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 body is a model of brevity and actionability: executable commands, a real backing script, and tidy sections with no padding.

DimensionReasoningScore

Conciseness

The body is lean with no explanation of concepts Claude already knows; every line is either an executable example or a directly useful note.

3 / 3

Actionability

It gives fully executable, copy-paste-ready `frame.sh` invocations with concrete arguments (--time, --out) backed by a real bundled script.

3 / 3

Workflow Clarity

This is a simple single-task skill under 50 lines where the action is unambiguous, so workflow clarity scores 3 without needing a multi-step sequence.

3 / 3

Progressive Disclosure

Well-organized Quick start and Notes sections with a single one-level-deep reference (scripts/frame.sh) that exists in the bundle.

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 concise, specific, and distinguishable, but it omits an explicit "Use when…" trigger clause, leaving the "when to use" half of completeness only implied.

DimensionReasoningScore

Specificity

"Extract frames or short clips from videos using ffmpeg" lists multiple concrete actions (frame extraction and clip extraction) and names the tool, matching the multiple-specific-actions anchor.

3 / 3

Completeness

It clearly states what the skill does but provides no "Use when…" clause or equivalent explicit trigger guidance, which caps completeness at 2 per the rubric guidelines.

2 / 3

Trigger Term Quality

"frames", "short clips", "videos", and "ffmpeg" are natural terms a user would say when requesting this skill, giving good coverage.

3 / 3

Distinctiveness Conflict Risk

Video frame/clip extraction via ffmpeg is a clear niche with distinct triggers and is unlikely to conflict with other skills.
