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 | $0.00518 | $0.00518 |
| Opus 5.5 | $0.00207 | $0.00207 |
| Sonnet 5.5 | $0.00104 | $0.00104 |
| Haiku 4.5 | $0.00052 | $0.00052 |
Grade A, and why
codex-third-party-subagents 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 — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Project scope
- Unofficial, macOS-only public beta for Codex Third-Party Subagents
(
codex-third-party-subagents): a provider-pack-based Codex Desktop fallback routing stack. - Text, code, research synthesis, and local validation only. No image, audio, video, desktop, or browser handling. DeepSeek V4 Pro is explicit-only: never auto-route to it or broaden its controlled maintainer runtime evidence into a public-installer, independent-user, or general support claim.
- Node.js
>=20, standard library only. No third-party runtime dependencies.
Rules for agents working here
- Do not hardcode, commit, or log secrets. API keys live in the macOS Keychain and are read at runtime only.
- Do not execute any official provider setup script. Catalog data is retrieved at install time as inert text (documented, never executed) with a local catalog-source override; do not vendor official catalog or prompt files.
- CLI changes must keep dry-run as the default; writes require an explicit
--apply. - Custom Agent identity comes from the official TOML
namefield in~/.codex/agents; routing policy must not be documented as Host registration. - The task bridge allows exactly one active provider task. Active slot and task
file are owner-only (
0700/0600), reject symlinks, and are atomically archived tocompleted-*orfailed-*. Never overwrite or delete archives. - Desktop preflight is a policy-assisted guardrail, not guaranteed native automatic interception. Document it as defense-in-depth.
- Preserve unrelated local changes. Make minimal, scoped diffs.
- Keep files small: JS/TS under 300 lines, docs concise.
- Update
docs/current-state.mdanddocs/tasks.mdon durable changes. Documented capabilities must match the implementation. - GitHub Actions workflows must use read-only permissions and no secrets.

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.
