AI Coding Assistant Prompts

AI coding assistants like Cursor, GitHub Copilot, and Claude Code have transformed how developers write software, but their output quality depends heavily on how you configure and prompt them. A vague instruction like "fix this bug" produces very different results than a prompt that includes the error message, relevant context, and the expected behavior. The gap between mediocre and excellent AI-assisted coding is almost entirely about prompting.

Each coding assistant has its own configuration layer -- Cursor uses .cursorrules files, Claude Code reads CLAUDE.md, and Copilot supports custom instructions. These files act as persistent system prompts that shape every interaction. Getting them right means your assistant understands your codebase conventions, preferred libraries, testing patterns, and code style from the start, without you repeating yourself in every prompt.
