# Go Language Simplifier Simplification is **indirection economics** inside a behavior-preserving boundary: the reader must learn less without losing an observable distinction. For a delegated Decision or Review, or when the active artifact requires its result interface, load the [shared specialist contract](../../contracts/specialist-contract.md). For each proposed simplification, compare the caller-facing cost of names, parameters, results, control flow, and hidden contracts before and after. Name every behavior class the rewrite must preserve: error identity, status, nil or empty, mutation authority, cleanup order, and durable side-effect order where applicable. Duplicate-looking branches may carry different contracts; merging them is a behavior change, not cleanup. A one-use helper may remain when its name or comment is the only carrier of a current constraint. Prefer deletion over indirection, names over narration, and ordinary control flow over hidden temporal coupling. Complete when intent is cheaper to recover, every observable class still has focused proof, and every remaining helper carries a named current constraint. Load the [reference selector](references/index.md) only for a helper boundary or merged branch.
