remotion

Create editable AI video projects with Remotion and React, then preview and render them to MP4. Use for vertical short videos, product demos, story-driven animations, HUD/tech visuals, feed ads, tutorial videos, subtitles, voiceover, sound effects, and code-based video iteration.

Quality

Content

85%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.

A well-structured, executable skill body: setup, an eight-step workflow with concrete commands, terse implementation guidelines, an explicit validation section with error-recovery guidance, and a delivery checklist. The only notable improvement would be a minimal worked composition/code example to make scene assembly fully concrete and trimming the description-repeating opening.

DimensionReasoningScore

Conciseness

Lean and imperative with no tutorial-style padding about what Remotion or React is; however, the two opening paragraphs and the 'Good fits include...' list partly restate the frontmatter description's triggers and could be trimmed.

4 / 5

Actionability

Copy-paste-ready commands throughout ('npx create-video@latest --yes --blank --no-tailwind my-video', 'npx remotion still <composition-id> --scale=0.25 --frame=30') plus named primitives ('Composition', 'Sequence', 'useCurrentFrame', 'spring'), but there is no worked composition example showing how a scene or caption component is actually assembled — a minor gap against fully executable coverage.

4 / 5

Workflow Clarity

An eight-step numbered workflow with explicit validation checkpoints in the Checks section ('npm run build', a still-frame render 'to catch layout, color, and timing issues', and the final render), an error-recovery loop ('If rendering fails because of missing browser, FFmpeg, codec, or dependency setup, report the blocker and run the relevant Remotion or environment diagnostic before retrying'), and a Delivery checklist.

5 / 5

Progressive Disclosure

No bundle files exist, and everything present is appropriately inline at overview scale: clean, navigable sections (Setup, Workflow, Implementation Guidelines, Checks, Delivery) with no buried references or bulk content that belongs in a separate file.

Description

87%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 clearly states what the skill does (create, preview, render MP4 via Remotion/React) and when to use it, with an explicit 'Use for' clause covering diverse natural trigger scenarios. Only minor gaps: editing is implied rather than stated as an action, and a few common synonyms ('captions', 'Shorts/Reels') are absent.

DimensionReasoningScore

Specificity

Concrete actions are named — 'Create editable AI video projects with Remotion and React', 'preview', 'render them to MP4' — but editing is expressed only as the adjective 'editable' rather than a distinct named action (e.g., 'edit subtitles, timing, audio'), leaving a minor coverage gap versus the comprehensive anchor.

4 / 5

Completeness

Explicitly answers both questions: the 'what' ('Create editable AI video projects with Remotion and React, then preview and render them to MP4') and the 'when' via a concrete 'Use for...' clause listing ten trigger scenarios, matching the top anchor's structure.

5 / 5

Trigger Term Quality

Rich natural phrasing users would actually say — 'vertical short videos', 'product demos', 'subtitles', 'voiceover', 'sound effects', 'MP4' — but common synonyms and platform terms like 'captions', 'Shorts/Reels/TikTok', or 'animated video' are missing, so coverage is good rather than comprehensive.

4 / 5

Distinctiveness Conflict Risk

Clear niche — code-based video via 'Remotion and React' rendering to 'MP4' with 'code-based video iteration' — and triggers like HUD visuals and feed ads would not plausibly fire a prompt-only video or general media skill, so conflict risk is minimal.
