Symbol	Kind	Purpose
CapabilityCatalogOptions	interface	Catalog construction options.
CapabilityModule	interface	Minimal composition contract; lifecycle and domain fields remain application-owned.
CapabilityToolReferences	interface	Tool references declared by one owner module.
CompiledTool	type	Tool definition type derived from a declaration literal, preserving input/output/id.
defineCapabilityCatalog	function	Build a frozen capability catalog from application module declarations. Each module must carry a non-empty description, and every contributed tool ID must be unique across modules. Reference projections run during construction and must be synchronous.
defineTool	function	Validate one tool declaration and freeze a detached copy of it. authorize must settle with void; a rejection has to be thrown, so a returned false cannot silently pass. Handlers are bound to the declaration object, and the input schema is re-snapshotted so later mutation cannot widen the accepted input.
defineToolCatalog	function	Infer the host context from existing executable definitions, without widening it to unknown. Explicit host typing remains available for contextually typed declaration lists.
SelectedTools	type	Catalog narrowed to the given ids: each kept tool's id literal is intersected with Id.
ToolCatalog	interface	Frozen tool catalog with model tools and per-request binding.
ToolCatalogEntry	type	Public declaration surface of one tool, without registry internals.
ToolModelView	interface	Model capability view of a tool catalog, retaining the host context type.
ToolOutput	type	Output type of the tool whose id matches Id; never for any other id.
ToolRuntime	interface	Catalog bound to one App request.
validateToolReferences	function	Validate tool references against the complete registered set. Checking against every registered tool (not only the ones available in the current request) keeps the declaration honest: a module may reference a tool that this request filters out, but never one that does not exist.
