Right, that gap is the paper's own point. It claims an artifact (editable skill files), not that the agent acts on the judgment, and calls it the behavioral fidelity frontier, with no fidelity eval.

Your Python pipeline and TypeScript API can't call each other. That's not a tooling problem, it's architectural.

AI agents bottleneck accelerated 208x by classical operators

The thing slowing down every AI agent just got 208× faster.
— AlphaSignal AI (@AlphaSignalAI) 1 juin 2026
For years, speeding up AI meant making the language model itself run faster.
But agents changed the bottleneck.
They lean on older tools like clustering and search to verify their work.

A new GEPA visualizer shows an LLM optimizing its own prompts in real time.

They reduce every run to a single score and call it learning.
