Improving Prompts

Overview

Apply current documented Anthropic best practices to existing prompts. Do not invent "improvements" — use the actual guidance.

When to Use

• Optimizing CLAUDE.md or AGENTS.md files
• Improving custom command prompts
• Refining skill instructions
• Migrating prompts to current Claude models (4.x)

When NOT to Use

• Writing new prompts from scratch (just follow best practices directly)
• The prompt is working well and the user hasn't identified issues
