So far the follow-up questions have all been really good design/engineering questions that I appreciate.
I saw a Youtube video that showed Sonnet-4.5 is much better than GPT-5 at making plans in Cursor and tried it out. I 100% agree! Sonnet plans tend to include what files to touch and details about the implementation. grok-code-fast-1 could nail the implementation on my last one
I’m already using it in another repo. without workspace.
I loved the PLAN mode too. Previously I had to tell the AI to just plan and not to implement anything. But sometimes, when I was revising the plan, it started to implement some changes and I had to revert. Now, using the PLAN mode, I have a piece of mind that it won’t happen. Also it seems that in the PLAN mode, it really try to understand the codebase thoroughly so I have an easier time writing my planning prompt. Good job Cursor Team!
Make a plan, clarify specifics, ask to be explicit, build.
Realize build is missing something, return to plan, adjust, build.
This is a nice approach because you can keep the agent consistently corralled to the plan, also if you ask the smarter planning agent to include better snippets that you want the implementation agent to use so they’re not just making it up as they go.
