Content

78%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is highly actionable and well-structured, with concrete commands and a clear multi-step workflow. Its main weaknesses are a missing prompts/speaker-transcript.md reference file and minor conciseness/numbering issues in the workflow section.

Suggestions

Add the missing prompts/speaker-transcript.md file referenced in the Speaker Identification workflow, or remove/correct the reference so navigation is not broken.

Fix the duplicate '3.' step numbering in the Workflow list and tighten the Caching section so it does not restate the output-directory tree.

Add an explicit verification checkpoint after the script run (e.g., 'confirm the printed output file path exists before post-processing') to strengthen the workflow feedback loop.

DimensionReasoningScore

Conciseness

The body is mostly lean with tables for options/inputs/outputs and no padding explaining basic concepts, but a few spots could be tightened (e.g., the Workflow list accidentally numbers two steps '3.', and caching details partly restate the output-directory tree).

4 / 5

Actionability

Provides copy-paste-ready commands with concrete flags, a full options table, accepted input formats, and an explicit output-directory tree; the ${BUN_X} and {baseDir} placeholders are clearly resolved up front.

5 / 5

Workflow Clarity

The fetch workflow is clearly sequenced with the '--list first' step, single-quoting guidance, and a detailed chapters/speakers sub-workflow, but it lacks explicit verification checkpoints (e.g., confirm the saved file path) and the numbered list has a duplicate '3.'.

4 / 5

Progressive Disclosure

Structure is reasonable with well-organized sections and a real scripts/ bundle referenced accurately, but the body points to '{baseDir}/prompts/speaker-transcript.md' which does not exist in the bundle — a broken reference that undermines navigation.

Description

100%Weight 40%Scale 1-5

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 excellent: it states concrete capabilities concisely, provides rich natural trigger terms in two languages, and explicitly covers both what the skill does and when to use it. It uses third-person voice throughout and avoids fluff.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'Downloads YouTube video transcripts/subtitles and cover images', 'Supports multiple languages, translation, chapters, and speaker identification', 'Caches raw data for fast re-formatting' — giving comprehensive coverage of the skill's capabilities.

5 / 5

Completeness

Explicitly answers both 'what' (downloads transcripts/subtitles/cover images with language/translation/chapter/speaker support and caching) and 'when' via a concrete 'Use when...' clause with multiple trigger phrases.

5 / 5

Trigger Term Quality

Comprehensive natural trigger terms including synonyms and bilingual variants — 'get YouTube transcript', 'download subtitles', 'get captions', 'YouTube字幕', 'YouTube封面', 'video thumbnail', 'video cover image' — covering phrases users would actually say.

5 / 5

Distinctiveness Conflict Risk

A clear YouTube-transcript niche with distinct, specific triggers (including bilingual terms) makes overlap with other skills minimal and conflict risk low.
