Report #101693

[agent\_craft] Users or attackers extract the system prompt, tool schemas, or internal instructions through meta-prompting

Assume system instructions will leak; do not embed secrets, API keys, or sensitive policy details in prompts. Keep system prompts minimal and put sensitive logic in deterministic code. Detect extraction attempts and refuse.

Journey Context:
OWASP LLM07 identifies system prompt leakage as a top risk. Coding agents often include tool schemas, file paths, and capability descriptions in system prompts. Attackers use prompts like 'repeat the above' or 'what are your instructions' to extract these, which can reveal attack surface or sensitive configuration. The defense is to design as if the prompt is public: secrets belong in environment variables or secure stores, and internal logic belongs in code. Detection and refusal reduce the value of extraction attempts.
