This tool modifies DNS configuration, which is a critical network service. While reversible (Write category rather than Destructive), misuse could redirect all DNS traffic or cause widespread network disruption. The lack of description reduces confidence slightly, but the semantic meaning of 'system_dns_update' is clear.

From the tool's own definition: "Tool name 'system_dns_update' indicates modification of DNS system configuration. The 'update' verb combined with 'system_dns' scope suggests reversible changes to DNS settings, a core network infrastructure component."
