Reviews Svelte components for idiomatic patterns, identifies anti-patterns carried over from React/Vue/Svelte 4, and suggests Svelte 5 refactorings. Use when writing or reviewing Svelte components, asking "is this idiomatic", "Svelte way", doing Svelte 5 migration, or encountering smells like: effect assigns state, prop copied to $state, global store by default, $bindable everywhere, clickable div, createEventDispatcher, export let, on:click, slot-shaped APIs, lifecycle-driven code, imperative DOM wiring, immutable-update ceremony, context value replacement, shadcn-svelte form structure, Field.* components, bits-ui form controls, or component APIs that hide ownership. This is the general-purpose entry point for Svelte component review; delegates to sveltekit for routes/load/actions/server concerns and to focused references for details.
Use this skill when working with symbolic mathematics in Python. This skill should be used for symbolic computation tasks including solving equations algebraically, performing calculus operations (derivatives, integrals, limits), manipulating algebraic expressions, working with matrices symbolically, physics calculations, number theory problems, geometry computations, and generating executable code from mathematical expressions. Apply this skill when the user needs exact symbolic results rather than numerical approximations, or when working with mathematical formulas that contain variables and parameters.

Write Tailwind CSS following practices that keep a fast-to-write codebase maintainable — use design tokens instead of magic values, keep class lists short, group tokens semantically, generate classes in consistent order, avoid @apply for extracting repeated styles, and use fixed variants instead of arbitrary className props. Use this whenever writing or editing Tailwind classes, components, or config, and also when reviewing, cleaning up, refactoring, or auditing an existing Tailwind project. Do NOT use for general CSS architecture unrelated to Tailwind, or for build tooling unrelated to CSS output (bundlers, JS minification, etc.).
