This mini-application was written by one of my subscribers. His original intention was to have me optimize and review the prompt for a small application he's currently developing.

But to be honest, when I saw the beginning, I couldn't bear to read on. I apologize for any offense, but please forgive my blunt honesty.

Question:
I often have copy-paste needs:
Function 1: One-click summary
Meaning: Select a directory, read all file contents under that directory (including subdirectories), and output to content_Summary.md in the current program (supports custom character replacement).
Example: Current file directory structure:
"""
my_app/
    |—— src/
    |    |—— main/
    |    |    |—— java/

First point: For a brand new project, I personally believe that the first step should be to determine the application's scenario platform and which technology stack to use, rather than jumping straight into a detailed problem breakdown and piling up a bunch of feature points. The initial primary consideration should be which platform the application is suitable for, what need it aims to solve, and what final effect it should achieve.

This is like writing a structured essay for college entrance exams - there should always be a framework structure similar to introduction-body-conclusion.

Second point: The core requirement is "package code for AI to see, then be able to restore it," but the document is cluttered with numerous peripheral functions (template systems, complex configurations, rehearsal modes, etc.).

These things are needed, but there's absolutely no need to include them as initial project content. At least the main business logic should be running first, then iterate and refine these peripheral functions.

But now it's completely trying to grab everything at once - the AI might start implementing some specific peripheral task before the project framework is even set up, which could also lead to cascading errors.
