Copies 1 skill into each app's skills folder (Claude Code: ~/.claude/skills), after checking every file against nidhinjs/prompt-master at commit 2bd9251. Nothing else on your computer changes. To undo it, run the terminal command with --uninstall at the end; that also removes what the app added.

Then start a new session in your AI app and ask for the work in plain words; it picks the skill from its description. In Claude Code you can also type /prompt-master:prompt-master.

See it in use

One real session, replayed step by step: the request, each step at the moment it happened, and the answer, unedited. Long waits are shown faster, with the real time in the corner. Sample notes invented for this example: Acme Notes is a fictional note-taking app, and its support lead and the feedback are made up.
The result
my-prompt-fixed.mdWhat the session produced: my-prompt-fixed.md, the file the session saved.

One rewritten prompt ready to paste into ChatGPT, with a note on which problem each rule fixes.

my-prompt-fixed.md, the file the session saved.

Try it

After installing, start a new session and say: Here is a prompt I use with ChatGPT that gives unreliable results (my-prompt.md). Rewrite it so the output has the same shape every time and nothing is made up.

What else it can do, and its limits
  • Writes or fixes one prompt at a time for a named AI tool, ready to paste
  • Covers chat models (Claude, ChatGPT, Gemini, Grok, open models), coding agents (Claude Code, Cursor, Copilot), app builders, image, video, voice and workflow tools
  • Adds evidence and format rules where a prompt invents facts or drifts in shape
  • Asks up to 3 questions when the target tool or goal is unclear
  • Model names and settings change quickly: without web access it says when model details are unverified
  • Writes the prompt only; you run it in the other tool and check the first results

Sample input Recorded Oct 24, 2026 in Claude Code 2.1.308 with Sonnet 5.5. The video replays that session; nothing in it was acted or edited.
