How does this skill help other Claude skills?

It provides a shared convention and authoritative location so multiple skills can install and access their Python dependencies in a predictable and conflict-free way.

Does it handle pip package installation?

Yes, it includes built-in workflows for installing one or more packages into a specific venv and verifying the installation.

Where does this skill store Python virtual environments?

All environments are stored in a standardized, centralized hidden directory located at ~/.venvs/ /.

Can I list or remove environments with this skill?

Yes, the skill provides commands to list all existing venvs and includes a safe removal workflow that requires user confirmation before deletion.

Why is running commands via the venv path preferred over activation?

Running commands directly via ~/.venvs/ /bin/ is more robust for automation as it avoids shell state issues associated with 'source activate' and 'deactivate'.
