# the plugin never depends on a globally-installed console script.
#
# A pip-installed entry point is not dependable here: under pyenv the shim resolves against
# whichever Python version the current directory selects, so a repo with a .python-version
# pinning a different version fails with "pyenv: mem0-agent: command not found".
#
# The package has no third-party dependencies, so any CPython >= 3.10 can run it straight
# from source.
