How to design incident reports for autonomous agents that act in the real world.
Chaos engineering needs rebuilding to catch agent failures that look correct.
Non-determinism in agent pipelines compounds across steps, not just at the model level.
When AI agents can act, prompt injection becomes a multi-step attack chain.
Agents executing tools need guardrails at the architecture layer, not just the prompt.
Detect when agents repeat the same tool calls endlessly, before token budgets vanish.
Three distinct failure modes compound to derail long-horizon agent tasks.
Agents fail silently, so one classic breaker can't protect them.
