Orchestrate Unity Editor via MCP (Model Context Protocol) tools and resources. Use when working with Unity projects through MCP for Unity - creating/modifying GameObjects, editing scripts, managing scenes, running tests, or any Unity Editor automation. Provides best practices, tool schemas, and workflow patterns for effective Unity-MCP integration.
Update Remotion’s ffmpeg-next Git revision to a published rust-ffmpeg commit, refresh Cargo.lock, rebuild all supported compositor binaries, validate the monorepo, and open a draft pull request. Use for the final step of the rust-ffmpeg binary update chain.
Vitest testing framework patterns and best practices. Use when writing unit tests, integration tests, configuring vitest.config, mocking with vi.mock/vi.fn, using snapshots, or setting up test coverage. Triggers on describe, it, expect, vi.mock, vi.fn, beforeEach, afterEach, vitest.
When the user wants to improve their ability to genuinely understand the buyer's situation and pressures. Also use when the user mentions "understanding buyers," "buyer's perspective," "walking in their shoes," "emotional intelligence," "reading customers," or "connecting with prospects."
Search Google Hotels for hotel prices, ratings, and availability using browser automation. Use when the user asks to search hotels, find accommodation, compare hotel prices, check availability, or look up places to stay. Triggers include “search hotels,” “find hotels,” “hotels in,” “where to stay,” “accommodation,” “hotel prices,” “cheapest hotel,” “best hotel,” “places to stay,” “hotel near,” “book a hotel,” and “hotel ratings.”
Testing Inertia Rails responses with RSpec and Minitest: component assertions, prop matching, flash verification, deferred props, and partial reload helpers. Use when writing controller specs, request specs, or integration tests for Inertia pages. ALWAYS use matchers (render_component, have_props, have_flash), NOT direct access (inertia.component, inertia.props). CRITICAL: after POST/PATCH/DELETE with redirect, MUST call follow_redirect! before asserting flash or props — without it you're asserting against the 302, not the Inertia page. Setup: require 'inertia_rails/rspec'.
Generate publication-quality academic illustrations through a local Codex app-server bridge that uses Codex native image generation. This is a separate experimental alternative to `paper-illustration`, intended for Claude Code users who want a GPT-image-style renderer without modifying the original skill.
Reviews, writes, and refactors ReactLynx code and component libraries for Lynx dual-thread best practices. Applies when writing ReactLynx components, or handling background-only, useLayoutEffect, bindtap/catchtap, main-thread:*, runOnMainThread/runOnBackground, lazy/Suspense, globalPropsMode/__globalProps, component-library publishing (preserved JSX vs React.createElement), or render/diff/commit performance traces. Excludes vanilla Lynx Element PAPI without ReactLynx JSX (use vanilla-lynx), running-app debugging via DevTool/CDP (use lynx-devtool), or Rspeedy/tsconfig config (use lynx-typescript).
Automatically publish text-and-image or video content to Xiaohongshu (XHS), with support for login checks, content search, and engagement actions. Use cases: publish text-and-image posts, publish videos, launch a test browser only, get a login QR code, scrape homepage recommendations, search posts, interact through comments, and scrape content data.
Use SurrealKit, SurrealDB's schema-management and migration CLI, to scaffold projects from templates, sync schema in development, plan and execute production rollouts (with rollback), statically check SurrealQL without a database, generate JSON/TypeScript types, and write declarative TOML test suites for schemas, permissions, and API endpoints. Use this skill whenever users set up, migrate, type, check, or test a SurrealDB schema with SurrealKit.
MUST be used right after changing any CLI color config (delta/bat/themes/lazygit pager) — renders the terminal's colored output to a PNG so Claude can actually SEE contrast, alignment, and highlighting instead of raw ANSI codes. Use for delta git diff colors, bat syntax highlighting, starship prompt, eza/ls colors, or ripgrep matches. Trigger phrases: 看终端效果, 终端截图, 验证配色, terminal screenshot.
Quickly assess a stock’s current valuation, historical percentile, relative position among peers, and conditions for revaluation. Useful for first judging whether it is “expensive,” screening valuation levels, and discussing risk-reward and expectations.
Browser automation CLI for AI agents. Use when the user needs to interact with websites, including navigating pages, filling forms, clicking buttons, taking screenshots, extracting data, testing web apps, or automating any browser task. Triggers include requests to “open a website”, “fill out a form”, “click a button”, “take a screenshot”, “scrape data from a page”, “test this web app”, “login to a site”, “automate browser actions”, or any task requiring programmatic web interaction.
Systematically evaluate cyber-campaign evidence to attribute an operation to a threat actor, using the Diamond Model and Analysis of Competing Hypotheses (ACH) to weigh infrastructure overlaps, TTP consistency, malware code similarity, and timing/language artifacts into confidence-weighted attribution assessments. Use when an incident investigation needs a defensible attribution confidence level
Create complete documentation sites for projects. Use when asked to: "create docs", "add documentation", "setup docs site", "generate docs", "document my project", "write docs", "initialize documentation", "add a docs folder", "create a docs website". Generates Docus-based sites with search, dark mode, MCP server, and llms.txt integration.
Send messages, embeds, and marketing content to Discord channels via webhooks or bot API. Manage community engagement, announcements, and automated posting. Trigger phrases: "post to discord", "discord message", "discord webhook", "discord embed", "discord announcement", "send to discord", "discord community", "discord marketing"
Use when protecting Express or Node.js API endpoints with JWT Bearer token validation, scope-based access control, or DPoP binding. Integrates express-oauth2-jwt-bearer — use even if the user says "validate tokens in my Express API" or "protect my Node.js API endpoints".
Industrial AI literature research with mandatory intake questions, venue-aware source prioritization, structured report outputs, and survey draft generation. Use when the user needs up-to-date research on predictive maintenance, intelligent scheduling, industrial anomaly detection, smart manufacturing, cyber-physical systems, edge AI for automation, or crossover robotics-for-industry topics. Also trigger for adjacent terms: "digital twin", "industrial IoT", "Industry 4.0", "manufacturing AI", "factory automation", "process optimization", or "survey draft" in industrial contexts.
Write publication-ready ML/AI papers for NeurIPS, ICML, ICLR, ACL, AAAI, COLM. Use when drafting papers from research repos, conducting literature reviews, finding related work, verifying citations, or preparing camera-ready submissions. Includes LaTeX templates, citation verification workflows, and paper discovery/evaluation criteria
Monetization strategy for iOS/macOS apps. Covers readiness assessment, pricing model selection, tier structuring, free trial strategy, and implementation guidance. Use when deciding what to charge, how to price, or planning monetization end-to-end.
Use this skill when the user needs NetSuite-based finance analysis, Director of Financial Analysis support, period-close guidance, variance review, reconciliation review, cash reporting, or executive-ready financial narrative generation. Apply it to requests involving income statements, balance sheets, cash flow, budget versus actuals, AR or AP aging, month-end close, SOX-oriented finance checks, journal entry review, and board or CFO reporting. Prefer it when the request clearly involves NetSuite financial data interpretation or finance operations, but do not use it for general NetSuite development or non-finance administration tasks.
Trigger Novu notification workflows to send messages across email, SMS, push, chat, and in-app channels. Supports single triggers, bulk triggers, broadcast to all subscribers, topic-based targeting, and cancellation. Use when sending transactional notifications, alerts, or any event-driven messages.
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.
