Claude Code vs Codex TUI

Have to say I like a lot more this default style from Codex TUI to present the proposed changes. It is brief, it has the right keywords highlighted, it shows me the approaches considered so far, and it shows with bullet points the proposed architecture.

Three proposed approaches for a software architecture, with bulleted details on extensions and changes to system components highlighted. — Example of Codex TUI using GPT 5.6-sol on high

Compare with Claude Code style. I know it is not the same task but this wall of text. This is Claude Code with "simple technical English" instruction added in user injected Claude(dot)md

Still makes me re-read twice some parts:

Technical write-up detailing code changes for throttling requests and test environment caveats in a Ruby on Rails project. — Example of Claude Code TUI on Opus 5 xhigh

I like the idea of Claude that goes beyond what I have asked and tells me about a possible bug and investigation to be done as followup. But I wish it would have made that text a bit more structured by default.
