Token cost

What it costs to keep this loaded

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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00540 $0.00540
Opus 5.5 $0.00216 $0.00216
Sonnet 5.5 $0.00108 $0.00108

Measured 2mo ago against content hash a6ff96a0d597, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

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 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.

Origin

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.
