About Introducing Langy

Langy is an automated AI engineer inside LangWatch: it reads your traces, writes Scenario tests and evaluations, opens PRs, and proves every fix in your CI. It is a full coding agent: it reads your production traces, writes Scenario tests and evaluations against what it finds, connects to your GitHub, opens a pull request on your actual codebase, and proves the change by running the simulations it wrote in your CI. You talk to it where your evaluation results already live, and what comes back is a diff with green checks attached.
