**Bug Description**

In the Temporal Policies banking assistant UI, one of the workshop instructions says "Transfer $500 from ACC-1001 to ACC-2003". However, the agent replies that it does not have a tool for a direct transfer. This is not documented in the workshop and creates confusion for attendees who expect the transfer to work.

**Expected Behavior**
Either the agent should have a transfer tool, or the workshop instructions should not include this test case (or should document the expected "no tool" response as expected behavior).

**Suggested Fix**
Update workshop instructions to either:
1. Add a transfer tool to the banking assistant, or
2. Remove this test case, or
3. Document the expected "no tool available" response and explain why (temporal policy blocks it)
