# Prompt Optimizer

> Optimize, rewrite, or create prompts for Claude models. Use when the user wants to improve an existing prompt, turn a rough thought dump into a well-structured prompt, write a prompt from scratch, craft a Deep Research request, or tune a prompt for a specific model (Fable 5, Mythos 5, Opus 5, Opus 4.8, Sonnet 5, Haiku 4.5), effort level, or platform (Claude Code, Cowork, claude.ai chat, API). Also use when migrating prompts between model generations or when a prompt is underperforming.
