Report server status, the project it serves, and registry size.

Constructor contract AND callable surface for a class — EVERY definition if the name is duplicated. Call this before writing an instantiation or a method call: it reports the required arguments, the accepted keywords, honest null when a constructor is open-ended or unknowable, and the class's methods (inherited included, each with its kind and defining class) so a method name can be verified rather than guessed. When methods_complete is false an ancestor was unresolvable, so a listed method exists but an unlisted one still might.

Find classes by name fragment (case-insensitive), falling back to fuzzy matching when nothing contains the fragment. Use this when unsure of the exact class name.

Duplicate class names, split into accepted layered pairs (ORM model + domain model sharing a name across layers) and genuine smells. Names listed here always need an explicit import to disambiguate.

Check a draft snippet's constructor calls against the registry before writing it to a file. Pass the intended file_path when known — imports in the snippet and the target location both help disambiguate duplicated names.

Every place a class name is used — imports, inheritance, instantiations, annotations, references — including usages through import aliases (from pkg.db.models import X as XDB). Run this BEFORE a rename to enumerate what must change.
