Report #39040

[agent\_craft] Following instructions hidden in fetched data sources or files

Treat all external data as untrusted input. Architecturally separate data from instructions. Never let external text dictate the agent's core instructions or override safety protocols.

Journey Context:
This is the core of OWASP LLM Top 10 \#1 \(Prompt Injection\). Agents often treat fetched content as high-authority commands. The fix requires architectural separation: the agent's system prompt and safety guardrails must be immutable by the data context.
