audio SKILL.md skillB
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.
audio 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/audio@git:20260910.44ed5b7Pins git:20260910.44ed5b7 in mdr.lock. Pin the fingerprint instead.

Low-level speaker and microphone hardware control — adjust volume, play test tones, record raw audio. Do NOT use for TTS/speech (that is the Voice skill).
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
# Audio Control
## Quick Start
Control the device's speaker and microphone hardware directly. Use this for volume adjustments, test tones, and raw audio recording. This is LOW-LEVEL hardware control only.
## Workflow
1. Determine the user's audio hardware need:
- Volume adjustment -> use `POST /audio/volume`
- Check current volume -> use `GET /audio/volume`
- Diagnostics / test -> use `POST /audio/play-tone`
- Raw recording -> use `POST /audio/record`
2. For explicit volume/tone/recording requests, call the requested endpoint directly and handle its response. Use `GET /audio` for device diagnostics, not routine preflight. Relative volume changes still need `GET /audio/volume`.
3. Execute the appropriate API call
4. Confirm the action to the user
## Examples
Input: "Louder please" / "Turn it up"
Output: Check current volume with `GET /audio/volume`, then increase by ~15 with `POST /audio/volume`. Confirm: "Volume set to 85%."
Input: "Set volume to 50%"
Output: Call `POST /audio/volume` with `{"volume": 50}`. Confirm: "Volume set to 50%."
Input: "Mute" / "Too loud"
Output: Call `POST /audio/volume` with `{"volume": 0}`. Confirm: "Muted."
Input: "I can't hear you"

How to install
mdr add autonomous-ai/physical-ai-operating-system/audio@sha256:815d7e7d964238bbThe line at the top of this page pins the label git:20260910.44ed5b7, 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.
