Why This Claude Code Prompt for “Refactor a React Component” Works Better

When you type “Refactor this React component to be more efficient and maintainable” into Claude Code, it lacks structure — Claude Code has to guess what format you want, how detailed to go, and what to prioritize. The optimized version removes that guesswork.

It starts with verification criteria (what 'done' looks like), describes the desired outcome rather than implementation steps, and scopes the task to specific files — matching Claude Code's agentic workflow.
