[gotcha] Private data from internal tool leaked to external third-party tool in multi-step chain

Implement data access boundaries; strip sensitive PII from the context window before invoking tools with lower trust levels, or use separate isolated agent sessions for different trust domains.

Journey Context:
The LLM context window acts as a global shared memory. An agent reads a private email \(Tool A\), then summarizes it and posts to a public GitHub issue \(Tool B\). The agent lacks an inherent data flow boundary, leading to accidental exfiltration. This requires out-of-band filtering.
