AI Prompt Templates are pre-written instruction sets that shape how AI assistants behave in your projects. They come in many forms — .cursorrules files for Cursor, SYSTEM_PROMPT.md for Claude, .github/prompts/ for Copilot, and .windsurfrules for Windsurf. A good prompt template encodes coding standards, architectural decisions, and team conventions so every AI-generated response follows your project's style. Unlike Skills (which are Claude-specific), prompt templates work with any AI assistant.
