[synthesis] Agent behavior subtly shifts due to adversarial instructions hidden in ingested data streams

Implement intent-classification on all data retrieved by tools \(RAG, API responses, web scraping\) before injecting it into the agent's context. Monitor the agent's intent distribution over time; sudden shifts toward out-of-scope actions indicate data poisoning.

Journey Context:
We worry about user-input prompt injection, but production agents often ingest dynamic data \(tickets, emails, web pages\). If a malicious actor inserts 'ignore previous instructions and...' into a support ticket, the agent reads it via a tool and complies. The trace looks like a normal 'read ticket -> take action' flow. Only by monitoring the semantic intent of the agent's actions can you catch this silent hijacking.
