Why AI Agents Fail at Real Work: It Is Not the LLM, It Is the Harness Shortage

Understanding why agents work in PoC but never reach production — through the design of purpose, authority, memory, stop conditions, recovery paths, and audit trails

The primary reason enterprise AI agents fail is not model performance alone. The essence of the failure is letting AI act without a harness that encloses purpose, authority, memory, quality, stop conditions, recovery paths, and audit trails.

Gradient Boosting for Enterprise Decision Prediction: XGBoost and LightGBM as the Decision Layer of Agentic Companies

Why enterprise data is often tabular and how gradient boosting ensembles support approval prediction, risk scoring, and outcome estimation

While deep learning dominates many unstructured tasks, enterprise decision data is frequently tabular: structured features describing decisions, agents, contexts, and outcomes. This paper formalizes gradient boosting (XGBoost/LightGBM) as the Decision Layer (Layer 2) of the agentic company stack, details feature-engineering patterns for enterprise decision tables, and introduces SHAP-based explainability workflows for governance audits. Across evaluated datasets, the approach achieved 91.3% approval-prediction accuracy, 0.94 AUC on risk scoring, and full SHAP traceability integrated with MARIA OS responsibility gates.
