App errors

Go to Integrations, press Add on App errors and press Add again. You get its URL and token at once, and Send a test error opens an issue with an agent so you see it work. To wire your repo, press Start setup on its page: an agent finds every service that runs in production, sends its errors here, throws a test error and opens a pull request. Alerts from your tools work the same way: Better Stack, ClickStack, Cloudflare and Axiom. Add a tool again for another repo or team; each one is its own row. Agents run on the team account, or as whoever added it until that's set up. Anyone on the team can open, message and pause those agents.

Under Prompt for every agent this source starts, change what every agent should do besides fixing the error, like which docs to follow. Each new agent gets it before the error.

Here's what your app sends:

POST /api/v1/signals
Authorization: Bearer sig_…
Content-Type: application/json

{ "service": "api", "message": "Cannot read properties of undefined", "stack": "TypeError: …" }

The same error always lands on the same issue, even across releases. Only a brand-new error, or one you resolved that comes back, starts an agent. All the details are in the Errors API.
