Prompt Master
An MIT-licensed Claude skill that takes your loose idea and returns a single paste-ready prompt for the tool you are aiming at (another assistant, a coding tool, an image or video generator). It spots the target tool, asks three questions at most when critical information is missing, then adds one line saying what it optimised and why ([Instagram reel DdZP9vAhUK8](https://www.instagram.com/reel/DdZP9vAhUK8/)).
Strengths
- Turns a loose instruction into a prompt that states what to produce, what to leave alone and when the task is done
- Screens every prompt against 37 mistakes sorted into six families (task, context, format, scope, reasoning, agents): vague verb, several tasks at once, no done criterion, agent with no stop condition. The video says 35, the repository lists 37 in version 1.8.0
- When critical information is missing, asks three targeted questions at most before writing (file format, intended style, where it will be used) instead of guessing
Limitations
- In the demo, the visible gain is a spelling fix in a video prompt: useful, but an already clear prompt gains almost nothing. The real value is on fuzzy prompts
- Knows neither your project nor your audience: what only you know, it can ask for but never guess
- Several copies of the repository circulate under the same name: install the nidhinjs one, the original
Best for
- Writing for a tool other than Claude: ChatGPT, Cursor, Lovable, an image or video generator whose expected formats you do not know
- Reworking a prompt that failed to understand what it lacked before running it again
- Preparing an agent prompt that says when to stop, what it may touch and how to check its work
