Be careful about what you hand off to Claude versus another agent. Claude is a vibe project monster, but it will fail at hard things, come up with fake solutions, and then lie to you about them. To the point that it'll add random sleeps and do pointless work to cover up the fact that it's reward hacking. It's also very messy.

For brownfield work, work on hard stuff or work in big complex codebases you'll save yourself a lot of pain if you use Codex instead of CC.

Claude is amazing at brownfield if you take the time to experiment with your approach.

Codex is stronger out of the box but properly customized Claude can't be matched at the moment

The issue with Claude are twofold:
1. Poor long context performance compared to GPT5.1, so Claude gets confused about things when it has to do exploration in the middle of a task.
2. Claude is very completion driven, and very opinionated, so if your codebase has its own opinions Claude will fight you, and if there are things that are hard to get right, rather than come back and ask for advice, Claude will try to stub/mock it ("let's try a simpler solution...") which would be fine, except that it'll report that it completed the task as written.

What have you done to make Claude stronger on brownfields work? This is very interesting to me.
