Run on entire project:

cd project-root && pyright

Configuration

Create pyrightconfig.json in project root for custom settings:

{
  "include": ["src"],
  "exclude": ["**/node_modules", "**/__pycache__"],
  "typeCheckingMode": "basic",
  "pythonVersion": "3.10"
}

Integration Pattern

When editing Python code:

1. Run pyright after significant changes
2. Address type errors before committing
3. Use diagnostics to improve code quality
