Best Claude coding prompts for beginners

The golden prompt pattern

Use: goal, context, constraints, what happened, and the exact output you want. The more specific your prompt, the less Claude has to guess.

Goal: Fix the Add button.
Context: Plain JS task app. Files: index.html and app.js.
What happened: Clicking Add does nothing. No console error.
Constraint: Make the smallest fix.
Output: Explain likely causes, then show only changed lines.

Prompts that teach while building

• “Ask me questions before coding.”
• “Explain every changed line.”
• “Give me a manual test checklist.”
• “Tell me what not to change.”
• “Show a simpler version first.”

Prompts to avoid

Avoid vague instructions like “make me an app.” They usually create too much code and too little learning. Ask for the smallest useful version instead.
