Codex feels cleaner on a blank project than inside a messy legacy codebase

A Reddit user says they gave Codex an empty folder and used it to build a game from scratch with no bugs so far. They ask whether AI coding works better on greenfield projects than on existing codebases with many dev styles, where the model has to infer structure, conventions, and intent.
The post is a practical question about workflow rather than a product launch: it highlights a common claim that agentic coding tools are strongest when they control the whole codebase, and more brittle when they must fit into messy legacy systems.
