Module focus 

Focus — A focused LLM call.

Each Focus instance is bound to a system prompt and dedicated to one specific judgment question. Callers only need to provide input and the expected return type; the framework handles LLM invocation, JSON parsing, and timeouts.

Design Philosophy

Throwing all judgments at the LLM at once overwhelms it. Especially for generalized concerns, we need to decompose — the LLM should focus on one thing at a time, keeping it simple enough to handle. If the business decomposition is good, even a weak model can do one thing well.
