servo-control

servo-control is a skill for Claude Code, Codex from autonomous-ai/autonomous-os. It costs 0 tokens per session (2,328 once invoked), scanned B, original, Apache-2.0.

A device-control guide for aiming servo motors and playing named physical movements. Servo motors are small motors that change the device's direction or position.

In plain words
What is it for?
Use it to aim at supported directions such as a desk, wall, left, right, up, down, center, or the user. Use it also for named movements such as nodding or shaking.
Why use it?
It turns ordinary requests such as “look at me” or “point left” into the device actions and response markers that control the hardware. It also distinguishes aiming from playing an animation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

servo-control scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

curl -sX POST http://127.0.0.1:5001/servo/aim -H 'Content-Type: application/json' -d '{"direction":"right"}'

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

**Output:** move FIRST with curl (so the camera sees the NEW view), then snapshot, then reply:

How it starts

The opening of the file, as written. The whole thing — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Servo Control

Quick Start

Controls the device's servo motors for directional aiming and physical animations. Use /servo/aim for directional pointing, /servo/play for expressive animations.

Workflow

  1. Determine if the user wants to aim the light or play an animation.
  2. Prefix reply with the appropriate [HW:...] marker — the device fires it before TTS.
  3. Confirm the action to the user.

Important: For conversation reactions, use the Emotion skill instead — it combines servo + LED + eyes automatically.

Examples

Input: "Point the light at my desk" Output: [HW:/servo/aim:{"direction":"desk"}] Done, aimed the light at your desk.

Input: "Look at the desk" / "Look at my table" / "Look at my workspace" Output: [HW:/servo/aim:{"direction":"desk"}] Looking at the desk now.

Input: "Look at the wall" Output: [HW:/servo/aim:{"direction":"wall"}] Looking at the wall.

Input: "Look at me" Output: [HW:/servo/aim:{"direction":"user"}] Looking at you!

Input: "Look to the left" Output: [HW:/servo/aim:{"direction":"left"}] Looking left now.

Input: "Aim at the wall slowly" Output: [HW:/servo/aim:{"direction":"wall","duration":3.0}] Aiming at the wall slowly.

Input: "Nod for me" Output: [HW:/servo/play:{"recording":"nod"}] Nodding!

Input: "Turn left 15 degrees" Output: [HW:/servo/nudge:{"yaw":-15}] Turned a bit to the left.

Input: "Tilt up a little" Output: [HW:/servo/nudge:{"pitch":10}] Tilted up slightly.

Input: "Release the motors" Output: [HW:/servo/release:{}] Servos released — you can move the device by hand now.

Input: "Stop moving" / "Hold still" / "Freeze" / "Stand still" Output: [HW:/servo/hold:{}] OK, holding still.

Input: "Turn to the right and hold that position" Output: [HW:/servo/aim:{"direction":"right"}][HW:/servo/hold:{}] Turned right and holding. → Compound movement: emit one marker per clause, in order. They fire sequentially before TTS. Dropping the hold half means the device drifts back — never confirm a step you did not fire.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

servo-control is a skill published in the GitHub repository autonomous-ai/autonomous-os (277 stars, last pushed 2d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 2,328 tokens. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
