What does prompt-master do?
prompt-master is a skill that writes one ready-to-paste prompt for a named AI tool and turns on only when you ask for prompt work. It first confirms the target tool, quietly pulls out nine details such as task, output format, constraints and success criteria, and asks at most three questions. It then routes to tool-specific advice for Claude, GPT, Gemini, local models, coding agents like Cursor and Claude Code, and image or video tools. The output is a single prompt block plus a one-line note on the target and what was tuned. It strips credentials and drops requests for hidden chain-of-thought.
When should you use prompt-master?
Use it when
- You need a prompt for Midjourney or a video model
- Your coding agent prompt keeps drifting off scope
- You want an old prompt adapted for a new model
Skip it when
- You want Claude to do the task, not write a prompt
- You want a course on prompt techniques
Why it scores 66
Strongest on upkeep (100 of 100), weakest on adoption (32).
