Prompt Refiner

What this skill does

This skill takes a rough or underperforming AI prompt and rewrites it to be clearer, more specific, and more likely to produce consistent, high-quality output from a language model. It identifies the root causes of vague or ineffective prompts — missing context, absent output format specs, ambiguous instructions — and systematically addresses each one. It also explains every change so you can learn the principles, not just get a one-time fix.

Use this when your prompts produce inconsistent results, when the model frequently misunderstands what you want, or when you're building a prompt that will run in production.

How to use

Claude Code / Cline

Copy this file to .agents/skills/prompt-refiner/SKILL.md in your project root.

Then paste your prompt and ask:

• "Use the Prompt Refiner skill to improve this prompt."
• "Refine this system prompt using the Prompt Refiner skill — it's producing inconsistent outputs."

Include what the prompt is for (the model it targets, the task, what's going wrong with current outputs) to get more targeted improvements.
