Framework for writing data transformation models in SQL or Python, with a Terraform-like plan/apply flow, virtual data environments, unit tests and table diffs, and transpilation across 10+ SQL dialects. A Linux Foundation project and an alternative to dbt.

Guides the agent in writing library-grade Vue composables whose inputs accept a plain value, ref or getter: choose MaybeRefOrGetter or MaybeRef depending on whether the input is read-only or writable, and normalize with toValue() and toRef() inside watchers. Requires Vue 3 or Nuxt 3+.

For Vue 3 projects on the Options API (data(), methods, this): how to get TypeScript inference with defineComponent and type props, event handlers and computed values, plus gotchas like avoiding arrow functions in methods and lifecycle hooks and not sharing debounced state across instances.

Pinia best practices and gotchas for Vue apps: fixing the getActivePinia error, returning all state from setup stores, keeping reactivity when destructuring stores, calling store methods from templates, keeping ephemeral filters in the URL, and using Pinia in large apps.

Testing practices for Vue apps: Vitest and Vue Test Utils, black-box component tests, flushPromises for async code, helpers for testing composables, Pinia stores, async components and Teleport, avoiding snapshot-only tests, and Playwright for end-to-end testing.

Debugging index for Vue 3: maps common symptoms in reactivity, computed, watchers, components, props and emits, templates, forms and v-model, lifecycle, slots, TypeScript and SSR hydration to reference notes that explain the cause and the fix.

Vue Router 4 best practices and gotchas: guards and lifecycle hooks not firing when only params change, no this in beforeRouteEnter, async calls and infinite redirect loops in guards, the deprecated next() callback, and cleaning up listeners after unmount.

Default workflow for Vue work: standardizes on Vue 3, the Composition API and script setup with TypeScript, reads core references on reactivity, SFCs, data flow and composables, plans component boundaries first, loads topics like slots, transitions and performance only when needed, then self-checks.

Covers how JSX in Vue differs from React JSX, such as class instead of className and JSX plugin config, for migrating React JSX to Vue or fixing attribute type errors. A brief skill that points to a single reference note.

Lets agents read and write Figma: extract variables, components and styles, create and edit screens, FigJam boards and slides on the canvas, and run accessibility checks and design-system audits. Needs a Figma personal access token, the Figma desktop app, Node.js and the companion plugin.

Lets agents write and run Playwright scripts on the fly for browser automation: page tests, UX checks and multi-step flows, opening a visible browser by default and auto-detecting local dev servers. After installing the plugin, run npm run setup in the skill directory.
