Protects development environments by enforcing a verification protocol before terminating processes on busy ports.
The Port Safety skill provides a critical operational guardrail for Claude Code, designed to prevent the accidental termination of important system or user processes. By implementing a standardized protocol—identifying the process via lsof, checking its origin, and requesting explicit permission for foreign tasks—it ensures that Claude manages local network resources responsibly without disrupting your background workflows or system services.
