Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is an excellent skill description that hits all the marks. It provides specific concrete actions, includes natural trigger terms users would say, has an explicit 'Use when' clause, and is clearly scoped to Spotify on macOS, making it highly distinctive.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: play/pause, skip tracks, control volume, play artists/albums/playlists. Also specifies the platform (macOS) and the application (Spotify). | 3 / 3 |
Completeness | Clearly answers both 'what' (control Spotify playback on macOS with specific actions) and 'when' (explicit 'Use when' clause with multiple trigger scenarios). | 3 / 3 |
Trigger Term Quality | Includes natural keywords users would say: 'play music', 'control Spotify', 'change songs', 'adjust Spotify volume', plus specific actions like 'play/pause', 'skip tracks', 'artists/albums/playlists'. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive — targets a specific application (Spotify), a specific platform (macOS), and a specific domain (music playback control). Unlikely to conflict with other skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is an excellent, lean skill that provides exactly what Claude needs to control Spotify on macOS. It's concise, fully actionable with copy-paste-ready commands, and well-structured with clear sections. The 'Play by Name' workflow cleverly works around the lack of a search API by using web search to find Spotify URIs.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Every line earns its place. No unnecessary explanations of what Spotify is, how AppleScript works, or what macOS is. The command table is compact and scannable. | 3 / 3 |
Actionability | Provides fully executable bash commands and AppleScript one-liners that are copy-paste ready. The 'Play by Name' section gives a concrete workflow with real Spotify IDs as examples. | 3 / 3 |
Workflow Clarity | The 'Play by Name' section has a clear 3-step sequence (search → extract ID → play). For a non-destructive, simple playback control skill, no validation checkpoints are needed. The single-task commands are unambiguous. | 3 / 3 |
Progressive Disclosure | For a simple, under-50-line skill with no need for external references, the content is well-organized into logical sections (Commands, Play by Name, Notes) with clear headers and appropriate brevity. | 3 / 3 |
Total | 12 / 12 Passed |
