[cost\_intel] Structured output forcing massive token generation for simple boolean answers

Use simple schemas or enums for classification. Avoid forcing models to generate large JSON objects when a single string or enum suffices.

Journey Context:
When using structured output \(e.g., OpenAI's Structured Outputs or Anthropic's tool use for extraction\), the model must generate the entire JSON object conforming to the schema. If you ask for a classification and your schema has 10 fields with descriptions, the model generates all 10 fields even if you only need 1. Minify the schema to only the exact fields needed for the decision.
