Media Player

**Quick judgment**: A simple, thin wrapper around `mpv` for local media playback. It’s well-suited for agents that need to start/stop audio or video on a host machine, assuming `mpv` is installed and the environment is interactive (e.g., a user’s desktop). Functionality is intentionally minimal (play/pause/stop), but that keeps it easy to reason about. **Main strengths** - Uses `mpv`, which is fast, stable, and supports many formats and streams. - Supports both local files and remote URLs, covering many basic playback scenarios. - Very small API surface, which reduces integration complexity and potential bugs. **Key risks / limitations** - **Dependency on `mpv`**: Requires `mpv` to be installed and accessible; instructions shown are distro-specific (`dnf`), so other platforms may need manual setup. - **Network/URL usage**: Playing arbitrary remote URLs means an agent can cause the host to make outbound network requests to arbitrary endpoints (potential SSRF-style access to internal resources if the host has such access). This is a moderate but real network/privacy consideration in sensitive environments. - **User experience risks**: An untrusted agent could start loud or unwanted media playback, which is more of a UX/annoyance issue than a security problem, but still relevant. - **No advanced controls**: Lacks volume control, seeking, playlist management, or status querying, so it may not suffice for more sophisticated media workflows. **Recommended scenarios** - Desktop or workstation environments where `mpv` is already installed or can be easily installed, and interactive playback is desired. - Agents that need a basic, reliable way to play or stop local or streamed audio/video, without complex control requirements. - Non-sensitive environments where outbound media streaming to arbitrary URLs is acceptable and there are no strict network isolation constraints. **Less suitable for** - Highly locked-down or security-sensitive systems where arbitrary outbound network requests from media players are not acceptable. - Headless or audio-less servers where media playback has no effect or where no sound/display pipeline exists. - Workflows requiring fine-grained playback control (seeking, volume, track info, playlists, etc.), which this skill does not expose.
