Conciseness

The body is a ~1,300-line dump of an entire documentation site and meets all three conditions of anchor 1: severely verbose (11 concatenated doc pages), extensively explaining concepts Claude already knows (accessibility basics like contrast ratios and label/htmlFor pairing, controlled vs uncontrolled state, polymorphism and cloneElement mechanics), and heavily padded ('URL: /accessibility' lines, per-page duplicated title/description blocks, a video embed, author callouts, and an Overview page about the spec itself). Anchor 2 ('several unnecessary explanations') understates the scale of the padding, so 1 fits better than 2.

Actionability

Most sections provide concrete, executable TSX: the full Accordion Root/Item/Trigger/Content composition walkthrough, the Radix Slot implementation with cva variants, the useControllableState example with install commands, and ComponentProps type patterns with good/bad contrasts. It falls short of anchor 5 because some guidance is only descriptive (Design Tokens and Data Attributes sections defer to 'react.mdc', a file not present in the bundle, so those pointers are unusable) and several examples are illustrative fragments rather than complete copy-paste units.

Workflow Clarity

There is no workflow for the skill's stated purpose — creating/updating a composable component — only the Composition section's rough build-out sequence (1. Root, 2. Item, 3. Trigger, 4. Content, 5. Putting it together). No validation or verification checkpoints exist (e.g. verifying ARIA wiring, prop forwarding, or type safety), and the sections are unordered concatenated pages with no decision path. This sits between anchor 1 (steps missing or incoherent, no validation) and anchor 2 (rough sequence, many gaps, validation absent), closer to 2 given the Composition walkthrough.

Progressive Disclosure

The skill is monolithic: all eleven topic areas (Accessibility, asChild, Composition, Data Attributes, Definitions, Design Tokens, Overview, Polymorphism, Core Principles, State, Types) are inlined in one 1,300-line file with no references/, scripts/, or assets/ directories, and the body points to 'react.mdc' which does not exist in the bundle. This matches anchor 2 (content that clearly belongs in separate files is inlined) rather than anchor 1, since the body does have per-topic section headers making it navigable.

Specificity

The description names the domain ('React component architecture') and a couple of concrete qualities ('composable, accessible components with data attributes'), but these are attributes of the output rather than a list of specific actions the skill performs. This matches anchor 3 (domain plus 1-2 concrete points, not comprehensive) rather than anchor 4, which expects several specific actions enumerated; it is clearly above anchor 2 since the domain is well identified and the named qualities are concrete.

Completeness

Both parts are explicitly present: a clear 'what' ('React component architecture for creating composable, accessible components with data attributes') and an explicit 'when' ('Use when creating/updating composable components, not for higher-level feature/page components') that even includes negative scoping. It falls short of anchor 5 because the trigger guidance lacks concrete trigger phrases or scenario variations, matching anchor 4 ('when' could be more explicit or specific).

Trigger Term Quality

Relevant keywords are present ('React component', 'composable components', 'creating/updating'), but common natural variations a user would actually say are missing — e.g. 'UI components', 'component library', 'design system', 'shadcn/Radix', or file extensions. This fits anchor 3 (some relevant keywords, missing common variations or synonyms) and not anchor 4, which requires good coverage with only a few natural terms missing.

Distinctiveness Conflict Risk

The scope is fairly narrow (composable/accessible React components with data attributes) and the explicit negative boundary ('not for higher-level feature/page components') reduces overlap with page/feature-level skills. Minor overlap risk remains with general React or styling skills ('components' alone is broad), so this is anchor 4 rather than anchor 5, which demands a clear niche with minimal conflict risk.
