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 | $0.00352 | $0.00352 |
| Opus 5 | $0.00176 | $0.00176 |
| Sonnet 5 | $0.00070 | $0.00070 |
| Haiku 4.5 | $0.00035 | $0.00035 |
Grade A, and why
codex-oss-maintainer-toolkit 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 8d 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.
What it actually says
AGENTS.md
Mission
This repository is a Codex-first toolkit for open-source maintainers. Keep the repo aligned with Codex terminology, AGENTS.md conventions, reusable skills, and maintainer automation workflows.
Repository Map
SKILL.md: the primary Codex skill for maintainer workflow design.scripts/: authoring helpers for creating, validating, and packaging skills.references/: reusable patterns for outputs and multi-step workflows.templates/: bootstrap material for Codex projects (AGENTS.md, automation scripts, agent prompts, dev docs, skill catalog).examples/full-project/: example repository layout after bootstrapping.demo/: marketing/demo pages that should stay consistent with the public positioning.
Editing Rules
- Read before editing and keep changes minimal.
- If you change public positioning, update
README.md,README_EN.md,SKILL.md,install.sh, anddemo/in the same turn. - If you change anything in
templates/, sync the same structure inexamples/full-project/. - Prefer Codex/OpenAI terminology. Remove stale vendor-specific references unless they are historical context that is explicitly needed.
- Validate with targeted commands before finishing. At minimum, run the repository search guard and the relevant Python/shell checks.
Default Maintainer Workflow
- Audit the repository and identify maintainer bottlenecks.
- Write or refine
AGENTS.mdclose to the work. - Move repetitive maintainer tasks into skills, references, or automation scripts.
- Add verification commands so contributors can prove changes worked.
- Keep templates, examples, and docs coherent.
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.
