GET /agent-test/mock-targets enumerated Functions, SecondaryFunctions and McpTools only, so an agent whose whole toolset comes from utilities -- Lessen Work Order Summary, Property Summary -- reported no callable functions at all. Utilities are expanded into SecondaryFunctions by BasicAgentHook.OnAgentUtilityLoaded at conversation time, and IAgentService.GetAgent, which is what every caller here holds, is a plain repository read that never runs that hook.

Cost of the gap: a case authored against such an agent blocks its own tools on the first run, and the case editor's tool picker has nothing to offer.

The filter mirrors the hook -- a disabled utility is off, only a util- prefixed name is ever loaded as a function, and the real FunctionDef is read off UtilityAssistant rather than the agent's own declaration. VisibilityExpression is deliberately not mirrored: it needs the conversation's render data and cannot be evaluated against a stored agent, so a conditionally-visible utility is offered and may turn out not to load.
