emby-integrationEmby API, authentication flow, rating scale, streaming, scrobbling, and video playback.
Emby Integration is an agent skill from ad-repo/nullplayer. Emby API, authentication flow, rating scale, streaming, scrobbling, and video playback. Use when working on Emby integration, library browsing, playback reporting, or video casting.
Its SKILL.md is about 3.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs. The repository describes itself as: nullPlayer is a free open source macOS media player with some unique features.
Read from SKILL.md and the folder at commit bd7ddac. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Emby Integration loads about 3.2k tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 1,313 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,313 words (~3,241 tokens).
“NullPlayer supports Emby media servers for music streaming, video playback (movies and TV shows), browsing, and scrobbling.”
Just SKILL.md in skills/emby-integration of ad-repo/nullplayer.

Emby Integration fits situations like: working on Emby integration; library browsing; playback reporting.
Run `npx skills add ad-repo/nullplayer --skill emby-integration -a claude-code`. Or copy the skill folder (skills/emby-integration in ad-repo/nullplayer) into .claude/skills/emby-integration in your project. Claude Code loads it when a task matches its description.
Run `npx skills add ad-repo/nullplayer --skill emby-integration -a codex`. Or copy the skill folder (skills/emby-integration in ad-repo/nullplayer) into .agents/skills/emby-integration in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ad-repo/nullplayer --skill emby-integration -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/emby-integration, .gemini/skills/emby-integration, .github/skills/emby-integration and .opencode/skills/emby-integration in your project.
SKILL.md names no scripts, command-line tools or credentials: Emby Integration is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Emby Integration has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
About 3.2k tokens (SKILL.md is roughly 13k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Emby Integration: Configuring Horizon (coollabsio/coolify, 63k stars), Nestjs Best Practices (rolling-scopes/rsschool-app, 10k stars), Sub2API Admin (Wei-Shaw/sub2api, 44k stars) and Firecrawl Build Onboarding (firecrawl/firecrawl, 190k stars).
