What is vrs-health-check?

A quality checker for recordings made with Meta Aria glasses. It looks for dropped frames, inconsistent sensors, invalid calibration, and timing problems before the recording is processed.

Use it to run recording checks from the command line or Python, choose a preset configuration, and adjust the pass/fail thresholds.

It helps catch recording problems early, so faulty data is not submitted for processing without a diagnosis.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00075	$0.00898
Opus 5	$0.00037	$0.00449
Sonnet 5	$0.00015	$0.00180
Haiku 4.5	$0.00007	$0.00090

Security

Grade A, and why

vrs-health-check scanned grade A with 0 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 12d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

VRS Health Check

VRS Health Check validates Aria recording quality — checking for dropped frames, sensor consistency, calibration validity, and timing issues. It runs automatically as part of MPS processing, but can also be run standalone to diagnose recording problems before submission.

How to Use This Skill

This skill teaches concepts. For details:

CLI: run_vrs_health_check --help
Configurations and checks: https://facebookresearch.github.io/projectaria_tools/gen2/ark/vrs_health_check/configuration_and_thresholds
Threshold customization: https://facebookresearch.github.io/projectaria_tools/gen2/ark/vrs_health_check/customization
Python API: from projectaria_vrs_health_check import vrs_health_check, then help(vrs_health_check)

Installation

Install: pip install projectaria-vrs-health-check (also installed automatically with projectaria-mps)
CLI command: run_vrs_health_check
Docs: https://facebookresearch.github.io/projectaria_tools/gen2/ark/vrs_health_check/installation

Capabilities Overview

Configurations

Multiple preset configurations exist for different device generations and use cases (e.g. general-purpose vs SLAM-focused with stricter thresholds). Run --list-configurations to see all available presets, and --show-configuration-json <name> to inspect all checks and thresholds for a configuration.

Key concept: All available configurations are evaluated during every run regardless of which one you select with --choose-configuration. The selected configuration controls the exit code and console output, but the JSON output contains results for all configurations.

Check Types

Two types of checks:

Numeric checks: Compare measured values (frame rates, drop ratios, timing deviations) against warn_threshold and fail_threshold values. Supports duration-dependent thresholds that relax for short recordings.
Boolean checks: Verify true/false conditions (calibration validity, file integrity).

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.
