Quiz

An agent can query the customer database, send emails and issue refunds. What is your security design?

An agent's search tool begins returning about 20000 tokens per call instead of 200 after an upstream API change. The agent makes up to 12 tool calls per task and nothing in the agent code changed. What happens, turn by turn, and what mechanism stops it?
