I have some algorithms I absolutely must know. So I’m hand coding them and asking the agent to critique me.

I do a very similar thing in writing - I need feedback, don’t rewrite this!

In both cases I need the struggle of editing / failing to arrive at a deeper understanding.

The future dev will need to know when to hand code vs when to not waste your time. And the advantage will still go to the person willing to experience struggle to understand what they need to.
