Report #3153

[architecture] Multiple agents registering the same tool causing duplicate execution or conflicting results

Bind tools to exactly one primary agent. If another agent needs the capability, it must request execution via a handoff to the primary agent rather than duplicating the tool definition.

Journey Context:
When multiple agents share the same tool \(e.g., a file writer\), the router might arbitrarily choose which agent executes the action. This breaks encapsulation and makes auditing impossible, as you cannot trace which agent's logic caused a side effect. By enforcing a single owner per capability, you create a microservice-like boundary. The router's job becomes matching intent to the owning agent, not matching intent to a detached tool.
