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

70%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 body is highly actionable with a well-validated render workflow and good reference scaffolding, but it loses points for a duplicated OD workflow explanation, one broken script path, and four dead reference-file links. Fixing the broken references and de-duplicating the workflow narrative would lift both conciseness and progressive disclosure.

Suggestions

Resolve dead links: visual-styles.md, house-style.md, patterns.md, and data-in-motion.md are referenced (some multiple times) but missing from the bundle — either add the files or point to existing references/ equivalents.

Fix the animation-map command path from 'design-templates/hyperframes/scripts/animation-map.mjs' to the actual 'scripts/animation-map.mjs' so the example is runnable.

De-duplicate the Open Design workflow: the prose summary at lines ~122–143 restates the scaffold bash block above it; collapse into one authoritative pass.

Dimension	Reasoning	Score
Conciseness	The body is dense and operational with no concept padding, but the OD render workflow is explained twice (the full bash block then a prose restatement) and the Visual Identity Gate is stated and then re-explained for OD, so it could be tightened beyond minor trimming.	3 / 5
Actionability	Mostly executable: full scaffold bash with exit-code-aware wait-loop, copy-paste GSAP/CSS examples, and data-attribute tables — but the animation-map command points at 'design-templates/hyperframes/scripts/animation-map.mjs' which does not exist in the bundle (actual: scripts/animation-map.mjs), so that command is not runnable as written.	4 / 5
Workflow Clarity	The OD render workflow is a clearly numbered sequence (slot → init → edit → dispatch → wait-loop) with explicit validation/feedback (exit codes 0/2/5, stderr-on-failure, plus lint/validate/inspect re-run loops and an Output Checklist), matching the explicit-checkpoints anchor.	5 / 5
Progressive Disclosure	Structure is sound with a 'References (loaded on demand)' section and per-file 'Read when…' triggers, but four referenced files are absent from the bundle (visual-styles.md, house-style.md, patterns.md, data-in-motion.md) and the animation-map script path is wrong, so navigation leads nowhere for those entries.	3 / 5

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.

The description is specific, trigger-rich, complete, and distinct: it names many concrete capabilities, gives explicit 'Use when…' triggers with synonyms, and cleanly scopes itself against a sibling CLI skill. It is a strong, model-dispatch-friendly description.

Dimension	Reasoning	Score
Specificity	Lists many concrete actions across sub-features ('video compositions, animations, title cards, overlays, captions, voiceovers, audio-reactive visuals, and scene transitions') with granular detail (marker sweeps, hand-drawn circles, crossfades, shader transitions), matching the comprehensive-coverage anchor.	5 / 5
Completeness	Explicitly answers both 'what' ('Create video compositions… in HyperFrames HTML') and 'when' ('Use when asked to build any HTML-based video content…') with concrete trigger phrases, matching the top anchor.	5 / 5
Trigger Term Quality	Covers natural user phrases ('captions or subtitles synced to audio', 'text-to-speech narration', 'transitions between scenes') plus synonyms and concrete effect names, matching comprehensive natural-term coverage.	5 / 5
Distinctiveness Conflict Risk	Tight HyperFrames/HTML-video niche with an explicit handoff to the sibling hyperframes-cli skill ('For CLI commands… see the hyperframes-cli skill'), giving a clear niche with minimal conflict risk.	5 / 5
