A command-line interface for managing a Jellyfin media server, a self-hosted service for storing and streaming films, shows, music, and other media.

Use it to search or browse the media library, start a library scan, inspect active playback, control playback remotely, list users, or check server status.

It lets you inspect and control the server from the terminal without manually navigating its web interface.

Getting it into your agent

Security

Grade A, and why

jellyfin scanned grade A with 1 finding 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.

Use this skill whenever the user wants to browse or search their Jellyfin library, trigger a library scan/refresh, inspect active playback sessions or remote-control playback, list users, or check server/system status. Trigger on phrases like \"scan my Jellyfin library\", \"what's playing on Jellyfin\", \"search Jellyfin for X\", \"refresh Jellyfin\", \"list Jellyfin users\", \"Jellyfin server info\", or any mention of Jellyfin."

What it installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 125 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
