Report #31392

[architecture] Agent generates toxic or off-topic content that poisons the next agent's context window

Implement output guardrails \(independent classifier models or rule-based checks\) at the agent handoff boundary, before the output is appended to the shared context.

Journey Context:
Input guardrails are common, but in multi-agent systems, the output of Agent A is the input to Agent B. If Agent A goes off the rails, Agent B will too. People try to fix this with longer system prompts, which is brittle. A separate small, fast classifier checking the output is more robust. Tradeoff: increased latency per handoff, but prevents context poisoning.
