Conciseness

The body is lean and assumes competence: no explanation of what HTML, GSAP, or registries are; every section delivers commands, code, or a tightly-scoped note (e.g. 'hyperframes add only works for blocks and components. For examples, use hyperframes init'). Each of the ~100 lines earns its place; not score 4 because there is no identifiable over-explanation to trim.

Actionability

Fully executable guidance throughout: copy-paste bash commands with flags ('hyperframes add data-chart --json', '--no-clipboard'), a complete JSON config block, a complete HTML wiring snippet, and a concrete numbered 5-step procedure for component merging. The common cases (install a block, install a component, wire each) are each covered with specific examples; not score 4 because nothing requires the reader to fill in missing details.

Workflow Clarity

Sequences are clear — install (CLI prints which files were written, plus the snippet to paste) then wire blocks (attribute table) or components (numbered steps), and wiring includes the correctness constraint 'must match the block's internal composition ID'. However, no explicit validation/verify step exists after wiring or installing (no 'preview/confirm the composition renders' checkpoint), matching the anchor for clear sequence with minor validation gaps rather than the anchor-5 explicit validation steps and feedback loops.

Progressive Disclosure

The body is a well-structured overview with clearly signaled one-level-deep references to real files (install-locations.md, wiring-blocks.md, wiring-components.md, discovery.md, contributing.md, templates.md), each placed exactly at its topic. However, the bundle file references/demo-html-pattern.md is never referenced from SKILL.md or any other reference file — an orphaned resource that is hard to discover — which is a minor organization gap matching anchor 4 rather than the fully navigable anchor 5.

Specificity

The description lists multiple concrete actions — 'Install and wire registry blocks and components', 'running hyperframes add', 'wiring an installed item into index.html', 'working with hyperframes.json' — and comprehensively enumerates coverage: 'the add command, install locations, block sub-composition wiring, component snippet merging, registry discovery, and authoring a new block or component'. This matches the anchor for multiple specific concrete actions with comprehensive coverage; not score 4 because there are no minor gaps in the enumerated capabilities.

Completeness

It explicitly answers 'what' ('Install and wire registry blocks and components into HyperFrames compositions' plus a coverage sentence) and 'when' with concrete trigger phrases ('Use when running hyperframes add, installing a block or component, wiring an installed item into index.html, or working with hyperframes.json'). This directly matches the anchor-5 example structure; the 'Use when...' clause is explicit and specific, so the cap of 3 does not apply.

Trigger Term Quality

Natural trigger terms cover the full space: the command ('hyperframes add'), the artifacts ('block', 'component', 'hyperframes.json', 'index.html'), and the activities ('installing', 'wiring', 'registry discovery', 'contribute upstream'). These mirror what a user would actually say; not score 4 because no commonly used phrasing for this domain is conspicuously missing.

Distinctiveness Conflict Risk

The niche is unambiguous — a specific tool ('HyperFrames', 'hyperframes add', 'hyperframes.json') with registry-specific vocabulary — so it is clearly distinguishable from other skills and unlikely to trigger for the wrong one. Not score 4: the domain-specific tool and file names give it minimal overlap risk with any generic skill.
