How do I inject a dependency to a file/directory without explicitly mentioning it in the README

[mfts]

I need python3 to run prepare-commit-msg (notably without a file extension) but it's a python file (see https://github.com/mfts/tea-demos/blob/feat/ai-commit-msg/ai-commit-msg/prepare-commit-msg.py).
This file gets placed in .git/hooks directory of my current directory and executes on git commit.

I don't want to change the user's behaviour of forcing the user to do something like

tea +python.org^3 +git-scm.org git commit

But I want python in the environment whenever git commit runs in that directory.

Something else I tried: changing the shebang in Line 1 on prepare-commit-msg to #!/usr/bin/env -S tea python3
unfortunately, that results in this error message

env: tea: No such file or directory

The shebang will work.

env: tea: No such file or directory

Means that tea is not in your PATH as far as git is concerned. How are you doing your commits?

If you are just doing git commit and tea --version works then it is weird that the environment your git calls its hooks from doesn’t use PATH
