The biggest tip I can give you is to stay in the framework you are most convenient in, and have the most experience. Start building stuff the way you would by yourself, but then start delegating the repetitive tasks to an agent. My best recommendations would be using Cursor in Agent mode, and switching to VScode in Agent mode when your credits with Cursor run out. The reason why I like Cursor more is because of the Checkpoints. And VScode Copilot Agent checkpoints suck; but you can still use git to create your own checkpoints (git add / git stash, etc).

I don't even use completions, really just agent mode. I do planning, wireframing, creating specs all with agents. Even small MVPs created in 5 minutes, deployed in 10, during a meeting to just brainstorm. As for the models. Go with Claude 3.5 or 4.0, GPT5. Use sequentialthinking and Taskmaster MCP. I could write a book about it... but the best way to go about it is to dive into, get frustrated, push through and then learn it the hard way. I started delegating a lot of my programming work the day ChatGPT came out; just copy and pasting, and since that day, my reliance on AI has just been increasing, and I have been getting better at it (and now I am at this stage.. with 2 PMS).
