Please see this and advise

Your workspace has consumed $4.19 in Railway Agent tokens (canvas chat, deployment diagnosis, code-change suggestions) this billing cycle. This draws from the same $5 included credit as your compute usage, so with $0.03 in compute you're at $4.22 total and still within the $5 Hobby plan minimum. To prevent any future Agent charges, you can set the Agent hard limit to $0 at railway.com/workspace/usage by clicking "Update limits", which disables Agent features entirely while keeping everything else running.

You can set up usage alerts, limits, and view your usage breakdown - including per service costs - by heading to railway.com/workspace/usage.
