+# Python Package Management with uv
+
+Use uv exclusively for Python package management in this project.
+
+## Package Management Commands
+
+- All Python dependencies **must be installed, synchronized, and locked** using uv
+- Never use pip, pip-tools, poetry, or conda directly for dependency management
+
+Use these commands:
+
+- Install dependencies: `uv add <package>`
+- Remove dependencies: `uv remove <package>`
+- Sync dependencies: `uv sync`
+
+## Running Python Code
+
+- Run a Python script with `uv run <script-name>.py`
+- Run Python tools like Pytest with `uv run pytest` or `uv run ruff`
+- Launch a Python repl with `uv run python`
+
+## Managing Scripts with PEP 723 Inline Metadata
+
+- Run a Python script with inline metadata (dependencies defined at the top of the file) with: `uv run script.py`
+- You can add or remove dependencies manually from the `dependencies =` section at the top of the script, or
+- Or using uv CLI:
+    - `uv add package-name --script script.py`
+    - `uv remove package-name --script script.py`
+
+
+
+# References
+- https://pydevtools.com/handbook/how-to/how-to-configure-claude-code-to-use-uv/
