We've added a new harness!

Cursor Composer 2.5 is live in Conductor.

It's fast, precise, and cost-efficient. And when I say fast I mean _really_ fast. Excited to hear your thoughts!

Hey team, this looks great, but I think today's update may have broken an unrelated flow...

The "new workspace" flow now shows this popup instead of creating the full workspace first.

I usually browse the file tree and check a few docs before I start prompting. With this latest update, I can't really do that anymore, so I end up having to open an IDE and work from there first, which isn't ideal.

@charlieholtz a worthy addition - are you planning on providing full cursor lineup by chance so we could switch out models if someone didnt have another sub?

@betocmn You can press create without typing anything and you’ll get same behavior!

@charlieholtz I’m getting messages saying my conductor experience is suboptimal because I’m still on macOS 15. What conductor goodies do I get from upgrading macOS?

@charlieholtz Can't wait to try! 🪩

Bug report: the get key button is not working for me 😅

@charlieholtz This sounds promising for daily use

Faster results without the cost penalty is what we need

@charlieholtz How do you find it compares to GPT 5.5?

Any plans to build an intelligent router (like bitrouter) that can choose the model based on thinking and effort required, and can learn to route better with time and user feedback?

@charlieholtz half the wins in agent tooling lately are coming from the harness, not the model. nice to see this getting attention.
