senmu-buildos: Instructions file for Codex

AGENTS.md

senmu-buildos AGENTS.md is an instructions file for Codex, OpenCode from SenMuShare/senmu-buildos. It costs 317 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for SenMuShare's BuildOS project, an engineering governance and coaching system for coding agents. They define which project copy is authoritative and which files may be edited.

In plain words
What is it for?
Use them before editing, testing, updating skills, recording governance work, regenerating the public projection, or preparing a release.
Why use it?
They prevent changes from being made in a generated public copy or being published without the required checks and permission.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Codex.

This is SenMuShare/senmu-buildos's own configuration. It tells Codex and OpenCode how to work on senmu-buildos itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything senmu-buildos configures →

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.

Security

Grade A, and why

senmu-buildos 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 yesterday.

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

Senmu BuildOS 仓库身份与编辑边界

在修改前先判定当前根的身份:

  • 存在 .senmu-buildos/config.json:这是内部权威库,Bug 修复、Skill 更新、测试和治理记录在此完成。
  • 存在 .senmu-public-projection.json:这是可重建的公开投影,只允许检查和发布复核,禁止直接修改。将问题返回内部 owner 修复后重新生成投影。
  • 两个标记都不存在:不要猜测当前副本是 owner;先查找工作区地图或请求用户指明权威根。

本机 Codex 刷新只消费内部库的已验证 commit。公开投影生成不等于发布;GitHub push、Tag 和 Release 需要用户单独的明确发布授权。

内部库的具体命令和门禁见 governance/PUBLICATION.md。普通源码任务按目标 Skill/reference owner 直接执行;只有治理或发布决策才加载相应专业 Skill。

修改 Skill 时核对其引用和消费者;包检查为 python3 scripts/validate_package.py,Python 回归为 python3 -m unittest discover -s tests -p 'test_*.py',Hook 回归为 node --test tests/hooks/*.test.js。按影响选取检查,安装刷新前完成配置声明的全部门禁。规则行为和性能结论须与结构检查分开报告。

Changes

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.
