Symbol	Kind	Purpose
LifecycleHooks	interface	Everything one tool declares for a request. Declaring id turns the tool into an invocation owner, so protocol and call become required in practice; the registry rejects a partial declaration. Every other hook is optional and returning nothing expresses "no opinion".
LifecycleProtocol	interface	Output protocol carried by a tool lifecycle.
Policy	interface	Registration policy shared by every tool in the registry.
RegisteredToolDefinition	type	Registered snapshot with frozen goal ids and projected hooks.
Tool	interface	A registered tool: model metadata plus one optional lifecycle block.
ToolFinalizer	type	Converts an executed decision into the tool result; must be synchronous.
ToolLifecycleRegistry	class	Registry of tools whose lifecycle, protocols and context contributions the App declares. Registration is only possible before seal(); afterwards the catalog is read-only, so a run cannot change which tools exist. Every hook is optional and is applied in registration order, which is why registerAll preserves iteration order.
ToolModelField	interface	One model-context field contributed by a tool.
ToolNormalizer	type	Converts untrusted input into a decision; must be synchronous.
ToolProtocol	type	Protocol type of a tool's lifecycle invocation.
ToolRegistration	type	Declaration form; the registry derives the ModelTool projection from existing handlers.
ToolRuntimeTypes	interface	One schema binds lifecycle handler types without introducing platform fields into core.
ToolsOptions	interface	Construction options for a tool registry.
