Design, implement, and review React interfaces with composition, state, effects, concurrency, accessibility, performance, and testing. Use when a task involves React components, hooks, context, forms, or client-side rendering; use the Next.js skill when the framework defines server/client boundaries
Discover the Databases (check-sources) Sumsub offers for a country, whether each is enabled for the tenant, and how database / non-document (eKYC) verification fits into a verification level. Use WHEN a user asks which database / non-document check-sources are available for a country, whether they're enabled, or how to add database validation / non-doc identity / non-doc address verification to a level. Also called by sumsub-create-level before placing those sources. Do NOT use for document-only verification or entitlement checks (use sumsub-check-permissions).
Postgres best practices maintained by Supabase, for Postgres running anywhere. Load this skill BEFORE writing or changing anything that lives in a Postgres database: creating or altering tables and columns (including choosing column types), schema design, migrations and declarative schema files, RLS policies and the tests that verify them, indexes, triggers, database functions, queues and scheduled jobs (pg_cron, pgmq), vector/semantic search (pgvector), and restoring dumps (pg_restore) or importing data. Also load it when diagnosing slow queries, high CPU, timeouts, EXPLAIN plans, connection exhaustion, locking, bloat, or rows visible to the wrong user or tenant. This is not just a performance guide — schema, migration, security, and SQL authoring tasks need these rules too, even for a one-column change or a single query.

Make a short procedural animation in any style — an explainer, a history, a little story — as a single-file canvas video with a synthesized score, rendered to MP4. Ships with styles (cut paper, crosshatch ink, riso print, sketchbook, manim-style math, pixel art, isometric line art) and makes new ones from the user's references. Walks the user through intake, then three check-ins (story, look, storyboard) before animating, and proves the result with measured review checks. Use when the user asks for an animated video, short, explainer or reel made in code, or wants a look matched from references.

Covers phrases like "Base RPC URL", "Base chain ID", "connect to Base", "add Base to wallet", "Base Sepolia config", "Base explorer URL", "what network is Base", or "Base testnet setup".
Cross-file consistency audit of docs, templates, manifests (package.json, plugin.json, .mcp.json), installer scripts, and instruction files (CLAUDE.md, AGENTS.md, SKILL.md): flags drift, and content restated in several places instead of referenced from one; skips credential files. Use for "check consistency", "in sync", "find inconsistencies", "verify everything is updated", "single source of truth", "restated in multiple places". Offer proactively—asking first—after any README, SKILL.md, CLAUDE.md, AGENTS.md, template, plugin.json, changelog, or installer change, or on "docs", "sync", "feature added", "I just updated". `review-intentional` re-surfaces suppressed findings.
Composite any two HTML screens into a locked photo plate of hands holding an open foldable phone — a 1448×1086 still with two blank 495×849 / 498×849 screen slots (left and right) — to make side-by-side meme and comparison videos: TikTok vs Reels, ChatGPT vs Claude, "me vs my friend", before/after, two apps racing. Trigger on: "foldable phone meme", "put X on the left screen and Y on the right", "two-screen comparison video", "the dual-screen phone meme", or any request that names two apps/feeds/chats to show at once. The plate, geometry, and camera are finished — the agent only authors what plays INSIDE the two screens and renders.
Multi-provider email sending for Cloudflare Workers and Node.js applications. Build transactional email systems with Resend (React Email support), SendGrid (enterprise scale), Mailgun (developer webhooks), or SMTP2Go (reliable relay). Includes template patterns, webhook verification, attachment handling, and error recovery. Use when sending emails via API, handling bounces/complaints, or migrating between providers.

Use when preparing for exams, creating study plans, building review materials, or organizing exam preparation. Triggers - exam prep, test preparation, study schedule, review sheet, practice test, exam study plan.
Find the expansion whitespace in an account or a book: what they own versus what they could own, the evidence for each play, and the open opps to create.

Use for designing the game world, deepening gameplay and levels, writing the game design document, or designing branching story structure, scenes, dialogue, and consequences. 游戏体验、系统与关卡策划。将选定概念收束为一份 GAME_DESIGN，定义核心体验目标、玩法循环、世界反馈、必要系统、关卡节奏、操作反馈、失败重开及可供构建的完整可玩范围。用于设计游戏世界、深化玩法和关卡、设计互动叙事的场景对白与分支因果等需求。
Remove signs of AI-generated writing from prose, and keep it out of a repo. Use when drafting, editing, or reviewing text to make it sound natural and human, or when auditing a whole docs folder for AI slop. Detects 41 patterns across content, language, style, communication, filler, and rhetoric, including: significance inflation, promotional language, -ing tails, vague attributions, AI vocabulary, copula avoidance, negative parallelisms, false agency, em dash overuse, chatbot artifacts, hedging stacks, staccato drama, and aphorism formulas.

Job-hunting hunter main entry point. Upload screenshots of job details pages from recruitment platforms (Boss直聘, 智联招聘, 前程无忧, etc.) to compare against your resume using STAR analysis, generate a tailored resume and opening message, and produce a match-ranked shortlist. Supports subcommands: fetch / analyze / tailor / status / clean
When the user wants to plan a product launch, feature announcement, or release strategy. Also use when the user mentions 'launch,' 'Product Hunt,' 'feature release,' 'announcement,' 'go-to-market,' 'beta launch,' 'early access,' 'waitlist,' or 'product update.' This skill covers phased launches, channel strategy, and ongoing launch momentum.
Run any question, idea, or decision through a council of 5 AI advisors who independently analyze it, peer-review each other anonymously, and synthesize a final verdict. Based on Karpathy's LLM Council methodology. MANDATORY TRIGGERS: 'council this', 'run the council', 'war room this', 'pressure-test this', 'stress-test this', 'debate this'. STRONG TRIGGERS (use when combined with a real decision or tradeoff): 'should I X or Y', 'which option', 'what would you do', 'is this the right move', 'validate this', 'get multiple perspectives', 'I can't decide', 'I'm torn between'. Do NOT trigger on simple yes/no questions, factual lookups, or casual 'should I' without a meaningful tradeoff (e.g. 'should I use markdown' is not a council question). DO trigger when the user presents a genuine decision with stakes, multiple options, and context that suggests they want it pressure-tested from multiple angles.
This skill should be used when Claude needs to build or reuse a reusable Make API-call shell by discovering the correct app-specific Make an API Call module, resolving or requesting the right connection, explicitly setting the scenario interface, running the scenario, and using that shell as the retrieval transport for email, CRM, tickets, and similar SaaS systems.
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.
