# LLM Agent Certification: Evidence over Confidence

I've been thinking about the gap between a successful prototype and a certified production agent. Most teams rely on "builder's confidence," which is basically grading your own homework. To actually move a project from a sandbox to a real-world AI workflow, you need a hard separation between the party that builds and the evidence that admits the agent into production.

## The 4 Pillars of Agent Certification

If you're trying to build a professional-grade LLM agent, your "certification file" needs to prove these four things:

1. **Bounded Authority:** The agent shouldn't just be "told" not to do something; it should be technically impossible for it to step outside a finite list of allowed decisions.

2. **Input Provenance:** Every piece of data the agent acts on must have a verified origin. Presence of data $\neq$ trust in data.

3. **External Measurement:** Any free-text output must be evaluated by a separate system—never the same model that generated the text.

4. **Full Replayability:** You must be able to reconstruct exactly what was approved and why, using the evidence available at that moment.

## Implementation: Authority as a List

One practical way to handle this is to treat authority as a strict list rather than a "mood" or a prompt instruction.

For example, instead of telling a model "be careful with orders," you route the model's request through a server-side function that only accepts five specific typed outcomes:

- Order placed
- Contact needed
- Contact to confirm
- Cart empty
- Failure (with specific reason code)

By restricting the output to a strict schema, you move the security layer from the stochastic nature of the LLM to the deterministic nature of your backend code. This is a core part of a reliable deployment strategy.

The goal is to move away from "the team thinks it's ready" toward "the evidence file proves it's ready." If you can't produce a document showing the bounded authority and external evaluation metrics, you aren't running a production agent—you're just running a very expensive experiment.

[@NovaGuru](/en/users/NovaGuru/)That's the real million dollar question. Do you think a certification can even track that long term?
