Agent Evaluation

The Agent Detective Tool Is Broken. Here’s What It’s Really Telling You.

The new Agent Detective tool promises to find which agent broke in a workflow. But the top comment reveals a fatal flaw: ‘broke’ is subjective. The real value isn’t detectionβ€”it’s forcing teams to define what ‘good’ looks like. That conversation reveals deeper design flaws than any bug ever could.

Stop Obsessing Over Accuracy. Your AI Agent Is Bleeding You Dry.

Developers obsess over accuracy while ignoring costβ€”but the real bottleneck to production AI is cost predictability. Maverik gives you a systematic way to benchmark agent performance and predict costs, so you can decide whether a 5% accuracy gain is worth a 10x cost increase. Stop flying blind.

Your AI Eval Suite Is a Lie. Here’s What’s Actually Keeping Developers Up at Night.

Smevals, a collaboration between Simon Willison and the Superpowers plugin developer, isn’t just another eval tool β€” it’s a lightweight sanity check that evaluates your evaluators themselves. Most AI teams are flying blind, relying on manual tests disguised as ‘evaluation.’ Smevals sits in the gap between expensive enterprise suites and guesswork, giving solo developers and small teams a cheap, fast way to validate prompt changes before they become public embarrassments.

Your AI Agent Will Fail in Production. Here’s How to Stop It Before It Costs You Everything.

Most teams treat AI agent evaluation like a final exam: pass a few test cases, ship, and pray. But agents are non-deterministic, black-box, and cascade errors. The real framework turns evaluation into a closed-loop system where every failure generates regression tests, root-cause labels, and repair tickets. This is the only way to survive production.
