servo-tracking 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.
servo-tracking 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.

Use ONLY to follow/track/watch a movable physical OBJECT vision can recognize (cup, bottle, phone, hand, person, pen, book, remote, toy, keys, pet, a specific face). NEVER use for furniture or fixed locations (desk, table, wall, floor, ceiling, door, window, workspace, room) — those are directions; use servo-control /servo/aim. NEVER use for direction words (left, right, up, down, center). If the user combines a direction AND an object ("look at the desk and follow the cup…
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
# Vision Tracking
## Quick Start
Tracks and follows any object by name. YOLOWorld detects the object in the camera frame, TrackerVit follows it in real-time with servo movement.
## Workflow
1. User names an object to track.
2. **If the user also hints at a direction** ("look at desk and follow cup", "point at the table and watch the phone"), fire `/servo/aim` FIRST so the camera is pointing at the right region before YOLO detection runs. Then fire `/servo/track`. The aim should complete in ~2s before the track call takes over.
3. Prefix reply with `[HW:/servo/track:{"target":["<label1>","<label2>"]}]` — the device detects and follows.
- `target` accepts a list of candidate labels. Pass 2-4 synonyms/variants to maximise the chance YOLOWorld finds the object on the first try.
- A single string also works (`{"target":"cup"}`) for backward compatibility, but the list form is preferred when the object could reasonably have multiple names.
4. To stop, prefix with `[HW:/servo/track/stop:{}]`.
## Examples

How to install
mdr add autonomous-ai/physical-ai-operating-system/servo-tracking@sha256:878e57e49278a83aThe 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.
