name: ts description: TypeScript conventions and type-safe patterns.

Conventions

• Types: strict: true, type guards over assertions
• Null Safety: Optional chaining (?.), nullish coalescing (??)
• Style: interface for objects, type for unions, import type for types
• Tools: oxlint for linting, Vitest for testing

Testing

Copydescribe("feature", () => {
  it("behavior description", () => {
    // AAA pattern, expect API
  });
});
