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 | $0.00960 | $0.00960 |
| Opus 5.5 | $0.00384 | $0.00384 |
| Sonnet 5.5 | $0.00192 | $0.00192 |
| Haiku 4.5 | $0.00096 | $0.00096 |
Grade A, and why
claude-codex-subagent AGENTS.md 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 2mo 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 — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
claude-codex-subagent Agent Rules
This repository packages a Claude Code skill that teaches Claude to delegate
expensive work to local codex exec. The job of every agent in this repo is to
keep that delegation workflow accurate, current, and directly runnable.

Codex CLI Baseline
Target Codex CLI 0.141.0 or newer.
- Prefer
--sandbox workspace-writefor normal local repo work. - Do not introduce new
--full-autoexamples. It is a deprecated compatibility alias; scripts may acceptfull-autoas a user-facing alias only if they emit--sandbox workspace-write. - Use
--dangerously-bypass-approvals-and-sandboxonly for tasks that truly need shell network, cross-workspace access, global installs, or as a documented Windows sandbox fallback. - Use helper
--searchfor current public web facts when shell network is not needed; directcodex execuses--config web_search="live". - Use
--json,-o/--output-last-message, and--output-schemawhen the result is consumed by automation. - Keep
--skip-git-repo-checkin allcodex execexamples and wrappers. - Treat resume as a separate parameter surface:
--cd,--profile,--add-dir, and non-bypass--sandboxare fresh-session context flags and should be rejected by the helper on--resume;--model,--config,--json,-o,--output-schema,--ephemeral, and explicit bypass are resume-time controls in Codex CLI 0.141.0.
Editing Rules
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.
