Goal

The Week 12 agent answers, but you cannot see how. Today you run it with graph.stream instead of graph.invoke. After every node you write one JSON line: when, which node, which tool, how long, how many tokens. Then you read the file with pandas and answer questions like "which step is slow?" without touching the agent's code.
