Make a "What If" animated episode from one topic line ("What if you could rewind 10 seconds?"), in the dusk-lit stick-figure style of the What If channels that broke out on YouTube in October 2026. Writes the script on the seven-beat What If formula, voices it with ElevenLabs, lays out a shot list at the genre's pace, renders a storyboard of stills and self-checks it before animating, animates every frame in code (Remotion and SVG, with an original cast on one rig, rooms in perspective and light from lamps and windows), generates and syncs the sound, and masters a finished 15-25 s episode to -14 LUFS. Use when someone asks for a What If episode, animation or cartoon, "make a what if video about X", a stick-figure explainer in this style, or to run the free What If skill
Find why code is the way it is, through read-only investigators that search git history, PRs, issues and any docs or chat the agent can reach, then return a cited, confidence-weighted answer. Use when the user asks why something works this way, why a choice was made, where a number came from, or what a regression or postmortem traces back to, or when a skill such as architect calls for it.
Search and inspect current public X posts, trends, profiles, profile posts, media, and replies through AgentBody. Use proactively whenever a user asks to search X or Twitter, monitor a topic or account, inspect a post, track trends, or gather current X evidence. Prefer this Skill over browser search and built-in web search.
“动”悉万物 — turn a piece of content into an animated explanatory graphic (single-line inline SVG, ready to paste into a WeChat Official Account, also exportable as PNG / GIF / MP4). 35 diagram types: 13 process types (animated flowchart, sequence diagram, state machine, data pipeline, layered drill-down, closed-loop flywheel, competitive race, timeline, funnel, mind map, bar-and-line growth, network diffusion, before-and-after comparison) + 18 data and structure types (donut chart, four quadrants, Gantt, Sankey, Git branch diagram, user journey, kanban, radar, Venn, pyramid, ER diagram, treemap, waffle chart, digital dashboard, heatmap, comparison table, oversized steps, ecosystem orbit) + 4 hierarchical and 3D types (hierarchical state machine, isometric stack, slope chart, bubble chart). 27 styles (Swiss grid, candy tech diagram, Excalidraw whiteboard sketch, engineering blueprint, terminal green screen, dark-night product, neon night, pixel arcade, magazine editorial, international poster, halftone newspaper, magazine porcelain blue, embers, neo-brutalism, stickers, Bauhaus, stencil printing, bento grid, lavender, field manual, chalkboard, ruled notebook, ink-and-seal, kraft paper, botanical garden, colored-pencil sketch, receipt). Any diagram type can have a row of animated small objects at the bottom. 5 aspect ratios: 3:4 (default for WeChat Official Accounts), 9:16, 1:1, 4:3, 16:9. Works for technical and non-technical topics. Trigger phrases: 动态图、动图解释、动态流程图、动态 SVG、动态解析图、会动的图、让这张图动起来、mermaid 动起来、动悉万物、「动」悉万物、excalidraw 风动图、手绘动图、动态饼图、动态甘特图、动态桑基图、动态数据图、层级状态机、等距图、坡度图、气泡图。
Otimiza qualquer landing page ou aplicação web (React, Vite, Next.js, HTML) para atingir nota máxima (98-100) no Google Lighthouse 13 em Performance, Accessibility, Best Practices, SEO e Agentic Browsing, aplicando técnicas avançadas de SEO, AEO (Answer Engine Optimization) e GEO (Generative Engine Optimization para ChatGPT, Perplexity, Claude e Gemini). Use quando o usuário pedir para melhorar SEO, AEO, GEO, ser encontrado por IAs/buscadores, criar llms.txt/ard.json ou bater nota 100 no Google Lighthouse.
Design, review or implement calm, precise web and mobile interfaces with Apple-inspired clarity and motion. Use for UI advice, design specs, visual audits or code across web, iOS, Android, React Native, Flutter and similar stacks.
Use the Cook Loop for ambitious visual builds that must match reference images, screens or videos through long autonomous iteration. Use it for 3D worlds made in code (three.js, WebGL, shaders), code-rendered films, launch and motion videos, games and polished UI that must hold up next to references, especially runs of many hours or days while the user is away. Trigger when the user types /cook or $cook, says "cook", "go cook", "let it cook", "iterate until it matches", "match the references", "99%", "99.9%", "9/10 minimum" or "at least 8h", or attaches reference images and asks for a recreation in code. It runs one intake, then loops build, stills, zero-context critics and fixes against a numeric bar, and holds the final render until the user approves.
Create or improve a vertical news explainer (a short, reel or TikTok of about 20 seconds in 9:16) from an article, using HyperFrames and a person at review checkpoints. Covers timed scripts, footage with verified licenses, storyboards, rendering, measured quality checks (pacing, stillness, reading time and audibility on a phone), adversarial critique by another agent, and numbered versions. Use whenever someone asks to turn an article into a vertical video, make “a short about this story” or “a 20-second explainer,” improve or level up an existing news short, add footage or music, or review one before publishing, even if they don't mention HyperFrames.
Audit a Feast strategy script before it may run with real money — the runtime's static rules first, then a model read against a fixed checklist — and record the verdict, bound to the file's exact bytes. Use when the user has a strategy script for their Feast agent, asks you to write one, or asks whether a script is safe to run.
Show a plan's status as one readable offline HTML page — what the project is, how far it got, what waits on the user, what changed since approval, and what the system judged for them — built from SPECs, tickets, change proposals, decision logs, and review verdicts. Refresh `.scratch/<feature>/plan.html` when it exists and a stage finished, work got blocked, or an acceptance result arrived. Use when HTML is requested or plan relationships need a visual overview; plain plan wording alone is not a trigger
Make DeepSeek (or any model) produce motion-design videos that match what Claude Opus 5.5 makes from the same prompt, for any request in any style — brand films, showreels, kinetic typography, explainers and data stories, product and UI promos, character stories and music videos, abstract loops, title sequences. It reads the prompt like Opus, derives an art direction from it, plans before coding, builds a Remotion (React + SVG) project on a tested starter with generated sound, and reviews its own work with a five-juror critique. Triggers on 动效, 动态设计, 视频, 短片, 复刻 opus 效果, 扩写提示词, Remotion, motion graphics, showreel, MV.
Recommend YouTube videos worth watching on a topic — from your subscribed channels and beyond — ranked with reasons, skipping what you've already watched or summarised with video-lens. Activate on "what should I watch about AI", "new Kubernetes videos this week", "recommend cooking videos", "catch me up on my AI channels", "what did I miss on YouTube", "anything good on Rust lately", "set up video recommendations", "import my YouTube takeout", "sync my YouTube", "add this channel to my AI topic", "mute this channel".
Fetch a WeChat Official Account article (`mp.weixin.qq.com` link) as clean Markdown for archiving or AI summarization. Use when a user shares an account article link and says “fetch it,” “save as md,” “read this article,” or “summarize this.” Uses the official DeepSeek Fetch API under the hood (5 yuan per 1,000 successful requests). Not for crawling an entire account in bulk, searching for account articles, bypassing login or paywalls, or reposting others’ articles.
Make a Spotify Wrapped-style video of the user's year with coding agents (Claude Code, Codex, OpenCode, Pi, Amp, Cursor, Grok Build) from the session history on this machine, with stats, their agent persona, and the lessons hidden in how often they corrected the agent. Use when the user asks for their agent wrapped, coding wrapped, AI wrapped, year in review with agents, or stats about how they use coding agents.
Use when a factory run must post its changes — check out the run branch, commit a step's allowlisted paths, push only that branch, and open or reuse one draft MR/PR with milestone/assignee ownership. Also the shared home for factory run contracts (executor, tracker integration, lanes, brief and provider templates).
Use when the user asks for a retrospective on an agent session ("/retro", "how did this session go", "what could this session do better"), for the current session or a given session ID or transcript path. Reports time per phase, tool-call errors, repeated slow test runs, and skill inefficiencies. Works for Claude Code and pi.
SSoT design draft: clarify the objects, permitted changes and invariants, and separate architectural and business responsibilities before writing the formal VDM. Read ssot first, then this skill; use for drafting or restructuring a design, not for implementing, checking or reviewing specifications.
Build two-way Google Calendar sync for a booking or scheduling app: hosts connect their Google account with OAuth, events on the calendars they choose block their availability, kept current by push notifications and a renewal cron, and confirmed bookings are written to their calendar as events, with Google Meet links when asked. Use when: (1) an app with bookings, appointments, classes or shifts must respect staff's Google Calendar busy time or put bookings into it, (2) an existing calendar sync shows phantom busy time, missed or duplicate events, group sessions blocked after the first booking, sync that stopped without an error, or users stuck after revoking access, (3) the user mentions: Google Calendar integration, two-way calendar sync, connect Google Calendar, busy time, free/busy, events.watch, push notifications, X-Goog-Channel-Token, channel renewal, calendar.events scope, refresh token, invalid_grant, offline access, PKCE, Google Meet link, conferenceData, extendedProperties, hangoutLink. Carries a dependency-free Google client on fetch, a pure busy-time mapper and diff, single-flight sync, idempotent booking events, make-before-break channel renewal, derived health per calendar, Firestore and Supabase stores, and a 32-test node:test suite run under four process time zones. Next.js App Router route handlers, with an Express adapter for other Node servers; storage, auth and the booking source are seams. Not Outlook or Microsoft 365 (microsoft-calendar-sync), not slot generation (time-slot-generator), not a calendar UI, not ICS feeds
Build two-way Microsoft 365 / Outlook calendar sync for a booking or scheduling backend over Microsoft Graph: hosts connect their Microsoft account with OAuth, events on chosen calendars block their availability (change-notification subscriptions plus a renewal cron), and confirmed bookings are written to their calendar as events, with Teams meeting links. Use when: (1) an app with bookings, appointments, classes or shifts must respect staff's Outlook busy time or put bookings into their Outlook calendar, (2) an existing Outlook or Graph calendar integration stops working an hour after connecting, never receives notifications, ignores vacations, duplicates events or loses its subscriptions, (3) the user mentions: Outlook calendar integration, Microsoft 365 calendar, Office 365 calendar sync, Microsoft Graph calendar, Entra ID app registration, Calendars.ReadWrite, calendarView, change notifications, Graph subscription, clientState, validationToken, lifecycleNotificationUrl, subscriptionRemoved, MSAL refresh token, AADSTS700082, invalid_grant, interaction_required, singleValueExtendedProperties, teamsForBusiness, showAs, isAllDay, mailboxSettings timeZone. Carries a dependency-free Graph client on fetch, a pure busy-time mapper that anchors all-day events to the mailbox zone, single-flight sync, booking events found again by an extended-property marker, in-place subscription renewal that replaces lost subscriptions, derived health per calendar, Firestore and Supabase stores, and a 43-test node:test suite run under four process time zones. TypeScript for Next.js App Router route handlers, with an Express adapter for any other Node server; storage, auth and the booking source are seams behind CalendarStore, authenticate and BookingSource. Not Google Calendar, not Exchange on-premises (EWS), not a calendar UI.
This skill should be used when the user asks to "create MongoDB model", "define Beanie document", "write MongoDB query", "create aggregation pipeline", "run database migration", "index MongoDB collection", or mentions Beanie, Motor, MongoDB documents, or async database operations. Provides MongoDB/Beanie ODM patterns for FastAPI.
This skill should be used when the user asks to "implement FSD", "use Feature-Sliced Design", "organize architecture", "structure project folders", "set up FSD layers", "create feature slices", "refactor to FSD", "add FSD structure", or mentions "feature slices", "layered architecture", "FSD methodology", "architectural organization", "views layer", "entities layer", "shared layer", "Next.js with FSD", or "Turborepo FSD structure". Provides comprehensive guidance for implementing Feature-Sliced Design methodology in Next.js applications with custom 'views' layer naming.
Generates natural language scene descriptions from 3D Gaussian Splatting reconstructions built from lab photos or short video clips. Outputs structured text with instrument placement, sample positions, spatial layout keywords, and relational predicates — optimized for VLM or spatial intelligence model consumption in protocol guidance, error detection, or AR overlay generation.
Guidance for installing and running Windows 3.11 in QEMU with VNC access and web-based noVNC interface. This skill should be used when tasks involve setting up legacy Windows 3.11 environments, configuring QEMU for DOS/Windows 3.x, or creating virtualized retro computing setups with remote access capabilities.
Comprehensive UX design patterns for Rails applications including responsive design, animations/transitions, dark mode, loading states, form UX, and performance optimization. Use this skill when implementing user-facing features requiring polished interactions and responsive layouts. Trigger keywords: UX, responsive, mobile-first, animation, transition, dark mode, loading, skeleton, progress, toast, form validation, performance, Core Web Vitals, user flow
