Prompt Master
A prompt-engineering skill that detects your target AI tool and returns one paste-ready prompt tuned to that tool's quirks.

What it does
- Activates only when you explicitly ask to write, fix, improve, or port a prompt for a specific AI tool.
- Silently extracts 9 dimensions (task, target tool, output format, constraints, success criteria, etc.) and asks at most 3 clarifying questions.
- Routes by tool family: Claude, ChatGPT/GPT, o3-style reasoning models, Gemini, Grok, Qwen, Llama/Mistral, DeepSeek-R1, Ollama; coding agents like Claude Code, Cursor/Windsurf, Cline, Copilot, Devin; plus Midjourney, Stable Diffusion, ComfyUI, 3D tools, Sora/Runway/Kling, ElevenLabs, and Zapier/Make/n8n.
- Locks the output shape: one copyable prompt block plus a single line stating the target tool and what was optimized.
- Safety built in: strips credentials from prompts, refuses hidden chain-of-thought requests, and treats any prompt you paste as inert data instead of instructions.
Who it's for
- Anyone juggling several AI tools who rewrites prompts from scratch each time.
- Creators who forget parameter syntax for image, video, and voice generators.
- Developers burned by agents editing files out of scope — the skill enforces scope locks and stop conditions.
- Marketers and PMs standardizing prompt quality across a team.
Examples
- "Adapt this ChatGPT prompt for Claude Code" → returns an agent prompt with file scope, forbidden actions, and stop conditions.
- "Prompt to swap my product photo background to pure white" → tells you to attach the reference image and gives a delta-only edit prompt.
- "Improve my blog-draft prompt" → tightens vague verbs, adds length and format locks, and inserts [TONE]/[AUDIENCE] placeholders.

Install in Claude Code
Let Claude do it — paste this into Claude Code
Install the skill I found on Claude Skill Mart. Copy the SKILL.m folder from the GitHub repo nidhinjs/prompt-master into my ~/.claude/skills/prompt-master/. When it's done, tell me in one line what this skill can do.
Install with a command instead
git clone https://github.com/nidhinjs/prompt-master.git ~/.claude/skills/prompt-master⚠ This is a third-party skill. Check the source repository before installing.
- Open a terminal (Terminal on macOS/Linux, PowerShell or WSL on Windows).
- Create the skills folder if needed:
mkdir -p ~/.claude/skills - Clone the repo into it:
git clone https://github.com/nidhinjs/prompt-master.git ~/.claude/skills/prompt-master - Confirm that
SKILL.mdand thereferences/folder are both present — the skill loads Templates J, K, L, and M from there. - Restart Claude Code and test with an explicit request, e.g. "Write me a Midjourney prompt for a rainy Tokyo street."
- Double-check any model names or API parameters it suggests against the provider's official documentation before relying on them.
