Use this guide when a preview, test, deployment, or runtime path fails.

Give Agent the failure

Include the error, failing command, URL, or deployment state.
The preview route /settings returns a server error.
Find the cause, fix it, and run the relevant check.

Ask for cause before edits

For unclear failures, ask Agent to explain the cause before changing files.
Inspect the logs and related code first.
Tell me the likely cause before editing.

Keep the fix scoped

Name the behavior that must stay unchanged.
Fix the failing settings route.
Do not change the account routes.
Keep the existing form components.

Verify the fix

Ask Agent to rerun the failing path and any related checks.
After the fix, rerun the failing test or preview path.
Report the command output and any remaining risk.
