Python Type Hints Converter

The python-type-hints-converter skill automatically adds type annotations to Python code, enhancing readability and enabling static analysis tools to catch errors before runtime. It transforms untyped scripts into robust, maintainable modules that align with modern Python best practices.

When to use it

• Refactoring legacy Python codebases lacking type definitions to improve long-term maintainability.
• Preparing code for deployment in environments requiring strict type checking or IDE support.
• Generating documentation-ready code where explicit types clarify function inputs and outputs.
• Integrating with linters like mypy or formatters that rely on accurate type information.

Key capabilities

• Detects untyped functions, classes, and variables within Python source files.
• Infers appropriate type hints based on usage patterns and standard library conventions.
• Outputs fully annotated code ready for integration into existing projects.

Example prompts

• "Convert this untyped Python function to include proper type hints."
• "Add type annotations to all methods in this class definition."
• "Generate a version of this script with full type checking support using modern Python syntax."

Tips & gotchas

Ensure your Python environment supports the target version’s typing features (e.g., typing module for older versions). The tool may infer less precise types if the code logic is ambiguous or overly dynamic.
