Limit Optional Properties

What it does

This skill allows you to limit the properties that can be optional in TypeScript interfaces or types. It enforces stricter type safety by preventing unintended omission of required fields, leading to more robust and predictable code. The skill helps ensure all expected properties are present when creating objects conforming to these types.

When to use it

• When building complex data structures where missing properties could lead to runtime errors.
• To enforce consistency across a codebase by preventing developers from accidentally omitting required fields.
• During refactoring of existing TypeScript codebases to improve type safety and reduce potential bugs.
• In projects with strict coding standards that require explicit declaration of all properties.

Key capabilities

• Enforces optional property restrictions in TypeScript interfaces/types.
• Provides a mechanism for defining required properties within optional structures.
• Improves code maintainability by reducing ambiguity around optional fields.

Example prompts

• "Apply the limit-optional-properties skill to this interface: interface User { name?: string; age?: number; }"
• “Can you ensure that all properties in this type are explicitly defined and not implicitly optional?”
• "Refactor this TypeScript code to prevent any optional properties from being omitted."

Tips & gotchas

This skill requires a working TypeScript environment. It's most effective when applied during the design or refactoring phase of a project, rather than as a retroactive fix for existing code with inconsistent property definitions.
