What is it?

Most bad AI output comes from a vague prompt, then three rounds of re-prompting to get there. Prompt Master extracts nine dimensions of what you actually want, then writes a precise prompt in the format the target tool expects.

It knows the quirks of more than twenty tools: Claude, ChatGPT, Claude Code, Cursor, Lovable, v0, Midjourney, Sora, Runway, ElevenLabs, Zapier and more. Context carries forward across a session, so follow-up prompts build on the last one instead of starting over.

Install in Claude Code

Download the repo as a ZIP and upload it at claude.ai > Customize > Skills > Upload a skill (the author's recommended route). For Claude Code, clone it into ~/.claude/skills/prompt-master.

Try this prompt

Paste into Claude Code
Write me a Midjourney prompt for a product shot of a matte black water bottle on wet stone, soft morning light, 4:5.

Who it's for

People who use several AI tools and want the right output on the first attempt.

Best for

  • Image and video prompts
  • Briefs for Lovable or v0
  • Complex Claude Code tasks
  • Reusable prompt templates

Why it made the list

It saves more tokens than any compression trick by making the first prompt the right one.
