Takes an existing screen recording or demo video and adds professional zoom/pan effects synchronized to the narration. Uses transcript-driven zoom targeting and Remotion for rendering. Optionally replaces audio with a soundtrack.

Quality

Content

77%

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

The body is highly actionable with a well-sequenced, validation-rich workflow and executable code throughout. Its weaknesses are length that could be tightened and a monolithic structure that does not use progressive disclosure to split detailed reference material into separate files.

Suggestions

Move the full Remotion composition (Root.tsx/Composition.tsx) and the keyframe design rules into a reference file referenced one level deep, keeping SKILL.md a concise overview.

Tighten the explanatory prose around steps and consolidate the Supported Inputs / Audio Options / Output Specifications tables to reduce token usage without losing clarity.

Dimension	Reasoning	Score
Conciseness	Most content is non-obvious domain guidance (keyframe timing rules, coordinate grid measurement, Remotion specifics) rather than concepts Claude already knows, but at ~365 lines with multiple tables and explanatory prose it is long and could be tightened, fitting 'mostly efficient but could be tightened'.	2 / 3
Actionability	It provides executable, copy-paste-ready commands (ffprobe, ffmpeg, whisper-cli, remotion still/render), a complete Python grid-overlay snippet, and a full TSX composition with interpolation — matching the 'fully executable code/commands; copy-paste ready' anchor.	3 / 3
Workflow Clarity	A clear 9-step sequence includes an explicitly CRITICAL still-frame verification step with a render→self-review→adjust→re-render feedback loop and a 'common coordinate mistakes' checklist, matching the anchor for explicit validation steps with feedback loops.	3 / 3
Progressive Disclosure	Sections are well-organized with clear headers, but the skill is a single monolithic ~365-line file with no bundle files and no one-level-deep references; content like the full Remotion composition and keyframe design rules that could live in separate reference files is inline, fitting the 'some structure but content that should be separate is inline' anchor.	2 / 3

Description

67%

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 specific and distinctive, clearly stating what the skill does in third person with concrete capabilities. Its main weakness is the absence of an explicit 'Use when...' trigger clause and incomplete coverage of natural trigger terms like 'Loom'.

Suggestions

Add an explicit 'Use when...' clause naming natural trigger situations, e.g. 'Use when polishing a screen recording, Loom, or product demo with narration-synchronized zoom effects.'

Broaden trigger term coverage by including 'Loom' and 'walkthrough' alongside 'screen recording' and 'demo video'.

Dimension	Reasoning	Score
Specificity	The description lists multiple concrete actions — "adds professional zoom/pan effects synchronized to the narration", "transcript-driven zoom targeting", "Remotion for rendering", "Optionally replaces audio with a soundtrack" — matching the anchor for listing multiple specific concrete actions.	3 / 3
Completeness	It clearly answers 'what does this do' with specific capabilities, but there is no 'Use when...' clause or equivalent explicit trigger guidance for when to invoke it; per the judging guidelines, a missing trigger clause caps completeness at 2.	2 / 3
Trigger Term Quality	"screen recording", "demo video", and "zoom/pan" are natural terms a user might say, but coverage is incomplete — common variations like "Loom" and "walkthrough" that appear in the body are absent, so it stops at 'some relevant keywords but missing common variations'.	2 / 3
Distinctiveness Conflict Risk	"zoom/pan effects synchronized to the narration" via "transcript-driven zoom targeting" and "Remotion" carves out a clear niche unlikely to trigger for unrelated skills, matching the 'clear niche with distinct triggers' anchor.	3 / 3
