mikecreighton/ai-brainstorm ? reverse-engineered prompt

Build me a command line app that helps brainstorm ideas for a problem statement using an LLM.

I want to type in a problem, a few constraints, and what counts as a good idea, then have the tool generate lots of candidate ideas, score them, and keep improving the most promising ones over several rounds. It should organize the ideas in a tree so I can see how each idea evolved, and it should use a search style approach to balance trying new directions with refining the best ones.

Please make it work with common AI providers like OpenAI, OpenRouter, and Groq, and let me swap models easily. Save each run to a file as it goes, show the best ideas at the end, and let me continue from a previous run if I want to keep exploring. If you need to check current API docs or model names, look them up online.
