Professional Pentesters spend 20% of their time hacking and 80% of their time fixing their tools. The ability to write a quick wrapper script to parse grep output and feed it into another tool is what separates the Pros from the Novices.
Example: Subdomain Parser
You run 5 different subdomain finder tools. They all output different formats.
Write a Python script to ingest CSV, JSON, and Text formats, deduplicate the list, and check which ones are alive.
This is your "Recon Framework".
1. Typer & Click
Use libraries like Typer to build beautiful Command Line Interfaces (CLI).
Don't just parse `sys.argv`.
Make your tools user friendly so your team can use them too.
2. Distribution
Package your tool with `PyInstaller`.
Turn your Python script into a standalone `.exe` or Binary.
Now you can run it on a client's machine without installing Python environments.
