RT ，最近主力切换到 CodeX 之后发现 CodeX 会写无穷无尽的胶水代码、兜底代码和一些根本不存在的转换/try-catch 等等，哪怕在 prompt 里详细写清楚需要做的事情，或者用 Opus 4.7 写 plan 再执行也不会有很大改善。仿佛这种倾向刻进 CodeX 骨子里了。今天让它写一个简单的训练脚本，100 行的脚本里有一半是对一个命令行参数是否正确输入的判断，彻底晕了。 之前自己在网上找了一些方法写进 AGENTS.md 里，

## Coding Standard
1. Simplicity First.
2. Failfast instead of over-design, over-engineering, over-error-handling and over-fallbacks
   - Only make changes that are directly requested or clearly necessary. Keep solutions simple and focused.
   - A simple feature doesn't need extra configurability.
   - Don't add error handling, fallbacks, or validation for scenarios that can't happen. Trust internal code andframework guarantees. Only validate at system boundaries (user input, external APIs).Don't use feature flagsor backwards-compatibility shims when you can just change the code.
   - Don't create helpers, utilities, or abstractions for one-time operations.Don't design for hypotheticalfuture requirements. The right amount of complexity is the minimum needed for the current task-three similarlines of code is better than a premature abstraction
   - Avoid backwards-compatibility hacks like renaming unused _vars, re-exporting types, adding // removedcomments for removed code, etc. If you are certain that something is unused, you can delete it completely

And also the coding-rules and other guidelines/skills

也装了 andrej-kaparthy-guidelines, superpowers 之类的 skill ，实在是限制不了。大家有什么建议/经验吗，或者还是说回到 Claude 是更好的选择😭
