Enumerates virtual chemical libraries via reaction SMARTS transformations using RDKit and Reaction templates, with explicit handling of atom mapping, template extraction (RDKit reaction mining), product validation, RECAP/BRICS fragmentation, R-group decomposition, matched molecular pair analysis (MMPA), and Free-Wilson analysis. Use when generating combinatorial libraries from building blocks, enumerating analog series, deriving structure-activity rules, or extracting transformations from reaction data.

Research recent X/Twitter reactions to markets, companies, products, or communities. Produce a reusable Markdown briefing that groups supportive, critical, and neutral views, with citations, coverage details, and an assessment of overall sentiment.
Build and review web animations with GSAP's core API, including movement, rotation, fades, and staggered starts. Adjust timing and easing, meaning changes in speed, and adapt animations to screen size and reduced-motion preferences.
Builds and improves web interfaces, covering layout, styling, motion, and usability. It records design rules before implementation, uses supplied references or design research, and checks the result in real browsers for visual consistency, accessibility, and performance.
Migrate existing Remotion video compositions to HyperFrames HTML and GSAP. Checks source code for unsupported patterns, maps animation and media features, compares rendered videos for visual similarity, and documents translation gaps.
Build custom interactive charts, network diagrams, and maps with d3.js. Guides data-driven drawing, tooltips, zooming, animation, responsive sizing, and accessibility, with examples that work in plain JavaScript or frameworks such as React, Vue, and Svelte.
Build reusable interface components with Tailwind CSS v4, using shared design values for colors, corners, and themes. Covers buttons, forms, responsive layouts, accessibility, and dark mode to help standardize interfaces across a project.
Guide cross-platform app development with Avalonia UI and Zafiro using consistent architecture and coding conventions. Keep screen logic separate from UI dependencies, handle errors explicitly, and reuse existing helpers with ReactiveUI and DynamicData.
Test app interfaces on an Android emulator using ADB, a command-line device tool. Inspect element positions, perform taps and text entry, then check screenshots and React Native logs to verify behavior and investigate layout or interaction bugs.
