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 | $0.00540 | $0.00540 |
| Opus 5 | $0.00270 | $0.00270 |
| Sonnet 5 | $0.00108 | $0.00108 |
| Haiku 4.5 | $0.00054 | $0.00054 |
Grade A, and why
open-browser-use 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 3d 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.
This is a copy
89% identical to open-codex-computer-use AGENTS.md — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
open-browser-use
这个仓库是一个面向 Agent 协作开发的基础模板。
AGENTS.md 故意保持简短，只负责做导航，不负责塞满所有规则。仓库内的 docs/ 才是本地知识的正式来源。
如果一次代码或流程变更会让某份文档过期，就在同一轮任务里顺手把它改掉。
每轮开始先读
docs/REPO_COLLAB_GUIDE.md：仓库级协作、提交、文档同步与测试约定。docs/ARCHITECTURE.md：仓库整体结构和预期边界。docs/design-docs/core-beliefs.md：Agent-first 的工作原则和这个模板的设计出发点。
代码改完前要读
docs/HISTORY_GUIDE.md：什么时候记 history、怎么命名、怎么脱敏。docs/QUALITY_SCORE.md：当前质量分层和主要短板。
按任务需要选读
docs/PLANS_GUIDE.md：什么时候要写 execution plan，怎么维护。docs/PRODUCT_SENSE.md：产品价值、取舍方式和优先级判断。docs/RELIABILITY.md：运行稳定性、观测性和上线前的基本要求。docs/SECURITY.md：认证、数据处理、外部集成等安全默认约束。docs/SUPPLY_CHAIN_SECURITY.md：依赖、SBOM、制品 provenance 和仓库级供应链安全默认做法。docs/CICD.md：仓库的 CI/CD 骨架以及后续如何接入真实项目。docs/FRONTEND.md：如果仓库包含前端界面，这里记录对应规范。CONTRIBUTING.md：提 PR 前后的默认检查项和协作要求。docs/releases/README.md：如何维护面向用户的发布记录。docs/references/README.md：沉淀到仓库里的外部参考资料。
工作规则
- 优先选择小而清晰、对仓库和 Agent 都友好的抽象。
- prompt、规则、架构约束尽量都版本化落在仓库里。
- 复杂任务不要只靠聊天上下文，应该落 execution plan。
- 完成的代码变更要记到
docs/histories/。
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.

open-browser-use AGENTS.md is an instructions file published in the GitHub repository iFurySt/open-browser-use (257 stars, last pushed 1mo ago), licensed MIT. It adds 540 tokens to every session, about $0.0027 per session on Opus 5. A static security scan graded it A with 0 findings. It is 89% identical to open-codex-computer-use AGENTS.md, differing in 6 lines, and is treated as a copy.
