How does this skill handle null checks?

It enforces explicit null checks (e.g., using value != null) instead of implicit truthiness to prevent common bugs associated with '0', empty strings, or booleans.

Can it help with ESLint errors?

Yes, it provides specific recommended rules and configurations for @typescript-eslint/strict-type-checked and other essential quality plugins to ensure code consistency.

Does it support React development?

Absolutely. It is automatically triggered by .tsx files and includes guidance on React-specific patterns like safe conditional rendering and prop typing.

What advanced TypeScript features are covered?

The skill covers discriminated unions, function overloads, constrained generics, and the mastery of utility types like Pick, Omit, and Record.

How do I trigger this skill in Claude Code?

The skill invokes automatically when you work with .ts, .tsx, .js, or .jsx files, or whenever Claude detects type errors, ESLint issues, or mentions of strict mode.
