TLDR

Small Python CSV explorer that previews rows and column statistics; the README is sparse and most details have to be read from the source under src/.

README does not document CLI flags or what the tool prints; you have to read src/main.py to find out.

In plain English

csvlens-pro is a small Python project for looking at CSV files. The README describes it in one line as a CSV explorer and lightweight visualizer, and lists one feature: previewing CSV rows and column statistics. There is no further detail about what those statistics include, what the interface looks like, or how visualization is presented. To install it, you clone the repository and run pip install -r requirements.txt to pull in its Python dependencies. To start the tool, you run python src/main.py from the project directory. The README does not say what happens when you run that command, whether it opens a terminal interface or a graphical window, or how you point it at a specific CSV file. There is a test suite that can be run with python -m unittest discover, which is the standard way to find and execute Python unit tests in a project. The README does not describe what is covered by the tests. The last section of the README is a set of generic git commands for initializing a repository and pushing it to GitHub, with a placeholder for a username. These look like template instructions left in by whoever scaffolded the project rather than guidance specific to using csvlens-pro itself. Overall the README is very sparse. It tells you the project exists, that it reads CSV files, that it has some kind of preview and column statistics, and how to install and run it. It does not document command-line options, file format expectations, supported data types, output format, screenshots, or limitations. Anyone wanting to know what the tool actually does in practice would need to read the source under src/ to find out.

Copy-paste prompts

Prompt 1
Clone csvlens-pro, install requirements, run python src/main.py, and tell me what interface it actually shows
Prompt 2
Trace through src/main.py in csvlens-pro and document the real command-line arguments it accepts
Prompt 3
Add a --file flag to csvlens-pro so I can point it at a specific CSV instead of guessing
Prompt 4
Run python -m unittest discover on csvlens-pro and explain which behaviors are covered by the tests
Prompt 5
Extend csvlens-pro to print min, max, and mean per numeric column in addition to its current preview
