Report #77909

[architecture] Agent calls the wrong tool or sub-agent due to ambiguous naming in the registry

Enforce strict, unique namespacing for all tools and agents \(e.g., finance\_db\_query vs hr\_db\_query\), and dynamically filter the tool list passed to each agent to only what it strictly needs.

Journey Context:
When an orchestrator gives an agent access to 20 tools or sub-agents, LLMs suffer from tool selection degradation, often picking similarly named tools \(e.g., send\_email vs send\_email\_draft\). This is a form of accidental impersonation. The fix is two-fold: strict namespacing to reduce semantic overlap, and programmatic least-privilege \(only passing the 3-4 tools an agent actually needs for its specific step\).
