Quality

Content

100%Weight 40%Scale 1-3

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

A well-structured CLI skill body: concise, fully actionable examples, a clear step-by-step workflow, and clean single-file organization with no unnecessary concept explanations. It respects Claude's competence while providing concrete, executable guidance.

Dimension	Reasoning	Score
Conciseness	The body is lean and reference-style: executable commands, tables, and flag lists with almost no explanation of concepts Claude already knows; each scenario demonstrates a distinct capability and every token earns its place.	3 / 3
Actionability	Commands are fully executable and copy-paste ready with real flags (e.g. 'videocaptioner process video.mp4 --asr bijian --translator bing --target-language en --subtitle-mode hard --quality high -o output.mp4'), backed by a command-reference table.	3 / 3
Workflow Clarity	Scenario 6 lays out a clear transcribe → translate → synthesize sequence, and the pipeline is non-destructive so the destructive/batch validation cap does not apply; exit codes are documented for error recovery.	3 / 3
Progressive Disclosure	A single, well-organized SKILL.md with clear section headers (When to use, Common scenarios, Command reference, Subtitle styles) and no nested references; content is appropriately self-contained with easy navigation.	3 / 3
	Total	12 / 12 Passed

Description

100%Weight 40%Scale 1-3

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that states concrete capabilities and pairs them with natural, explicit use-when triggers. It is concise, distinct, and answers both what the skill does and when to invoke it.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'transcribe speech, optimize/translate text, burn styled subtitles into video' — matching the score-3 anchor of enumerating specific operations rather than vague verbs.	3 / 3
Completeness	Explicitly answers both 'what' (transcribe/optimize/translate/burn) and 'when' via a 'Use when...' clause with explicit triggers, matching the score-3 anchor.	3 / 3
Trigger Term Quality	Triggers 'add subtitles to a video, transcribe audio, translate subtitles, or customize subtitle styles' are natural phrasings a user would actually say, with good coverage of common variations.	3 / 3
Distinctiveness Conflict Risk	Occupies a clear niche (video subtitling) with distinct triggers unlikely to collide with other skills; not above 3 on the scale and clearly above the score-2 'could still overlap' anchor.	3 / 3
	Total	12 / 12 Passed
