sc-js

JS code quality auditor. Detects the project stack via sniff (01-scan), loads the applicable JS knowledge pivots from the plugin, and delegates a structured code review to aidd-dev:reviewer using the pivots as acceptance criteria. Use when the user asks to: audit JS code, check JS best practices, review code quality, check my JS, audit Vue components, check Pinia usage, review code against JS standards, or invokes /sc-js:audit. Does not install any files to .claude/rules/.

Réceptacle du pivot design pour JavaScript/TypeScript. Reçoit le spec du contrat de pivot (plugins/design/references/sc-pivot-contract.md) émis par design:enforce ou design:diffuse, et réalise nativement : (1) enforce → règle ESLint ou script Node.js validant les classes et tokens CSS, dérivant strictement du spec + wiring pre-commit ; (2) diffuse → élément neutre rendu en composant Vue 3 SFC ou React idiomatique. Jamais invoqué directement — uniquement appelé via le pivot de design:enforce/04-pivot ou design:diffuse/03-pivot.

Analyzes a JavaScript/TypeScript codebase for idiomatic JS gaps, Vue/Nuxt anti-patterns, and maintainability issues, then produces a prioritized improvement plan. Covers proper async/await usage, TypeScript type coverage, Vue Composition API adoption, Pinia state patterns, component decomposition, and framework idioms (Nuxt, Vue SPA, Alpine, Vite). Use when the user says "how can I improve this", "find anti-patterns", "code quality", "refactoring suggestions", "how to better structure this", "is this good JS/TS". Do NOT use for performance (web-optimize), data layer (data-optimize), version migrations (legacy), or line-by-line code review (aidd-dev:05-review).

Scans JavaScript/TypeScript code for outdated patterns and deprecated APIs, then proposes a migration plan. Handles ES5 remnants (var, callbacks, prototype patterns), CommonJS→ESM migration, Vue 2→3 (Options API → Composition API, Vuex → Pinia), Svelte 4→5 (runes: $state/$derived/$effect/$props, slots→snippets, on: directives → DOM attributes), SvelteKit 1→2 (redirect throws, $app/state), TypeScript strictness evolution, and framework version migrations (Nuxt 2→3). Use when the user says "modernize", "upgrade to Vue 3", "migrate to ESM", "this uses old JS", "remove Vuex", "this is Vue 2 code", "migrate to runes", "upgrade to Svelte 5", or when deprecated patterns appear in the codebase. Do NOT use for dependency management (npm/pnpm), performance optimization (web-optimize), or general refactoring unrelated to version compatibility.

JS stack detector for JavaScript projects. Reads package.json to detect the runtime (web vs desktop), framework (Nuxt, Vue SPA, Vite, Alpine, Astro, 11ty), ORMs (Prisma, Drizzle, TypeORM, Mongoose, GraphQL, tRPC), and capabilities in use (state management, icons, code splitting, SSR, etc.). Emits a pivot manifeste — the list of applicable JS knowledge references in the plugin — for use by /sc-js:audit. Installs perf pivots (for web-optimize) and data pivots (for data-optimize) to .claude/rules/07-quality/. Does not install capability rules to .claude/rules/ — those are loaded on demand at audit time. Run /sc-js:sniff clean to migrate from sc-js 0.3.0. Prefer sniff over setup on already-configured projects.
