music SKILL.md skillA
This file is byte-identical to the first copy the registry indexed, one of 3 indexed copies. Same content hash, so the same checks give both the same grade.
music from autonomous-ai/physical-ai-operating-system is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add autonomous-ai/physical-ai-operating-system/music@git:20260917.e53c7cfPins git:20260917.e53c7cf in mdr.lock. Pin the fingerprint instead.

Play and stop music from YouTube through the device's speaker on user request.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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
1. **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.
2. **Vague request** (*"play music"*, *"sing something"*) → check habit patterns first:
```bash
cat /root/local/users/{name}/habit/patterns.json 2>/dev/null
```

How to install
mdr add autonomous-ai/physical-ai-operating-system/music@sha256:5c46828ecd2150deThe line at the top of this page pins the label git:20260917.e53c7cf, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
