Conciseness

Every section is dense, product-specific knowledge Claude cannot already know (the override ladder, contract component lists, ejection manifest rules), written as lean imperative rules with no padding and no explanation of known concepts (React, styling runtimes are only named as options). It matches anchor 5: every token earns its place.

Actionability

Mostly copy-paste ready: the eject CLI block with flags, the `rg`/`pnpm action` search commands, and the complete `defineDesignSystem` registration example. It falls between anchors 4 and 5 because the conformance-kit snippet passes an undefined `components` binding ("components," in assertDesignSystemConformance) without the import that would make it run — a minor gap, so 4 rather than 5.

Workflow Clarity

The multi-step override ladder is explicitly sequenced (steps 1–6), and the eject workflow has full validation checkpoints: dry-run by default that prints "verification commands", gated `--apply`, hash-gated restore that "refuses to remove locally edited files... and prints their diff", an After Ejecting checklist ("Run the manifest verification commands plus the app's formatter, typecheck, and focused tests"), and feedback loops via `eject diff` to distinguish drift. Destructive/batch operations are validated, so no cap applies.

Progressive Disclosure

No bundle files exist, and the single 220-line file is cleanly sectioned with a useful Related Skills list, making navigation easy. It is not 5 because content that could live one level deep — the full 17-component contract listing and the conformance-kit details — is inlined in SKILL.md rather than split into a reference file; that fits anchor 4 ('most content is appropriately placed; minor organization gaps').

Specificity

The description lists multiple concrete actions — "configure, compose, or eject Agent-Native features into app-owned code" — plus supporting actions ("overriding shared components or integrations", "customizing a template", "adding UI to chat or headless apps", "inspecting package source"), comprehensively covering the skill's scope. It clearly matches anchor 5 rather than 4 because the action list covers the skill's full surface, not just several actions with gaps.

Completeness

It explicitly answers both parts: what ("configure, compose, or eject Agent-Native features into app-owned code") and when ("Use when overriding shared components or integrations, customizing a template, adding UI to chat or headless apps, or inspecting package source") with concrete trigger phrases. This is a direct match for anchor 5.

Trigger Term Quality

Good natural-phrase coverage: "customizing a template", "adding UI to chat", "overriding shared components", "inspecting package source" are phrases a user would plausibly say. Not 5 because a central trigger concept from the body — "design system" / company-component registration (e.g., 'use our MUI/brand components') — is absent as a keyword; not 3 because coverage is well beyond 'some relevant keywords'.

Distinctiveness Conflict Risk

"Agent-Native" names a clear niche with distinct triggers (eject, chat/headless apps), but "inspecting package source" overlaps with the related `agent-native-docs` skill ("version-matched docs and source lookup"), giving minor overlap risk with a closely related skill — anchor 4.
