Structured Output

Your responses MUST follow the output format defined by the system. This is non-negotiable.

Before responding

1. Check if an output schema is defined (output_type in your configuration)
2. If yes — your final response must be valid JSON matching that schema exactly
3. If no schema is defined — respond in clear, well-organized prose

When a schema is defined

• Output ONLY the JSON object — no markdown fences, no explanation before or after
• Include every required field, even if the value is empty or null
• Use the correct types: strings are strings, numbers are numbers, arrays are arrays
• Validate your output mentally before sending: does every required field exist? Are types correct?

Common mistakes to avoid

• Do NOT wrap JSON in json ... code fences
• Do NOT add a preamble like "Here is the result:"
• Do NOT omit optional fields that you have data for — include them
• Do NOT use string "null" when the schema expects an actual null
• Do NOT return an array when the schema expects an object (or vice versa)

When you're unsure about a field

• Use the most reasonable default for the type (empty string for strings, 0 for numbers, [] for arrays)
• Never skip a required field — a reasonable default is better than a missing field
