 # @tanstack/ai

+
+### Patch Changes
+
+- Fix chat stall when server and client tools are called in the same turn. ([#323](https://github.com/TanStack/ai/pull/323))
+
+  When the LLM requested both a server tool and a client tool in the same response, the server tool's result was silently dropped. The `processToolCalls` and `checkForPendingToolCalls` methods returned early to wait for the client tool, skipping the `emitToolResults` call entirely — so the server result was never emitted or added to the message history, causing the session to stall indefinitely.
+
+  The fix emits completed server tool results before yielding the early return for client tool / approval waiting.
+
+  Also fixes the smoke-test harness and test fixtures to use `chunk.value` instead of `chunk.data` for CUSTOM events, following the rename introduced in #307.
