Vite build tool configuration, plugin API, SSR, and Vite 8 Rolldown migration. Use when working with Vite projects, vite.config.ts, Vite plugins, or building libraries/SSR apps with Vite.

Use when working on Nuxt 4+ projects - provides server routes, file-based routing, middleware patterns, Nuxt-specific composables, and configuration with latest docs. Covers h3 v1 helpers (validation, WebSocket, SSE) and nitropack v2 patterns. Updated for Nuxt 4.3+.

Use when building styled UI with @nuxt/ui v4 components - create forms with validation, implement data tables with sorting, build modal dialogs and overlays, configure Tailwind Variants theming. Use vue skill for raw component patterns, reka-ui for headless primitives.

Extract clean markdown content from web pages using Defuddle CLI, removing clutter and navigation to save tokens. Use instead of WebFetch when the user provides a URL to read or analyze, for online documentation, articles, blog posts, or any standard web page. Do NOT use for URLs ending in .md — those are already markdown, use WebFetch directly.

Look up prior Claude Code sessions when context is lost or forgotten. Use when asked "what did we do before?", "what happened in the last session?", "I forgot what we were working on", "find what I told you about X", or any request to recall past conversation history, prior decisions, experiments, or outcomes. Searches raw JSONL transcripts from ~/.claude/projects/ via DuckDB index. Returns verbatim user messages and summarizes AI actions and sub-agent outcomes. Summaries cached at ~/.claude/kaizen/session-summaries/.

Create user-facing App Store release notes by collecting and summarizing all user-impacting changes since the last git tag (or a specified ref). Use when asked to generate a comprehensive release changelog, App Store "What's New" text, or release notes based on git history or tags.

Scaffold, build, and package SwiftPM-based macOS apps without an Xcode project. Use when you need a from-scratch macOS app layout, SwiftPM targets/resources, a custom .app bundle assembly script, or signing/notarization/appcast steps outside Xcode.

Diagnose Swift Concurrency issues, refactor callback-based code to async/await, and guide Swift 6 migration when working with tasks, actors, @MainActor, Sendable, data races, thread safety, or concurrency-related compiler and linter warnings.

Enforces the Airbnb iOS Swift Style Guide on Swift code. Use this skill any time the user wants to: review Swift code for style compliance, lint or audit an iOS codebase, apply Airbnb Swift conventions to new or existing code, understand why code violates Airbnb style rules, or get corrected rewrites of Swift snippets. Triggers on any request mentioning Swift code quality, iOS code review, Airbnb style, linting Swift files, or when the user pastes Swift code and asks for feedback, fixes, or a review. Also use when the user asks to "clean up" or "format" Swift code, or asks "is this good Swift?" — even if they don't mention Airbnb by name.

Swift Concurrency review and remediation for Swift 6.2+. Use when asked to review Swift Concurrency usage, improve concurrency compliance, or fix Swift concurrency compiler errors in a feature or file. Concrete actions include adding Sendable conformance, applying @MainActor annotations, resolving actor isolation warnings, fixing data race diagnostics, and migrating completion handlers to async/await.

Generate a deep, code-first project wiki and VitePress documentation site (DeepWiki-style) for a repository. Use when asked to create a complete wiki/manual for a new codebase, build a code-first documentation site, or generate a `codewiki/` folder with structured Markdown, diagrams, and navigation based on the source code (not existing docs).

Build, audit, and improve Claude Code skills through guided interview and generation. Use when user says "create a skill", "build a skill", "make a new skill", "write a skill", "improve this skill", "audit this skill", "review my skill", "skill from scratch", "turn this into a skill", or /skill-builder. Produces guide-compliant skill directories with SKILL.md, references, and scripts.

libutil - General utilities. countTokens and estimateTokens for GPT-style token counting. generateHash creates SHA256 hashes. generateUuid creates unique IDs findProjectRoot locates repository root. updateEnvFile modifies environment files. exec runs child processes. createBundler downloads code bundles. Use for token counting, hashing, and project utilities.
