strict-typescript-mode

What problem does it solve?

This skill enforces TypeScript best practices to improve safety, readability, and maintainability by preventing implicit any usage and requiring explicit types.

Core Features & Use Cases

• Enforces explicit return types and public API types to prevent accidental type leakage.
• Forbids usage of any in new code unless there is a documented justification, with type guards and runtime checks where appropriate.
• Encourages the use of generic constraints and TypeScript utility types to create safer abstractions.
• Use Case: When converting a JavaScript project to TypeScript or implementing new features, this skill guides developers to write type-safe, robust code.

Quick Start

• Update tsconfig.json to enable strict mode and helpful flags (e.g., "strict": true, "noImplicitAny": true, "strictNullChecks": true).
• Add lint rules to enforce explicit types on exports and disallow bare any usages.
• Run the TypeScript compiler and linting tools (tsc, eslint) to validate code changes.
