When Agents Fail
A recovery lab for agents that change real things
Your agent says it stopped. What did it actually do? A tool call times out, someone presses Stop, a result arrives after the goal changed, an approval gets used for something it never covered. This book takes those moments one at a time: each chapter names a failure, reproduces it in a small synthetic run, builds the code that handles it, and ends with an exercise you run on your own machine.
