An editorial-style poster—newsprint paper, dateline, oversized serif headline with a struck-through word and italic accent, a 2-column body block, and 6 numbered sections with annotated pull-quote captions. Reads like a Sunday-paper full-page essay or a thoughtful launch poster. Use when the brief asks for "magazine poster", "editorial poster", "newsprint", "essay layout", or "manifesto".
Change what agents run with — a permission rule, a global or project instruction, or a skill — to create, install, update, move, fork, publish, remove, or audit it with `npx skills`, and carry the change to every harness, machine, and install. Use when the user wants a rule or instruction added or changed, asks where one belongs, wants a skill created or changed, asks which skills they use or which name a default tool, or wants a workstation repo for their personal setup.
Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).
Execute database operations via Supabase MCP (query/write/migration/logs/type generation). Triggers: query/statistics/export/insert/update/delete/fix/backfill/migrate/logs/alerts/type generation. Does not trigger for: pure architecture discussion or code planning. Write operations require confirmation; UPDATE/DELETE without WHERE is refused.
Load when user says "mental model", "think through this", "structured thinking", "help me decide", "analyze this problem", "first principles", "pre-mortem", "stakeholder mapping", "what framework should I use", or any specific model name. Provides 59 thinking frameworks for decision-making, problem decomposition, and strategic analysis.
Use Mergify merge queue to queue/dequeue PRs, to monitor and inspect the queue, and to diagnose a dequeued PR — whether it is queued, why it was dequeued, where its CI failure is, and what to do next. ALWAYS use this skill when queuing or dequeuing a PR in the Mergify merge queue, checking its status, finding out why Mergify dequeued a PR, pausing/unpausing the Mergify merge queue, or debugging a merge the Mergify queue did not make. Triggers on mergify queue, @mergifyio queue, @mergifyio dequeue, Mergify merge queue, Mergify queue status, why did Mergify dequeue my PR, Mergify dequeue reason, Mergify queue pause, Mergify batch, Mergify bisecting, CHECKS_FAILED, PULL_REQUEST_UPDATED.
A mobile-app screen rendered inside a pixel-accurate iPhone 15 Pro frame on the page. Built by copying the seed `assets/template.html` and pasting one screen archetype from `references/layouts.md`. Use when the brief asks for "mobile app", "iOS app", "Android app", "phone screen", or "app UI"
Use when you need a runnable PyTorch training repo for a medical-imaging task (segmentation, classification, detection, synthesis, self-supervised, or fine-tuning a pretrained backbone). Emits a patient-level seed-locked split, train/evaluate scripts, config and a Methods stub.
Design for people with vestibular disorders, motion sensitivity, or seizure conditions. Use when designing animations, transitions, parallax scrolling, video backgrounds, carousels, or any moving content. Triggers on: motion, animation, vestibular, motion sickness, dizzy, nausea, parallax, autoplay, flashing, seizure, prefers-reduced-motion, spinning, scrolljacking.
Configure and validate Mercado Pago webhooks. Wraps the MCP webhook tools (save_webhook, notifications_history) and provides the HMAC-SHA256 signature validation pattern that every receiver must implement. Use when adding, debugging, or hardening notification handling.
Mutation-test a repo: find tests that would miss bugs. Measure test quality with mutation testing and close the gaps it finds. Use when asked whether tests are any good, when coverage is high but confidence is low, after AI wrote or changed tests, or when the user mentions mutation testing, mutation score, surviving mutants, or names a mutation tool (Stryker, Pitest, mutmut, Infection, cargo-mutants)
Write JavaScript code in n8n Code nodes. Use when writing JavaScript in n8n, using $input/$json/$node syntax, making HTTP requests with this.helpers / the $helpers global, working with dates using DateTime, troubleshooting Code node errors, choosing between Code node modes, or doing any custom data transformation in n8n. Always use this skill when a workflow needs a Code node — whether for data aggregation, filtering, API calls, format conversion, batch processing logic, or any custom JavaScript. Covers SplitInBatches loop patterns, cross-iteration data, pairedItem, and real-world production patterns. Also use when asked why a Code node or workflow is slow, which execution mode is faster, or how to cut per-item overhead on large datasets. EXCEPTION — for the AI-agent-callable Custom Code Tool (@n8n/n8n-nodes-langchain.toolCode, a tool attached to an AI Agent), use the n8n-code-tool skill instead; it has a different runtime contract.
Run candidate product, brand, company, or benchmark names through an audition — authoritative domain-availability checks, collision research across SaaS/GitHub/packages/the target adjacent domain, a light trademark and ownability read, a ranked callback list, and an interactive casting report of finalists with optional draft branding. Use when the user is naming a product, app, company, feature, or benchmark; asks "is this name taken", "check these domains", "help me pick a name", "is X available", "name my product", "brand name research", "audition names"; or wants to compare and pressure-test a shortlist of candidate names before committing.
Generate images using Nano Banana Pro (Gemini 3 Pro Preview). Use when creating app icons, logos, UI graphics, marketing banners, social media images, illustrations, diagrams, or any visual assets. Supports reference images for style transfer and character consistency. Triggers include phrases like 'generate an image', 'create a graphic', 'make an icon', 'design a logo', 'create a banner', 'same style as', 'keep the style', or any request needing visual content.
Draft, revise, or critique a primary-research manuscript for a specifically chosen Nature or Nature Portfolio journal, or deliberately develop that broad-reader scientific style. Ground claims in the supplied results and calibrate journal requirements separately. Do not impose this journal style on generic documentation, reviews, press releases, or unrelated writing.
Prepare manuscripts for Nature and Nature Portfolio journals (Nature, Nature Communications, Nature Methods, Nature Biotechnology, Scientific Reports and other Nature-branded titles), covering article types, summary paragraph vs abstract, main-text and display-item limits, Methods and Extended Data, reporting summaries, data/code availability, figure preparation, references and presubmission enquiries. Use when targeting any Nature Portfolio journal, reformatting a paper for one, or checking a submission against its guidelines
Highest-priority for all Next.js-related tasks involving full-stack web development. Use this skill whenever writing, reviewing, refactoring, debugging, or planning Next.js code using App Router, Server Components, Client Components, API Routes, Server Actions, data fetching, caching, revalidation, routing, authentication, or Next.js tests. Prefer this skill over generic React or Node.js advice for Next.js code.
Guide for drafting dismissal notifications compliant with French labour law. Use this skill when the user asks to draft, prepare, create, or edit a dismissal notification letter, in particular for serious misconduct, gross misconduct, or personal grounds. The skill guides the collection of precise information and the drafting of a legally sound notification with all the mandatory elements of French law.
(NS) PostgreSQL retrieval — pgvector, hybrid FTS+vector, GraphRAG tables, multi-hop, 1MM+ scale. Use for RAG or GraphRAG on Postgres, pgvector, hybrid search, document links, entity merge, multi-hop, or 1MM+ retrieval — even if they say search, embeddings, or knowledge graph in SQL. Do NOT use for ontology/cite-or-refuse (`ns-graphrag`), app code, competing vector DBs, CrewAI, or generic web apps.
Use Obsidian's official CLI to work with a running Obsidian app and its configured vaults. Use for live workspace state, indexed search and metadata, daily notes, tasks, links and backlinks, Bases, templates, bookmarks, plugins, themes, Sync status, and developer inspection. Prefer ordinary filesystem tools when the task only needs direct file reads, writes, listing, or text search.
Apply Odoo 18-20 best practices for module architecture, ORM patterns, XML views, OWL components, security, testing, and performance, plus dev environment setup and an official documentation index. Use when developing, reviewing, or debugging Odoo custom modules or setting up an Odoo development environment.
Open Orbit briefing skill — selected by the Orbit pipeline when GitHub is the user's only connected connector, or when the user explicitly scopes their daily digest to GitHub. Pulls the past 24 hours of PRs, review requests, issues, CI runs, and merges from the user's authenticated GitHub connection and renders them in a layout that mirrors GitHub's native Notifications + PR-diff visual language. This skill should not be triggered manually — it is invoked by Orbit's daily-digest scheduler against live GitHub data.
Dependency-graph-style task breakdown on PLAN.md — answers 5 questions (what does this task need · what runs in parallel · what does it depend on · why does it exist in the graph · how does it relate to the old graph) with deterministic tools, dispatch by topo layer with LOCK + lease + generation, state persisted append-only (events.jsonl), 2 Python files for drawing (1 graph / 2D atlas of all graphs), every model answer labelled sure|suggestion|unknown + source, fabrication audit = 0. Invoke when the user says "orca-graph", "graph phân việc", "task nào song song", "phụ thuộc gì", "vẽ graph task", "dispatch theo graph", "/orca-graph".
Transforms an academic paper into deep, multi-layered understanding. Use when asked to explain a paper, break down a research paper, understand an arXiv paper, or build intuition for a technical concept from a paper. Generates explanations at multiple levels plus visual intuition diagrams.
When the user wants to optimize pharmaceutical supply chains, manage cold chain logistics, ensure regulatory compliance, or implement serialization. Also use when the user mentions "pharma supply chain," "GMP compliance," "cold chain," "drug serialization," "clinical trials logistics," "pharmaceutical distribution," "good distribution practices," "GDP," "drug safety," or "pharmaceutical quality." For general healthcare, see hospital-logistics. For clinical trials specifically, see clinical-trial-logistics.
Use when the user asks for their total Pionex portfolio value, full balance overview across all account types (spot + bots + dual investment + trader account), USDT/BTC grand total, or wants to know how much they have in bots vs spot. Read-only; requires API credentials. For spot coin list only, use pionex-portfolio instead.
Drive a live browser from the CLI with playwright-cli to navigate, interact, snapshot, and capture evidence. Use for ad-hoc browser commands, page inspection, screenshots, traces, network mocking, session management, or interactive debugging—not authoring @playwright/test specs. Keywords: playwright-cli, browser automation, live session, snapshot, console, tracing.
Presentation creation, editing, and analysis. When Claude needs to work with presentations (.pptx files) for: (1) Creating new presentations, (2) Modifying or editing content, (3) Working with layouts, (4) Adding comments or speaker notes, or any other presentation tasks
Review one PR as a guided tour, in a sane reading order. Turn one pull request into a guided reading tour: the author's intent, which files that intent explains and which it does not, and checkable claims first, then where to look and why (script-computed facts plus line-checked pointers), then the files in the order a reviewer should read them with each test next to its code, and noise (lockfiles, generated files, renames, formatting) collapsed last — rendered as one self-contained HTML page plus JSON that agents can read. Not GitHub stacked PRs. Use when the user asks to review, walk through, explain, or understand a PR or diff, asks what to read first or what to worry about in a PR, or mentions PR tour or reading order
Full Prism: multi-pass structural analysis with mandatory adversarial self-correction. Designs custom analytical passes, executes them with chaining, then attacks its own findings before synthesizing. Use for maximum depth on important code or artifacts.
Programmatic SEO planning and audit: building or evaluating large sets of template-generated pages that target long-tail query patterns (e.g. "[service] in [city]", "[product] vs [product]", "[tool] for [use-case]"). Covers data-source and template design, thin/duplicate-content and doorway-page risks, per-page uniqueness and value thresholds, internal linking and hubs, indexation management (publish vs. noindex), and scaling without a manual action. Use whenever the user wants to generate many pages from a template/dataset, build location/comparison/use-case pages at scale, or asks why generated pages aren't indexing. Trigger on: "programmatic SEO", "pSEO", "generate pages at scale", "templated pages", "location pages at scale", "comparison pages", "[city] pages", "my generated pages aren't indexed", "doorway pages", "scale content". For one-off content use /content-writer; for keyword discovery use /keyword-research.
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.
