Security audit

Poyo Hunyuan 3d 3 1

Security checks across malware telemetry and agentic risk

Overview

The available evidence shows a simple API-oriented skill with disclosed curl and API-key use, with no evidence of hidden, destructive, or unrelated behavior.

Before installing, confirm the skill’s documentation clearly says it will make outbound API calls with POYO_API_KEY, use a least-privileged key if available, and avoid pasting secrets into chats or logs.

Finding
The skill declares shell capability requirements via `curl` in metadata and execution guidance, but the static finding indicates those capabilities are not reflected in an explicit permissions declaration. That mismatch can weaken review and policy enforcement because users or platforms may not realize the skill can initiate networked shell actions that handle secrets like `POYO_API_KEY`.
