Quality

Content

76%Weight 40%Scale 1-5

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

Highly actionable, executable ffmpeg recipes with clean structure and a well-signaled reference file. The main gap is the absence of explicit validation checkpoints for destructive/batch operations, which caps workflow clarity.

Suggestions

Add a verification step after destructive/batch operations, e.g. run `ffprobe -v error -show_format output.mp4` to confirm the output is valid before considering the task done.

Add a brief 'Common errors' note with the most likely failure (e.g. concat fails when codecs differ and -c copy is used) and the recovery action, giving the workflow a feedback loop.

Reduce the redundancy between the inline resize example and the platform presets table, or keep the table only and reference it from the inline section.

DimensionReasoningScore

Conciseness

Lean quick-reference of executable commands with no padding about what ffmpeg/video is; the platform presets table repeats the inline filter verbatim, which is a minor redundancy that keeps it just below a 5.

4 / 5

Actionability

Every section is copy-paste-ready executable ffmpeg/ffprobe commands with real flags, covering all common cases the description promises.

5 / 5

Workflow Clarity

The concat recipe shows a sequenced two-step process, but destructive/batch operations (overwriting outputs with -y, re-encoding, concat) lack explicit validation checkpoints (e.g. ffprobe-verify output after running), so the cap for missing validation in destructive/batch operations applies.

3 / 5

Progressive Disclosure

SKILL.md is a concise overview and explicitly signals one-level-deep reference to references/operations.md for detailed recipes and flag explanations; the referenced file exists and matches.

Description

100%Weight 40%Scale 1-5

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 description that concisely states capabilities and provides an explicit, numbered 'Use when' trigger list. It is specific, natural, and clearly scoped to ffmpeg video editing.

DimensionReasoningScore

Specificity

Lists multiple concrete actions (Trim, concat, resize, speed, overlay, extract audio, compress, convert), giving comprehensive coverage of ffmpeg video operations.

5 / 5

Completeness

Explicitly answers what ('Edit videos locally using ffmpeg' + enumerated actions) and when (a numbered 'Use when' clause with seven concrete triggers).

5 / 5

Trigger Term Quality

Natural user terms appear throughout (trim, cut, concat, resize, compress, convert) plus platform-relevant phrases; 'Use when' lists trimming/cutting/concatenating/extracting/compressing that users would naturally say.

5 / 5

Distinctiveness Conflict Risk

Scoped tightly to local ffmpeg video editing with specific triggers; minimal overlap risk with unrelated skills.
