Stop Wasting Claude Code Credits: How prompt-master Crafts Optimized Prompts Automatically
If you're using Claude Code daily, you know the frustration: you write a prompt, it misunderstands, you re-prompt, and credits burn away. The open-source prompt-master Claude skill fixes this by acting as a prompt engineer inside your chat.
What It Does
Prompt-master is a free Claude skill that analyzes your rough task description and writes the exact, optimized prompt for your target AI tool. For Claude Code users, this means:
- Automatic Tool Detection: It silently detects you're targeting Claude Code and routes to the specific prompting approach that works best for its agentic, file-aware nature.
- 9-Dimensional Analysis: It extracts context, constraints, output format, audience, success criteria, and more from your vague idea so nothing critical is missed.
- 35 Credit-Killing Patterns Fixed: It detects and corrects common mistakes like forgetting to specify file paths (crucial for Cursor/Claude Code workflows), trying to build an entire app in one monolithic prompt, or incorrectly adding chain-of-thought reasoning to models where it hurts performance.
- 12 Auto-Selected Templates: It chooses the right template structure based on your task. Prompting Claude Code to build a feature uses a completely different template than writing an email or generating documentation.
- Efficient Loading: Templates and pattern fixes live in separate reference files that only load when your specific task needs them—no upfront token bloat.
Why Claude Code Users Need This
Claude Code operates differently than a general chat model. It's an agentic tool that reads your workspace, executes commands, and writes files. A bad prompt can cause it to:
- Misunderstand the scope and edit the wrong files.
- Use an inefficient, token-heavy approach.
- Require multiple back-and-forth clarifications, burning through your credit balance.
Prompt-master is trained on these specific failure modes. Its templates for Claude Code inherently include best practices like scoping the task to specific directories, defining clear success criteria, and structuring the request for sequential agentic execution.
How To Set It Up & Use It
The skill is configured as a Claude Desktop skill. Here's the quick setup:
Clone the repo:
git clone https://github.com/nidhinjs/prompt-master.gitAdd it to Claude Desktop: Open Claude Desktop settings, navigate to the "Skills" section, and add the local path to the cloned
prompt-masterdirectory.Use it: In any Claude chat (including within Claude Code's chat interface), describe your task in plain English. For example:
"I want to add a user authentication middleware to my Express app in theserver/middleware/folder."The skill activates, analyzes your request, and outputs a refined, actionable prompt ready for Claude Code to execute. You then submit that prompt.
The Bottom Line
This isn't a generic prompt helper. It's a specialist for AI tools. For Claude Code, it translates your intent into prompts that respect the tool's architecture, avoid known pitfalls, and get you to working code faster with fewer credit-consuming iterations. Version 1.4 is live now, with agent-based features planned for v1.5.
