Y Combinator Startup Podcast · Boris Cherny: Building Claude Code · 28 Jul 2026 podcast

Let's talk a bit about the new release.

You actually deleted over 80% of the system prompt from Cloud Code.

Tell us more about that.

I think the thing that's really fascinating in this era of building, basically you have built the best harness in the world for

for Claude and that's Claude code.

From what I'm hearing, for every model release, you basically delete all of the code base, delete all of the prompt and start from scratch every time.

That in the old world would have been not something startup would have done for the product.

It's like press delete every six months for everything.

Do you think this way of building a agentic product and harness and basically doing ablations every time there's a new model release, should everyone in this room that's building AI products basically do that?

Be comfortable and brave to press delete?

Let's talk a bit about how then you build this new prompt when there's a new model release, like for everyone in the room, everyone will want to try Opus 5 and they're gonna press delete on their system prompt.

How do they go about rebuilding the system prompt?

How do you set up your environment?

If you're building in this world right now, what then becomes stable?

Are evals something that you keep from the previous models and keep using them in each new model release?

So that's sort of the tip for everyone.

So code and system prompt, if you want to build at the bleeding edge and have the most capability for models, you've got to delete those.

But evals are constant and keep appending to them, basically.

I think one term I heard you describe how to build the best agentic products on top of a plot is this concept of an unhobbling plot.

And tell us more about what that means.
