spotify-player skillA

spotify-player is agent-read markdown (skill) from letta-ai/skills: Terminal Spotify playback/search via spogo (preferred) or spotify_player..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add letta-ai/skills/spotify-player@git:20260422.d32735f
Exact content
mdr add letta-ai/skills/spotify-player@sha256:8e614d8dd786efa6

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
