[architecture] How to stop one agent's bad output from cascading through the whole chain

Isolate agents with bounded contexts and failure domains, validate outputs at every boundary, set per-step budgets/timeouts, and add circuit-breaker or rollback logic so a single bad handoff doesn't poison downstream agents.

Journey Context:
OWASP ASI08 \(Cascading Failures\) notes that a small error in one agent can amplify through planning, memory, and execution. In chains, a hallucinated API endpoint from agent A becomes 'ground truth' for agent B, which then crafts a broken or malicious call. The fix isn't just 'better prompts'—it's architecture: each agent owns a narrow contract, outputs are verified before crossing a boundary, and the orchestrator caps rounds and spend. Circuit breakers stop retries when failure rate spikes; compensating transactions undo partial work. The tradeoff is that tight isolation adds latency and complexity, but it converts catastrophic chain failures into localized retries.
