Claude prompt tips
Every AI tool responds differently to prompt structure. Here's what works best with Claude:
Use XML tags (<context>, <instructions>, <output>) — Claude is trained to follow them as structural markers.
Place the most important instructions near the end of long prompts — Claude has strong recency bias in long contexts.
Claude handles very long contexts well. Don't hesitate to include full documents.
Specify 'think step by step' for complex reasoning — Claude's extended thinking mode activates explicitly.

Claude prompt example: before and after
See how Prompt God transforms a vague Claude prompt into a structured, model-optimized instruction:
review my code
Act as a senior software engineer conducting a code review. Review the following code for: (1) bugs, (2) performance issues, (3) readability improvements, (4) security vulnerabilities. For each issue: state the line, the problem, and the fix. Constraints: TypeScript, React 18. Output: numbered list per category.
