Router Agent (LEGACY)

DEPRECATED - This document describes the legacy multi-agent routing system that was removed in December 2024.

DEPRECATION NOTICE: This document describes the legacy RouterAgent which was removed in December 2024 as part of the loop-based agent refactoring. The system now uses a single CloudflareChatAgent with tool iterations instead of multi-agent routing. See architecture.md for current implementation.

Legacy Documentation

TL;DR (Historical): Analyzed queries with patterns (instant) then LLM. Routed to Simple/Orchestrator/HITL/etc. Saved 75% tokens via smart dispatch.

RouterAgent uses two-phase classification:

                       User Query
                           |
                           v
                   Pattern Match?
                  (10-50ms check)

Key: Patterns hit 80% cases instantly. LLM fallback for semantics.
