SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Installing Python packages with a global `pip install` breaks project isolation and conflicts with existing tooling like uv, Poetry, or Conda. This Skill ensures every package installation respects the dependency manager already established in the project. ## Core Features & Use Cases - Dependency Manager Detection: Scans the workspace for signal files (`uv.lock`, `pyproject.toml`, `Pipfile`, `environment.yml`, `requirements.txt`) in priority order to identify the correct tool. - Tool-Specific Install Commands: Maps each detected manager to its proper install and setup commands, such as `uv add`, `poetry add`, or `pipenv install`. - Safe Default Workflow: Falls back to an isolated `.venv` with explicit `.venv/bin/pip` paths and `requirements.txt` freezing when no manager is found. - Use Case: When asked to add `requests` to a project containing a `uv.lock` file, the Skill runs `uv add requests` instead of a global `pip install`, keeping the lockfile consistent. ## Quick Start Add the pandas package to this Python project using the dependency manager it already uses.

FAQPage Schema

How do I install Python packages without using global pip?▼

Detect the project's dependency manager first, then use its install command such as `uv add`, `poetry add`, or `pipenv install`. If no manager exists, create a `.venv` and install with the explicit path `.venv/bin/pip install <package>`.

How do I know which Python dependency manager a project uses?▼

Check for signal files in priority order: `uv.lock` or `[tool.uv]` indicates uv, `[tool.poetry]` in pyproject.toml indicates Poetry, `Pipfile` indicates Pipenv, `environment.yml` indicates Conda, and `requirements.txt` alone indicates venv plus pip.

What is the difference between uv, Poetry, and Pipenv for installing packages?▼

uv uses `uv add` and `uv sync`, Poetry uses `poetry add` and `poetry install`, and Pipenv uses `pipenv install`. Each maintains its own lockfile, so you must use the manager the project already adopted rather than mixing tools.

Can I use pip install in a project that already uses Poetry or uv?▼

No. Overriding an existing dependency manager with pip bypasses its lockfile and corrupts the environment state. Always use the detected manager's own add command to keep dependencies consistent.

What should I do when a Python project has no dependency manager configured?▼

Default to venv plus pip: create the environment with `python3 -m venv .venv`, install packages via `.venv/bin/pip install`, and preserve state by running `.venv/bin/pip freeze > requirements.txt`.
