Bring your Friends and Framework

Your framework runs the agent; Jetty runs a separate grader runbook, stores the run, and scores it against an independent rubric. Because the grader is independent of the agent under test, you can swap frameworks, models, or providers and keep the exact same measuring stick.

Two worked examples, end to end:

• Eve + Jetty: Mount the @jetty/eve extension into a Vercel eve agent: live grading, a grade-steered experiment bandit, and an eval reporter. Catch a regression before it ships.
• Flue + Jetty: The complete flue-jetty walkthrough: grade every Flue agent run with an independent rubric and catch a regression before it ships.

Not what you're looking for? To wire Jetty into your own application directly — run, check, fix, rerun from code — check out the Jetty Client SDK →
