# Most Obvious Thing to Improve Prompt

> A single-line prompt for iterative code refactoring with AI

This is a minimalist prompt designed for Cursor and AI code assistants to spot easy refactoring wins. By asking for just the single most obvious issue across a set of files, you can incrementally improve code quality without overwhelming the model or introducing large bugs.

## The prompt

Prompt: "Within these X files, tell me the single most obvious thing that can be done better."

Usage: point it at a set of files, apply the fix it suggests, then repeat the prompt. Doing this often keeps the codebase clean and makes AI less frequently stuck.

## What it is for

- Clean up messy files before committing code
- Identify easy refactoring opportunities across a small group of files
- Prevent AI coding assistants from hallucinating by keeping review scopes narrow

## Key points

- Scopes AI context down to a specific set of active files
- Forces the assistant to prioritize only the single highest-impact fix
- Designed to be repeated iteratively after applying each suggestion
- Helps reduce code complexity and AI confusion over time
