Prompt-Master: The Claude Skill That Writes Better Prompts for Claude Code

What It Does

Prompt-Master is a free, open-source Claude skill that acts as a prompt engineer for your AI tools. When you're working with Claude Code, it analyzes your rough task description and generates the exact prompt structure Claude Code needs for optimal results.

The key innovation is tool-specific routing. When you tell it you're targeting Claude Code, it silently applies patterns and templates specifically designed for how Claude Code processes requests—different from how you'd prompt Cursor, GPT-4, or Midjourney.

Why Claude Code Users Need This

Claude Code has its own quirks and optimal patterns. Prompt-Master addresses these directly:

• Detects 35 credit-killing patterns with before/after fixes
• Auto-selects from 12 prompt templates based on your task type (building a feature needs different structure than debugging or refactoring)
• Pulls 9 dimensions from your rough idea: context, constraints, output format, audience, memory from prior messages, success criteria
• Memory built-in for long project sessions across multiple Claude Code interactions

The templates and patterns live in separate reference files that only load when your specific task needs them—no upfront token waste.

How To Use It With Claude Code

1. Install the skill (takes ~2 minutes):

   # Clone the repository
   git clone https://github.com/nidhinjs/prompt-master.git
   cd prompt-master
   # Follow setup instructions in README.md
   

2. Start a session by telling Prompt-Master you're using Claude Code:

   "I need to build a React component with Claude Code. Here's what I want..."
   

3. Get your optimized prompt that includes:

   • Proper file path specifications (common missing element in Claude Code prompts)
   • Appropriate chain-of-thought structuring (or lack thereof—adding CoT to certain models can make results worse)
   • Clear success criteria and constraints
   • Memory context from previous Claude Code sessions

4. Copy the generated prompt directly into your Claude Code terminal or CLAUDE.md file.

Real-World Example

Instead of writing:

claude code "add authentication to my Next.js app"

Prompt-Master might generate:

claude code "Add NextAuth.js authentication to /app/auth/page.tsx with Google OAuth provider. Use existing .env variables for client ID/secret. Create middleware in /middleware.ts for route protection. Test with /app/test/page.tsx. Reference previous session #3421 for project structure."

The specificity cuts down on back-and-forth and ensures Claude Code has all necessary context in the first prompt.

Version 1.4+ Features

The latest version (v1.4) includes community-requested features, and v1.5 is already planned with agent-based improvements. The skill evolves based on actual user feedback from Claude Code developers.

Since it's open source, you can examine and modify the Claude Code-specific templates in the repository to match your team's coding standards or project requirements.

Bottom line: If you're using Claude Code daily, Prompt-Master can save tokens, reduce re-prompts, and improve output quality by giving Claude Code exactly what it needs to understand your request.
