WooCommerce extension code review for HPOS compatibility, payment gateway security, cart optimization, and template overrides. Use when reviewing WooCommerce extension code, payment gateway development, shipping methods, custom product types, cart operations, checkout customization, or when user mentions "WooCommerce review", "WooCommerce extension", "WooCommerce plugin", "payment gateway", "shipping method", "HPOS", "High-Performance Order Storage", "wc_get_orders", "WC_Payment_Gateway", "WC_Shipping_Method", "cart fragments", "WooCommerce hooks", "WooCommerce template", "shop_order", "WooCommerce performance", "Action Scheduler", "WooCommerce REST API", "WooCommerce Blocks", "checkout block", "woocommerce_checkout". Detects HPOS issues, CRUD violations, payment security anti-patterns, performance problems, and template override mistakes in WooCommerce 8.2+ through 10.x code.
Quickly build WeChat automation bot applications. Use this skill when the user wants to create a WeChat bot, listen for WeChat messages, auto-reply, handle WeChat group messages, send WeChat messages, post to Moments, fetch Moments content, or has any need related to WeChat automation. Supports message listening, auto-reply, group management, friend management, Moments operations, full message listening, and more.
This skill MUST be called for optimizing 1C queries: temp tables, JOIN vs subqueries, virtual table parameters, DCS, indexes. SHOULD also be called for slow queries and performance diagnostics. Do NOT use for basic query syntax — use 1c-help-mcp.
Writes a hands-on developer guide for one ADK code unit — a minimal runnable example, how it works, a configuration-option table, advanced uses, limitations, and links to related samples — to `docs/guides/{topic}/{unit}/index.md`, then lists it in the index at `docs/guides/README.md`. Its reader is a developer calling the unit from their own application, at more depth than the published adk.dev documentation carries. Use when asked to "write a unit guide for {class}", "document how to use {feature}", "add a guide for {file}", or after shipping a user-facing class, node, or plugin. Don't use for internals documentation aimed at someone changing or extending the unit — that is a design document under `docs/design/` (use `adk-unit-design`). Don't use to write a runnable sample under `contributing/samples/` (use `adk-sample-creator`).
This skill should be used before drafting an ADR when context, components, relationships, deciders, or prior decisions are unclear. PROACTIVELY activate on "I want to write an ADR for X", "gather context for a decision", "discovery for an ADR", "ADR intake", "ADR pre-flight", "prep work before an ADR", "what's the current architecture?", or "set up a decision log." Provides: zero-hallucination Q&A, human-confirmed discovery brief, open-questions register, and five required confirmations before drafting.
This skill should be used when a decision is ready to become an ADR and the user wants co-thinking rather than template filler. PROACTIVELY activate on "draft the ADR", "write up the decision", "co-think this ADR", "challenge my reasoning", "ADR for X", "MADR for X", "Y-statement for X", "we decided to use X", "co-draft", "ADR drafting", or "scripted push-back." Provides: seven-phase ADR drafting, one-question turns, failure-mode pressure test, and self-critique against the ADR-is-NOT checklist.
Add agent-friendly --json NDJSON output to Python CLI scripts, or scaffold a complete cli_utils package for a project. Use this skill when the user wants to make scripts machine-readable for AI agents, add --json flags, convert print statements to structured JSON, build a CLI helper library, create an open-source CLI-for-agents package, add structured logging, or make CLI output machine-readable. Also use when the user mentions NDJSON, structured CLI output, agent-friendly CLI, non-interactive scripts, or JSON I/O for automation.
Guides Android app development with Kotlin including creating Activities, Fragments, ViewModels, Jetpack Compose UI, Navigation, Gradle configuration, and app signing. Use when the user asks about Android Kotlin development, needs to create Android applications, implement Jetpack components, or configure build variants.
Use this skill to design an OpenAPI spec from scratch, assess an existing spec for AI agent readiness, security, or design quality, or fix issues found in a spec. Trigger when the user describes an API they want to build, asks to "design", "create", "draft", or "scaffold" an OpenAPI spec, or mentions building a REST API for a service or domain. Trigger when the user says things like "I want to expose endpoints for X", "help me design an API for Y", or "I need an OpenAPI spec for Z" — even without saying "OpenAPI" explicitly. Trigger when the user asks to evaluate, review, check, or assess an OpenAPI spec for agent compatibility, API quality, security, OWASP compliance, WSO2 guidelines, or REST best practices — or when they share a .yaml/.json OpenAPI file and ask how good it is. Trigger when the user asks to fix, correct, remediate, or apply fixes to issues in an OpenAPI spec — including "fix issue spec-001", "fix all HIGH severity issues", "apply autoFixable fixes", or "fix the spec issues from this report".
Examples and a structure audit for the Architecture rules in AGENTS.md. Those rules are always on. Use this skill to draft a structure card or see good and bad shapes, not as the source of the rules. Triggers: folders, services, data reads, SITE_URL, auth on writes, Date.now in queries.
Implement proven backend architecture patterns including Clean Architecture, Hexagonal Architecture, and Domain-Driven Design. Use when architecting complex backend systems or refactoring existing applications for better maintainability.
Builds local vector search, RAG, embeddings, and semantic search on the Azure SQL Database container using the native VECTOR type and VECTOR_DISTANCE. Use when you need to store embeddings, do similarity search, top-k nearest neighbor, cosine distance, retrieval-augmented generation, "find similar documents", chatbot memory, or semantic lookup against a local SQL database. Use this instead of pgvector, FAISS, Chroma, Pinecone, or a separate vector store when the data already lives in (or can live in) Azure SQL. Covers the VECTOR(n) column type, inserting embeddings with CAST(CAST(? AS NVARCHAR(MAX)) AS VECTOR(n)) where the dimension is a literal, a pluggable embed() so only the endpoint changes for cloud, and a working CREATE VECTOR INDEX with the two errors that block it. Provisions appdb on master first so every script runs on a fresh container.
Use when profiling Bevy 0.20 with `DiagnosticPath`, `DiagnosticsStore`, `info_span!`, `RenderDiagnosticsPlugin`, or the `RenderDebugOverlay`: custom metrics, CPU/GPU pass timings, queue/task/upload telemetry, stale-result counts, and native, Steam Deck, or WebGPU budgets
Use when building Bevy 0.20 input with `InputSystems`, entity-based `Gamepad`/`GamepadSettings`, `AccumulatedMouseMotion`, or `CursorOptions`: rebindable actions, hot-plugging, deadzones, Steam Deck, accessibility controllers, and correct transfer into `FixedUpdate`
Blutui project guidelines from the Blutui Engineering team. Use this skill whenever working on ANY Blutui project — writing or editing templates, layouts, components, or partials; creating or querying Collections; building or handling forms; configuring routing or Courier; working with Canopy or Cassettes; using the Blutui MCP; or setting up a new Blutui project from scratch. If the user mentions Blutui, Canopy, Cassettes, Courier, or any Blutui-specific concept, always load and follow this skill before writing any code or configuration.
Use before any creative work - creating features, building components, adding functionality, or modifying behavior. Triggers on /brainstorm command, when exploring ideas before planning, when user describes a vague goal or feature request, or when design decisions need collaborative exploration. Explores user intent, requirements and design before implementation.
Commit, push, branch, and manage version control. Use for git commit, git status, git push, git diff, creating branches, staging files, editing history, pull requests, or any git/version control operation. Replaces git write commands with 'but' - always use this instead of raw git.
Upgrades a Capacitor plugin library from v8 to v9 (prerelease, @next until GA). Runs `npx @capacitor/plugin-migration-v8-to-v9@latest`, then the manual checklist - peer/dev dependency ranges, removed Android APIs (@NativePlugin, saveCall, pluginRequestPermission, int-code startActivityForResult, CapConfig getters, PluginCall.save/isSaved/hasOption), removed iOS APIs (CAPBridge class, getWebView, isSimulator, presentVC, CAPNotifications), AGP 9.2.1 / Gradle 9.5.1 build.gradle edits (compileSdk 37, minSdk 26, no targetSdk, built-in Kotlin, core-ktx to core, unique namespace, no jcenter, proguard-android-optimize.txt), iOS 16 in podspec and Package.swift, dropping the Cordova SPM product, and UIScene lifecycle observers. Use for "update my plugin to Capacitor 9", "Cannot find 'CAPBridge' in scope", NativePlugin compile errors, AGP 9 namespace collisions. Do not use for apps (use capacitor-app-upgrade-v8-to-v9), the 8.5 UIScene app step (use capacitor-uiscene-migration), or older majors.
Code graph navigation, semantic code search, and impact analysis. Use when the user asks "where is X defined?", "what calls X?", "who imports X?", "what depends on X?", "how is X used?", "where is X called from?", "what breaks if I change X?", "is it safe to change/delete X?", "help me refactor X", "show me the call graph", "trace the execution flow", "find all usages of X", "find code related to...", "show me how X works", "show me the X implementation", "show file structure", "list all functions/classes in a file", "show the inheritance tree", "show class hierarchy", or needs to navigate code, locate definitions, search code by concept or behavior, trace dependencies, assess blast radius of changes, explore how a feature is implemented, support refactoring (rename, extract, move, delete), or explore an unfamiliar codebase. Supports Python, TypeScript/JavaScript, Rust, Go, Ruby, Java, C, C++, C#, PHP, Dart, Swift, Kotlin, Vue, Svelte, Astro, and Markdown documents, plus React/JSX and Vue/Svelte/Astro component-usage edges.
Write idiomatic application code with the ClickHouse Node.js client (`@clickhouse/client`). Use this skill whenever a user is *building* against the Node.js client — configuring the client, pinging, inserting rows in JSON or raw formats, selecting and parsing results, binding query parameters, managing sessions and temporary tables, working with data types or customizing JSON parsing. Do NOT use for browser/Web client code.
Use this skill when discovering and comparing cloud-native technologies from the CNCF Landscape for an architecture or engineering decision. Query the live public Landscape API, filter candidates by capability, category, maturity, license, and repository signals, then produce an evidence-backed shortlist with trade-offs, unknowns, and validation steps. Do not use it as a substitute for project documentation, production-readiness testing, legal review, or general architecture methodology.
Set up, index, and manage SocratiCode codebase indexing. Use when the user wants to index a project, check infrastructure health, start/stop file watching, configure context artifacts, troubleshoot indexing issues, manage the code graph, or any SocratiCode administrative task. Activates when the user mentions indexing, setting up search, SocratiCode infrastructure, or managing the codebase index.
Manage custom business configuration in an Adobe Commerce app. Use when the user wants to add, modify, or remove merchant-configurable settings (config fields, admin config, store configuration) exposed through Commerce Admin. Creates typed config fields (text, password, email, url, tel, boolean, list) in businessConfig.schema. Requires a base app initialized with commerce-app-init.
Build, refactor, debug, or review a Convex backend inside a Next.js app. Use when the user mentions Convex, `convex/nextjs`, `npx convex dev`, `NEXT_PUBLIC_CONVEX_URL`, `useQuery`, `useMutation`, `usePaginatedQuery`, schema/indexes, auth, App Router server components/actions, realtime data, chat, notifications, collaborative features, or deploying Convex with Vercel. Also use when deciding whether Convex is a good fit for a Next.js app that needs reactive shared state. Do not use for generic frontend-only Next.js work or non-Convex backends unless the task is specifically about adopting, migrating to, or evaluating Convex.
Build applications powered by GitHub Copilot using the Copilot SDK. Use when creating programmatic integrations with Copilot across Node.js/TypeScript, Python, Go, or .NET. Covers session management, custom tools, streaming, hooks, MCP servers, BYOK providers, session persistence, custom agents, skills, and deployment patterns.

Use when a complex problem seems unsolvable and needs digging to the essence — diagnosis only, not fixing. Symptoms include massive logs with no root cause surfaced, complex crashes, architectural essence analysis, requirement authenticity verification, systemic chronic issues, information overload, disconnect between symptoms and essence, multiple intertwined factors, or premature-convergence tendencies — even when the user never explicitly says "diagnose". Also triggers on 本质诊断, 根因诊断, 深度诊断, 诊断问题本质, 梳理问题逻辑, 证据链分析, 逻辑链分析, essence-diagnosis.
Apply when deciding, designing, or implementing data fetching with FastStore GraphQL files in src/graphql/ or src/fragments/, or configuring faststore.config.

Patch an existing Data Capture Flow that's already deployed in a connected Salesforce org. Retrieves the live Flow Metadata JSON via the Tooling API, applies the user's requested change, and PATCHes it back. Use when the user names an existing flow and asks to add/remove/rename a field, change visibility, fix a bug, add visual polish, or swap a placeholder for a real component ('add a Notes field to Inventory_Transfer', 'fix the visibility rule on Work_Order_Number', 'make the parts repeater optional', 'replace the Signature placeholder with the real dcSignature component'). Do NOT use this skill to build a brand-new flow — that's fs-data-capture-form-designer followed by fs-data-capture-form-deployer.
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.
