Conciseness

The ~40-line body is pure signal — a one-line goal ('Migrate a Nuxt component from Nuxt 2 / Options API to Nuxt 3 `<script setup lang="ts">`'), a terse analysis checklist, and a 14-row conversion mapping with zero padding. It assumes Claude's competence (no explanation of ref(), script setup, or auto-imports), matching anchor 5; nothing can be trimmed.

Actionability

The conversion table is copy-paste-ready ('props -> defineProps<T>()', '$axios -> $fetch') and validation gives executable commands ('nuxi typecheck', 'npx vitest run --passWithNoTests'). It falls short of anchor 5 because steps like 'Apply composition pattern if there is prop drilling', 'Decompose if > 200 lines', and 'Map who imports this component' give direction without the specific command or example.

Workflow Clarity

A clear 6-step sequence (read architecture docs, analyze, convert, refactor, decompose, validate) ends in explicit validation commands. It misses anchor 5 because there is no feedback loop — nothing instructs what to do when 'nuxi typecheck' fails — leaving error recovery implicit.

Progressive Disclosure

The skill is under 50 lines, single-purpose, has no bundle files, and is organized under a clear '## Steps' section; the only external pointer ('docs/ARCHITECTURE.md section 5') is clearly signaled twice and one level deep. Per the simple-skill guideline this earns anchor 5; nothing that belongs in a separate file is inlined.

Specificity

The description names the domain ('a component needs migration to the target architecture or framework version') but states no concrete actions — the actual conversion work (Nuxt 2 Options API to Nuxt 3 script setup) is entirely absent. It matches anchor 2 ('names the domain but actions are minimal or generic'), not anchor 3, which requires 1-2 concrete actions.

Completeness

Only the 'when' half is present ('Use when a component needs migration...') with no 'what' — the description never states that it converts components to Nuxt 3 '<script setup lang="ts">'. This is an exact match to anchor 2 ('only when is present without what'); it cannot be 3 because a clear 'what' is entirely missing.

Trigger Term Quality

'component', 'migration', and 'framework version' are relevant keywords, but the natural phrases a user would say for this task — 'Nuxt 3', 'Nuxt 2', 'Vue', 'Options API', 'upgrade', 'port' — are all missing. This matches anchor 3 ('some relevant keywords but missing common variations or synonyms'); it sits above anchor 2 because 'migration' and 'component' are genuinely natural terms rather than generic filler.

Distinctiveness Conflict Risk

'a component needs migration' is somewhat specific, but 'target architecture or framework version' names no framework, so a React, Vue, or Angular migration request would match this trigger equally well. This matches anchor 3 ('somewhat specific but could still overlap with similar skills'); it is above anchor 2 because component migration is a narrower niche than 'document files'.
