  4. write unit tests for the calculator functions — write tests

  • Break complex tasks into numbered steps
  • Press ? for keyboard shortcuts, Tab for command completion, ↑ for history
  • Type / to see all commands and skills
  • Claude reads your files automatically — no need to manually add context
