What is claude-cmux-skill marketplace?

A marketplace listing for a plugin that coordinates separate Claude Code sessions in cmux, a terminal environment with split panes and related controls.

Orchestrating sessions, monitoring agents, automating browser tasks, managing sidebar information, sending notifications, and using the cmux command line.

It provides one place to discover a tool for managing multiple coding-agent sessions and their status.

Security

Grade A, and why

claude-cmux-skill marketplace scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
