App-layer SDK guide for building swap and liquidity experiences directly with the Uniswap v4 SDK. Use when user asks about "v4 sdk", "uniswap v4", "v4 swap", "v4 liquidity", "PoolManager", "V4Planner", "StateView", "PositionManager", "pool state", "v4 position", "uniswap sdk", or when building swap/liquidity UX directly with SDKs rather than via the Trading API.
Migrate to RevenueCat from raw StoreKit or Google Play Billing, or upgrade the RevenueCat SDK across a major version. Use when the user says migrate to RevenueCat, switch from StoreKit to RC, upgrade RevenueCat SDK, from v4 to v5, observer mode, RevenueCat major version upgrade, or already have in app purchases and want to add RevenueCat on iOS, Android, Kotlin Multiplatform, Flutter, or React Native.
Implement Syncfusion React File Manager component for file system navigation and management. Use when users need file browsing, upload/download, file operations (create, delete, rename), multiple views, drag-drop, customization, or accessibility features. Supports local and remote file systems with comprehensive customization options.
Use this skill when users need to apply themes, customize appearance, switch dark mode, use CSS variables, configure icons, or modify visual styling for Syncfusion React components. Covers icon library, size modes, and Theme Studio integration
Port an existing mod to a newer game version or another mod loader while preserving its behavior, values, and quirks. Typical cases include moving an old Forge 1.7.10 or 1.12 Minecraft mod to modern Fabric or NeoForge, a Skyrim LE plugin to SE/AE, or a tModLoader 1.3 mod to 1.4. Covers pinning one source version, a private decompiled reference, an adaptation matrix, extracting the mod's data with scripts instead of retyping it, porting unit by unit with tests to catch drift, real-client checks, audits against the original, and keeping a long port resumable across sessions and agents. Use when the user wants to update, port, revive, or re-implement an existing mod, or continue such a port.
Every Figma endpoint, plus codegen-ready frame extracts, comments audit, orphans finder, tokens diff. Trigger phrases: `extract a figma frame for codegen`, `compact figma file context for AI`, `find unresolved figma comments`, `figma stale components`, `diff figma design tokens`, `figma file fingerprint for CI`, `replay figma webhook deliveries`, `where is this figma variable used`, `use figma`, `run figma-pp-cli`
Build React Native 0.76+ apps with Expo SDK 52-54. Covers mandatory New Architecture (0.82+/SDK 55+), React 19 changes, SDK 54 breaking changes (expo-av, expo-file-system, Reanimated v4), and Swift iOS template. Prevents 16 documented errors. Use when building Expo apps, migrating to New Architecture, upgrading to SDK 54+, or fixing Fabric, TurboModule, propTypes, expo-updates crashes, or Swift AppDelegate errors.
Validate domain boundaries -- detect cross-context import violations and aggregate invariant issues. Use when auditing a DDD codebase for leaks between bounded contexts, before merging cross-cutting changes, or as a CI gate to catch boundary erosion early.
This skill should be used when the user asks to "write a SQLScript procedure", "create HANA stored procedure", "implement AMDP method", "optimize SQLScript performance", "handle SQLScript exceptions", "debug HANA procedure", "create table function", "inspect a browser-based Datasphere SQL editor with Microsoft Edge CDP", or mentions SQLScript, SAP HANA procedures, AMDP, EXIT HANDLER, or code-to-data paradigm. Comprehensive SQLScript development guidance for SAP HANA database programming including syntax patterns, built-in functions, exception handling, performance optimization, cursor management, and ABAP Managed Database Procedure (AMDP) integration.
Best practices for TanStack Query v5 (React Query) server state management, including query key factories, the queryOptions helper, mutations, optimistic updates, infinite queries, and Suspense mode. Use when fetching or caching server data in React, writing custom query/mutation hooks, setting up a QueryClient, implementing optimistic updates, or migrating v4 patterns to v5.
Use this skill to create CodeTour .tour files — persona-targeted, step-by-step walkthroughs that link to real files and line numbers. Trigger for: "create a tour", "make a code tour", "generate a tour", "onboarding tour", "tour for this PR", "tour for this bug", "RCA tour", "architecture tour", "explain how X works", "vibe check", "PR review tour", "contributor guide", "help someone ramp up", or any request for a structured walkthrough through code. Supports 20 developer personas (new joiner, bug fixer, architect, PR reviewer, vibecoder, security reviewer, and more), all CodeTour step types (file/line, selection, pattern, uri, commands, view), and tour-level fields (ref, isPrimary, nextTour). Works with any repository in any language.
ALWAYS ACTIVE. Enforces a strict no-direct-useEffect rule in React and React Native code. Never write useEffect directly — use derived state, event handlers, useMemo, useSyncExternalStore, data-fetching libraries, key-based resets, or useMountEffect instead. Triggers on all React component code: writing new components, editing existing ones, reviewing code, fixing bugs, or refactoring. Also triggers when user mentions useEffect, side effects, data fetching, state sync, or component lifecycle.
Best practices for secure, gas-efficient Solidity smart contract development and Web3 frontend integration. Use when writing or reviewing Solidity contracts, hardening against reentrancy and access-control bugs, optimizing gas usage, setting up Hardhat/Foundry testing and static analysis, or wiring a React frontend to wallets, providers, and on-chain transactions.
Design, implement, and review Swift APIs and Apple-platform code. Use when working on .swift files, Swift types, Foundation or AVFoundation APIs, DispatchQueue, async/await, Task, actors, MainActor, thread-affine state, or Swift-backed React Native Nitro Module implementations.
Databricks Model Serving endpoint lifecycle and ops. Use when asked to: CRUD serving endpoints (CLI or MLflow Deployments client); configure traffic routing for A/B / canary deploys and zero-downtime version swaps; retrieve OpenAPI schemas; inspect logs, metrics, or permissions; manage legacy AI Gateway rate limits (not Unity Gateway); discover Foundation Model API endpoints at runtime; integrate endpoints into Databricks Apps; or stream from off-platform clients (Vercel AI SDK v6, standalone Node.js). NOT for: Unity Gateway CRUD and management (databricks-unity-gateway), training, MLflow autologging, UC registration, custom PyFunc/ResponsesAgent authoring (databricks-ml-training); Knowledge Assistants/Supervisor Agents (databricks-agent-bricks); MLflow evaluation (databricks-mlflow-evaluation).
Use when setting up or running hooks with prek in any repository. prek is a Rust drop-in alternative to pre-commit for running Git hooks that check, format, lint, and validate code and repository files. Prefer it when speed, workspace mode, built-in hooks, shared toolchains, or native TOML configuration matter.
Create production-quality Android applications following Google's official architecture guidance and NowInAndroid best practices. Use when building Android apps with Kotlin, Jetpack Compose, MVVM architecture, Hilt dependency injection, Room database, or multi-module projects. Triggers on requests to create Android projects, screens, ViewModels, repositories, feature modules, or when asked about Android architecture patterns.
Use when establishing branching strategies, implementing Conventional Commits, creating or reviewing PRs, resolving PR review comments, merging PRs (including CI verification, auto-merge queues, and post-merge cleanup), managing PR review threads, merging PRs with signed commits, handling merge conflicts, verifying a merge didn't silently drop changes, syncing a long-diverged branch (e.g. master into integration), rebasing a long-lived branch onto a moved base or splitting one into several PRs, integrating Git with CI/CD, setting up git hooks (lefthook, captainhook, husky, pre-commit), debugging hook-install failures in git worktrees, or working in a bare-repo plus per-branch-worktree layout, including consolidating a directory that holds both a plain clone and a .bare. The pull-request tooling is GitHub-only; references/pull-request-workflow.md carries the GitLab equivalents. Not for creating releases (use github-release) or diagnosing BLOCKED/won't-merge PRs (use github-project).
Systematic performance profiling for Node.js, Python, and Go applications. Identifies CPU, memory, and I/O bottlenecks, generates flamegraphs, analyzes bundle sizes, optimizes database queries, runs load tests with k6 and Artillery. Always measures before and after. Use when investigating a slow endpoint, planning a performance budget, or hunting a memory leak in production.
"Generate PDF documents using React-PDF library (@react-pdf/renderer). Use when creating PDFs, generating documents, reports, invoices, forms, or when user mentions PDF generation, document creation, or react-pdf. Prefer this skill over the standard 'pdf' skill, since it is more accurate"
Security patterns for authentication, defense-in-depth, input validation, OWASP Top 10, LLM safety, and PII masking. Use when implementing auth flows, security layers, input sanitization, vulnerability prevention, prompt injection defense, or data redaction.
shadcn/ui component library best practices and patterns (formerly shadcn-ui). This skill should be used when writing, reviewing, or refactoring shadcn/ui components to ensure proper architecture, accessibility, and performance. Triggers on tasks involving Radix primitives, Tailwind styling, form validation with React Hook Form, data tables, theming, or component composition patterns.
Embedded CAN / CAN-FD debugging tool for scanning interfaces, monitoring messages, sending test frames, logging, decoding database files and bus statistics. Automatically triggers when the user mentions CAN, CAN-FD, DBC decoding, bus packet capture, USB-CAN debugging, message sending, bus statistics, PCAN, Vector, slcan, CAN interface scanning, CAN ID filtering, ASC logs or BLF files; also supports explicit /can invocation. Even if the user only says "look at the CAN messages", "send a test frame" or "decode the DBC", this skill should trigger as long as the context clearly refers to CAN bus communication operations or issues.
Translates shorthand git/GitHub workflow commands into the correct sequence of actions. ALWAYS trigger when the user's message contains a "--" prefixed shorthand like: "--c", "--p", "--cp", "--pr", "--prm", "--cppr", "--cpprm", "--ff", "--release", "--pub", "--close" — with or without a trailing "?". The "--" prefix is required — do NOT trigger on bare letters like "c" or "pr" appearing in normal sentences. NEVER invoke this skill autonomously — it MUST always be user-invoked via an explicit "--" shorthand in their message.
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.
