Discovery
50%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 is concise and clearly identifies a specific niche (Sonos speaker control) with concrete actions listed in parentheses. However, it critically lacks a 'Use when...' clause, which hurts completeness significantly. Adding trigger guidance and more natural user terms would substantially improve skill selection accuracy.
Suggestions
Add a 'Use when...' clause, e.g., 'Use when the user wants to control Sonos speakers, play music, adjust volume, or manage speaker groups.'
Include additional natural trigger terms users might say, such as 'music', 'pause', 'skip track', 'smart speaker', 'home audio', or 'speaker system'.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: discover, status, play, volume, and group. These are clear, actionable capabilities for controlling Sonos speakers. | 3 / 3 |
Completeness | Describes what it does (control Sonos speakers with specific actions) but completely lacks a 'Use when...' clause or any explicit trigger guidance, which per the rubric caps completeness at 2, and the 'when' is so absent it warrants a 1. | 1 / 3 |
Trigger Term Quality | Includes 'Sonos speakers' and action terms like 'play', 'volume', 'group' which users might say, but misses common variations like 'music', 'pause', 'skip', 'smart speaker', or 'home audio'. No file extensions or alternate phrasings. | 2 / 3 |
Distinctiveness Conflict Risk | 'Sonos speakers' is a very specific niche with distinct triggers. It's unlikely to conflict with other skills since Sonos is a specific product/brand. | 3 / 3 |
Total | 9 / 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 Sonos speakers via CLI. It's highly concise with concrete, executable commands organized in a logical progression from basic to advanced operations. The troubleshooting notes add practical value without bloat.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Every line earns its place. No unnecessary explanations of what Sonos is or how CLI tools work. Assumes Claude's competence and provides only the commands needed. | 3 / 3 |
Actionability | Provides concrete, copy-paste ready CLI commands for all common operations (discover, status, play, volume, grouping, favorites, queue, search). The fallback tip for SSDP failure is specific and actionable. | 3 / 3 |
Workflow Clarity | For a simple skill covering CLI commands, the workflow is clear: discover first, then control by name. The logical grouping of commands (quick start → common tasks → notes/troubleshooting) provides an unambiguous sequence. No destructive or batch operations require validation checkpoints. | 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 (quick start, common tasks, notes) that are easy to scan and navigate. | 3 / 3 |
Total | 12 / 12 Passed |
