Ctop

Category: General · Sub-category: general-misc · Last updated: 2026-05-24

Inspect, monitor, and control running AI coding agent sessions across terminals via the `ctop` CLI. Use when the user asks "what agents are running", "what sessions do I have", "what is my master agent doing", "is my context about to compact", "how much have I spent", "kill the stuck session", "clean up ghost sessions", "what's idle", or anything that requires visibility across Claude Code / Codex / OpenCode sessions. Works on macOS, Linux, Windows. No network calls — reads local process state and session files.

From the source SKILL.md

ctop is htop for AI coding agents. It already exposes every running Claude Code / Codex / OpenCode session as structured data: PID, model, cost, context-free %, branch, cwd, status. This skill teaches you how to query it from inside another agent session.

What this skill does

Ctop is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/ctop/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user asks "what agents are running", "what sessions do I have", "what is my master agent doing", "is my context about to compact", "how much have I spent", "kill the stuck session", "clean up ghost sessions", "what's idle", or anything that requires visibility across Claude Code / Codex / OpenCode sessions. Works on macOS, Linux, Windows.
