Build curved-ray space effects in Three.js WebGPU/TSL. Use for artistic ray bending, Ellis wormholes, Schwarzschild black-hole lensing, accretion disks, physical thin-disk transport, or requests that need the Kerr/rotating-black-hole support boundary.
Apply visual effects to features including filters, drop shadows, blur, and grayscale. Use for highlighting features and creating visual emphasis.
Concurrency with Effect.all, forEach concurrency, Fiber lifecycle, race and timeouts. Use for parallelizing tasks safely.
Avoid unnecessary useEffect in React components. Most uses of useEffect are anti-patterns — derived state, event-driven logic, data fetching, and external store subscriptions all have better, more idiomatic alternatives. Apply this skill when writing or reviewing React components that use useEffect.
Implement reactive state management with Effect Atom for React applications
React useEffect best practices. Use when writing Effects, derived values, or data fetching. Teaches when NOT to use Effects and better alternatives like useMemo or key props.
For non-perishable things, future life expectancy is proportional to current age. Use for technology selection, evaluating frameworks/libraries, and predicting tool longevity.
Create and edit compositions, layers, animation, masks, and visual effects in the EffectCraft application through desktop control, MCP, or headless CLI. Use when the user asks to work in EffectCraft.
Scala resource lifecycle management with Cats Effect `Resource` and `IO`. Use when defining safe acquisition/release, composing resources (including parallel acquisition), or designing resource-safe APIs and cancellation behavior for files, streams, pools, clients, and background fibers.
This skill should be used when the user asks to "generate arbitrary values", "generate sample data from a schema", "use Effect Arbitrary", "Schema.toArbitrary", or to produce Effect Schema test data, fixtures, or FastCheck samples.
Build any of 16 premium motion effects from scratch in your own brand, as one 8-second looping HTML file with window.seek(seconds) so it exports frame-exact to MP4 or GIF. Interfaces (button to player, search to results, card to workspace, tabs to panels), data (chart morph, dashboard zoom, spring stack, magnetic dock), type (masked type, elastic type, text to layout, image reveal) and systems (perspective shift, glass focus, flowing paths, particle logo). Use when someone says "build the chart morph", "make a button that turns into a video player", "animate my logo with particles", "motion effect", "UI animation", "product animation", "animated dashboard", "kinetic type" or names any of the 16 effects.
Integrate and use argon-router in React web applications with Effector. Use when tasks involve creating routes and routers, wiring RouterControls/history adapters, composing routes with chainRoute/group/createVirtualRoute, rendering views with RouterProvider/createRoutesView/Outlet, building links with Link/useLink, and managing URL query state with trackQuery and @argon-router/paths.
