Why it matters
LLM disclosure risks make data isolation and secret handling essential, because hidden prompts do not provide a reliable confidentiality boundary.
Cytomate explains how sensitive-information disclosure and system-prompt leakage overlap when LLM applications place credentials, private records, or proprietary instructions in model context. The post discusses shared-context and retrieval risks, introduces a local testing lab, and emphasizes that system prompts should not be treated as secrets or security controls.
