Integrates computed statistical results (DEGs, GWAS hits, associations) with biological context from ToolUniverse databases (UniProt, GO, Reactome, ClinVar, OpenTargets). Use to add gene function, pathway, and disease annotations to a result list, build a biological narrative around statistical findings, and go beyond p-values to mechanisms.
Create a narrated demo video of a web app. Use when the user asks for a demo video, product walkthrough video, launch video, or to re-run or update an existing one. Takes an app URL, test credentials, and a content brief; produces an MP4 (plus vertical/GIF variants) via scout → script checkpoint → capture → TTS → render.
Always use when building realtime features with Ably — messaging, chat, collaboration, presence, or streaming AI agent output. Covers product and SDK selection (Pub/Sub vs Chat vs Spaces vs LiveObjects vs AI Transport), authentication (JWT, token auth, authUrl), channel design, React integration, and critical mistakes like missing Chat attach(), client-side API key exposure, and creating Ably clients inside components. Fetches current docs from ably.com/llms.txt before generating code. Not for general WebSocket or non-Ably realtime libraries.
Reviews lyrics and prose for AI-written patterns (abstract noun stacking, over-explained metaphors, cliche escalation, missing idiosyncrasy, prose AI tells). Advisory Warning/Info severity — flags issues, does not block or rewrite. Use when reviewing lyrics for authenticity or before generation to catch AI-sounding language
Add or modify routes in the WooCommerce Store API (`/wc/store/v1/*`). Use when creating new Store API endpoints, modifying existing ones, or designing the schemas blocks and external integrations consume. Covers authentication, REST URL design, schema/response alignment, variation handling, idempotency, and common pitfalls
Scope a feature end to end and write an implementation spec under specs/ from an accepted proposal — current-system mapping, goals/non-goals, a Decision Log for one-way-door choices, a live Open Questions backlog, and a real migration + test plan. Read when asked to write a spec, scope this feature, turn this proposal into a spec, plan the implementation, or break this into tasks. Do NOT fire on frame a proposal or write the PRD (sibling frame-a-proposal — a PRD frames a change before it is accepted; this skill starts once one is), record a decision or write the ADR (record-a-decision), write a postmortem (write-a-postmortem), or review this design (review-a-design) — those are separate skills. Complements the platform open-knowledge skill; does not replace it.
Comprehensive spreadsheet creation, editing, and analysis with support for formulas, formatting, data analysis, and visualization. When Claude needs to work with spreadsheets (.xlsx, .xlsm, .csv, .tsv, etc) for (1) Creating new spreadsheets with formulas and formatting, (2) Reading or analyzing data, (3) Modify existing spreadsheets while preserving formulas, (4) Data analysis and visualization in spreadsheets, or (5) Recalculating formulas
When the user wants to set up, improve, or audit analytics tracking and measurement. Also use when the user mentions "set up tracking," "GA4," "Google Analytics," "conversion tracking," "event tracking," "UTM parameters," "tag manager," "GTM," "analytics implementation," or "tracking plan." For A/B test measurement, see ab-test-setup.
Build reliable third-party API integrations, including OAuth, webhooks, rate limiting, error handling, and data sync. Use when integrating external services (Slack, Stripe, Gmail, etc.), building API connections, handling webhooks, or implementing OAuth flows.
Brad Frost's Atomic Design methodology for UI component hierarchies: atoms (indivisible elements), molecules (small groups of atoms), organisms (complex sections of molecules), and templates (page layouts). Enforces bottom-up composition (never skip levels), presentational components (data via props, events via callbacks, no data fetching), design tokens for all visual properties, and composition over inheritance. Use when building user interfaces, creating component libraries, organizing frontend code, designing form systems, or structuring any UI. Triggers on: “build a component,” “component hierarchy,” “design tokens,” “presentational components,” “composition over inheritance,” “React/Vue/SwiftUI components,” “atomic design.” Applies to any UI framework.
Set up and maintain basic bookkeeping for a solopreneur business. Use when tracking income and expenses, preparing for taxes, managing invoices and receipts, understanding cash flow, or generating financial reports. Covers accounting software selection, chart of accounts, expense categorization, reconciliation, and financial statements. Not professional accounting advice — consult a CPA for complex situations. Trigger on “bookkeeping,” “accounting,” “track expenses,” “financial records,” “QuickBooks,” “invoicing,” “receipts,” “profit and loss”
Use a growth-stock framework to screen in bulk for strong stocks where earnings, expectations, relative strength, and supply-demand structure align, then output candidate tiers and key tracking points. Suitable for growth-stock hunting, trend-growth stock selection, and bulk scans of candidate pools.
Status dashboard for cheat-on-content. Shows the current mode / rubric version / calibration progress / items pending review / pool status / whether SQLite should be upgraded / whether the rubric should be bumped. Can be called at any time with no side effects. Trigger phrases: “状态”/“看板”/“status”/“我现在该做什么”/“进度怎么样”。
Create a complete, distinctive landing page for a product, event, marketing campaign, or brand using the city style library and optional interactive preview. Outputs HTML, CSS, JS, and SVG. Use when users request a visually expressive one-page website or explicitly ask to use citycraft. Not for ordinary dashboards, component fixes, static posters, or small maintenance tasks where brand design must not change; reuse existing product information and the user's chosen style when available.
This skill should be used when the user asks to "set up Cloudflare Queues", "create a message queue", "implement queue consumer", "process background jobs", "configure queue retry logic", "publish messages to queue", "implement dead letter queue", or encountering "queue timeout", "message retry", "throughput exceeded", "queue backlog" errors.
Project planning and management with CodeSpring. Use when the user wants to work with CodeSpring projects, tasks, PRDs, mindmaps, or analyze a codebase for project planning. Handles workspace selection, project linking, task management, and syncing findings to CodeSpring.
Chase a symptom to its true cause: reproduce it, shrink it, write falsifiable hypotheses, and prove the cause by toggling the symptom on and off, then hand over a failing reproduction instead of a fix. Use when the user says "debug this", "why is this failing", "find the root cause", "what's causing this bug", "this test is flaky", "it broke after the upgrade", "it worked yesterday", "this got slower", or "/debugkit".

Socratic coach for breaking down problems to fundamental truths. Use when users want to think through a problem deeply, challenge assumptions, or find innovative solutions. Triggers on requests like “help me think through this,” “let’s break this down,” “what are my blind spots,” “I’m stuck on a problem,” “challenge my assumptions,” or explicit requests for first-principles thinking.

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.
