Description
Devin submitted a docs PR to PrefectHQ/prefect (21K+ stars) explaining a Kubernetes worker behavior. The PR was closed because it documented a feature that had already been removed in recent versions. Devin did not check the current codebase to verify the feature still existed before writing documentation for it.
Instruction Given
Explain Kubernetes worker cluster UID and kube-system access
Expected Behavior
Verify the feature exists in current code before documenting it
Actual Behavior
Wrote documentation for a behavior that was removed in recent versions. PR closed as the documented feature no longer existed in the codebase.
Impact / Damage
Wasted maintainer review time on a well-known open source project (21K stars). Could have confused users if merged.
