hyperframes-core

The HyperFrames composition contract — build one renderable project. Use for composition structure, the `data-*` timing attributes, `class="clip"`, tracks, sub-compositions, variables, framework-owned media playback, deterministic-render rules, and validation. Also covers Tailwind projects and the STORYBOARD.md / SCRIPT.md plan formats. Read before writing composition HTML.

Quality

Content

78%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 technical contract: lean, concrete, and exemplary in its progressive disclosure via a purpose-mapped references table. The main improvement is making the build flow a more explicit numbered sequence with validation checkpoints.

Suggestions

Convert the 'Building a composition' section into an explicitly numbered end-to-end sequence with validation checkpoints between stages (e.g., after sizing, after timeline registration, before lint).

Inline a minimal complete composition skeleton so the core example is copy-paste ready without first opening references/minimal-composition.md.

DimensionReasoningScore

Conciseness

Dense and technical, assuming Claude's competence without explaining basics; a few explanatory asides (transport rule, host-id convention) could be trimmed slightly but mostly earn their tokens.

4 / 5

Actionability

Concrete guidance throughout — specific lint error codes, executable patterns like `gsap.fromTo(el, { x: -40 }, { x: 0 })`, and CLI commands (`npx hyperframes check`); a full inline composition example is delegated to a reference rather than shown.

4 / 5

Workflow Clarity

Validation section provides an explicit checklist with approval gating and a feedback loop ('Clear lint errors before you trust those numbers'); the build section is topical rather than a strictly numbered sequence, leaving minor checkpoint gaps.

4 / 5

Progressive Disclosure

A clear References table maps each of 18 real bundle files to a 'Read it to…' purpose at one level of depth; the body is an overview/contract with details correctly split into references/.

Description

92%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, specific description that clearly states both capability and trigger conditions with concrete domain terms. Minor room to soften jargon-laden phrases into more user-natural language.

Suggestions

Replace or supplement jargon phrases like 'deterministic-render rules' and 'framework-owned media playback' with terms a user would naturally say (e.g., 'reproducible/seekable renders', 'letting the framework handle video/audio playback').

Consider adding common synonyms users might say (e.g., 'video', 'render', '.html') to broaden natural trigger coverage.

DimensionReasoningScore

Specificity

Lists multiple concrete capabilities — composition structure, `data-*` timing attributes, `class="clip"`, tracks, sub-compositions, variables, media playback, deterministic-render rules, validation — giving comprehensive coverage rather than vague abstraction.

5 / 5

Completeness

Explicitly answers both 'what' ('build one renderable project' + enumerated capabilities) and 'when' ('Use for …', 'Read before writing composition HTML') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Good natural-term coverage ('composition', 'tracks', 'sub-compositions', 'Tailwind projects', 'STORYBOARD.md', 'SCRIPT.md', 'composition HTML'), though some phrasing like 'deterministic-render rules' and 'framework-owned media playback' is jargon over natural user speech.

4 / 5

Distinctiveness Conflict Risk

Scoped to a clear niche ('The HyperFrames composition contract') with domain-specific triggers, making conflict with unrelated skills minimal.
