essentials: Command for Claude Code

Add helpful Python dependencies to the current uv project.

Parameters

• package_dir: The directory path where the Python package's pyproject.toml file is located

Behavior

1. If package_dir is not provided, check for a pyproject.toml file in the current directory. If no pyproject.toml is found, ask the user: "What is the package directory location?"

2. Navigate to the package directory (use current directory if pyproject.toml exists there, otherwise use the provided or asked-for directory)

3. Add regular dependencies:

   • python-dotenv - For loading environment variables from .env files
   • python-decouple - For managing settings and configuration

4. Add development dependencies:

   • black - Code formatter
   • pre-commit - Git hooks framework
   • pylint - Linter for Python code
   • perflint - Performance linter
   • ruff - Fast Python linter and formatter
   • bandit - Security linter for Python
   • pytest - Testing framework
   • detect-secrets - Tool to detect secrets in code

Commands

Run these commands in the package directory (where pyproject.toml exists):

uv add python-dotenv python-decouple

uv add --group dev black pre-commit pylint perflint ruff bandit pytest detect-secrets

Example Usage

With parameter:

• package_dir: tools/python/my_package
• This will navigate to tools/python/my_package/ and run the uv add commands there

Without parameter:

• Check current directory for pyproject.toml
• If found, use current directory
• If not found, prompt user for package directory location
• Then proceed with adding dependencies

Notes

• The package directory must contain a pyproject.toml file
• The directory location can be absolute or relative to the workspace root
• The dev dependencies will be added to the [dependency-groups] dev section in pyproject.toml
• Regular dependencies will be added to the [project] dependencies section
