// MISSION BRIEF

Your Mission

If AI output feeds a script, choose the output contract deliberately. Strict Structured Outputs provides schema adherence, while refusals and incomplete responses still need handling. Prompt-only JSON can add prose or fences, and JSON mode guarantees JSON but not schema adherence.

Battle teaser

The most reliable way to get valid JSON for a pipeline is:

  1. ARaise temperature so it is more creative with the format
  2. BAsk nicely for JSON and trust the string
  3. CParse whatever comes back with a regex and hope
  4. DUse strict Structured Outputs or strict JSON-schema mode where available, then handle refusals or incomplete responses and validate before use
Answers, scoring, hints, and the full battle stay sealed.
