Development
Apple's open-source `container` CLI to build, run, and manage OCI/Linux containers as lightweight per-container VMs on Apple-silicon macOS — no Docker daemon required. Use when the user mentions the `container` CLI, "apple container", running or building containers on macOS without Docker/Podman, `container run`, `container build`, `container images`, `container system start`, pushing/pulling images to a registry, or container networking on macOS. This is Apple's `container` tool specifically (repo `apple/container`), NOT Docker, Podman, containerd, nerdctl, or Kubernetes — the CLI is Docker-like but is a different tool.
CloudBase WeChat Mini Program native authentication guide. This skill should be used when users need mini program identity handling, OPENID/UNIONID access, or wx.cloud auth behavior in projects where login is native and automatic.
Axios - promise-based HTTP client for browser and Node.js USE WHEN: user mentions "Axios", "HTTP requests", "API calls", "interceptors", "Axios instance", asks about "how to make HTTP calls", "configure Axios", "add auth header", "handle HTTP errors" DO NOT USE FOR: Fetch API - use `http-clients` instead; ky/ofetch - use `http-clients` instead; GraphQL clients - use `graphql-codegen` instead; tRPC - use `trpc` instead
Check custom SCAPI endpoint registration status using the b2c CLI. Use this skill whenever the user needs to verify that their custom API endpoints are registered and working, debug 404 or "endpoint not found" errors on custom APIs, or list custom API endpoints and their deployment status — even if they just say "my custom API returns 404" or "is my endpoint deployed".
Upgrades a Capacitor app from v8 to v9 (prerelease, installed with @next until GA). Covers preflight (Node 24, Xcode 27, Android Studio 2026.1.1, UIScene adoption from 8.5), `npx cap migrate`, and the manual checklist - iOS 16 target, @UIApplicationMain to @main, removed CAPBridge APIs, AGP 9.2.1, Gradle 9.5.1, SDK 37/minSdk 26, gradle.properties cleanup, built-in Kotlin, jcenter removal, core-ktx, proguard-android.txt rename, optional Cordova runtime, `cap run --url`, push `alert` removal, splash fade default. Use for "upgrade to Capacitor 9", errors like "'@UIApplicationMain' is deprecated", "Could not find method jcenter()", getDefaultProguardFile('proguard-android.txt') failures, duplicate Kotlin plugin, duplicate class core-ktx, "unknown option '-l'". Do not use for 8.4 to 8.5 UIScene only (use capacitor-uiscene-migration), plugin libraries (use capacitor-plugin-upgrade-v8-to-v9), or older majors.
Clean-code engineering standards for writing, refactoring, and reviewing code in any programming language. Use this whenever the user asks to write clean code, follow clean-code principles, refactor for clarity, improve naming, reduce complexity or duplication, separate concerns, tighten error handling, work test-first or do TDD, or otherwise raise code quality, readability, and maintainability. Apply these rules by default when producing or changing code for a quality-conscious user.
Craft CMS 5 PHP coding standards and conventions. ALWAYS load when writing, editing, reviewing, or discussing any PHP in a Craft plugin or module — even small edits. Also when running ECS, PHPStan, or scaffolding with ddev craft make. Covers: PHPDoc blocks (@author, @since, @throws chains), section headers (=========), class organization, naming conventions (services, queue jobs, records, events, enums), defineRules() and validation, beforePrepare() and addSelect(), MemoizableArray, DateTimeHelper vs Carbon, strict_types/declare(strict_types=1), short nullable notation (?string), typed properties, void returns, control flow (early returns, match over switch), CP Twig template conventions, form macros, translations (Craft::t), ECS/PHPStan config, scaffolding commands, and the verification checklist.
Push the current branch and create a pull request on GitHub. Derives the title and description from any JIRA ticket referenced by the branch, and references every issue (JIRA, GitHub, etc.) the PR actually fixes — never related items. Draft by default, use --no-draft for a ready PR.
Use this skill when authoring or extending an Unreal Engine toolset, a class of static, AI-callable functions registered with `ToolsetRegistry` and exposed through the unreal-mcp server. Trigger when the user wants to add, expose, or register a new tool method, create a new toolset, or extend an existing one such as `BlueprintTools`, `StaticMeshTools`, `ObjectTools`, `LevelTools`, or `MaterialTools`. Concrete triggers: 'add a tool to X', 'expose this via MCP', 'register a function so Claude/the agent can call it', 'wire this into the toolset registry', 'create a new toolset for Y', 'add a Python toolset', 'make this AI-callable'; adding a `static` method to a `*Tools.cpp/.h/.py` file; editing files under a `Toolsets/` folder; designing tool parameters, return types, or struct schemas for a toolset. SKIP for: invoking existing tools at runtime (use unreal-mcp instead), authoring an Agent Skill (use unreal-skill), generic refactors that happen to touch a toolset file but don't add or redesign a tool, or unrelated uses of the word 'toolset'.
CuTe Python DSL API reference and implementation patterns for NVIDIA GPU kernel programming. Provides execution model, core API table, key constraints, common patterns, and documentation index. Use when: (1) writing or modifying CuTe DSL kernel code, (2) looking up CuTe DSL API syntax, (3) implementing attention/GEMM/MLA patterns in CuTe DSL, (4) understanding CuTe DSL execution model and compilation pipeline, (5) checking what CuTe DSL can and cannot do.
ALWAYS use when touching ANY DayZ file (.c, config.cpp, mod.cpp, .layout, types.xml) or discussing DayZ modding, Enforce Script, or the Enfusion engine. Activate even if the user does not explicitly mention DayZ — if the code imports DayZ classes (PlayerBase, EntityAI, ItemBase, MissionServer), uses DayZ APIs (GetGame(), Class.CastTo(), ScriptRPC), or references DayZ patterns (modded class, CfgPatches, requiredAddons), this skill MUST be loaded. Covers 40+ critical gotchas, complete engine API across 20+ systems, mod architecture, RPC networking, GUI widgets, performance optimization, and professional patterns from COT, VPP, and Expansion mods. Without this skill, the agent WILL produce broken Enforce Script code.
Creates a Technical Specification from an existing PRD: deep project analysis, technical research (documentation MCP when available, otherwise Web Search), clarifying questions, then the architecture and implementation guidance. Use to create a tech spec or define architecture for a feature with a PRD. Not for PRDs, task breakdowns or code implementation.
Expert in documentation structure, cohesion, flow, audience targeting, and information architecture. Use PROACTIVELY for documentation quality issues, content organization, duplication, navigation problems, or readability concerns. Detects documentation anti-patterns and optimizes for user experience.
Scaffold a native-looking, effective Electron app with best practices baked in. Creates a production-ready Electron application with security hardening, modern tooling, proper IPC patterns, auto-updates, native UI elements, and optimal build configuration. Use this skill when users want to start a new Electron project or modernize an existing one.
Git-based engineering retrospective analyzing commits, PRs, and velocity over configurable windows with monorepo path scoping. Triggers on: "retrospective", "sprint retro", "weekly review", "what did we ship", "engineering retro", "dev summary", "commit analysis".
Design, tune, or review EF Core data access with proper modeling, migrations, query translation, performance, and lifetime management for modern .NET applications. USE FOR: DbContext, migrations, model configuration, EF queries, tracking, loading, performance, transactions, and EF6 migration decisions. DO NOT USE FOR: unrelated stacks; generic tasks that do not need this specific guidance. INVOKES: inspect the repository context, edit targeted files, and run relevant build, test, lint, or validation commands when changes are made.
Designs neural network architectures that respect validated symmetry groups, recommending architecture families (G-CNN, steerable CNN, e3nn), layer patterns, and implementation libraries. Use when you have validated symmetry groups and need equivariant architecture design, or when user mentions equivariant layers, G-CNN, e3nn, steerable networks, or building symmetry into a model.
Use when you have an approved implementation plan document and need to execute it step by step. Triggers on /execute command, when transitioning from planning with an approved plan, or when resuming execution of a partially completed plan. Provides batch-based execution with TDD, checkpoint reviews, and verification gates.
Provides comprehensive guidance for Express.js framework including routing, middleware, request handling, templating, and API development. Use when the user asks about Express, needs to create Express applications, set up routes, implement middleware, or build REST APIs.
Banuba Face AR SDK skill for three use cases: sales, developer documentation, and integration workflows. Use when working on anything Face AR: capability and compliance questions (sales), documentation lookup, CV concepts, and troubleshooting (dev), and building Web integrations such as AR masks, face filters, beautification, virtual background, and AR Cloud (integration). Trigger with "Face AR", "AR mask", "face filter", "virtual background", "AR makeup", "beautification", "face landmarks", "AR Cloud", "can the SDK", "how does", "explain", "add", "set up", "integrate", "build". Web, Android, iOS, Desktop (C++), Flutter and React Native have full code generation support. macOS gets the GitHub sample + code assistance. Unity gets the sample link only. For Video/Photo Editor SDK use build-video-editor, build-photo-editor, or explain-video-editor-photo-editor-docs.
Build MCP servers in Python with FastMCP framework to expose tools, resources, and prompts to LLMs. Supports storage backends (memory/disk/Redis), middleware, OAuth Proxy, OpenAPI integration, and FastMCP Cloud deployment. Use when: creating MCP servers, defining tools or resources, implementing OAuth authentication, configuring storage backends for tokens/cache, adding middleware for logging/rate limiting, deploying to FastMCP Cloud, or troubleshooting module-level server, storage, lifespan, middleware order, circular imports, or OAuth errors. Keywords: FastMCP, MCP server Python, Model Context Protocol Python, fastmcp framework, mcp tools, mcp resources, mcp prompts, fastmcp storage, fastmcp memory storage, fastmcp disk storage, fastmcp redis, fastmcp dynamodb, fastmcp lifespan, fastmcp middleware, fastmcp oauth proxy, server composition mcp, fastmcp import, fastmcp mount, fastmcp cloud, fastmcp deployment, mcp authentication, fastmcp icons, openapi mcp, claude mcp server, fastmcp testing, storage misconfiguration, lifespan issues, middleware order, circular imports, module-level server, async await mcp
Apply when deciding, designing, or implementing FastStore theme customizations in src/themes/ or working with design tokens and SCSS variables. Covers global tokens, local component tokens, Sass variables, CSS custom properties, and Brandless architecture. Use for any visual customization of FastStore storefronts that does not require component overrides.
Design a Field Service Mobile Data Capture Flow from either a natural-language description OR a PDF/image of an existing paper form. Extracts field labels, types, required-state, and section structure into an intermediate JSON spec, confirms the plan with the user, then hands off to fs-data-capture-form-deployer for compile + deploy. Handles both input modes in one skill — prose ('build a Field Service form for asset inspection', 'make a DataCaptureFlow that asks the technician to…', 'create an inventory transfer form') and visual sources ('convert this PDF to a Data Capture Flow', 'make a Field Service form from this image', 'turn this paper form into a DataCaptureFlow'). Detects the input mode automatically from a .pdf/.png/.jpg/.jpeg path, else extracts from the prose. Do NOT use this skill to patch an already-deployed flow — that's fs-data-capture-form-editor.
Use when the user needs project structure organization — monorepo patterns, feature-based architecture, naming conventions, barrel exports, or configuration placement. Trigger conditions: restructure project directories, set up monorepo, define naming conventions, create barrel exports, organize configuration files, plan migration from flat to feature-based structure, establish import ordering rules.
Authoritative guide for Flutter framework APIs, widget lifecycle deprecations, design package unbundling, and version changelogs from Flutter 1.0 through Flutter 3.x+. Use this skill whenever authoring Flutter widgets, inspecting flutter sdk constraints, handling deprecated widgets (WillPopScope, withOpacity, MaterialState, FlatButton), migrating to standalone design libraries (material_ui, cupertino_ui), verifying widget API availability against the project's Flutter minSdk, or upgrading legacy Flutter applications.
Build and refactor Flutter widgets, forms with stale-safe asynchronous validation and duplicate-submit handling, widget previews, component APIs, and UI state boundaries. Use alone for form behavior over existing services; add networking or concurrency only when their infrastructure changes, and route visual polish, responsive layout, navigation, animation, and performance to their specialists.
Odoo frontend JavaScript patterns for website themes. Covers publicWidget framework (complete pattern with editableMode handling), Owl v1/v2 component patterns, _t() translation best practices, Bootstrap 4-to-5 migration, version detection, and critical development rules. Supports Odoo 14-19. <example> Context: User wants to create a publicWidget user: "Create a publicWidget for my Odoo website" assistant: "I will create a publicWidget with editableMode handling and proper cleanup." <commentary>publicWidget creation.</commentary> </example> <example> Context: User asks about Owl components user: "How do I create an Owl component in Odoo 18?" assistant: "I will show the Owl v2 pattern with static template and props." <commentary>Owl component pattern.</commentary> </example> <example> Context: User needs help with translations user: "How do I translate JavaScript strings in Odoo?" assistant: "Use _t() at DEFINITION TIME for static labels, not runtime wrappers." <commentary>Translation best practices.</commentary> </example> <example> Context: User migrating Bootstrap classes user: "Convert Bootstrap 4 classes to Bootstrap 5 for Odoo 17" assistant: "Replace ml-* with ms-*, mr-* with me-*, text-left with text-start." <commentary>Bootstrap migration.</commentary> </example>
Best practices for GameMaker Language (GML) development, covering scripts, object events, rooms, data structures, and performance-minded game code. Use when writing GML scripts or object event code in GameMaker Studio, structuring create/step/draw events, managing rooms and instances, building state machines for gameplay, or optimizing GML for performance.
Rust CLI reference for the headless-ghidra pipeline. Covers command syntax, flags, output contract, artifact paths, and workspace layout for all ghidra-agent-cli subcommands. Load when: constructing a ghidra-agent-cli command, interpreting its output, resolving a flag or artifact path question, or debugging CLI behavior. Do not load for P0–P4 workflow sequencing — use the headless-ghidra skill family instead.
Use when the user needs help with conventional commits, semantic versioning, changelog generation, or commit message quality improvement. Triggers: user says "commit", "version bump", "changelog", "commit message", staging changes for commit, preparing a release.
Set up Claude Code hooks to block dangerous git commands (push, reset --hard, clean, branch -D, etc.) before they execute. Use when user wants to prevent destructive git operations, add git safety hooks, or block git push/reset in Claude Code.
Guided Git workflow assistant. Helps with branching strategies, writing conventional commits, opening pull requests, resolving merge conflicts, and keeping history clean. TRIGGER when the user writes /git-workflow or asks for help with Git, branches, commits, PRs, or merge conflicts.

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.
