emotion 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.
emotion 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/emotion@git:20260916.bf68e22Pins git:20260916.bf68e22 in mdr.lock. Pin the fingerprint instead.

Express emotion through coordinated servo + LED + display eyes on EVERY conversational response. This is the PRIMARY response skill that makes the device feel alive. Do NOT use for ambiance lighting (use Scene) or custom LED colors (use LED Control).
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
# Emotion Expression
## Quick Start
Express emotion through the device's servo motors, LED colors, and display eyes simultaneously via a single API call. Call this with EVERY conversational response to make the device feel alive.
## Workflow
1. Determine which emotion best matches your conversational tone
2. Choose an intensity level (0.0 subtle to 1.0 full expression)
3. Prefix your reply with `[HW:/emotion:{"emotion":"name","intensity":0.9}]` — the device fires it async before TTS
4. Write your reply immediately after the marker
## How to Express Emotion
**No exec/curl needed.** Place inline markers at the start of your reply:
```
[HW:/emotion:{"emotion":"curious","intensity":0.8}] That's a great question!
```
For sequences (shock then happy):
```
[HW:/emotion:{"emotion":"shock","intensity":0.9}][HW:/emotion:{"emotion":"happy","intensity":0.8}] Wow, amazing!
```
Parameters:
- `emotion` (required): emotion name from the table below
- `intensity` (required): 0.0 (subtle) to 1.0 (full expression)
## Examples
Input: User asks an interesting question
Output: `[HW:/emotion:{"emotion":"curious","intensity":0.8}]` Then reply to the question.
Input: User shares good news

How to install
mdr add autonomous-ai/physical-ai-operating-system/emotion@sha256:c10e8ec443d4ca72The line at the top of this page pins the label git:20260916.bf68e22, 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.
