Python Types Contracts

What it does

This skill enables AI agents to understand and enforce type contracts within Python code. It allows developers to specify expected types for function arguments and return values, improving code reliability and catching errors early. The skill facilitates static analysis and helps ensure that functions behave as intended by verifying data types at runtime.

When to use it

• Refactoring legacy Python code: Enforce type safety in older projects lacking explicit type annotations.
• Developing new APIs: Define clear contracts for function inputs and outputs, improving API usability and maintainability.
• Improving code reliability: Catch type-related errors during development rather than at runtime.
• Collaborative coding environments: Ensure consistency and prevent misunderstandings among developers working on the same codebase.

Key capabilities

• Type contract enforcement for Python functions.
• Static analysis of code to identify potential type errors.
• Runtime verification of function argument and return types.

Example prompts

• "Add a type contract to this Python function: def calculate_average(numbers): ..."
• "Verify the type contracts for all functions in this file."
• "Generate type annotations for this Python code snippet."

Tips & gotchas

This skill requires a basic understanding of Python and its type hinting system. Ensure your environment has the necessary dependencies installed before attempting to use it, as it may require specific packages or libraries.
