The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill instructs the agent to use npx to download and execute the metavr tool from the NPM registry. Since metavr is a tool associated with the vendor meta-quest and NPM is a trusted package registry, this follows standard development practices for performance analysis.
[COMMAND_EXECUTION]: The skill utilizes shell commands (metavr, npx) to capture, list, load, and query Perfetto traces from Meta Quest devices. These commands are restricted to the allowed-tools configuration and are used exclusively for legitimate VR performance debugging.
[SAFE]: File system access is limited to searching for and loading performance trace files (.pftrace) within standard user directories such as ~/Documents, ~/Downloads, and the current working directory.
[SAFE]: The skill's instructions focus on analyzing frame timing, CPU/GPU bottlenecks, and thread states using standard Perfetto SQL queries, with no evidence of prompt injection, data exfiltration, or malicious persistence.
