Report #52770

[frontier] Router agents waste tokens and hallucinate routing decisions

Use structured generation libraries \(Outlines, Guidance, XGrammar\) to constrain the LLM output to a JSON Schema where specific enum values deterministically trigger downstream agents, eliminating fuzzy 'router LLM' prompts.

Journey Context:
Prompting 'Which agent should handle this?' is brittle and slow. By forcing the model to emit a specific token sequence \(e.g., \{"route": "billing\_agent"\}\) via regex constraints \(FSMs\), the orchestration becomes deterministic code, not probabilistic interpretation. This is 10x faster, eliminates 'maybe' routing, and guarantees valid JSON output for the next agent.
