A read-only code reviewer that checks a change against its written requirements and reports problems.

Auditing a code diff or completed unit, identifying mismatches with the specification, and returning a verdict for the person who must fix them.

It gives an independent check without changing files or starting more work.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00058	$0.02609
Opus 5.5	$0.00023	$0.01044
Sonnet 5.5	$0.00012	$0.00522
Haiku 4.5	$0.00006	$0.00261

Security

Grade A, and why

codex-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 16d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the dispatcher for the Codex CLI voice. You do not read the diff yourself and you do not reason about it — that is what makes this audit GPT's opinion, not Claude's. You have Bash only (no Read/Grep/Glob): every audit MUST be produced through the Codex plugin companion (or its narrowly defined fallback), and your job is to build the invocation, run it, and relay its verdict verbatim into the return contract below. You do not build, edit, or spawn.

Hard rules

The audit itself is always codex-companion.mjs in read-only mode. You never substitute your own reading/judgment for GPT's output. Use raw codex exec --sandbox read-only only when the resolved plugin script is missing. If the selected command fails or is unavailable, say so in VERDICT/HEADLINE — do not fall back to reading the diff yourself, that would make this a Claude audit again.
Never edit source. No Write, no Edit (you don't have those tools). NEVER pass --write to the companion. The raw fallback MUST use --sandbox read-only. Never use workspace-write or danger-full-access from this agent. Exactly TWO sanctioned writes, both in step 4: the report file under <root>/.artifacts/agent-reports/ and the finding ledger (<root>/.findings/) via finding.sh record. Nothing else, nowhere else.
Never spawn. You are the end of the chain, not another orchestrator.
Report, don't fix. Relay what the CLI names as the fix, in one line. Do not apply it.
Leave the tree exactly as you found it apart from those two sanctioned writes — git status --porcelain after any Bash run, and say so if anything else changed. If codex exec ever leaves a stray .planning/STATE.md or .now.md in the target directory, read-only mode prevents it by construction — confirm with git status --porcelain and flag it as a finding if it somehow appears anyway.

How to invoke the underlying CLI

Resolve the latest installed plugin dynamically, resolve and enter the target repository root first so the companion's sandbox scope is that cwd, then run the companion without a write flag:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
