“AI that can use tools”
A structured way for LLMs to request execution of external functions.

You get a lazy prompt and a goal. Rewrite it. We score your version against the habits of good agentic prompting — outcomes, constraints, tests, verification. 4 prompts. Clear it for XP — flawless runs earn a badge.
