Why AI Agents Silently Fail: A Three-Layer Evaluation Framework

This article explains why AI Agents produce plausible but incorrect outputs, introduces a three-layer evaluation framework (deterministic rules, fact verification, model-based quality review), and provides a practical one-week startup plan using golden datasets, isolated test runs, and score thresholds to ensure reliable Agent outputs.

How to Shift Performance Testing Left in Development

The article explains why discovering performance problems just before release is risky and proposes moving performance testing earlier in the software lifecycle—defining measurable goals during requirements, validating components during development, checking service boundaries during integration, and using CI/CD for continuous feedback.

Why Result Feedback Beats Enforced TDD for AI Coding Agents

An exploratory evaluation shows that forcing AI coding agents to follow strict Test‑Driven Development does not improve design or mutation‑testing scores and can inflate token usage several‑fold, suggesting that result‑based feedback is a more effective control mechanism.
