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.

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 | $0.00067 | $0.05193 |
| Opus 5 | $0.00034 | $0.02596 |
| Sonnet 5 | $0.00013 | $0.01039 |
| Haiku 4.5 | $0.00007 | $0.00519 |
Grade A, and why
codex-supervision scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to codex-supervision — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 392 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codex Supervision
Hand work to the local codex CLI and supervise the result — read what Codex actually did, inspect artifacts, verify claims, only then answer the user.
Supervision, not blind delegation.
This skill exists because the official openai/codex-plugin-cc is a Claude Code plugin, and Claude Desktop (consumer chat client) does not load plugins. The skill provides the essential capability via PowerShell wrapper scripts the model invokes through its shell tool.
Requirements
- PowerShell 7+ (
pwsh.exe). UsesProcessStartInfo.ArgumentListandProcess.Kill(bool)which are .NET Core 3+ only — Windows PowerShell 5.1 will not work.codex-setup.ps1reports the detected version and refuses to markready=trueon older hosts. - Node.js 18.18+ (codex CLI requirement)
codexCLI 0.128+ on PATH, at$env:CODEX_PATH, or at%USERPROFILE%\bin\codex.cmd- A ChatGPT subscription or OpenAI API key for codex authentication
What this skill provides
PowerShell scripts under scripts/:
common.ps1— codex resolution, env hygiene, async I/O, timeout, artifact capturecodex-setup.ps1— verify codex CLI version + login + writable state dircodex-review.ps1— non-interactive code review (normal or adversarial) viacodex exec reviewcodex-task.ps1— delegate an arbitrary task to codex (rescue equivalent)codex-list-sessions.ps1— inspect prior runs
These scripts:
- require a locally installed
codexCLI on PATH, at$env:CODEX_PATH, or at%USERPROFILE%\bin\codex.cmd - read/write UTF-8; set
Console.OutputEncodingto UTF-8 to survive Chinese-locale Windows - run codex non-interactively (
codex exec/codex exec review) with async stdout/stderr reads — no pipe-buffer deadlock - enforce a
-TimeoutSecand kill codex if it hangs - pass
-Base/-Uncommitted/-Titlethrough to the native review subcommand (codex does the git diff scoping itself) - default to
read-onlysandbox; only escalate toworkspace-writewith-Write, ordanger-full-accesswith-DangerousFullAccess - always write
last-prompt.txt,last-response.txt,stderr.log,session.jsonto the session dir
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-supervision is a skill published in the GitHub repository ltczding-gif/agent-supervision-skills (2 stars, last pushed 3mo ago), licensed MIT. It adds 67 tokens to every session and 5,193 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings.

codex-supervision
Use when the user wants Claude to delegate work to the local Codex CLI — code review, adversarial review, or substantive rescue tasks — and then independently verify what Codex did. Works in Claude Desktop (no plugin system required); wraps codex exec as PowerShell scripts and keeps run artifacts on disk.
