youtube-tools
Fetch transcripts and create structured watching guides / summaries for YouTube videos. Use when the user asks to (1) get, fetch, extract, or download a transcript or captions from a YouTube video URL, or (2) summarize, create a watching guide, or produce a structured summary of a YouTube video. Trigger on youtube.com/watch, youtu.be, or youtube.com/shorts links.

Quality
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 clearly defines concrete capabilities (transcript fetching, structured summaries), provides comprehensive trigger terms covering natural user language variations, and explicitly states both what the skill does and when to use it. The inclusion of specific URL patterns (youtube.com/watch, youtu.be, youtube.com/shorts) makes it highly distinctive and unlikely to conflict with other skills.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Fetch transcripts', 'create structured watching guides', 'summaries for YouTube videos'. Also specifies sub-actions like 'get, fetch, extract, or download a transcript or captions'. | 3 / 3 |
Completeness | Clearly answers both 'what' (fetch transcripts, create structured watching guides/summaries) and 'when' (explicit 'Use when...' clause with numbered trigger scenarios and specific URL pattern triggers). | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: 'transcript', 'captions', 'summarize', 'watching guide', 'YouTube video URL', and specific URL patterns like 'youtube.com/watch', 'youtu.be', 'youtube.com/shorts'. These are highly natural keywords a user would use. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive — scoped specifically to YouTube videos with explicit URL patterns. Unlikely to conflict with general summarization or document extraction skills due to the YouTube-specific triggers and domain. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
92%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 skill that provides clear, actionable instructions for fetching YouTube transcripts and creating structured watching guides. The CLI commands are concrete, the output format template is detailed and copy-paste ready, and the workflow is logically sequenced. The content respects Claude's intelligence throughout, with only minor room for improvement in content organization.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient. It doesn't explain what YouTube is, what transcripts are, or how npm works. Every section provides specific, actionable information that Claude wouldn't inherently know (the defuddle CLI, the exact output format, timestamp conversion formula). | 3 / 3 |
Actionability | Provides exact CLI commands (`npx defuddle parse <url> --markdown`), a concrete timestamp conversion formula with a worked example, and a complete copy-paste-ready Markdown template for the watching guide output format. The guidelines section gives specific, measurable criteria (5-12 segments, 2-4 sentences, 1-3 quotes). | 3 / 3 |
Workflow Clarity | The watching guide workflow is clearly sequenced in 4 numbered steps (fetch → analyze → produce → save). While this isn't a destructive operation requiring validation checkpoints, the steps are unambiguous and the output format template serves as an implicit validation reference. The workflow is appropriate for the task's complexity. | 3 / 3 |
Progressive Disclosure | The content is well-organized with clear sections and headers, but the watching guide output format template is quite lengthy inline. For a skill with no bundle files, the structure is reasonable, but the detailed output template and guidelines could potentially be split into a separate reference file. Still, it's a single-file skill under ~80 lines of meaningful content, so this is borderline acceptable. | 2 / 3 |
