LLM Agent Evaluation

We build the evaluation harness that tells you whether your Large Language Model (LLM) agent is getting better or worse — golden datasets, regression gates and metrics wired into CI, so "it feels fine" becomes a number you can trust.

What we build & measure
  • 01

    Golden datasets

    Representative, labelled cases drawn from your real traffic — the ground truth every future change is measured against.

  • 02

    Metrics that mean something

    Task-appropriate scoring — accuracy, faithfulness, safety, latency and cost — instead of a single misleading number.

  • 03

    Regression gates in CI

    Evals that run on every prompt, model or pipeline change and block a merge that makes the agent worse.

FAQ

LLM evaluation, answered

Why do we need evals?

Without them, a prompt tweak or model upgrade can quietly degrade quality and you'd never know until users do. Evals turn that into a gate.

How do you build a golden dataset?

From your real inputs and expected outcomes, labelled and version-controlled, so it reflects the work your agent actually does.

Can this run in our CI?

Yes — the harness is built to run in your pipeline and block regressions, and it's yours to keep and extend.
