There is not a lot of explanation WHY is this better than doing the opposite: start coding and see how it goes and how this would apply to Codex models.

I do exactly the same, I even developed my own workflows wit Pi agent, which works really well. Here is the reason:

- Claude needs a lot more steering than other models, it's too eager to do stuff and does stupid things and write terrible code without feedback.

- Claude is very good at following the plan, you can even use a much cheaper model if you have a good plan. For example I list every single file which needs edits with a short explanation.

- At the end of the plan, I have a clear picture in my head how the feature will exactly look like and I can be pretty sure the end result will be good enough (given that the model is good at following the plan).

A lot of things don't need planning at all. Simple fixes, refactoring, simple scripts, packaging, etc. Just keep it simple.
