client-sdk

A software kit for controlling Project Aria Gen 2 smart glasses from a computer. It includes command-line tools and a Python library for pairing devices, managing recordings, streaming sensor data, and configuring multiple devices.

In plain words
What is it for?
Pairing Aria Gen 2 glasses, starting and stopping recordings, receiving live sensor streams, visualising data, and managing multi-device setups.
Why use it?
It provides the connection and device-management pieces needed to work with the glasses from code rather than controlling every step manually.

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

client-sdk scanned grade B with 1 finding 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 2d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

Aria Client SDK

The Client SDK lets you control Aria Gen2 glasses from a host PC — pair devices, manage recordings, stream live sensor data, and configure multi-device setups. It ships as a pip package with both a CLI (aria_gen2) and a Python SDK (aria.sdk_gen2).

How to Use This Skill

This skill teaches the concepts and capabilities. For exact API details:

  • CLI: aria_gen2 <subcommand> --help
  • Python SDK: Read sdk_gen2.pyi in the installed package (site-packages/aria/), or run help(aria.sdk_gen2)
  • Sample scripts: python -m aria.extract_sdk_samples --output ~/Downloads/

Installation

Prerequisites

  • Aria Gen2 device with Companion App paired
  • USB cable connecting device to PC
  • One-time authentication: aria_gen2 auth pair (requires approval in Companion App)

Capabilities Overview

The SDK exposes five capability areas through both CLI and Python SDK:

Authentication

One-time device-PC pairing. The PC generates a client hash, the user approves in the Companion App, and subsequent connections are automatic. Use aria_doctor to verify system readiness before pairing.

Recording

Start/stop recordings on the device, list recordings, download as VRS files, delete. Recordings use configurable profiles that define which sensors are active and at what rate — predefined profiles (e.g. general-purpose, high-res RGB, streaming-optimized) are available on-device, plus custom profiles via JSON. Downloaded VRS files are processed with ProjectAriaTools (PAT).

Streaming

Stream live sensor data from the device to the host PC in real-time. Three streaming interfaces with different tradeoffs:

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.

client-sdk is a skill published in the GitHub repository facebookresearch/projectaria-plugins (8 stars, last pushed 7d ago), licensed Apache-2.0. It adds 89 tokens to every session and 2,870 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
