Field notes
Gmail labels only
Label changes are not customer email. Score should reflect that.
What Crash Labs saw
Gate WARN · risk 33/100 · 2 outbound action(s) · coverage 100%.
"Untitled workflow" can launch with caution (WARN): 3 high finding(s), risk 33/100. Start with: Nobody gets alerted when this workflow fails.
Why this breaks in production
high
Nobody gets alerted when this workflow fails
You may think an email or invoice finished when it actually stopped halfway - and no one is paged.
Fix → In n8n Settings, set an Error Workflow (or add an Error Trigger flow) that Slack/emails your team with the failed run link.
high
"Gmail - add label to message" can fail with no backup path
Customers get silence, duplicate retries, or a half-finished experience with no internal alert.
Fix → Turn on retry for transient SMTP/API errors, and route hard failures to an error branch that alerts someone.
