## Git Commit Guidelines

- **Do NOT amend, squash, or rebase commits that have already been pushed to the PR branch after the PR is opened** - Reviewers need to follow the commit history, as well as see what changed since their last review

## Development Commands

.vscode/tasks.json contains useful commands used for development.

## Python Syntax Notes

- Python 3.14 explicitly allows `except TypeA, TypeB:` without parentheses.

## Testing

When writing or modifying tests, ensure all test function parameters have type annotations.
Prefer concrete types (for example, `HomeAssistant`, `MockConfigEntry`, etc.) over `Any`.

## Good practices

Integrations with Platinum or Gold level in the Integration Quality Scale reflect a high standard of code quality and maintainability. When looking for examples of something, these are good places to start. The level is indicated in the manifest.json of the integration.
