The body is dense and lean — it never explains concepts Claude already knows (what Vite, a monorepo, or CI is) and every line carries project-specific, non-obvious detail. Not a 2 because there is no padded exposition; the length reflects necessary domain specifics, not verbosity.

Concrete, copy-paste-ready guidance throughout: exact commands ("vp install && vp check && vp test", "vp migrate --agent <name>", "vp upgrade"), executable YAML/TS/diff shapes, and precise config keys ("lint.options.typeAware", "node-version-file: \".node-version\""). Not a 2 because examples are real and complete, not pseudocode.

An 11-step sequenced workflow with explicit validation checkpoints — "Verify with `vp check && vp test` before moving on" (step 5) and the end-to-end validation step (step 11). Not a 2 because validation gates are explicit, not implicit, and feedback loops are present.

The body is well-structured with clearly signaled, one-level-deep references (bootstrap.md, packages.md, monorepos.md, ci-cd.md, testing.md, commands.md, known-issues.md) and load-on-demand guidance, but the referenced files do not exist — the `references/` directory is absent, so the disclosure structure is not actually functional. Capped at 2 because the navigation leads to missing files; not a 1 because the in-body signaling and organization are sound.

Lists multiple concrete actions — "Migrate or align frontend package and monorepo repositories to Vite+" and "move CI, tests, packaging, and hooks onto the stock Vite+ workflow" — rather than vague language. Not below 3 because it names several specific actions; not a 2 since it goes beyond a single domain+action.

Explicitly answers both what ("Migrate or align frontend package and monorepo repositories to Vite+") and when via a clear "Use when the user asks to migrate to Vite+..." clause. Not a 2 because the trigger is explicit, not merely implied.

Natural user phrasings are well covered: "migrate to Vite+", "standardize on `vp`", "clean up a Vite+ setup", "move CI, tests, packaging, and hooks". Not a 2 because it spans common variations users would actually say, not just one keyword.

Vite+ and `vp` are a specific named toolchain with distinct triggers, making conflict with other skills unlikely. Not a 2 because the niche is narrow and named rather than a generic "frontend" skill.
