Replacing manual prompt vibe checks with continuous evaluation pipelines. We engineer deterministic scoring rubrics, regression datasets, and live trace observability in Braintrust so enterprise agents never degrade in production. ## The benefits of Braintrust Evals Why enterprise engineering leaders standardize continuous agent evaluation and CI/CD gates on Braintrust. ### Automated CI/CD regression gates before deploy Every prompt edit, model swap, or tool schema change runs automatically against golden production datasets in Braintrust, blocking regressions before code reaches users. ### Logs as Proprietary Asset Real-world edge cases and production anomalies captured via live telemetry are converted in one click into permanent regression test cases. ### Code-level scorers over subjective LLM judges Combining deterministic Python assertion scorers with calibrated rubric evaluators to measure accuracy, latency, and token cost across every workflow step. ## Architecture framework The three essential layers connecting Braintrust evaluation pipelines to deterministic agent execution. ### Braintrust Evaluation Engine Golden evaluation datasets, automated CI/CD pull-request scoring, and real-time latency and cost telemetry across models. ### LangGraph State Core Finite state machines and dynamic business ontologies that expose every node transition for granular step-by-step evaluation. ### Guardrails & Audit Suites Deterministic schema validation, SQL query guardrails, human-in-the-loop checkpoints, and continuous regression testing. ## From POC to production Our practical approach to ensuring agent initiatives advance beyond prototypes into mission-critical systems: Technical, architectural, and business feasibility assessment before writing code. Curating real enterprise edge cases into versioned Braintrust datasets and deterministic code-level scoring functions. Wiring Braintrust evaluation gates directly into GitHub Actions and LangGraph deployments to block hallucination regressions. Architecture documentation, evaluation test suites, and continuous knowledge transfer to your team. ## Tailored engineering for your enterprise stack No theoretical slide decks. We deliver working software and audited code that your company fully owns. ### Hugo S. Nascimento We advise CTOs, VPs of Engineering, and technical leaders on designing, auditing, and hardening agent architectures. From initial feasibility audits to complete code handover to your internal team, we deliver deterministic software that you fully own.
