# PAG Semantic Operation

> Name every external effect as one of the semantic operations (discover, read, search, analyze, extract, calculate, compose, validate, persist, execute, request a decision, report) with a uniform WITH / USING parameter clause and an INTO / arrow result binding, so the document names what it does and an adapter binding resolves how, and no host's tool name enters the document.
