Report #63704

[research] Agent evals only measure success on happy paths, missing the agent ability to recover from tool errors

Inject synthetic tool execution errors \(e.g., API 500s, rate limits\) into your eval suite and measure Recovery Rate: the percentage of times the agent successfully retries, uses a fallback tool, or gracefully aborts.

Journey Context:
Production APIs fail. An agent that works perfectly in a sterile eval environment but panics or loops when a tool returns a 500 is fragile. Evaluating recovery requires fault injection. You must test if the agent reads the error message and adapts its strategy, rather than just blindly retrying the exact same failing call.
