Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00051 | $0.01889 |
| Opus 5 | $0.00026 | $0.00945 |
| Sonnet 5 | $0.00010 | $0.00378 |
| Haiku 4.5 | $0.00005 | $0.00189 |
Grade A, and why
codex-review-gate 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 9d 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 — 178 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codex Review Gate
Use this gate after implementation and local verification. Dispatch reviews only through the local gtwy stdio MCP server, never through a direct codex CLI command. In Codex the gateway tools normally have names such as mcp__gtwy__codex_request and mcp__gtwy__codex_request_async; some clients show their short names instead.
Non-Negotiable Review Rules
- Omit model unless the user selected one.
- Pass approvalStrategy: "legacy". Codex cannot use mcp_managed, and approvalPolicy has no effect for it.
- Use sandboxMode: "read-only" for an inspection-only review. Use sandboxMode: "workspace-write" only when the reviewer needs to create build or test artifacts. Do not use fullAuto; it is deprecated shorthand for workspace-write.
- Require this exact terminal JSON verdict:
APPROVED_UNCONDITIONALLY,CHANGES_REQUIRED, orBLOCKED_EXTERNAL. - Do not impose a review-round, turn, token, price, cost, or wallclock cap. Do not use a provider equivalent of those controls to shorten a mandatory review. The configured idle-timeout safeguard only detects a process that stops producing output.
- Accept only explicit, evidence-backed
APPROVED_UNCONDITIONALLY. Conditional approval, residual findings, a malformed verdict, inability to verify, cancellation, timeout, or provider error does not pass the gate.
Keep fixing and re-reviewing until the required verdict arrives. Stop only on
explicit user cancellation or a terminal external provider failure. A terminal
failure is BLOCKED_EXTERNAL with its exact error, never permission to skip the gate.
Explicit user-authorized full-access override
The normal safe posture above does not apply when the user explicitly grants
full provider permissions and native MCP access for this review. Build the
target checkout and start node dist/index.js --transport=stdio from that
checkout. Do not call a global or stale gtwy process. On a fresh Codex session
use approvalStrategy:"legacy", sandboxMode:"danger-full-access", and
dangerouslyBypassApprovalsAndSandbox:true.
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.

codex-review-gate is a skill published in the GitHub repository verivus-oss/llm-cli-gateway (15 stars, last pushed yesterday), licensed MIT. It adds 51 tokens to every session and 1,889 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
