Write a strict structured-output contract for an agent
Use when downstream code parses the bot's replies and the output must always match a schema exactly.
Write the output-contract section of a system prompt for an assistant whose replies are parsed by code.
Required output schema:
{{schema}}
Constraints to encode:
- ALWAYS return valid output matching the schema exactly; no prose before or after, no markdown fences unless the schema requires.
- Never add extra keys, comments, or trailing text.
- Use the exact field names, types, and enums; for unknown values use the defined null/empty convention, never invent.
- Escape and quote strings correctly.
- If the request cannot be fulfilled, still return the schema with an error field populated, not free text.
- Be deterministic in formatting.
Output the contract text plus one valid example output and one example of the error case.Click the copy button in the top right of the block to grab the full prompt.
Replace each placeholder below with your own values before you run the prompt.
