prompt-master
A Claude skill that writes the accurate prompts for any AI tool. Zero tokens or credits wasted. Full context and memory retention
Prompt Master is a Claude agent skill that generates optimized, token-efficient prompts for over 30 AI tools including Claude, ChatGPT, Cursor, Midjourney, DALL-E, and autonomous coding agents. It analyzes user intent across nine dimensions, asks targeted clarifying questions, and automatically selects from 13 prompt templates to produce precise, context-aware prompts that eliminate wasted API calls. The skill includes specific routing logic for different AI models (Claude 5, GPT-5.6, o3, Grok, Gemini, DeepSeek-R1) and detects 37 common prompt anti-patterns that waste tokens and credits.
Key Features
Use Cases
- 01Generating precise coding prompts for Cursor, Windsurf, or Claude Code with exact file paths, scope boundaries, and stop conditions
- 02Creating optimized visual prompts for Midjourney, DALL-E, Stable Diffusion, or ComfyUI with proper parameters and negative prompts
- 03Debugging and refactoring existing prompts that produce inconsistent or wrong results across multiple attempts
- 04Building task briefs for autonomous agents (Devin, Claude Code, Manus) with defined starting state, target state, and approval gates
- 05Adapting prompts across different AI platforms while respecting each model's unique capabilities and syntax requirements
- 06Eliminating wasted API calls by front-loading all necessary context, constraints, and success criteria in a single prompt
