Advanced WeRead advisor. Built on the atomic APIs of the underlying weread skill, it provides four workflows: personalized advanced recommendations based on completed books (advisor), a progressive reading list from introductory to cutting-edge for a chosen topic (path), distilling scattered highlights into reading notes and summaries (alchemy), and quarterly or annual reading reviews with articles ready to post on social media or WeChat Official Accounts (review). Its core method is “cross-analysis of bookshelf and notes”—the bookshelf reveals interests users actively categorize, while notes reveal what they’ve actually read versus what they’ve only shelved. Trigger when users say “recommend a book,” “what should I read next,” “what should I read,” “I want to understand field X,” “organize my notes,” “what did I remember from this book,” “what did I read this year,” “reading review,” or “annual review.” Also trigger if they simply say “I don’t know what to read,” “any related books,” “help me check if I finished this book,” or “am I familiar with this field yet.”

Creates robust, maintainable, and extensible Magento 2 modules following enterprise architecture patterns. Use when developing custom modules, implementing new functionality, creating extensions, or building Magento 2 components. Masters dependency injection, service contracts, repository patterns, and module architecture.
Use when creating a new Make scenario or editing an existing one — finding modules, connections and account-dependent values, wiring the flow, saving through scenario_create or scenario_patch. Not for explaining, running or debugging a scenario, or for API-call shells.
Add a licensed soundtrack to any video for $0 with beat-matched music, Openverse sound effects, -16 LUFS mastering, and FFmpeg verification. Searches 5.2M free CC0/CC-BY/public-domain audio files (no API key), aligns cuts to the kick-drum beat grid with librosa, peak-normalizes SFX one-shots, verifies the exported MP4 with ebur128 and cue frame grabs, and auto-writes credits.txt. Trigger when the user says "add sound to this video", "add music to my video", "add sound effects", "find free SFX", "sound design this clip", "my video needs audio", or "add audio to my ad".
Code-reviews Pluggy API integrations against Pluggy's official documentation (queried in real time via the Pluggy MCP, with a web fallback to docs.pluggy.ai when the MCP isn't connected) and returns a diagnostic report (✅/❌/⚠️) with file, line, and the code fix for each issue. Use WHENEVER the dev uploads integration files and asks to review, analyze, diagnose, or validate their Pluggy integration — or says things like "review my integration", "check my Pluggy code", "is this ready for production?", "Pluggy Doctor", "check my webhooks", "is my integration secure?", or the Portuguese variants "analisa minha integração", "revisa meu código da Pluggy", "tá tudo certo pra ir pra produção?", "checa meus webhooks", "minha integração tá segura?". Also trigger when the dev pastes/uploads code that clearly calls the Pluggy API (connect_token, GET /items, item/created webhooks, clientUserId, etc.) and wants to know if it's correct, even without saying "Pluggy Doctor". This skill is for REVIEWING existing code, not writing an integration from scratch.
Use when recreating a trending reel, TikTok or Short with a different performer: the same dance, moves, timing and camera, performed by the user's own character from a reference sheet, optionally in another outfit or a redecorated room, keeping the original song in sync. Keywords: reel recast, trend remake, TikTok dance, replace the dancer, character swap, choreography transfer, video to video, keep the music, Seedance edit mode.
Maintain the official documentation for the Specsfy project itself in the promovaweb/specsfy monorepo. Use only at the official root when the request is to document Specsfy, reconcile cross-cutting changes, review docs/develop/context/, or update guides in docs/user/. Do not use in consumer projects; to rebuild an application's documentation, use specsfy-documentator.
Enterprise-grade access control patterns to prevent broken access control, IDOR, tenant data leaks, privilege escalation, and admin route exposure. Covers RBAC, ABAC, ownership checks, multi-tenant scoping, policy middleware, row-level security, and audit logging for Node.js, Cloudflare Workers, Laravel, and Python.

Design patterns for building autonomous coding agents. Covers tool integration, permission systems, browser automation, and human-in-the-loop workflows. Use when building AI agents, designing tool APIs, implementing permission systems, or creating autonomous coding assistants.
Fetches real, citable Bilibili (B站) video data — stats, metadata, tags, and full danmaku text — via login-free API calls, never hand-typed or estimated. Use when citing view/like/favorite counts, analyzing why a video performed, or archiving a Bilibili source into a knowledge base. Accepts BVID, av numbers, b23.tv links, or full URLs; subtitles and 收藏夹 (favorites) enumeration need the user's Bilibili login.
Core bioinformatics concepts including SAM/BAM format, AGP genome assembly format, sequencing technologies (Hi-C, HiFi, Illumina), quality metrics, and common data processing patterns. Essential for debugging alignment, filtering, pairing issues, and AGP coordinate validation.
Analyze Claude Code and Claude Desktop Code token usage, cost, quota burn, model mix, cache read/write, and 5-hour block consumption using ccusage evidence. Use when the user asks why Claude quota was exhausted, whether a model such as fable/opus/sonnet is unusually expensive, how many tokens were spent today or historically, or needs a human-friendly explanation of local Claude Code CLI/Desktop usage.

Use whenever the user wants to hand off to a fresh agent, is ending a session mid-task, asks for a handoff doc or a summary of state, decisions and next steps for the next session, or starts a new session that picks up prior work.

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.
