Typescript Satisfies Operator

What it does

This skill allows an AI agent to verify if a given type satisfies a specific TypeScript operator. It can be used to check if a type is compatible with a conditional type, mapped types, or other advanced TypeScript features. This ensures type safety and helps prevent runtime errors by validating the structure of data at compile time.

When to use it

• Type Validation: Confirm that a custom type correctly satisfies a complex conditional type definition in your code.
• Refactoring: Verify that changes made during refactoring don't break existing type constraints.
• Library Development: Ensure user-provided types are compatible with the API of a TypeScript library you’re building.
• Code Generation: Validate generated TypeScript code to ensure it adheres to specific type requirements.

Key capabilities

• Type satisfaction checking for TypeScript operators.
• Verification of custom types against complex conditional and mapped types.
• Compile-time type safety validation.

Example prompts

• "Does string[] satisfy the operator Array<T>?"
• "Verify that { name: string } satisfies Partial<{ id: number, age: number }>."
• "Check if Record<string, number> satisfies {[key: string]: number}."

Tips & gotchas

• Requires a working TypeScript environment. The agent will need access to the TypeScript compiler for type checking.
• Complex types and operators can be difficult to express in natural language; be as precise as possible with your prompt.
