Why This Claude Code Prompt for “Write a SQL Query” Works Better
When you type “Write a SQL query to get [specific data] from my database” 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.
