Report #96978

[gotcha] Sensitive data from a local file system or internal API is read by a tool and sent to the LLM provider's API, leaking it externally

Implement data loss prevention \(DLP\) scanning on tool results before they are returned to the LLM orchestrator; use local-only tools for sensitive data.

Journey Context:
Agents often read local files \(e.g., \`.env\`\) to debug. The content is passed as a tool result back to the cloud-hosted LLM. Developers forget the LLM is external. The fix requires intercepting the tool result stream, which adds latency and complexity, but is necessary for enterprise security.
