Detect and send production issues straight to your agent

As agents help us build more complex applications, both humans and agents need a better way to stay on top of what goes wrong in production. Coding agents can already query observability data, navigate a repository, change code, write tests, and open a pull request. What remains manual is connecting those steps: recognizing that repeated failures come from the same bug, gathering the relevant logs and traces, sending that context to an agent, and checking whether the fix worked. Without that structured handoff, the agent must search raw telemetry to reconstruct the scope and context of the failure before it can investigate.

Today, we are introducing Issues, built-in error monitoring for Cloudflare Workers (now in open beta!) to streamline this workflow. Issues can:

Fix your first issue with the following prompt for your agent with CF CLI or checkout the documentation to get started:

With one line of configuration, you can start receiving Issues detected on your Worker with no additional instrumentation required. Issues are built into the Workers runtime, so there is no SDK to install or application wrapper to add. 

Once enabled, Issues records uncaught exceptions, failed invocations, HTTP 5xx responses, output from console.log() and console.error(), and logs that contain a stack trace. It also flags runaway alarm conditions and code that writes large volumes of logs inside loops.

Consider a Worker whose handler starts throwing errors after a deployment. Every failed request has a different request ID, but they all come from the same bug. Issues groups them together and shows when the error first appeared, how many times it has happened, and whether it is becoming more frequent.
