Type Value Space

What it does

The type-value-space skill allows AI agents to reason about the relationship between TypeScript types and their corresponding values. It can infer value ranges based on type definitions, identify potential runtime errors related to type mismatches, and generate code snippets that demonstrate type safety. This capability helps ensure more robust and predictable behavior in TypeScript applications.

When to use it

• Debugging Type Errors: When encountering cryptic TypeScript error messages, this skill can help clarify the underlying issue by explaining the expected value range for a given type.
• Code Generation & Refactoring: Generate code that adheres strictly to defined types and avoids common pitfalls related to incorrect value assignments.
• Understanding Complex Types: Simplify comprehension of intricate union or intersection types by outlining their possible values.
• Type Safety Validation: Verify if a given value conforms to a specific TypeScript type, proactively preventing runtime errors.

Key capabilities

• Value range inference from TypeScript types
• Identification of potential type mismatch errors
• Code snippet generation demonstrating type safety
• Explanation of complex TypeScript type constructs

Example prompts

• "What values are possible for string | number?"
• "Is the value 'hello' compatible with the type number?"
• "Generate a function that accepts an array of strings and ensures type safety."

Tips & gotchas

• The skill’s accuracy depends on the clarity and completeness of the TypeScript type definitions provided. Ambiguous or overly complex types may yield less precise results.
