Development
Generate production-grade UI using real component patterns and best practices from 60+ documented interface components. Use when the user asks to build web interfaces, pages, dashboards, forms, navigation, or any UI — ensures modern, minimal, SaaS-quality output grounded in design system conventions rather than generic AI patterns.
Give crewAI agents tools and MCP servers on crewai 1.15.x: custom BaseTool with args_schema and @tool, which crewai_tools names really exist, tool caching, max_usage_count, ToolFailure, Agent(mcps=[...]) strings and MCPServerStdio/HTTP/SSE forms, rewritten MCP tool names, MCPServerAdapter, timeouts, and what works on a hosted deployment. Use when writing or debugging a tool or MCP connection, when you see 'cannot import name BaseTool from crewai_tools', 'You are missing the mcp package', 'MCPConnectionError', 'Operation timed out after 30 seconds', 'reached its usage limit', 'Invalid MCP reference', 'Anthropic function name ... must start with a letter', an agent that never calls an MCP tool, mcps=[...] that yields no tools (for example an https:// string under akickoff or on CrewAI AMP), or a stdio MCP server that works locally but not after deploy.
Design, implement, debug, review, and optimize portable WebGPU applications and WGSL shaders. Use when building render or compute pipelines; GPU simulations, cellular automata, particles, image processing, feedback effects, or data-parallel workloads; defining buffers, textures, bind groups, and host-shareable layouts; handling canvas sizing, optional features, errors, device loss, readback, and cleanup; or diagnosing validation, correctness, compatibility, and performance problems.
When the user wants a comprehensive technical analysis of a codebase or project. Also use when the user mentions 'analyze this codebase,' 'technical overview,' 'document this architecture,' 'what does this codebase do,' 'summarize this repo,' 'code audit,' 'architecture review,' 'codebase walkthrough,' or 'analyze this project.' Performs a multi-phase analysis covering architecture, code quality, testing, and infrastructure, producing a detailed markdown report targeting engineers. For quick code searches or single-file reviews, see standard editor tools.
Generate React Native Reanimated animation code for React Native apps. Use when user asks to create, implement, or add animations in React Native — including transitions, gestures, scroll-linked effects, layout animations, layout transitions, entering/exiting animations, CSS animations, CSS transitions, shared element transitions, color animations, parallax, fade, slide, scale, spring, timing, decay, keyframes, worklets, accordion, bottom sheet, flip card, collapsing header, or any motion effect using react-native-reanimated. Also use for integrating react-native-gesture-handler with Reanimated, understanding worklets, animating between screens, testing animations with Jest, or checking which properties are animatable.
Use this skill when drawing shapes and graphics in Phaser 4. Covers the Graphics game object, lines, rectangles, circles, arcs, polygons, gradients, fill, stroke, and generated textures. Triggers on: Graphics, draw shape, fillRect, lineStyle, polygon, arc.
Use this skill to diagnose and resolve what blocks a DevOps Center promotion of a work item's feature branch: Git merge conflicts and deployment failures. DevOps Center is Git-backed, so overlapping metadata changes surface as merge conflicts against the target stage branch, resolved with git (detect, resolve markers, commit, push). Deploy failures often cite a missing dependency a full promotion can fix when the component already exists on the branch. TRIGGER when the user wants to check a work item for conflicts before promoting, resolve merge conflicts or leftover conflict markers in metadata files (.xml, .object-meta.xml, .cls), reconcile a feature branch with its target stage branch, or diagnose why a DevOps Center promotion or deployment failed and whether a full promotion or a missing-dependency fix will resolve it. DO NOT TRIGGER for running the promotion itself (use dx-devops-promote), creating or updating work items (use dx-devops-work-item-manage), or deploying metadata directly to an org.
Query filters or item selection to bulk query and update field values (Status/Priority/Size etc.) of project items. Supports SINGLE_SELECT/TEXT/NUMBER/DATE field types. Used for "change Status to In Progress", "bulk update priority", "set all Todo to In Progress", etc.
Install, load, and unload SAS packages with the SAS Packages Framework (SPF) and the SASPAC archive — package fileref rules, %installPackage / %loadPackage / %helpPackage / %unloadPackage, and version pinning. Use when installing a package such as sasjscore or debugging an installation that reports rc=20006 or a missing package zip
Develops high-performance Magento 2 storefronts using the Hyvä theme framework. Use when working with Hyvä themes, Alpine.js, Tailwind CSS, or modern frontend development. Masters Alpine.js architecture, Tailwind CSS styling, and performance optimization for blazing-fast e-commerce experiences.
Use this when installing, running, or configuring the Adobe AEM CLI (@adobe/aem-cli, formerly the helix-cli npm package; commands `aem up`, `aem import`, `aem content`), when `aem up` fails (port conflicts, cert errors, proxy 404s, pipeline vs. local-file confusion), or when migrating from the old helix-cli package. Covers installation, the local Edge Delivery dev server, .env / AEM_* configuration, HTTPS/TLS, proxy and certificate trust, content sync with da.live, and troubleshooting. For da.live content-format rules or the DA Source API contract use da-content; for writing EDS block code use content-driven-development.
Current crewai 1.15.x API versus the 0.x API that coding assistants remember: imports, Agent/Task/Crew parameters and defaults, kickoff variants, CrewOutput fields, LLM model strings and provider extras, structured output (output_pydantic, response_model, response_format), guardrails, unified Memory, knowledge embedders, the `crewai create crew` wizard vs --classic, reset-memories flags, and removed features. Use when writing, reviewing, or debugging any crewai code, before trusting remembered crewai syntax, or when a user pastes errors like `cannot import name 'BaseTool' from 'crewai_tools'`, `cannot import name 'persist'`, `ShortTermMemory`, `Anthropic native provider not available`, `LiteLLM fallback package is not installed`, `got an unexpected keyword argument 'response_format'`, `OPENAI_API_KEY is required`, `If return type is annotated, it must be Tuple[bool, Any]`, or `result.pydantic is None`
Use when working with iOS/macOS Keychain Services (SecItem queries, kSecClass, OSStatus errors), biometric authentication (LAContext, Face ID, Touch ID), CryptoKit (AES-GCM, ChaChaPoly, ECDSA, ECDH, HPKE, ML-KEM), Secure Enclave, secure credential storage (OAuth tokens, API keys), certificate pinning (SecTrust, SPKI), keychain sharing across apps/extensions, migrating secrets from UserDefaults or plists, or OWASP MASVS/MASTG mobile compliance on Apple platforms
Generate enterprise-grade documentation for NetSuite SDF projects. Analyze scripts, object XML files, `manifest.xml`, and SuiteQL queries to produce README.md, architecture diagrams (Mermaid/ASCII), deployment guides, and troubleshooting tables. Can integrate with post-deployment documentation workflows when automation (for example hooks) is available.
Provides the complete, verified grep scan command library for auditing React codebases before a React 18.3.1 or React 19 upgrade. Use this skill whenever running a migration audit—for both the react18-auditor and react19-auditor agents. Contains every grep pattern needed to find deprecated APIs, removed APIs, unsafe lifecycle methods, batching vulnerabilities, test file issues, dependency conflicts, and React 19 specific removals. Always use this skill when writing audit scan commands—do not rely on memory for grep syntax, especially for the multi-line async setState patterns which require context flags.
Compiler sanitizer skill for runtime bug detection in C/C++. Use when enabling and interpreting AddressSanitizer (ASan), UndefinedBehaviorSanitizer (UBSan), ThreadSanitizer (TSan), MemorySanitizer (MSan), or LeakSanitizer (LSan) with GCC or Clang. Activates on queries about sanitizer flags, sanitizer reports, ASAN_OPTIONS, memory errors, data races, undefined behaviour, uninitialised reads, or choosing which sanitizer to use for a given bug class.
Writes failing tests first for test-driven development and hands off a strict implementation contract that requires agents to make those tests pass without weakening the tests. Use when users ask for test-first workflows, RED/GREEN cycles, or behavior-gating tasks with automated tests.
Use when generating HTML for Adobe Document Authoring (DA, da.live) upload, uploading media binaries to DA, publishing to aem.live, or driving the DA admin API (auth, source PUT, preview/publish). Covers block HTML format (canonical div-class form and accepted table alternate), section structure, page and section metadata, icons, links, images, default content, document skeleton constraints, block cell content normalization, the DA Source API contract, IMS auth, media storage, supported formats, Media Bus vs Content Bus delivery, and silent-failure rules that corrupt content.
Summarizes project progress by status, priority and size, and generates a report. A read-only skill that outputs the completion rate and a breakdown of outstanding items by priority in table format. Used when the user says 「進捗を見せて」「プロジェクトレポート」「完了率は？」「ステータス別の件数」.
Python software engineering guidelines from real PR review patterns. This skill should be used when writing, reviewing, or refactoring Python code — especially dataclasses, service interfaces, error handling, and type annotations. Triggers on tasks involving Python modules, API design, data modeling, type safety, exception handling, or refactoring for maintainability. For asyncio and concurrency guidance, see the python-async-best-practices skill.
Use the mcpc CLI to work with MCP (Model Context Protocol) servers from the shell — connect to a server as a persistent session, then list and call tools, read resources, get prompts, and run async tasks. Use --json for scripting and code mode. Reach for this whenever interacting with MCP servers, calling MCP tools, or accessing MCP resources programmatically.
Calling a crew or flow deployed on CrewAI AMP over HTTP: the bearer token and deployment URL, GET /inputs, POST /kickoff with the {\"inputs\": {...}} body, which input keys are required ({placeholder} tokens), polling GET /status/{kickoff_id} with a deadline and backoff, terminal states and where the result lives, webhooks, POST /resume, slow first calls, and writing crews that stay correct when they are kicked off repeatedly or concurrently. Use when writing a client, script, backend or frontend that calls a deployed crew, when a kickoff returns 422 \"Missing inputs: ...\", when a status poll never ends, says \"NOT FOUND\" or the result field is empty, when /resume returns 422 for executionId, when a run's prompt shows another run's data, or when the user pastes a kickoff_id, a /kickoff curl, or 'Template variable ... not found in inputs dictionary'
Clone a game template from the gallery as a starting point. Use when the user says "use a template", "start from a template", "clone flappy-bird", "use the platformer template", or wants to quickly bootstrap a game from an existing example. Do NOT use for creating a game from scratch (use viral-game for one-shot builds or make-game for milestone-driven projects).
Apply when building, customizing, or deploying extensions for VTEX Sales App. Covers the complete 7-step workflow from prerequisite checks through code generation to deployment, including extension points (cart, PDP, menu), React hooks (useCart, usePDP, useCartItem, useCurrentUser, useExtension), TypeScript types, secure API integration patterns, and API documentation ingestion (OpenAPI, URLs, or inline specs) to generate typed integrations.
Monitor manifests e arquivos estruturais para criar ou atualizar .specsfy/STACK.md de forma aditiva. Use quando o monitor de contexto apontar stack pendente; quando framework, linguagem, runtime, pacote estrutural, ferramenta de teste ou persistência mudar; quando a documentação técnica estiver incompleta; ou após adicionar Laravel, Next.js, Astro ou dependências relevantes. Preserva conteúdo humano existente.
Use when writing, reviewing, or refactoring code for maintainability and readability. Triggers on code reviews, naming discussions, function design, error handling, and test writing. Based on Robert C. Martin's Clean Code handbook with modern corrections.
Official Framer Motion skill for React integration — AnimatePresence, motion components, useAnimation, layout animations. Use when building React animations, using AnimatePresence, Framer Motion with Next.js, or when asking about Framer Motion React patterns, cleanup, or SSR.
Define typed API endpoints in Encore.ts using `api(...)` from `encore.dev/api`. Covers typed request/response interfaces, path/query/header/cookie params, request validation, and `APIError`. For raw endpoints (`api.raw()`) and inbound webhooks, use `encore-webhook` instead.
Best practices for building Nuxt 3 and Vue 3 applications with TypeScript, the Composition API, and Tailwind CSS. Use when structuring Nuxt/Vue projects, writing composables, typing components and props, wiring up server routes and plugins, or optimizing Nuxt builds and Web Vitals.
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.
