Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00089 | $0.02870 |
| Opus 5 | $0.00044 | $0.01435 |
| Sonnet 5 | $0.00018 | $0.00574 |
| Haiku 4.5 | $0.00009 | $0.00287 |
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.pyiin the installed package (site-packages/aria/), or runhelp(aria.sdk_gen2) - Sample scripts:
python -m aria.extract_sdk_samples --output ~/Downloads/
Installation
- Install:
pip install projectaria-client-sdk(in a virtual environment, Python 3.10–3.12) - Verify:
aria_doctor— configures system ports and verifies connectivity - Supported: Linux x64 (Ubuntu/Fedora), macOS Apple Silicon
- Docs: https://facebookresearch.github.io/projectaria_tools/gen2/ark/client-sdk/start
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.
