{"agent":"claude","input":"Add OpenTelemetry tracing to this Express service: HTTP server spans named by route, database spans for every Prisma query as children of the request span, and outbound HTTP client spans. Load the SDK before Express starts, and configure it only through the standard OTEL_* environment variables. Run a local OpenTelemetry Collector with a file exporter in the sandbox, start Postgres and the service, exercise the main endpoints, and check that each request's trace contains its database spans. Run the existing tests. Open a pull request with the changes, a short excerpt of the exported traces, and the environment variables a deployment must set.","resources":[{"url":"https://github.com/your-org/your-service"}]}
