What is the 'No Backwards Compatibility' principle?

It encourages developers to delete unused code and update interfaces directly during development rather than maintaining legacy shims, which significantly reduces long-term technical debt.

Does this skill support Node.js?

Yes, it is designed for modern environments, specifically supporting Node 22+ and Bun for ESM-native projects by default.

How does this skill handle project validation?

It utilizes Zod for runtime validation at project boundaries (APIs, Database, Config), ensuring that your strictly typed TypeScript code remains safe even when dealing with external data.

Why does the skill recommend LiteLLM?

LiteLLM provides a unified interface for over 100 LLM providers, allowing you to switch models or providers via configuration without changing your core application code.
