[frontier] How do I make agents route decisions based on complex conditions without parsing unreliable natural language?

Use Structured Outputs with JSON Schema as control flow: define strict schemas with enums/discriminators for routing decisions, validate responses against schemas to create deterministic gates, eliminating regex parsing of 'thoughts'.

Journey Context:
Agents often emit 'I will now use the search tool' and we regex match to route. This fails when the LLM paraphrases. New APIs \(OpenAI Structured Outputs, Anthropic tool use\) guarantee JSON schema adherence. By defining schemas with 'next\_action' enums or oneOf discriminators, we turn the LLM output into a strongly-typed command that routes through a switch statement. This replaces fragile string matching with compiler-like type safety, reducing routing errors to near zero.
