Poyo Upload And Extend Audio

Security checks across malware telemetry and agentic risk

Overview

This skill is a straightforward PoYo audio-extension helper that discloses its API key and network use and limits live submissions to user-confirmed PoYo requests.

Install only if you intend to send audio-extension jobs to PoYo. Keep POYO_API_KEY in a server-side secret store, review payloads before submission, and avoid sending private audio URLs, callback URLs, lyrics, or customer data unless your policy allows sharing them with PoYo.

Finding
The skill declares shell-capable execution through its documented use of curl and a submission script, but there is no explicit permission declaration or guardrail metadata indicating that shell/network execution is constrained. This can lead to agents invoking external commands in environments where such capabilities were not transparently disclosed or policy-gated, increasing the risk of unintended command execution and data transfer.
