video-editing

AI-assisted video editing workflows for cutting, structuring, and augmenting real footage. Covers the full pipeline from raw capture through FFmpeg, Remotion, ElevenLabs, fal.ai, and final polish in Descript or CapCut. Use when the user wants to edit video, cut footage, create vlogs, or build video content.

Quality

Content

72%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.

The content is highly actionable and concisely written with executable code throughout, but workflow clarity is capped by missing validation on batch/destructive FFmpeg operations, and progressive disclosure is limited by inlining everything in one large file.

Suggestions

Add validation checkpoints after batch FFmpeg operations: e.g., probe each output segment with ffprobe to confirm duration, and verify concat succeeded before treating assembled.mp4 as final.

Split the full Remotion composition and the FFmpeg command catalog into separate reference files (e.g., REMOTION.md, FFMPEG.md) referenced one level deep from SKILL.md to improve progressive disclosure.

Tighten editorial commentary in 'Core Thesis' and 'Key Principles' to remove phrases that restate what the code already shows.

DimensionReasoningScore

Conciseness

The body is lean and code-forward, assuming Claude knows the tools without explaining them, but a few punchy editorial lines ('This is where taste lives', 'FFmpeg handles the boring but critical work') could be trimmed.

4 / 5

Actionability

Provides copy-paste-ready FFmpeg commands, a full Remotion TSX composition, and Python snippets for ElevenLabs/VideoDB that cover the common cases end-to-end.

5 / 5

Workflow Clarity

The six-layer pipeline is clearly sequenced, but the batch cut loop and concat operations are destructive/batch workflows with no validation or verification checkpoints, which caps this dimension at 3 per the rubric.

3 / 5

Progressive Disclosure

Content is well-sectioned by layer, but it is a single ~310-line monolithic file with full code compositions and reference tables inlined rather than split into one-level-deep reference files.

Description

88%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.

The description is strong: it names concrete actions, an explicit toolchain, and clear natural-language trigger phrases that distinguish editing real footage from generation. Minor gaps are missing synonyms/extensions and a small overlap risk with generation skills.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ('cutting, structuring, and augmenting real footage') and comprehensively names the pipeline tools (FFmpeg, Remotion, ElevenLabs, fal.ai, Descript, CapCut), matching the comprehensive-coverage anchor.

5 / 5

Completeness

Explicitly states what it does (cutting/structuring/augmenting real footage through a named pipeline) and gives a concrete 'Use when the user wants to edit video, cut footage, create vlogs, or build video content' trigger.

5 / 5

Trigger Term Quality

'edit video, cut footage, create vlogs, or build video content' are natural phrases users would say, but synonyms (trim, clips) and file extensions are missing, placing it just below the comprehensive anchor.

4 / 5

Distinctiveness Conflict Risk

Has a clear niche (editing real footage, explicitly not generation) with distinct triggers, but 'build video content' mildly overlaps the fal-ai-media generation skill, so not fully minimal conflict risk.
