创建或更新 Codex meta-scheduler watcher automation。用于为一个项目、milestone、parent issue、issue set、pull request、PR set、release、repo carrier 或手工目标维护 coordination unit graph、scheduler pool、candidate graph/pool、shared lane lock table、scheduler waiting queue 和调度线程生命周期；在安全并行时创建多个 scheduler thread，并在 shared lane 争用时执行 lane grant / wait / release / recovery。默认中文说明和回报，可适配用户语言；协议字段、状态枚举、工具名和结构化模板字段保持机器可读。
Codex 线程编排的 scheduler 与 worker 协作协议。用于 Codex 作为 scheduler 拆分全局目标、创建或恢复 worker、管理 branch/worktree、发送跨线程指令、运行 gate、完成 closeout；也用于 Codex 作为 worker 确认分配现场、创建并自检 scoped goal、只执行指定 scope、回报 scheduler-readable 关键节点，并等待 scheduler-owned gate。默认使用中文说明和回报，可根据用户语言适配；协议字段、状态枚举、工具名和结构化模板字段保持机器可读。
起草、优化或设置符合 OpenAI《Follow a goal》指南的 Codex goal。起草前先根据最新用户请求确定输出语言。为用户起草可复制的单行 /goal 命令；用户明确要求时，通过 goal 工具/API 创建自包含的 active goal objective。用户使用中文、混合语言或语言不明确时，输出中文。保留命令、路径、代码标识符、URL、issue ID、精确引用，以及 /goal、API、objective、copyable_goal_command、active_goal_api 等标识原文。

| description | Identify the minimal set of tests to run after code changes using CodeGraph. |
Use this skill after code has been modified to determine which tests should be run to validate the change. It helps avoid running the entire test suite unnecessarily.
Goal: Recommend a focused set of tests that exercises the affected areas and an extended set for regression.
Auxiliary files:
scripts/codegraph-affected.sh as the CLI fallback wrapper when MCP test discovery is unavailable or codegraph affected is preferred.reference/test-selection-rules.md to classify minimal, caller and regression tests.Shared tool policy:
../../reference/codegraph-tool-policy.md for common CodeGraph tool selection, fallback and unavailable handling.Task-specific tools:
codegraph_impact through MCP or scripts/codegraph-affected.sh for CLI fallback. CodeGraph does not yet expose a dedicated test-finding MCP tool.Workflow:
git diff --name-only HEAD or the list provided by the user.reference/test-selection-rules.md.codegraph_status to ensure the index is current.scripts/codegraph-affected.sh with the changed files, or pipe file names into it. It calls codegraph affected --stdin --json and returns structured output.codegraph_impact and collect all test files (often under __tests__, tests/ or similar) in the impact radius.Rules:
reference/test-selection-rules.md.
