Ever since OpenAI launched the GPT-5.4-mini version, I think this repository is worth checking out, especially for those using Codex to write code～ This repository organizes over 130 Codex subagents. They’re categorized into 10 directions: Development, Language, Infra, Security, Data, AI Products, Research, Orchestration—pretty much everything is covered. You can use the reviewer specifically for code reviews, use the docs researcher to look up documentation, use the debugger to troubleshoot issues, and run frontend, backend, and infra separately. When using Codex CLI, you can leave the decision-making to GPT-5.4 and assign super simple tasks to these subagents. PS: Don’t configure everything—just let your AI pick a few that you use frequently. Installing too many won’t be very helpful. As usual, the repository link is in the comments
