Conciseness

The body is compact and mostly earns its tokens, but the hedge 'consultar la documentación (oficial) de tu versión' repeats five-plus times, and 'Cómo Funciona' re-explains what Turbopack is — unnecessary explanation that could be tightened, fitting the 'mostly efficient but includes some unnecessary explanation' anchor rather than the minor-trim anchor above.

Actionability

There is concrete guidance (commands `next dev`/`next build`/`next start`, flags `--webpack`, `--no-turbopack`), but the Bundle Analyzer — the most actionable optimization tool — gives no config or flag example ('habilitarlo mediante configuración o flag experimental (ver documentación)'), and the listed commands are trivially known, leaving the guidance incomplete versus the 'mostly executable, minor gaps' anchor.

Workflow Clarity

This is a knowledge/decision skill with no multi-step process; the 'Cuándo Usar' decision guidance (Turbopack vs webpack vs production) is unambiguous and the proxy.ts naming guidance includes an explicit warning, matching the clear-sequence anchor with only minor gaps — there are no validation-needing destructive or batch operations that would cap it.

Progressive Disclosure

The body is under 50 lines, needs no external reference files, and is organized into clear sections (Cuándo Usar, Cómo Funciona, Ejemplos, Nomenclatura, Buenas Prácticas); per the rubric guideline, a sub-50-line skill with no need for external references scores 5 with well-organized sections.

Specificity

Names the domain ('Next.js 16+ y Turbopack') and a few concrete topics ('bundling incremental, caché en sistema de archivos, velocidad de desarrollo'), but describes subject matter rather than listing several specific actions the skill performs, matching the anchor for 1-2 concrete actions without comprehensiveness.

Completeness

The 'what' is clear (incremental bundling, filesystem caching, dev speed), but there is no 'Use when...' clause for invoking the skill — 'cuándo usar Turbopack frente a webpack' describes subject matter, not skill triggers, so the missing explicit trigger guidance caps completeness at 3 per the rubric guideline.

Trigger Term Quality

Good natural keyword coverage users would actually say — 'Next.js 16+', 'Turbopack', 'webpack', 'caché', 'bundling' — but misses common variations like 'HMR', 'build lento', or '.next', so it is not the comprehensive synonym/extension coverage of the top anchor.

Distinctiveness Conflict Risk

Clear niche (Next.js 16+ Turbopack vs webpack bundling) with distinct, specific triggers; only minor overlap risk with generic Next.js or webpack build skills, fitting the 'mostly distinct' anchor rather than the minimal-conflict top anchor.
