Report #37059

[architecture] Agent uses the wrong tool because multiple sub-agents expose identically named functions in a shared namespace

Namespace all tool definitions with the agent's domain \(e.g., code\_search vs web\_search\) and strictly scope tool schemas to the active agent. Never merge tool schemas from multiple agents into a single LLM context.

Journey Context:
When an orchestrator hands off to a sub-agent, developers sometimes append the sub-agent's tools to the existing tool list to keep context. If both the orchestrator and sub-agent have a search tool, the LLM will unpredictably call the wrong one, leading to silent failures or infinite loops. Tool schemas must be strictly swapped during handoffs, not merged, and namespaced to eliminate ambiguity for the LLM's function calling mechanism.
