edits to history.

  • Retaining raw prompts forever with no retention policy or redaction.

FAQ

What belongs in an AI audit trail?

Actor (user or agent), timestamp, model or skill version, inputs or references, tools invoked, outputs or side effects, and any human approval or override.

Who should see the trail?

End users often need a lightweight activity history. Admins and compliance need deeper exportable logs. Do not dump raw secrets into either view.

How is an audit trail different from chain of thought?

Chain of thought explains reasoning for one answer. An audit trail is the durable record of actions across time for accountability.

How long should trails be kept?

Match legal and product needs, then delete or aggregate. Infinite retention of prompts is a privacy liability.
