Assemble the output contract of your feature

The final workshop gathers the course's decisions into a single document: the output contract for one feature of your product, ready for engineers to review. You assess it yourself against a checklist, then plan how to put it into practice over the next 7 and 30 days.

Lesson objective

By the end of this lesson, you will be able to assemble the full output contract of a feature in your product (consumers, mechanism, schema, validation, exceptions, version, 20 cases and thresholds), self-assess it and plan how to apply it over 7 and 30 days.

Topics covered

  • output contract
  • workshop
  • exit kit
  • action plan

What you will learn in this module

This lesson is part of the course Get reliable, product-ready AI outputs (JSON, schemas, function calling)

  • Diagnose where free-text output breaks a feature and decide which outputs require a contract.
  • Choose between instructions alone, JSON mode, structured outputs and function calling for a given need, and justify the choice.
  • Design an output schema (types, enums, required fields, nullable fields, descriptions, "unknown" values) where every field serves a consumer.
  • Specify validation (syntax, schema, business rules), retries, handling of refusals and truncation, and the fallback path.
  • Version and evolve an output contract without breaking its consumers, accounting for provider differences and the split of roles between PM and developers.
  • Build a set of 20 robustness cases and set acceptance thresholds before going to production.
