Quality

Content

100%

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

A tight, actionable reference of executable ffmpeg recipes with clean sectioning and a single well-signaled deeper reference. It assumes Claude's intelligence, stays copy-paste ready, and avoids verbosity.

DimensionReasoningScore

Conciseness

Lean, code-first body that assumes ffmpeg competence and avoids explaining concepts Claude already knows; every section earns its place, though the scale filter is lightly repeated across the Resize section and the Presets table.

3 / 3

Actionability

Every recipe is a fully executable, copy-paste-ready ffmpeg/ffprobe command with concrete inputs and outputs rather than pseudocode.

3 / 3

Workflow Clarity

Independent single-action commands are unambiguous, and the concat recipe shows a clearly numbered two-step sequence; these non-destructive operations do not require validation feedback loops.

3 / 3

Progressive Disclosure

SKILL.md is a well-organized overview with a clearly signaled one-level-deep reference ("see references/operations.md"), and operations.md exists and provides the detailed recipes.

Description

100%

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, concise description that states concrete capabilities in third person and pairs them with an explicit numbered 'Use when' trigger list. It clearly signals both what the skill does and when to invoke it.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — "Trim, concat, resize, speed, overlay, extract audio, compress, and convert" — matching the anchor for comprehensive specific actions.

3 / 3

Completeness

Explicitly answers both what ("Edit videos locally using ffmpeg" plus action list) and when ("Use when: (1)...(7)...") with explicit triggers.

3 / 3

Trigger Term Quality

Uses natural terms a user would say (trim, cut, concat, resize, compress, convert) with good coverage rather than technical jargon.

3 / 3

Distinctiveness Conflict Risk

Has a clear niche (local ffmpeg video editing) with distinct triggers unlikely to fire for unrelated skills.
