Build, revise, and debug Bayesian models with PyMC. Use when choosing likelihoods and priors, specifying model/data dimensions, fitting hierarchical models, GPs, time series, mixtures, BART or splines, selecting inference methods, resolving failed initial evaluation or model/data shape errors, generating predictions, or testing model code with simulated data and simulation-based calibration (SBC). Covers PyMC 6+, PyTensor 3+ and ArviZ 1.0 DataTree workflows.
Build GSAP motion without restyling, as single effects or the full treatment: for "we're animaxxing", every element enters from a blank page, rests, and leaves. Text: split, scramble, glitch, typewriter, and speak-in entrances, scattering headlines, letter waves, text on a path, count-ups, odometers. Scroll: reveals, scrubbing, parallax, pinned scenes, stacking cards, zoom-through, horizontal runs, waypoints, smooth scroll, paging. Pointer: magnetic, tilt, spotlights, directional fills, press ripples, shakes, cursor followers, image trails, proximity, label rolls, underlines. Drag: throw tracks, endless loops, card stacks, sortable lists, swipe to dismiss. Also page covers, Flip and shared-element morphs, menus, dialogs, tabs, state buttons, media and SVG effects, marquees, CustomEase, sound, confetti, particles, and hover stuck on touch. Pair with the matching GSAP framework skill. Not for branding, redesign, routing, or GSAP API questions.
Measure how many hours a person really works per day, per client or project, and at what clock times, from the digital exhaust they already leave — Claude Code transcripts, Slack, WhatsApp, meeting recordings, laptop screen time, browser history and chess games — with leisure subtracted and the idle threshold calibrated against their own stated breaks. Use it whenever someone asks "how many hours do I actually work", "how much time do I spend on client X vs Y", "what are my working hours / routine", "am I overworking", "how much of my day is chess / YouTube", or wants a timesheet reconstructed after the fact. Trigger it even when the word "hours" never appears — "how long are my days", "split my time between customers", "when do I usually start and stop" are this skill.
Use for real projects that combine a Next.js frontend/BFF with a NestJS API. Covers ownership boundaries, OpenAPI client generation, session and auth propagation, CORS/proxy contracts, Server Component data fetching, shared environment contracts, and split deployment/runtime alignment.
Browse, search, read, and inspect files in the IBM i Integrated File System (IFS) including authorities, locks, and server shares. Use when user asks about: (1) listing IFS directory contents, (2) searching for files by name or pattern, (3) reading text file contents, (4) checking file authorities or permissions, (5) diagnosing file lock contention, (6) finding large files consuming disk space, (7) viewing NetServer file shares, or (8) replacing WRKLNK, DSPAUT, DSPLNK command output.
Plan paid acquisition tests from Traction across SEM, social/display ads, and offline ads. Use when designing ad experiments, keyword tests, audience tests, paid channel budgets, or deciding whether a paid channel can acquire the right customers profitably.
What ACE Studio's features are and when to reach for each one — track types and what makes sound on them, audio effects, Vocal Synth and its voice library, AI Instruments, third-party instrument plugins, the generative kits (Inspire Me, Music Enhancer, Add A Layer), and the utilities (Stem Splitter, Voice Changer, Vocal to MIDI, Doubles, marker track, file import). Load whenever the user wants to create, change or understand anything in ACE Studio: adding a voice or instrument, choosing a singer, generating music, splitting stems, converting a vocal, or asking what a feature does. Pair with `ace-studio-workflows` for the order to do things in.
Apple Human Interface Guidelines interaction and UX patterns. Use this skill when the user asks about "onboarding flow", "user onboarding", "app launch", "loading state", "drag and drop", "search pattern", "settings design", "notifications", "modality", "multitasking", "feedback pattern", "haptics", "undo redo", "file management", data entry, sharing, collaboration, full screen, audio, video, haptic feedback, ratings, printing, help, or account management in Apple apps. Also use when the user says "how should onboarding work", "my app takes too long to load", "should I use a modal here", "how do I handle errors", "when should I ask for permissions", "how to show progress", or "what's the right way to confirm a delete". Cross-references: hig-foundations for underlying principles, hig-platforms for platform specifics, hig-components-layout for navigation, hig-components-content for data display.
When the user needs to handle competitive situations in sales conversations. Also use when the user mentions 'competitive deal,' 'against [competitor],' 'battlecard,' 'competitive positioning,' 'how to beat [competitor],' 'displacement deal,' or 'competitive objection.' Covers competitive intelligence, battlecards, positioning strategies, and winning against specific competitors.
Use when adding, moving, or removing images, sprites, text, or video on the Pixi'VN game canvas, or when applying or creating transitions (dissolve, fade, move, zoom, push, wipe, iris, split, flash, blur, pixelate, or a custom one built on `canvas.animate`/`filters.animate`), shake/animation effects, or ticker-based animations built on PixiJS. Covers the `canvas` singleton exported from `@drincs/pixi-vn`. For UI layers (HTML or PixiJS) mounted on top of the canvas, see `pixi-vn-ui` instead.
Adapt a Flutter app to iPhone Duo, Apple's first foldable iPhone — what MediaQuery gives you today, why displayFeatures does not work here, and how to bridge the iOS 27.1 reserved-region, hinge and arrangement APIs through platform channels. Use when a Flutter or Dart app needs foldable iPhone support.
Enforces a fixed main() cold-launch order — crash-log sink + FlutterError.onError + PlatformDispatcher.onError installed BEFORE any code that can throw, settings/theme read before runApp so the first frame paints correct, real infra constructed in a composition-root bootstrap() and injected via ProviderScope overrideWithValue over throwing placeholder providers, non-blocking warm-up deferred to addPostFrameCallback, exactly two error handlers with NO runZonedGuarded, ProviderException unwrapped before logging, and a WidgetsBindingObserver that flushes durable state on background/resume. Use when editing lib/main.dart, main_<flavor>.dart, bootstrap.dart or app.dart, reordering anything in main(), adding a splash/onboarding/permission gate, restoring theme before first paint, wiring a DB or service into ProviderScope, handling app-lifecycle background/resume flushes, or chasing cold-start latency, ANRs, or first-frame jank.
