Debugging index for Vue 3: maps common symptoms in reactivity, computed, watchers, components, props and emits, templates, forms and v-model, lifecycle, slots, TypeScript and SSR hydration to reference notes that explain the cause and the fix.

Covers how JSX in Vue differs from React JSX, such as class instead of className and JSX plugin config, for migrating React JSX to Vue or fixing attribute type errors. A brief skill that points to a single reference note.

For Vue 3 projects on the Options API (data(), methods, this): how to get TypeScript inference with defineComponent and type props, event handlers and computed values, plus gotchas like avoiding arrow functions in methods and lifecycle hooks and not sharing debounced state across instances.

Pinia best practices and gotchas for Vue apps: fixing the getActivePinia error, returning all state from setup stores, keeping reactivity when destructuring stores, calling store methods from templates, keeping ephemeral filters in the URL, and using Pinia in large apps.

Guides the agent in writing library-grade Vue composables whose inputs accept a plain value, ref or getter: choose MaybeRefOrGetter or MaybeRef depending on whether the input is read-only or writable, and normalize with toValue() and toRef() inside watchers. Requires Vue 3 or Nuxt 3+.

Default workflow for Vue work: standardizes on Vue 3, the Composition API and script setup with TypeScript, reads core references on reactivity, SFCs, data flow and composables, plans component boundaries first, loads topics like slots, transitions and performance only when needed, then self-checks.

Vue Router 4 best practices and gotchas: guards and lifecycle hooks not firing when only params change, no this in beforeRouteEnter, async calls and infinite redirect loops in guards, the deprecated next() callback, and cleaning up listeners after unmount.

Testing practices for Vue apps: Vitest and Vue Test Utils, black-box component tests, flushPromises for async code, helpers for testing composables, Pinia stores, async components and Teleport, avoiding snapshot-only tests, and Playwright for end-to-end testing.

Teaches agents to build, debug and review stateful AI agents with the Cloudflare Agents SDK: state sync, scheduled tasks, RPC, MCP servers, email and streaming chat, checking the latest official docs first. Maintained by Cloudflare.

Cloudflare's official overview skill: recommends platform products such as Workers, R2, D1, Durable Objects, Containers and AI for your needs, then loads the matching sub-skills and docs. The same repo has dedicated skills for Wrangler, the Agents SDK and more.

Cloudflare's official plugin with skills for Workers, Durable Objects, the Agents SDK, Wrangler, Sandbox and web performance audits, plus the Cloudflare API MCP for account data and up-to-date docs.

Pluggable natural-language linter that checks Markdown and plain text for wording, punctuation and terminology consistency like code, with auto-fix, and can also run as an MCP server. Rules are installed separately, mostly for Japanese and English; requires Node.js 20+.

MCP server built into the textlint proofreader: agents check Markdown, plain text and other documents against your rules for wording, punctuation and formatting issues and get auto-fixed text. Needs Node.js plus a .textlintrc and rule packages in your project; textlint has no default rules.

Microsoft's official skill collection: 170+ skills focused on Azure SDKs (Python, .NET, TypeScript, Java, Rust) and Microsoft Foundry development, plus plugins, custom agents and MCP configs. Microsoft recommends picking skills per project rather than installing them all.

Agent skills maintained by the Flutter team: layered architecture, responsive layouts, fixing layout overflows, declarative routing, internationalization, JSON serialization, and widget and integration tests. Works alongside the Dart MCP server.

Official plugin from the Dart and Flutter teams that installs Flutter skills and the Dart MCP server together, covering layered architecture, responsive layouts, layout error fixes, widget and integration tests, routing and internationalization. Requires the Dart/Flutter SDK locally.

Finance skills for US, Hong Kong and China A-share markets: news from 10+ sources, quotes and fundamentals, sentiment analysis, time-series forecasts, signal tracking, impact-chain diagrams and reports. Needs Python; some skills download PyTorch models. Not investment advice.

Standards-based command-line calendar that syncs iCloud and other CalDAV calendars via vdirsyncer, so agents can query your schedule and quickly add events; also has an interactive UI. Setting up vdirsyncer takes some technical effort; no Windows support.

Replaces arXiv preprint entries in your .bib file with the official published versions from DBLP and ACL Anthology, keeping citation keys, to tidy references before camera-ready. Overwrites the file by default, so preview with --dry-run. Mainly covers CS venues; needs Python 3.10+.

Measurement-first audits and optimization of web quality using Lighthouse, Chrome DevTools performance traces and CrUX data, covering Core Web Vitals, WCAG 2.2 accessibility, SEO and best practices, for any frontend framework. By Addy Osmani (not an official Google project).

Connects to your Supabase projects: manage schemas and migrations, run SQL, deploy Edge Functions, create development branches and generate TypeScript types. A remote server hosted by Supabase with OAuth sign-in.

Open-source, agent-friendly BI: define metrics and dashboards in YAML and SQL, and rill init generates project instructions and MCP config for Claude Code so agents can build business dashboards and answer questions in natural language. Local use is free; publishing to Rill Cloud needs an account.

Supabase's official general skill covering the database, Auth, Edge Functions, Realtime, Storage, vectors and queues, plus supabase-js/SSR integration, the CLI and MCP, migrations and RLS security checks, and it checks the latest docs and changelog before acting.

Postgres rules ranked by impact: query optimization, indexing, connection pooling, RLS security, schema design and lock troubleshooting, with wrong-vs-right SQL examples, applicable to any Postgres. Maintained by Supabase.
