hyperframes

Create video compositions, animations, title cards, overlays, captions, voiceovers, audio-reactive visuals, and scene transitions in HyperFrames HTML. Use when asked to build any HTML-based video content, add captions or subtitles synced to audio, generate text-to-speech narration, create audio-reactive animation (beat sync, glow, pulse driven by music), add animated text highlighting (marker sweeps, hand-drawn circles, burst lines, scribble, sketchout), or add transitions between scenes (crossfades, wipes, reveals, shader transitions). Covers composition authoring, timing, media, and the full video production workflow. For CLI commands (init, lint, preview, render, transcribe, tts) see the hyperframes-cli skill.

Quality

Content

77%Weight 40%Scale 1-3

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 executable code and a clear, validated workflow, but it is slightly verbose in places and references several root-level files that are absent from the bundle. Fixing the missing references and trimming explanatory prose would lift the two weaker dimensions.

Suggestions

Add the missing root-level reference files referenced as essential (house-style.md, visual-styles.md, patterns.md, data-in-motion.md) or update the body links to point at files that exist in the bundle.

Tighten or remove explanatory prose blocks (e.g. 'Why this matters' and guardrail rationales) so the body earns every token, lifting conciseness.

Consider moving the longest inline detail (e.g. the full Scene Transitions rule block or Quality Checks) into a one-level reference if it grows, to keep SKILL.md a lean overview.

Dimension	Reasoning	Score
Conciseness	The body is mostly lean (rules, attribute tables, executable code) and avoids explaining concepts Claude already knows, but several explanatory prose blocks ('Why this matters', guardrail rationales) could be tightened further, fitting the 'mostly efficient but could be tighter' anchor rather than fully lean.	2 / 3
Actionability	Provides fully executable HTML/JS/CSS snippets, exact data-attribute tables, specific CLI commands ('npx hyperframes lint', 'npx hyperframes validate'), and concrete guardrails with code, making it copy-paste ready.	3 / 3
Workflow Clarity	Clear sequenced process (What -> Structure -> Timing -> Layout -> Animate), a numbered 'Layout Before Animation' procedure, an Output Checklist, and validation feedback loops (lint -> validate -> inspect, re-run until clean) with explicit checkpoints.	3 / 3
Progressive Disclosure	The References section is well organized and one-level-deep with 'Read when...' signals, but four root-level referenced files (visual-styles.md, house-style.md, patterns.md, data-in-motion.md) are missing from the bundle despite the body marking house-style.md/typography as 'always read', which breaks navigation and keeps this below the well-signaled/complete anchor.	2 / 3

Description

100%Weight 40%Scale 1-3

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, trigger-rich, and cleanly answers both what the skill does and when to use it, while explicitly distinguishing it from the companion CLI skill. It uses third-person voice with no fluff or over-claims.

Dimension	Reasoning	Score
Specificity	Lists many concrete actions ('Create video compositions, animations, title cards, overlays, captions, voiceovers, audio-reactive visuals, and scene transitions') plus granular sub-examples ('marker sweeps, hand-drawn circles, burst lines, scribble, sketchout'), matching the 'multiple specific concrete actions' anchor.	3 / 3
Completeness	Explicitly answers both 'what' (the opening verb list) and 'when' via a clear 'Use when...' clause with concrete triggers, satisfying the 'both what AND when' anchor.	3 / 3
Trigger Term Quality	Natural user-facing terms are well covered ('video content', 'captions or subtitles synced to audio', 'text-to-speech narration', 'audio-reactive animation', 'transitions between scenes'), the kind of phrasing a user would actually say.	3 / 3
Distinctiveness Conflict Risk	Occupies a clear niche (HTML-based HyperFrames video) and explicitly routes CLI concerns to a separate 'hyperframes-cli' skill, making wrong-skill triggering unlikely.	3 / 3
	Total	12 / 12 Passed
