What Are Prompts?
Prompts are reusable instruction templates exposed to MCP clients, so an AI assistant can pull a vetted prompt instead of everyone re-writing the same instructions by hand. They live in a shared library independent of any single server, and can be linked into as many servers as you want.

A prompt can use {{argumentName}} placeholders — Arthur automatically detects those and exposes them as arguments the AI client fills in.
