Conduct requirement analysis and key point breakdown based on the user's requirements
Based on the requirement breakdown from the first step, guide the user to answer and confirm unclear content; for scenarios with multiple solutions, provide suggestions and ask the user for confirmation.
Send the revised requirement key points to the user for confirmation.
Write the requirements analysis document with reference to the requirement-ex.md file under the example folder, and place the requirements analysis document in the output/doc folder under the root directory of the current working directory. The file name is requirements-analysis.md, where output is the root directory for this output.
