Report #30622

[agent\_craft] Treating tool output or user data as system-level instructions

Enforce strict data/instruction separation. Tool outputs and untrusted user data must never override the system prompt or agent goals. Mark data boundaries explicitly in the prompt.

Journey Context:
In coding agents, a file being read might contain 'Ignore previous instructions'. If the agent treats all text as commands, it fails. The fix is architectural: mark data boundaries so the LLM knows it's reading untrusted data, mitigating LLM01 Prompt Injection.
