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 | $0.00539 | $0.00539 |
| Opus 5.5 | $0.00216 | $0.00216 |
| Sonnet 5.5 | $0.00108 | $0.00108 |
| Haiku 4.5 | $0.00054 | $0.00054 |
Grade A, and why
ai-product-playbook 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 1mo 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 — 28 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository Guidelines
Project Structure & Module Organization
This repository publishes a VitePress online book. Numbered chapters live in model/, platform/, and applications/. Reusable, unnumbered assets live in toolkit/; concise supporting examples live in cases/. Do not create duplicate article bodies under book/ or elsewhere. scripts/generate-content-index.mjs scans those directories and generates the VitePress index plus the marked catalogue in README.md. Theme code is in .vitepress/theme/ and site configuration is in .vitepress/config.ts.
Build, Test, and Development Commands
npm run docs:dev— regenerate the content index and start local development.npm run check— run regression tests and verify committed content indexes without rewriting them.npm run docs:build— regenerate the index and build.vitepress/dist; run before every commit.npm run docs:preview— serve the existing production build locally.git diff --check— catch whitespace errors before committing.
Run npm run check and npm run docs:build before committing. Regression tests cover deployment filters and generated-index parity. Correct generated chapter count and a manual check of changed links remain part of the required validation baseline. If chapter titles or membership change, run npm run docs:prepare and commit both generated outputs.
Content, Style, and Naming
Keep filenames numbered and kebab-cased, for example platform/03-agent-reliability.md; the generator defines reading order from filenames. Preserve each article's first-level title, section marker, and 撰写日期 line. Write public-facing Chinese that is restrained, specific, and professional; remove internal credentials, private operational details, chat transcripts, and implementation details that do not change a reader's future decision. Edit navigation rules in scripts/generate-content-index.mjs, not generated files under .vitepress/generated/.
Commits, Pull Requests, and Deployment
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.
