Debug Rocket Route

Use this skill to debug an API route in apps/server without drifting into unrelated parts of the repository.

When to use

• an endpoint returns the wrong status or payload
• a route is mounted but not reachable
• State<Arc<ServiceLayer>> wiring is wrong
• Db usage or blocking async boundaries fail
• Swagger or OpenAPI registration is missing

Procedure

1. Locate the handler in apps/server/src/routes/.
2. Confirm it is exported in routes/mod.rs and mounted in apps/server/src/main.rs.
3. Verify request DTOs, response DTOs, and error mapping.
4. Check service injection through rocket::State<Arc<ServiceLayer>>.
5. Check database execution boundaries such as db.run, blocking behavior, and any async bridging.
6. Step one hop into the owning domain service if the route only forwards the work.
7. Apply the smallest patch that explains or fixes the failure.
8. Validate with the narrowest executable check available for that route or handler path.

Soundome-specific checks

• Prefer thin handlers that defer to domain::services.
• Avoid leaking Diesel types into the HTTP layer.
• Keep HTTP error messages safe and free of secrets.
• Update OpenAPI annotations when request or response shapes change.
