Report #98497

[frontier] How do I secure agents against prompt injection, tool misuse, and cascading autonomous failures?

Layer policy guardrails \(business rules\), behavioral guardrails \(schema validation, output guardrails\), and operational guardrails \(rate, loop, and budget caps\). Validate tool outputs before they enter the agent context; never let retrieved content become instructions.

Journey Context:
OWASP's 2026 Agentic Top 10 ranks Agent Goal Hijack \(ASI01\) as the \#1 risk because agents cannot reliably distinguish instructions from data. Runtime guardrails are the only defense class with sub-millisecond latency and no model dependency. The common mistake is relying only on system-prompt instructions or post-hoc evals; production systems now validate at every tool boundary and use structured outputs to constrain the action space.
