What problem does it solve?

This Skill helps you reduce maintenance pain in TypeScript codebases by preventing type leaks, runtime mismatches, and boundary errors that spread through the call graph.

Core Features & Use Cases

It provides pragmatic guidance for designing type-driven architectures with strong module boundaries, safe handling of external data using unknown-and-narrowing, and maintainable error handling with typed errors and causes. It also recommends modern async patterns, dependency direction and side-effect placement to keep core logic framework-free, and ecosystem defaults (validation, ORMs, testing, HTTP) that fit typical Node/React/Next.js projects. It is especially useful when refactoring legacy code, scaling a monorepo, or standardizing conventions across a team.

Quick Start

Ask the AI to review your TypeScript project structure and propose concrete changes to strengthen type boundaries and improve async, error-handling, and module separation.
