Example of using Ollama in Open WebUI locally to make a decision record for implementing domain events in C#.
This is what I'm talking about. Run those local LLMs and use the tools you have at hand. Don't trust output without reviewing first!.

- BE EXPLICIT - specify headings in a particular order, specify the format you need.
- Walk it through your decision - use a model that has summarize capabilities for better success, talk through your decision and let it organize into the desired format
