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 | $0.00654 | $0.00654 |
| Opus 5 | $0.00327 | $0.00327 |
| Sonnet 5 | $0.00131 | $0.00131 |
| Haiku 4.5 | $0.00065 | $0.00065 |
Grade A, and why
book 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 2d 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
🤖 Codex 协作协议 (Codex Collaboration Protocol - CAP)
📌 项目指纹
- 项目名称：Codex 蓝皮书

🤖 Codex Collaboration Protocol (CAP)
📌 Project Signature
- Project Name: Codex Blue Book
- Framework: Markdown Guide / Book Project
- Coding Style: Professional, concise, tech-rich, easy-to-read Chinese with proper formatting and diagrams.
- Reference Style: Links should be absolute paths with
file:///scheme (e.g.[link text](file:///Users/hunkwu/Desktop/ai/book/README.md)).
🎯 Target Audience
- Professional developers looking to leverage AI agents (especially OpenAI Codex) for high-efficiency development.
- Indie Hackers / Entrepreneurs wanting to build commercial-grade MVPs autonomously.
🛑 Hard Constraints
- Do not use placeholders: Always provide real, functional examples and configurations.
- Keep it practical: Every chapter must contain step-by-step code snippets, command executions, or configuration templates.
- Preserve Links: Ensure all links between chapters are correctly referenced.
- No verbose summaries: Avoid repeating contents; focus on actionable insights, mental models, and step-by-step walkthroughs.
🧪 Verification Specs
- All markdown files must be syntactically valid and link to actual target paths.
- Code blocks must have language tags (e.g.
```bash,```markdown,```json).
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.

book AGENTS.md is an instructions file published in the GitHub repository aipmer/book (53 stars, last pushed 15d ago), licensed Apache-2.0. It adds 654 tokens to every session, about $0.0033 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.
