What it does
Music is an agent skill from autonomous-ai/Physical-AI-Operating-System. Play and stop music from YouTube through the device's speaker on user request.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `skill.json`).
It works with YouTube. The repository describes itself as: The open-source operating system for physical AI. The licence is Apache-2.0.

Read from SKILL.md and the folder at commit d5efe9d. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
Shell commands in SKILL.md call:
curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Music loads about 1.3k tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 606 words of instructions outside code blocks.
Always· name and description, kept in context so the agent knows when to use it

~1.3k
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.
Safety
Auto-check passed
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.

description
Play and stop music from YouTube through the device's speaker on user request.
Music
Play music through the device's speaker by searching YouTube. Use this when the user asks to play, sing, or listen to music.
Spoken output: Everything outside HW markers in your reply is read aloud. For a play/stop request, start with the HW markers, then give one short confirmation and end the reply. Keep song-selection reasoning, transcript interpretation, and speaker attribution in the provider's native thinking channel (omit analysis if unavailable), without a text summary before/after tools or in the final answer; do not add a preamble, a draft confirmation, or a second confirmation.
Workflow
Specific song / artist → play directly. When [voice-instruction] is present, use that request; a conflicting noisy [transcript] does not replace the song title. No habit or identity lookup is needed. Use a known speaker for person; otherwise omit the field silently.
If music_patterns exists and current hour is within peak_hour ± 1 → use preferred_genre to pick a song, no need to ask.
Otherwise → ask: "What are you in the mood for?". The file is bootstrapped lazily by wellbeing on its first threshold nudge; do not invoke habit Flow A from here.
Reply format:
[HW:/audio/play:{"query":"Bohemian Rhapsody Queen","person":"{name}"}][HW:/emotion:{"emotion":"excited","intensity":0.8}] Playing Bohemian Rhapsody!
{name} is the speaker identified in the injected context. If nobody is identified, drop the field entirely — [HW:/audio/play:{"query":"Bohemian Rhapsody Queen"}]. Never invent a name or reuse one from an example.
Stop: [HW:/audio/stop:{}] Music stopped.

The identified speaker's label, lowercase ({name} from the injected context) — omit the field when nobody is identified. Unmatched names are logged under the shared unknown bucket, so a made-up name buys nothing.
Do NOT use track, artist, title, song — those return 422.

How HW markers work
The Go server intercepts [HW:/audio/play:...] / [HW:/audio/stop:...]in your reply text and forwards to HAL. This is the ONLY way to play music — never use exec, mpv, vlc, yt-dlp, or curl /audio/play.
The marker is passive text, NOT a command to run. Write it directly in your reply and stop — the OS runs it for you. Do NOT try to "execute" or "invoke" it.
❌ WRONG — echoing/wrapping the marker in a shell tool. echo only prints to stdout inside your sandbox; the OS never sees it, so no music plays:bash
echo '[HW:/audio/play:{"query":"Gymnopedie No 1 Satie"}]'
✅ RIGHT — the marker IS your reply text (no tool call at all):
[HW:/audio/play:{"query":"Gymnopedie No 1 Satie"}][HW:/emotion:{"emotion":"curious","intensity":0.6}] Here's some Satie. 🎹
Never put [HW:...] inside echo, exec, bash, printf, or any tool argument. If you find yourself reaching for a tool to play music, stop — just emit the marker as text.
Error handling
503 → "Music playback is not available right now."
409 → music already playing; stop first, then play new song.
No results → tell user and suggest a different query.
Rules
Emotion marker is mandatory after every /audio/play.
person MUST be lowercase.
Don't recite lyrics or "sing" via TTS — call /audio/play and let real music play.
Volume control belongs to the Audio skill, not this one.
If user specifies genre or mood ("play something relaxing"), pick a well-known song — no need to ask further.

How do I install Music in Claude Code?
Run `npx skills add autonomous-ai/Physical-AI-Operating-System --skill music -a claude-code`. Or copy the skill folder (skills/music in autonomous-ai/Physical-AI-Operating-System) into .claude/skills/music in your project. Claude Code loads it when a task matches its description.
How do I install Music in Codex?
Run `npx skills add autonomous-ai/Physical-AI-Operating-System --skill music -a codex`. Or copy the skill folder (skills/music in autonomous-ai/Physical-AI-Operating-System) into .agents/skills/music in your project. Codex loads it when a task matches its description.
Can I use Music in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add autonomous-ai/Physical-AI-Operating-System --skill music -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/music, .gemini/skills/music, .github/skills/music and .opencode/skills/music in your project.
What does Music need to run?
Going by SKILL.md and its folder, Music needs the command-line tools its instructions call (curl).
Does Music access the network?
SKILL.md contains no URLs. Its commands use curl, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is Music safe to install?
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.
What licence does Music use?

How many tokens does Music use?
About 1.3k tokens (SKILL.md is roughly 5.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Music?
Skills that share tags, products or a category with Music: Markitdown (ImCa0/just-laws, 781 stars), Banner Design System (nextlevelbuilder/ui-ux-pro-max-skill, 134k stars), Agent Reach (Panniantong/Agent-Reach, 95k stars) and Last30days (mvanhorn/last30days-skill, 64k stars).
