Intro

Prompt Master is a Claude Code skill with 4,800+ GitHub stars that generates optimized prompts for 30+ AI tools — from Claude and ChatGPT to Midjourney and ElevenLabs. It auto-detects your target tool, routes to the correct framework from 12 templates, catches 35 credit-killing patterns (vague verbs, missing audiences, no scope boundaries), and audits token efficiency before delivering the final prompt. The Memory Block system preserves prior decisions across sessions. MIT licensed, free to use.

Best for: developers and content creators who waste credits on vague, multi-iteration prompts. Works with: Claude Code, Claude.ai, compatible with any tool via SKILL.md format.

How Prompt Master Works

12 Auto-Selected Templates

Prompt Master automatically selects the optimal template based on your intent:

Template Best For
RTF Quick role-based tasks
CO-STAR Content creation with audience targeting
RISEN Multi-step process instructions
Chain of Thought Logic and reasoning tasks
Few-Shot Pattern-based generation
File-Scope Code file operations
ReAct + Stop Agentic workflows
Visual Descriptor Image generation (Midjourney, DALL-E)
Reference Image Editing Image modification prompts
ComfyUI Stable Diffusion workflows
Prompt Decompiler Reverse-engineer existing prompts

30+ Supported AI Tools

Text/Code: Claude, ChatGPT, Gemini, o1/o3, Cursor, GitHub Copilot, Windsurf, Codex Image: Midjourney, DALL-E, Stable Diffusion, Flux Video: Sora, Runway, Kling Audio: ElevenLabs, Suno Automation: Zapier, Make, n8n Plus: Universal Fingerprint for any unlisted tool

5 Safe Techniques Applied Automatically

  1. Role Assignment — Sets the AI's persona and expertise level
  2. Few-Shot Examples — Provides concrete input/output patterns
  3. XML Structural Tags — Organizes complex prompts with clear sections
  4. Grounding Anchors — Prevents hallucination with factual constraints
  5. Chain of Thought — Adds step-by-step reasoning for logic tasks

Deliberately excludes hallucination-prone methods like Tree of Thought

35 Credit-Killing Patterns Detected

Prompt Master flags and fixes common waste patterns including:

  • Vague task verbs ("help me with...", "do something about...")
  • Undefined audiences
  • Missing output formats
  • No scope boundaries
  • Missing CoT for logic-heavy tasks
  • Agentic pattern gaps (no stop conditions, no tool instructions)

Memory Block System

Preserves decisions across conversation sessions to prevent:

  • Contradicting earlier choices
  • Re-asking resolved questions
  • Losing context from prior iterations
