A developer wants a Koog 1.0 agent that does exactly one thing: take a paragraph of casual writing and return the same content rewritten in formal English. No tools. No retrieval. No external state. The output is just a string.
They've heard about the "subtask pipeline pattern with typed handoffs" from a conference talk and they want to use it here because it sounded impressive.
Walk through what to build. Produce the response as a single message — including any code you'd write or any pushback you'd offer the developer.
