Development
Set up self-hosted Inngest on macOS as a durable background task manager for AI agents. Interactive Q&A to match intent — from Docker one-liner to full k8s deployment with persistent state. Use when: 'set up inngest', 'background tasks', 'durable workflows', 'self-host inngest', 'event-driven functions', 'cron jobs', or any request for a local workflow engine.
Guides developers through running in-person, card-present sales and refunds through Payroc Cloud—the semi-integrated cloud-to-device API where a POS sends an instruction to the Payroc gateway and the gateway relays it to a physical payment device. Use this skill whenever the user mentions Payroc Cloud, “pay by cloud”, semi-integrated card-present payments, sending a sale/refund/signature to a terminal or card reader via the API, payment-instructions / refund-instructions / signature-instructions, polling an instruction, cloud device payments—even if they don't say “skill” explicitly. Covers the async submit → poll → follow-link → retrieve flow, idempotency, cancelling an in-progress instruction, referenced vs unreferenced refunds, reversals, signature capture, closed-loop reads, and finding a device serialNumber via GET /devices. Do NOT use this skill for card-not-present / e-commerce flows, for Hosted Fields, Hosted Payment Pages, or Payment Links (browser-based—separate skills), or for physically configuring or pairing a payment device (that is hardware setup, out of scope). If the user wants to set up or pair a device, say that is out of scope and that this skill picks up once a device serial number exists.
Adds multi-language support to Next.js websites with proper SEO configuration including hreflang tags, localized sitemaps, and language-specific content. Use when adding new languages, setting up i18n, optimizing for international SEO, or when user mentions localization, translation, multi-language, or specific languages like Japanese, Korean, Chinese.

Write and edit `.tsx` or `.jsx` for Kita Html instead of React. Use this whenever the user mentions Kita, KitaJS, `@kitajs/html`, `safe` attributes, `kita-html check`, `xss-scan`, `reply.html()`, `res.html()`, Suspense `rid`, async components that return HTML strings, or asks for JSX in a server-rendered templating context where JSX compiles to strings rather than a virtual DOM. Also use it when the project contains Kita config such as `jsxImportSource: "@kitajs/html"`, `@kitajs/html-cli` or `@kitajs/ts-html-plugin`, even if the user only says "TSX" or "JSX".
Refactor Kotlin code toward clearer, more idiomatic design without breaking Spring behavior, serialization, persistence, or public contracts. Use when Java-flavored Kotlin needs cleanup, domain modeling should become more expressive, or boilerplate should be reduced, but the refactoring must remain safe for proxies, Jackson, JPA, configuration binding, and existing tests
Action-oriented architecture for Laravel. Invokable classes that contain domain logic. Use when working with business logic, domain operations, or when user mentions actions, invokable classes, or needs to organize domain logic outside controllers.
An interactive course tutor for the AI Engineering from Scratch course. Reads LEARNING.md, finds the next lesson, teaches it section by section in the terminal, then quizzes you and records progress. Works in a cloned repository or entirely through raw.githubusercontent.com — no setup required. Trigger phrases: “下一课”, “教我”, “继续课程”, “我们来学习”, “继续学习”, or “next lesson”, “teach me”, “continue the course”, “let's learn”, “resume learning”.
Configure Litestar logging with `LoggingConfig`, `queue_listener`, exception logging policy, selective stack-trace suppression, standard logging, picologging, Structlog, and custom logging config subclasses. Use when establishing or refactoring application logging behavior, request-level logs, or production-safe error logging in Litestar. Do not use for metrics/tracing instrumentation or exception-response contract design.

Review a solution before approving it, like a GitHub changes tab: show a file tree of red and green pseudo-code for inline comments, then respond with Approve, Commented, or Rejected. Use when the user wants to see what would change, a git-like diff, or the PR as if it were ready.
Diagnose WeChat DevTools failures through the official CLI instead of relying only on GUI screenshots. Use when Codex needs to run `open`, `preview`, or related commands, discover the live service port, classify whether a failure is CLI-visible, host-side, or outside preview scope, and apply or suggest only safe repo-level fixes.
Recover a WeChat Mini Program repository after wrong-root import, DevTools template residue, stale compile conditions, or TypeScript-recognition drift. Use when Codex needs to restore the intended repo shape, remove generated clutter, or tell the user exactly what to fix inside DevTools.
Validate or design a WeChat Mini Program scaffold, repository layout, or TypeScript setup against official platform rules. Use when Codex needs to review `project.config.json`, `app.json`, `miniprogramRoot`, page or component file sets, or the initial repo skeleton before feature work begins.
Guides MongoDB users through implementing and optimizing Atlas Search (full-text), Vector Search (semantic), and Hybrid Search solutions. Use this skill when users need to build search functionality for text-based queries (autocomplete, fuzzy matching, faceted search), semantic similarity (embeddings, RAG applications), or combined approaches. Also use when users need text containment, substring matching ('contains', 'includes', 'appears in'), case-insensitive or multi-field text search, or filtering across many fields with variable combinations. Provides workflows for selecting the right search type, creating indexes, constructing queries, and optimizing performance using the MongoDB MCP server.
Handle files and binary data in n8n correctly. Use when working with files, images, PDFs, attachments, uploads or downloads, base64, vision/multimodal input, or when an AI agent needs a file as tool input or output — and whenever the user mentions $binary, binaryPropertyName, "read the PDF", "attach the file", "send the image", Merge losing binary, or a CDN for chat images. Covers the $binary vs $json split, reading/writing binary, keeping binary alive across transforms with Merge, the agent-tool binary boundary, and the CDN/URL requirement for chat surfaces.
Build reusable, composable n8n sub-workflows. Use when extracting shared logic, building anything multi-step or reused across workflows, or any workflow over ~10 nodes — and whenever the user mentions sub-workflows, Execute Workflow, reuse, shared/common logic, modular workflows, "Define Below" inputs, waitForSubWorkflow, mode each vs all, or exposing a workflow as an agent tool. Covers typed sub-workflow inputs, all-vs-each execution, verb-first naming for discovery, stateless vs stateful design, and splitting by input shape.

Use when the user asks to package a library for npm, fix consumer import or type-resolution errors, or check publish-readiness. Not for version bumps, changelogs, releases, or registry auth
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.
