Discovery
64%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 description effectively communicates the core capability of extracting and summarizing content from various media sources, with good natural trigger terms including the helpful YouTube/video fallback note. However, it lacks an explicit 'Use when...' clause and could be more specific about the types of files supported and output formats available.
Suggestions
Add an explicit 'Use when...' clause, e.g., 'Use when the user wants to transcribe audio/video, summarize web content, or extract text from media files.'
Specify supported file types more clearly (e.g., '.mp3, .mp4, .wav, audio files, video files') to improve distinctiveness and reduce overlap with generic file processing skills.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names domain (URLs, podcasts, local files) and some actions (summarize, extract text/transcripts), but lacks comprehensive detail about specific capabilities like format handling or output options. | 2 / 3 |
Completeness | Clearly answers 'what' (summarize/extract from various sources), but lacks an explicit 'Use when...' clause. The parenthetical hint about YouTube/video is helpful but doesn't constitute proper trigger guidance. | 2 / 3 |
Trigger Term Quality | Good coverage of natural terms users would say: 'summarize', 'extract text', 'transcripts', 'URLs', 'podcasts', 'YouTube', 'video', 'transcribe'. The parenthetical note adds valuable trigger terms. | 3 / 3 |
Distinctiveness Conflict Risk | Somewhat specific to transcription/summarization of media content, but 'URLs' and 'local files' are broad enough to potentially overlap with general file processing or web scraping skills. | 2 / 3 |
Total | 9 / 12 Passed |
Implementation
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 strong, well-crafted skill that efficiently documents a CLI tool. It excels at conciseness and actionability with copy-paste ready examples. Minor improvement could be made to the YouTube transcript workflow guidance to clarify decision points.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely lean and efficient. No unnecessary explanations of what summarization is or how CLIs work. Every section delivers actionable information without padding. | 3 / 3 |
Actionability | Provides copy-paste ready commands with real examples. Flags are clearly listed with their options, and environment variable setup is explicit and complete. | 3 / 3 |
Workflow Clarity | For a simple CLI wrapper this is mostly clear, but the YouTube transcript handling could benefit from explicit validation steps. The guidance about 'huge transcripts' is vague about what constitutes 'huge' and when to summarize vs expand. | 2 / 3 |
Progressive Disclosure | Well-organized with clear sections. For a simple CLI skill under 50 lines, the structure is appropriate with quick start, specific use cases, and configuration separated logically. No external references needed. | 3 / 3 |
Total | 11 / 12 Passed |
Validation
72%Checks the skill against the spec for correct structure and formatting. All validation checks must pass before discovery and implementation can be scored.
