AI Agent Skill: Proc CLI for Process & Port Management

AI Agent Skill: Proc CLI for Process & Port Management

The Proc CLI skill assists AI agents in effectively managing processes and ports across multiple operating systems, including macOS, Linux, Windows, FreeBSD, and NetBSD. This tool is designed to safely find, inspect, and stop processes and ports that are occupied or in use, ensuring that necessary resources are freed without mistakenly affecting unrelated processes.

What this skill does

• Finds and inspects processes and ports to diagnose usage issues such as "address already in use".
• Releases occupied ports by safely stopping processes identified by port, PID, name, file, or directory.
• Enables controlled termination, pausing, or resuming of processes, with a preview step to prevent unintended actions.
• Supports development environments by cleaning up server processes and headless browsers started by agents.
• Functions as a comprehensive alternative to command-line utilities like lsof, ps, pgrep, pkill, killall, and netstat.

Who it is for

This skill is intended for developers and teams employing AI coding agents such as Claude Code, Cursor, and Codex. It is particularly useful for those managing complex development environments where process and port management are frequent requirements.

Use cases

• Resolving port conflicts during software development by identifying and clearing processes using specific ports.
• Managing and troubleshooting sluggish or unresponsive systems by inspecting and controlling active processes.
• Maintaining an efficient development environment by cleaning up orphaned processes and servers.

Technical details

The Proc CLI skill leverages built-in tools such as proc-cli and employs aiapplication frameworks compatible with AI agents like Claude Code, Cursor, and Codex. The tool operates under a strict safety protocol: actions are facilitated through a preview that requires user approval before execution, minimizing the risk of affecting unintended targets. This skill supports proc-cli version 2.0 or later.
