jellyfin

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

In plain words
What is it for?
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.
Why use it?
It lets you inspect and control the server from the terminal without manually navigating its web interface.

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 yesterday.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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 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.
