What it does

This skill enables AI agents to analyze TypeScript codebases and generate precise, type-safe interfaces. It assists developers in maintaining strict typing standards across complex applications.

When to use it

• Defining new interfaces or types for existing data structures.
• Refactoring legacy JavaScript code into fully typed TypeScript modules.
• Validating that function arguments and return values match expected schemas.
• Generating type definitions for third-party libraries with missing documentation.

Key capabilities

• Analyzes existing TypeScript files to infer correct type signatures.
• Generates .d.ts declaration files for untyped assets.
• Identifies potential type mismatches in function calls.
• Supports both strict and relaxed typing configurations.

Example prompts

• "Create a TypeScript interface for a user profile containing name, email, and age fields."
• "Refactor this JavaScript function to use strict TypeScript types with proper error handling."
• "Generate a type guard function to check if an object is a valid Product instance."

Tips & gotchas

Ensure your AI agent has access to the relevant codebase or schema documentation before requesting complex type definitions. For large projects, break requests into smaller modules to improve accuracy and reduce token usage.
