Manage dotfiles with chezmoi — the source-state dotfile manager that uses filename attributes (`dot_`, `private_`, `encrypted_`, `run_once_`), Go templates, and password-manager integration to keep one set of dotfiles working across many machines. Use when the user says "set up dotfiles", "manage my dotfiles", "bootstrap a new machine", "chezmoi", "encrypt my SSH key in dotfiles", "template dotfiles per OS", "add secrets to dotfiles", "what should be in my .chezmoi.toml.tmpl", or asks how to share configs across macOS / Linux / servers. Also trigger when the user is staring at a fresh machine and wants the one-liner that gets them home, or when they're about to commit something sensitive into a dotfiles repo. Do NOT use for stow / yadm / rcm or other dotfile managers, generic git repo setup, or password-manager setup unrelated to dotfiles.
Design and build polished web UI in Tailwind v4, or rescue a screen that looks messy, generic, or unfinished. Use when an interface should look gorgeous. Not for page directions (`maquette`), app shells (`armature`), screen sizes (`reflow`), Paper mockups (`paste-up`), or QA (`fieldtest`).
Query the Chinese classical poetry API service (chinese-poetry-api, repo: https://github.com/palemoky/chinese-poetry-api) — 370k+ poems from Tang/Song/Yuan dynasties, with authors, dynasties, poetry types, full-text search, and random poem drawing. Use whenever the user asks to look up, search, or list classical Chinese poetry (古诗/唐诗/宋词/元曲), a specific poet's works, random poems, 飞花令 (single-character draws), or poetry metadata — even casual queries like "帮我找一首李白的诗" or "来一首五言绝句". Covers every REST endpoint: health, stats, poems (filtered lists), search, random, authors, dynasties, types. All output is raw server JSON, passed through unchanged.
Build a premium cinematic landing page with mouse-scrub video hero and brand-driven narrative-arc sections. Use whenever the user provides a hero video plus a product / subject / brand and wants a landing page, promo site, product showcase, marketing page, or storytelling site. Works for any language (RTL or LTR — Hebrew, English, Arabic, Spanish, French, Japanese, etc.) and any subject (food, tech, animals, fashion, services, SaaS, wildlife campaigns, music releases, books, real estate). The signature effect is mouse-driven video scrubbing — the hero video lives across the entire page as a fixed backdrop, and moving the mouse left-right scrubs the video timeline so the subject responds to the cursor. Below the hero, 4-5 fully-opaque sections each carry their own brand identity (color, typography emphasis, layout pattern) and walk the viewer through a narrative arc (e.g. longing → joy → nostalgia → contemplation → action). Triggers on phrases like "build a landing page from this video", "cinematic landing page", "mouse scrub hero", "video that follows the cursor", "Apple-style premium product page", "the baby video scrub thing", "narrative landing page", "scrubable hero", "golden landing template", "make a promo site for this brand", "build me a showcase page with this clip". Do NOT use for parallax frame-scrub landings where the page itself doesn't scroll (use `parallax-landing-page` instead) or for video editing / captioning workflows (use `video-edit`).
This skill should be used when the user is building, planning, or strategizing and the key question is whether to optimize content (what) or change form (how/medium).

Applies Alan Kay's metamedium concept to surface form-level alternatives. For requirement clarification use vague; for strategy blind spots use unknown.
This skill should be used when the user provides a strategy, plan, or decision document and wants to surface hidden assumptions and blind spots using the Known/Unknown 4-quadrant framework. Trigger on "known unknown", "4분면 분석", "blind spots", "뭘 놓치고 있지", "뭘 모르는지 모르겠어", "전략 점검", "전략 분석", "assumption check", "가정 점검", "quadrant analysis", "what am I missing". Strategy-level blind spot analysis with hypothesis-driven questioning. For requirement clarification use vague; for content-vs-form reframing use metamedium.

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.
