Conciseness

The Bun-specific material (presets, bun:sqlite, `bun --bun`, oven/bun Docker, secure installation) is lean and code-first, but a substantial middle chunk is generic Nuxt/H3 knowledge Claude already has — the "H3 Event Handling" tour of readBody/getQuery/getCookie/setCookie, the auth middleware, the useFetch composable, and server plugins examples contain nothing Bun-specific. Several sections could be cut or trimmed without losing skill value, fitting anchor 3's "mostly efficient but includes some unnecessary explanation".

Actionability

Nearly every section is copy-paste-ready: the Quick Start command sequence, exact package.json script variants for Bun, a complete nuxt.config.ts with the Bun preset, working bun:sqlite server routes, a scheduled-task example, a full multi-stage Dockerfile, and runtimeConfig wiring. The common-cases coverage is concrete and executable throughout, matching anchor 5.

Workflow Clarity

The Quick Start and Deployment sections present clear ordered sequences (init → install → dev → build → preview; build → run; Docker stages), and the Common Errors table gives error-to-fix recovery guidance. However, there are no explicit validation checkpoints (e.g., verifying the build output before deploying), keeping it at anchor 4 rather than 5.

Progressive Disclosure

The ~355-line body is well-sectioned and ends with a clearly signaled "When to Load References" section, but the two referenced files (references/nitro.md, references/deployment.md) do not exist in the bundle — the pointers are dangling. Meanwhile content that belongs in those references (server utilities, Nitro features, deployment detail) is inlined, matching anchor 3's structure-present-but-should-be-split; the broken references are the main reason it does not reach 4.

Specificity

The description names the domain concretely ("Nuxt 3 with Bun runtime", "Vue/Nuxt apps") and lists three actions — running, building, and configuring — though the verbs themselves remain fairly high-level rather than enumerating concrete operations like Bun presets or bun:sqlite. It sits above anchor 3 (only 1-2 actions) but below anchor 5's comprehensive action coverage.

Completeness

The "what" is only implied through the gerunds inside the "Use when..." clause (running/building/configuring Nuxt with Bun) rather than stated as a separate capability sentence, while the "when" is explicit with three concrete triggers. This matches anchor 4 — both present, one could be more explicit — and falls short of anchor 5's clearly separated what-and-when.

Trigger Term Quality

Natural terms users would say are well covered: "Nuxt 3", "Bun", "Bun runtime", "Vue/Nuxt apps", "development and production". A few plausible natural phrases are missing (e.g., "bunx", "nuxi", Nitro), keeping it below the comprehensive synonym coverage of anchor 5.

Distinctiveness Conflict Risk

The Nuxt-plus-Bun intersection is a clear niche with distinct triggers; it is unlikely to fire for generic Vue, Node, or Bun-only requests. Minor overlap with a hypothetical pure-Nuxt or pure-Bun skill exists but the pairing constraint keeps conflict risk minimal.
