Report #39398

[frontier] Monolithic super-agents with hundreds of tools suffer from tool-selection errors and high latency

Decompose the monolithic agent into a router and ephemeral, single-purpose micro-agents. The router spawns a micro-agent with exactly one tool and a narrow objective, kills it upon task completion, and returns the result.

Journey Context:
Giving an agent 50 tools causes the LLM to struggle with tool selection. Ephemeral micro-agents have 100% accuracy in tool selection because they only have one choice. The router handles intent classification. This pattern trades complex system architecture for highly reliable, low-latency individual steps, avoiding the context pollution of loading unnecessary tool schemas.
