Quality

Content

100%

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

The content is a tight, fully actionable reference with well-organized sections and no unnecessary padding, well-suited to a simple single-purpose CLI skill.

DimensionReasoningScore

Conciseness

The body is lean: terse Quick start commands, a compact flag list, and short env-var/config sections with no explanation of concepts Claude already knows, so every token earns its place.

3 / 3

Actionability

It provides fully executable, copy-paste-ready commands (e.g., `summarize "https://youtu.be/..." --youtube auto --extract-only`), concrete flag values, named env vars, and a config JSON example.

3 / 3

Workflow Clarity

As a simple single-task skill with an unambiguous core action, plus a small decision flow for oversized transcripts (return a summary first, then ask which section to expand), it meets the simple-skill allowance for a 3.

3 / 3

Progressive Disclosure

No bundle files exist (references/scripts/assets absent) and none are needed; the well-organized sections (When to use, Quick start, YouTube, Model + keys, Useful flags, Config) satisfy the under-50-lines/no-external-refs allowance for a 3.

Description

82%

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, distinctive, and uses natural trigger phrasing, but it omits an explicit "Use when..." clause, leaving the invocation timing implied rather than stated.

Suggestions

Add an explicit 'Use when...' clause naming the trigger scenarios (e.g., 'Use when the user asks to summarize a URL/article, extract a transcript from a YouTube/video, or summarize a podcast or local file').

Broaden trigger term coverage with common variations like 'article', 'summarize this link', or 'TL;DR'.

DimensionReasoningScore

Specificity

"Summarize or extract text/transcripts from URLs, podcasts, and local files" lists multiple concrete actions (summarize, extract text/transcripts) tied to specific source types, matching the anchor for listing multiple specific concrete actions.

3 / 3

Completeness

It clearly states what the skill does but lacks an explicit "Use when..." clause; the when is only implied via the parenthetical "great fallback for 'transcribe this YouTube/video'", which per the guidelines caps completeness at 2.

2 / 3

Trigger Term Quality

Natural phrasing a user would actually say appears directly: "transcribe this YouTube/video", "summarize", "URLs", "podcasts", giving good coverage of natural terms.

3 / 3

Distinctiveness Conflict Risk

The summarization/transcription niche with distinct YouTube/video triggers is clearly distinguishable and unlikely to fire for unrelated skills.
