Claude Code - strengths & limits

  • Strong at explaining and refactoring unfamiliar code

Watch out for

  • Requires a paid Claude plan or API credits to use
  • Agentic edits still need review before you trust them
  • Token usage on large repositories can add up quickly

Which should you choose?

If your priority is terminal workflows, git-centric editing, refactoring, scripted changes, Aider is the stronger pick.
