project-os

project-os is a skill for Claude Code, Codex from Peiiii/skild. It costs 19 tokens per session (763 once invoked), scanned A, original, MIT.

A project-management system for coding agents that defines development rules, logs, commands, workflows, and release checks. It is designed to guide work from a request through implementation, testing, deployment, and review.

In plain words
What is it for?
Use it to set up project instructions, organize development commands and logs, run build and validation checks, perform smoke tests, and document release workflows.
Why use it?
It reduces inconsistent processes by giving the agent one set of rules and a traceable record of what happened. It must be initialized in a project before it takes effect.

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

project-os 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 6d 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

Project OS

用于在新项目中快速落地“开发规范 + 迭代日志 + 发布闭环”的通用体系(Project OS),面向未来演进为可自治、可编排、自动驱动研发流程的 AI 操作系统。

三段式定位

  1. 自治闭环
    覆盖需求—实现—验证—发布—线上冒烟—复盘的端到端闭环,系统自动推动流程完成并形成可追踪证据链。

  2. 自动化编排
    将研发流程拆解为可编排的步骤与指令(commands/skills/workflows),以最小人工干预串联执行、回滚与验收。

  3. 规则驱动执行
    所有行为由 Rulebook 统一约束与裁决,确保执行一致性、合规性与可审计性;如需例外必须显式声明并记录。

适用场景

  • 想把一套严格交付流程迁移到其他项目。
  • 需要在团队内统一验证/冒烟/发布规范。

启用方式(必须先初始化才生效)

本 Skill 安装后不会自动生效,首次使用时需要初始化;初始化完成后规则与流程才会被执行。

初始化流程(首次使用)

  1. 用户安装本 Skill 并开始与 agent 对话。
  2. agent 检测到目标项目尚未初始化(如缺少 AGENTS.md/commands/docs/logs)。
  3. agent 主动提示初始化必要性与影响,并请求确认。
  4. 用户确认后,agent 自动完成初始化并反馈结果。

初始化会做什么

  • 生成/更新 AGENTS.md(若已存在,则合并而非覆盖)
  • 生成/更新 commands/commands.md
  • 生成/更新 docs/logsdocs/workflows
  • 保证规则、指令索引、日志制度完整落地

手动初始化(仅作为兜底)

将本 Skill 的模板复制到目标项目根目录(若已有文件,需合并而非覆盖):

cp -R <skill>/assets/commands ./commands
cp -R <skill>/assets/docs ./docs
cp <skill>/assets/AGENTS.template.md ./AGENTS.md

关键约束

  • “完成所有/完成全部”默认执行完整上线闭环(migrations -> deploy -> 线上冒烟)。
  • 冒烟测试默认使用非仓库目录环境,禁止写入仓库子目录。
  • 每次开发阶段结束必须完成 build/lint/tsc + 冒烟(如适用)。

扩展与维护

  • 新增/修改指令:更新 commands/commands.md 并同步 AGENTS 索引。
  • 新增/修改规则:只在 AGENTS 的 Rulebook 维护。
  • 发布流程统一写入 docs/workflows/npm-release-process.md

模板索引

  • assets/AGENTS.template.md
  • assets/commands/commands.md
  • assets/docs/logs/TEMPLATE.md
  • assets/docs/logs/README.md
  • assets/docs/workflows/npm-release-process.md
Files

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

project-os is a skill published in the GitHub repository Peiiii/skild (113 stars, last pushed 6mo ago), licensed MIT. It adds 19 tokens to every session and 763 once invoked, about $0.0001 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.
