Development
Guides feature development for full-stack applications with an architecture focus. Covers Next.js App Router patterns, NestJS backend services, database models, data workflows, and seamless integration. Use when adding features, refactoring existing code, or planning major changes
Build and iterate on an Apollo Connectors subgraph for a GraphOS supergraph from a REST API, with or without an OpenAPI or Swagger spec, in a dedicated git workspace that records what the API offers, the user's operation and field selection, every design decision, and the evidence each verification layer produced. Use whenever the user wants to wrap a REST API as a GraphQL subgraph for their supergraph, add or remove operations or fields from an existing connector subgraph, refresh one against a new spec, or record live API traffic as test fixtures, even if they do not say "connector", "subgraph" or "Apollo"
Expert guidance for the Identity vs User split and tenant memberships in Rails. Use when adding users, workspaces, accounts, memberships, roles, join codes, invites, Current.identity, Current.user, or connecting magic-link auth to a tenant. Complements magic-link-auth and activerecord-tenanted. Not Nebula workspace members.
Guide to creating and building high-quality MCP servers that let LLMs interact with external services through well-designed tools. Use when the user wants to build, develop, or implement an MCP server integrating external APIs or services in Python (FastMCP) or Node/TypeScript (MCP SDK). To only install/configure an existing MCP server (e.g. Jira), use setup instead.
Create custom external web service APIs for Moodle LMS. Use when implementing web services for course management, user tracking, quiz operations, or custom plugin functionality. Covers parameter validation, database operations, error handling, service registration, and Moodle coding standards.
MSW (Mock Service Worker) v2 and v3 best practices, patterns, and API guidance for API mocking in JavaScript/TypeScript tests and development. Covers handler design, server setup, response construction, testing patterns, GraphQL, and v1-to-v2 and v2-to-v3 migration. Baseline: msw ^3.0.0. Triggers on: msw imports, http.get, http.post, HttpResponse, setupServer, setupWorker, graphql.query, sse, ws.link, or mentions of “msw”, “mock service worker”, “api mocking”, or “msw v3”.
Use the public `orca` CLI to operate Orca-managed worktrees, folder contexts, terminals, repos, automations, artifacts, worktree comments, and the browser embedded inside the Orca app. Use when the user says "$orca-cli", "use orca cli", "Orca worktree", "child worktree", "cardStatus", "spawn codex/claude in a worktree", "read/wait/send Orca terminal", "terminal send", "full handoff", "handover", "give this to another agent", "another worktree", "Orca browser", "orca artifacts", "share HTML/Markdown", "public artifact link", or "control the browser inside Orca". Prefer this over raw `git worktree`, ad hoc PTYs, Playwright, or Computer Use when the task touches Orca-managed state. Use Computer Use for browser windows, webviews, or desktop UI outside Orca's embedded browser.
Expert guidance for delivering signed HTTP webhooks from a Rails app to customer URLs. Use when adding webhooks, HMAC signatures, SSRF protection, webhook deliveries, auto-disable on failure, or posting events to Slack/customer endpoints. Covers Fizzy and Herald delivery. Not inbound Stripe/GitHub webhooks.
Mở rộng một draft SPEC ĐÃ ĐƯỢC DUYỆT thành kế hoạch thi hành được — file `DDMMYY-<tên>-PLAN.md` mà một agent KHÔNG có context nào (CLI rẻ chạy headless, không hỏi lại được) vẫn làm đúng: đường dẫn file chính xác, khối Interfaces (Consumes/Produces) khai chữ ký cho task hàng xóm, ràng buộc bao trùm chép nguyên văn, và từng bước 2-5 phút kiểu TDD có code thật + lệnh chạy + output mong đợi. Gọi SAU `/propose` và SAU khi user duyệt ở cổng, TRƯỚC khi dispatch task cho agent. Trigger - "viết plan", "mở rộng proposal thành plan", "plan thi hành", "chuẩn bị brief cho agent", "/plan". KHÔNG dùng để thiết kế hay để hỏi yêu cầu (đó là `/propose`), KHÔNG dùng khi chưa có SPEC duyệt.
Use for Roblox persistent data and cross-server state design: choosing between DataStoreService, OrderedDataStore, MemoryStoreService, and MessagingService; designing save and load flows, schema shape, versioning, metadata, retries, quotas, observability, and concurrency-safe coordination across servers.
Expert-level Rust development with ownership, lifetimes, async, error handling, and production-grade patterns. Use when the user mentions systems programming, memory safety, concurrency, or Cargo, or when the task involves Ownership and Borrowing, Type System, Async Programming, or Web Development.
Interactive onboarding wizard to set up Polar payment integration from scratch. Use this skill when: (1) the user wants to “set up Polar” or “integrate Polar” in their project; (2) the user is starting fresh with Polar and needs guided setup; (3) the user asks “how do I get started with Polar”; (4) the user wants to add payments, subscriptions, or checkout to their app using Polar; (5) the user needs help creating their first Polar product and checkout. This skill walks through MCP installation, authentication, product creation, and generates framework-specific integration code
Apply when writing or reviewing a spec, requirements, acceptance criteria, user stories, or tickets, before any code exists. Two passes: an edge probe over a closed taxonomy of data-shape boundaries, and a prohibition probe for what the feature must never silently become. Every raised item is resolved, dismissed with a reason, or carried as an explicit gap.
Create and configure Twilio Messaging Services for production messaging. Covers sender pools, geo-match, sticky sender, message scheduling, compliance toolkit, SMS pumping protection, link shortening, and intelligent alerts. Use this skill when setting up production-ready messaging infrastructure.
Convert a vibe-coded webpage into a page built entirely from YOUR design system. Takes an AI-generated artifact, a landing page, a prototype, or any page carrying bespoke CSS, works out what each region is trying to do, and rebuilds it from real components and real tokens. Use when the user says "rebuild this with our design system", "convert this page", "make this use our components", "de-vibe this", "kill the vibes", "turn this artifact into something real", pastes an HTML file or a URL and names their design system, or wants a before/after demo of a page moving onto the system. Builds a one-time profile of the design system's runtime and component vocabulary, then converts against it. Companion to ds-adoption-plan, which plans a whole product's migration; this one converts a single page and hands back working code.
C/C++/CAPL best practices for automotive embedded systems. This skill should be used when writing, reviewing, or refactoring embedded C/C++ code or CAPL scripts targeting automotive ECUs, following MISRA, AUTOSAR, ISO 26262, and ISO 21434 guidelines. Triggers on tasks involving embedded firmware, CAN/CAN FD/LIN/Ethernet communication, TCP/UDP/DoIP/SOME-IP protocols, RTOS programming, safety-critical code, cybersecurity, diagnostics (UDS), CAPL test automation, or calibration toolchain integration.
Use when structuring app entry points, managing authentication flows, switching root views, handling scene lifecycle, or asking 'how do I structure my @main', 'where does auth state live', 'how do I prevent screen flicker on launch', 'when should I modularize' - app-level composition patterns for iOS 26+
Use when asking 'where should I store this data', 'should I use SwiftData or files', 'CloudKit vs iCloud Drive', 'Documents vs Caches', 'local or cloud storage', 'how do I sync data', 'where do app files go' - comprehensive decision framework for all iOS storage options
Expert knowledge for Azure Maps development including best practices, decision making, architecture & design patterns, limits & quotas, security, configuration, and integrations & coding patterns. Use when using Azure Maps Web/REST SDKs, geocoding, routing, traffic, weather tiles, or Power BI visual integrations, and other Azure Maps related development tasks. Not for Azure AI Search (use azure-cognitive-search), Azure IoT (use azure-iot), Azure IoT Central (use azure-iot-central), Azure IoT Edge (use azure-iot-edge).
Fix a confirmed bug at its root cause with the smallest correct change only—reproduce it before touching code: write a failing reproducer, diagnose the first broken assumption in the data flow, load the matching framework reference and category playbook, apply the minimal fix, then verify the reproducer passes and run the regression scope. Never write fix code without a reproducer (or a documented reason one is impossible), patch the symptom while the root cause remains, or weaken a test to pass. Use when the user says “fix this bug”, “fix the findings”, “/bugfix”, or asks to repair a confirmed defect
Generates OutSystems Developer Cloud (ODC) build action JSON files that configure Capacitor mobile plugin builds for Android and iOS. Produces correct JSON with platform-specific actions, input variables, and conditional logic. Use when a developer says "create a build action for my ODC plugin", "generate a buildAction.json file", "set up Gradle or plist build actions for a Capacitor or Cordova plugin", "configure AndroidManifest for ODC build", or "scaffold ODC native build configuration". If the target platform is ambiguous, still generate and note that build actions only apply to ODC — they have no effect in standalone Capacitor apps. Do not use when the developer explicitly mentions Cordova apps, O11, Cordova extensibility configurations, MABS versions prior to 12, or uploading and registering the JSON in ODC Studio.
Conventional Commits specification. Covers commit structure, types, breaking changes. Use when writing structured commit messages, configuring automated changelog generation, or applying semantic versioning conventions. Keywords: feat, fix, BREAKING CHANGE, Conventional Commits.
Build elaborate multi-component claude.ai HTML artifacts with React, TypeScript, Vite, Tailwind CSS, and shadcn/ui, then bundle them into a single HTML file. This is the artifacts-builder skill from ComposioHQ's awesome-claude-skills collection, a copy of Anthropic's web-artifacts-builder. It does not integrate Composio tools.
Scaffold, build, package, and install a custom visualization into Splunk using the dashboard-studio-extension framework. Use when the user wants to create a new custom viz, add a visualization to an existing project, or migrate a legacy custom viz.
Implement customer email in a Customware-generated React Router and Hono app, including durable Postmark inbound receipt and direct Postmark outbound sending. Use when a Builder task names the customware-email skill, provides a Postmark virtual inbound address, or asks to add customer-facing email to an existing Customware app.
Build serverless TypeScript functions on Zavu Cloud — declare agents + tools in code with defineAgent / defineTool, deploy with `npx zavudev deploy`, debug with `npx zavudev agents executions`. Use this skill whenever the user wants code-driven AI agents, custom tool handlers, or event-driven business logic.
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
