Bring Your Friends and Framework
You don't have to run your agent on Jetty to get value from it. Keep the agent wherever it already lives and use Jetty as the independent grader, store, and A/B harness around it: 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 a runbook the agent under test never sees, you can swap frameworks, models, or providers and keep the exact same measuring stick. The only Jetty-specific code is a few SDK calls.
Two worked examples, end to end, and the general shape:
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.
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 app directly, use the Client SDK.
