Codex Agent Audit

Last updated: 2026-09-24

Short answer: A coding agent audit should preserve tool call history, session records, file or command context, receipts, and the evidence needed to check whether the requested change actually occurred. An install page is not an audit record.

Before the session

Define the task, permitted files, commands, and evidence needed for acceptance.

During the session

Preserve tool calls, observed outputs, timestamps, failures, and approval boundaries.

After the session

Open the relevant receipts, verify their integrity, inspect the final state, and distinguish a reported change from a confirmed change.

Live verification example

Open a public execution receipt or call its verifier. The example reports verification_status: verified for the stored record. It is not proof of an unobserved external outcome.

Frequently asked questions

Codex agent audit

A coding agent audit should preserve tool call history, session records, file or command context, receipts, and the evidence needed to check whether the requested change actually occurred. An install page is not an audit record.

What can a verifiable receipt prove?

It can show what the execution layer recorded and what its integrity checks verify. It cannot prove an unobserved outside outcome.

How can another reviewer check the record?

Open the public receipt, compare the tool, time, result, and status, then call the verifier. Keep outside confirmations separate from the execution record.
