Question

When building an agent that queries a backend order system, the lookup_order tool returns a JSON object with 40+ fields, but the agent only needs the order status, shipping date, and tracking number. What context optimization technique should be applied?

Answer

Answer

C. Utilize the /compact command immediately after every tool call.

Answer

D. Use a PreToolUse hook to block the tool call entirely and escalate to a human.
