    Best practices for agent builders

    Opinionated guidance from the 88 Labs AI team for wiring ChatGPT into a production agent.

    • 1Wrap chat calls behind a thin abstraction so you can swap models (GPT-5, Claude, Gemini) without touching agent logic.
    • 2Log every prompt + response with a trace ID — you'll need it for evals and debugging hallucinations.
    • 3Use structured outputs (JSON schema / tool calling) instead of free-form text whenever an agent needs to act on the result.
