Still from the clip posted with this case; watch it in the original post on X.

Integrated Jev into SystemOne Tune so unlabelled example pools can be routed to fix agent tool-selection failures.

The original post

🎯 SystemOne Harness + Jev + GEPA = SystemOne Tune ⚙️ We have integrated these three technologies and released the “SystemOne Tune” optimisation layer. 🫧 If your agent fails to select the right tools or any other use case arises, direct it to an unlabelled example pool. Jev

Where this case fits

Filed under agents & workflows. In the pattern Jev is built for, the model answers a bounded question per step — and ordinary code acts on the answer, because the answer is already a value rather than a paragraph. Other posts in the same family are on the agents & workflows page.
