TypeScript/JavaScript Rules

These rules come from app/rules/typescript/ in ai-toolkit. They cover the project's standards for coding style, frameworks, patterns, security, and testing in TypeScript/JavaScript. Apply them when writing or reviewing TypeScript/JavaScript code.

TypeScript Coding Style

Strict Mode

• Always use strict: true in tsconfig.json.
• Never use any -- use unknown + type guards instead.
• Prefer interface over type for object shapes (extendable).
• Use as const for literal types and readonly tuples.
