Resilience Analysis Assesses error handling and isolation boundaries. Process 1. Trace error propagation — Map exception flow from tools to agent 2. Identify isolation — Sandbox mechanisms for dangerous operations 3. Catalog recovery — Retry logic, fallbacks, circuit breakers 4. Assess boundaries — What crashes propagate vs. are contained Error Propagation Analysis Questions to Answer 1. Does a tool exception terminate the agent? 2. Are LLM API errors retried automatically? 3. Is parsing failure (malformed output) recoverable? 4. What happens when state updates fail? Propagation Patterns Cras…
