[bug] Ignored error from StopToolSets in loadTeam cleanup function

[docker-agent]

🟡 medium - bug

File: cmd/root/debug.go (line 83)

Code

cleanup := func() {
	if err := t.StopToolSets(ctx); err != nil {
		slog.Error("Failed to stop tool sets", "error", err)
	}
}

Problem

The cleanup function, returned by loadTeam, calls t.StopToolSets(ctx) and logs any error but does not return it. This means that if StopToolSets fails, the error is suppressed, and the caller of cleanup (which is typically a defer statement) will not be aware of the failure. This can lead to a false sense of success in resource cleanup.

Suggested Fix

The cleanup function should return the error from t.StopToolSets(ctx). Since it is typically called via defer, the error will be silently ignored anyway, but at least the intention of handling the error would be clear. For better error handling, consider either changing cleanup to return an error that can be handled by the deferred caller, or handle the error more explicitly outside of defer. For now, simply removing _ = and adding a return err would make the intention clearer.
