• Run targeted tests, and lint continuously during development
• Prioritize understanding existing patterns before implementing
• Don't commit changes, leave it for the user to review and make commits

Linting and Formatting

• Lint: yarn lint-eslint-pure
  • Run ESLint on the codebase
• Format: yarn prettier
  • Format code using Prettier
• Type Check: yarn type-check-pure
  • Run TypeScript type checking
