Quality

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.

The description effectively communicates core capabilities and includes good natural trigger terms, especially the YouTube/video fallback note. However, it lacks an explicit 'Use when...' clause and could be more specific about what distinguishes it from general summarization or text extraction skills.

Suggestions

Add an explicit 'Use when...' clause, e.g., 'Use when the user wants to transcribe, summarize, or extract content from web pages, audio files, podcasts, or video URLs.'

Clarify the scope to improve distinctiveness, e.g., specify supported formats (.mp3, .wav) or platforms (YouTube, Spotify podcasts) to reduce overlap with generic text extraction skills.

DimensionReasoningScore

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 explicit 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 'summarize' and 'extract text' could overlap with general text processing or document skills. The YouTube/video mention helps but scope is still broad.

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 well-crafted skill that efficiently documents a CLI tool with concrete, executable examples. The content is appropriately concise and assumes Claude's competence. Minor improvement could be made to the workflow around handling large YouTube transcripts, which is mentioned but not fully sequenced.

Suggestions

Add explicit steps for the large transcript workflow: 1) attempt extraction, 2) if >X chars, summarize first, 3) ask user for section/time range, 4) re-extract with range

DimensionReasoningScore

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 for all common use cases. Concrete examples with real flags, environment variable names, and config file format are all executable.

3 / 3

Workflow Clarity

For a simple CLI wrapper this is mostly clear, but the YouTube transcript workflow could benefit from explicit steps for handling the 'huge transcript' scenario mentioned. The trigger phrases section is helpful but the decision flow between summary vs transcript isn't fully sequenced.

2 / 3

Progressive Disclosure

Well-organized with clear sections progressing from quick start to specific use cases to configuration. For a simple CLI skill under 50 lines, the structure is appropriate without needing external file references.
