Use when starting Codex work that needs an explicit Direct vs subagent choice: code edits, debugging, reviews, repo exploration, multi-file changes, ambiguous scope, high-risk judgment, or requests mentioning agents, subagents, delegation, parallel work, model choice, cost, token use, or over-delegation.
Use when 处理任何需要交付结论或产出物的非琐碎任务(调研、分析、排查问题、写方案、写文档、编码),尤其当任务带时间压力("快点、直接给答案")、信息来源可能互相矛盾、被要求汇报数字或事实、或产出要给他人做决策依据时。也用于用户想把这套工作方式移植到其他模型(取 portable 文件)。
