Exercise 05 — Debug Looping Agent

Timebox: 30 minutes

Goal

Use buggy_agent.py to practice debugging an agent that keeps repeating the same failing tool call.

Work in

• buggy_agent.py

Tasks

1. Add an explicit iteration cap.
2. Stop repeating the same failing tool call forever.
3. Surface a clean failure when the tool keeps failing.
4. Log enough trace information to explain what happened.

Done when

• The script terminates cleanly
• The failure is visible and understandable
• The agent does not keep retrying the same broken step forever
