Diagnose and fix what the agent breaks
Everything real breaks, and panic is the expensive response. This part is the calm playbook: read the error, find the cause, and undo the damage safely, whether the bug is in the code or in the agent itself.
By the end of this part, you can:
- Read a stack trace and find where it actually broke
- Break an agent stuck in a loop and get it moving
- Bisect a regression down to the change that caused it
- Roll back safely when a fix makes things worse
