GitHub - Doriandarko/maestro: A framework for Claude Opus to intelligently orchestrate subagents.

初步使用了一下，可能是我使用不当，感觉并没有很厉害

1)克隆代码库

git clone GitHub - Doriandarko/maestro: A framework for Claude Opus to intelligently orchestrate subagents. 2)我用的是ollama

maestro-ollama.py

Folder Structure: Provide the folder structure as a valid JSON object, where each key represents a folder or file, and nested keys represent subfolders. Use null values for files. Ensure the JSON is properly formatted without any syntax errors. Please make sure all keys are enclosed in double quotes, and ensure objects are correctly encapsulated with braces, separating items with commas as necessary. Wrap the JSON object in  tags.\n\n3. Code Files: For each code file, include ONLY the file name, NEVER EVER USE THE FILE PATH OR ANY OTHER FORMATTING.
