Quality

Content

65%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.

The body is concise and well-structured as a catalogue entry, but it provides no executable workflow or local references for the actual task, relying entirely on an external upstream pointer.

Suggestions

Inline at least a minimal executable example or command for the core clip workflow so the skill is actionable without leaving the file.

Add explicit ordered steps with a verification checkpoint (e.g., confirm the upstream bundle installed and the skill is invokable) to improve workflow clarity.

Provide local reference files (or a clear local path layout) rather than directing the agent to inspect an external GitHub repo for paths.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence, with no padded explanations of concepts Claude already knows.

3 / 3

Actionability

It offers only a generic pointer ("open https://github.com/..." and "inspect the upstream README for exact paths") rather than concrete, executable guidance for the clip workflow itself.

2 / 3

Workflow Clarity

A rough sequence is implied (install upstream, then invoke by name) but there are no explicit steps or validation checkpoints for the actual clip-generation task.

2 / 3

Progressive Disclosure

Sections are organized, but no local bundle files exist and the body defers to an external upstream URL rather than well-signaled one-level-deep local references.

Description

67%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.

The description is specific and occupies a clear niche, but it lacks an explicit trigger clause, leaving the "when to use" half implicit and capping completeness.

Suggestions

Add a "Use when ..." clause naming natural user phrases (e.g., YouTube clips, video highlights, shorts) to satisfy completeness and trigger-term quality.

Include common trigger variations like "video highlights" or "shorts" alongside "YouTube clip" to broaden natural-term coverage.

DimensionReasoningScore

Specificity

The description lists multiple concrete actions — "pull source video, slice highlights, add captions, and export" — matching the top anchor for specific capabilities.

3 / 3

Completeness

It clearly answers "what" the skill does, but there is no explicit "when to use" clause; per the guidelines a missing trigger clause caps completeness at 2.

2 / 3

Trigger Term Quality

"YouTube clip generation and editing" surfaces some relevant natural terms, but the description omits common user variations (e.g., "video highlights", "shorts") and has no "Use when..." trigger phrasing.

2 / 3

Distinctiveness Conflict Risk

The YouTube clip-editing niche with specific actions is clearly distinguishable and unlikely to fire for unrelated skills.
