Quality

Content

87%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This is a well-crafted, concise skill that provides specific CLI commands for two Spotify terminal tools with clear preference ordering. Its main strength is token efficiency and actionability—every line serves a purpose. The only minor weakness is the lack of a verification step after auth setup and no explicit guidance on detecting which tool is available.

Suggestions

Add a brief verification step after auth setup, e.g., 'Verify with `spogo status` — should show current playback or "No active device"'

Add a detection step at the top: 'Check availability: `which spogo || which spotify_player`' to make the fallback logic actionable

DimensionReasoningScore

Conciseness

Very lean and efficient. No unnecessary explanations of what Spotify is or how CLI tools work. Every line provides actionable information Claude wouldn't inherently know (specific command syntax, config paths, setup steps).

3 / 3

Actionability

Provides specific, copy-paste ready CLI commands for all common operations (search, playback, device management, auth setup). The commands are concrete and executable, not pseudocode or vague descriptions.

3 / 3

Workflow Clarity

For a simple skill this is mostly clear, but the setup workflow could benefit from a validation step (e.g., how to verify auth succeeded, or what to do if spogo isn't installed). The preference hierarchy (spogo preferred, spotify_player fallback) is stated but there's no explicit check for which is available.

2 / 3

Progressive Disclosure

For a simple, single-purpose skill under 50 lines with no need for external references, the content is well-organized into logical sections (setup, commands for each tool, notes). No bundle files are needed for this scope.

Description

40%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description identifies a clear niche (terminal-based Spotify control) with specific tool names, giving it good distinctiveness. However, it is too terse—it lacks concrete action details, natural user trigger terms like 'music' or 'play a song', and has no 'Use when...' clause, significantly limiting Claude's ability to know when to select this skill.

Suggestions

Add a 'Use when...' clause, e.g., 'Use when the user asks to play music, control Spotify playback, search for songs/artists/playlists, or manage a Spotify queue from the terminal.'

Include natural trigger terms users would say, such as 'music', 'play', 'song', 'artist', 'playlist', 'pause', 'skip', 'queue', 'now playing'.

List more specific concrete actions, e.g., 'Play, pause, skip, and queue tracks; search for songs, artists, albums, and playlists; control volume and playback state.'

DimensionReasoningScore

Specificity

Names the domain (Spotify) and two broad actions (playback, search) along with specific tools (spogo, spotify_player), but doesn't list concrete actions like 'play tracks', 'pause music', 'search artists', 'queue songs', etc.

2 / 3

Completeness

Provides a brief 'what' (Spotify playback/search via terminal tools) but completely lacks a 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill.

1 / 3

Trigger Term Quality

Includes relevant keywords like 'Spotify', 'playback', 'search', and tool names, but misses common user terms like 'music', 'play', 'song', 'artist', 'playlist', 'pause', 'skip', 'queue'.

2 / 3

Distinctiveness Conflict Risk

The mention of specific tools (spogo, spotify_player) and the terminal-based Spotify niche makes this highly distinctive and unlikely to conflict with other skills.
