Best practices for linking tools to interactive frontend widgets using @Widget and @nitrostack/widgets SDK (including state sync, tool calling, display modes, media queries, and chat actions).

astriaai Skill

Use when editing, updating, or iterating on a workspace's landing page HTML (the magazine-style /w/:slug page). Supports incremental edits — fetch the current HTML, make targeted changes, then write it back. NOT for initial generation — that comes from the `brief` field which runs the server-side LANDING_PAGE_PROMPT against Gemini.

lufigir Bundle

Scan a codebase for deepening opportunities, present them as a visual HTML report, then grill through whichever one you pick.

marmelab Skill

Coding practices for frontend development in Atomic CRM. Use when creating or modifying React components, forms, list pages, detail views, filters, data fetching, or responsive layouts.

marmelab Skill

Shadcn/ui theming and component customization — CSS variables, OKLCH colors, dark mode, variants, wrappers. Load for any ticket involving colors, theme, UI layout, or component styling.

mj-deving Skill

Amplify safe or boring designs to make them more visually interesting and stimulating. Increases impact while maintaining usability. Use when the user says the design looks bland, generic, too safe, lacks personality, or wants more visual impact and character.

mj-deving Skill

Review a feature and enhance it with purposeful animations, micro-interactions, and motion effects that improve usability and delight. Use when the user mentions adding animation, transitions, micro-interactions, motion design, hover effects, or making the UI feel more alive.

mj-deving Skill

Add moments of joy, personality, and unexpected touches that make interfaces memorable and enjoyable to use. Elevates functional to delightful. Use when the user asks to add polish, personality, animations, micro-interactions, delight, or make an interface feel fun or memorable.

mj-deving Skill

Strip designs to their essence by removing unnecessary complexity. Great design is simple, powerful, and clean. Use when the user asks to simplify, declutter, reduce noise, remove elements, or make a UI cleaner and more focused.

mj-deving Skill

Add strategic color to features that are too monochromatic or lack visual interest, making interfaces more engaging and expressive. Use when the user mentions the design looking gray, dull, lacking warmth, needing more color, or wanting a more vibrant or expressive palette.

mj-deving Skill

Pushes interfaces past conventional limits with technically ambitious implementations — shaders, spring physics, scroll-driven reveals, 60fps animations. Use when the user wants to wow, impress, go all-out, or make something that feels extraordinary.

octanejs Skill

Find and fix a bug in the octane monorepo. Use when given a failing test, a regression, or a report that behavior differs from expectation, including deciding whether a React mismatch is an intentional divergence.

octanejs Skill

Write a new Octane component in .tsrx, convert JSX to .tsrx, or add scoped <style> blocks and themes. Use when creating a .tsrx file rather than editing one, because the path-scoped tsrx-authoring rule only fires once such a file is open.

octanejs Skill

Compatibility entry point for React-library work in Octane; routes existing-binding maintenance to update-bindings and actual React implementation ports to octane-react-library-port.

octanejs Bundle

Implement and verify new React-library ports or copied/rewritten React surfaces in Octane bindings from npm names or npm/GitHub links/lists. Enforces immutable provenance, license boundaries, dependency ordering, full-surface parity, and machine evidence. Existing-binding audits and maintenance start with update-bindings.

paddlehq Skill

Receive and verify Paddle webhooks in a Next.js Route Handler — signature verification, idempotency, retry semantics, and local testing.

paddlehq Skill

Add a Paddle Checkout to a Next.js web app — overlay or inline, with event handling, customer pre-fill, and dynamic line item updates.

paddlehq Skill

Render country-localized prices on a Next.js pricing page using Paddle.js PricePreview — country detection, billing frequency toggle, and currency formatting.

paddlehq Skill

Render the authenticated user's billing history in Next.js — listing transactions via the Paddle Node SDK, the mandatory customer-id filter, pagination via `.next()`/`.hasMore`, status filtering, and formatting raw transaction totals (lowest-unit conversion + Intl.NumberFormat, with the zero-decimal currency special case for JPY/KRW/CLP).

paddlehq Skill

Mint a Paddle customer portal session URL from a Next.js Server Action — the portal-vs-custom-billing-screen trade-off, auth, ownership, URL structure (overview vs deep links), and the security model.

paddlehq Skill

Cancel a Paddle subscription from a Next.js Server Action — auth, ownership check, safe `effectiveFrom` default, revalidation, and the `canceled` vs `scheduledChange` distinction.

paddlehq Skill

Change a Paddle subscription's plan from a Next.js Server Action — auth, ownership check, `prorationBillingMode`, items-array replace semantics, preview-before-commit, and `on_payment_failure` handling.

pmndrs Bundle

TypeGPU is type-safe WebGPU in TypeScript. Use whenever the user writes, debugs, or designs TypeGPU code: 'use gpu' shader functions, tgpu.fn, buffers, textures, bind groups, compute and render pipelines, command encoders, render passes, render bundles, vertex layouts, slots, accessors, @typegpu/react hooks (useRoot, useFrame, useUniform), React Native worklet rendering, and any TypeGPU API. Shader logic and CPU-side resources are tightly coupled - handle both sides here even if the user only mentions one (e.g. "how do I write a shader", "how do I create a buffer"). Trigger on any mention of typegpu, tgpu, "use gpu", TypedGPU, or WebGPU code written using TypeGPU's schema API (d.*, tgpu.*, std.*). Do NOT trigger for raw WebGPU (using GPUDevice/GPURenderPipeline directly without tgpu), WGSL-only questions, Three.js, Babylon.js, or WebGL.

research-ag Skill

Add `///` doc strings to public objects in Motoko modules so that `mo-doc` produces useful HTML/Markdown documentation. Covers placement rules, formatting, code examples, common pitfalls, and a verification workflow.

saffron-health Skill

Create a visual explanation of the current session diff as a single HTML page and show it in a native Glimpse window. Use when the user wants a visual walkthrough of local code changes instead of a plain text diff.

shakacode Skill

Orchestrate a destructive demo-workspace QA stress test for React on Rails leakage, memory, performance, security, and framework edge cases. Use only when the user explicitly asks to run stress testing.

shakacode Skill

Use when adopting React Server Components in a React on Rails Pro app, including prerequisites, generator setup, component boundaries, data flow, and safety checks.

shakacode Skill

Use when diagnosing a React on Rails app with the stable doctor JSON contract and iterating through actionable remediation until no error-level checks remain.

shakacode Skill

Use when a React on Rails Pro streaming SSR or async-props response buffers, stalls, fails to reveal Suspense content, or behaves differently behind a proxy.

shakacode Skill

Use when installing React on Rails into an existing Rails app or upgrading its gem, npm package, generated configuration, and lockfiles without version skew.

stark-ai-de Bundle

Set up repository-native ADR governance, audit architecture, or plan and execute ADR-guided refactors through intent-bound workflows. Use when work needs binding agent-facing ADRs, provider-to-local mapping, architecture PR review or drift, Next.js request patterns, source placement, backend/runtime/env/config boundaries, stack deviations, or bounded ADR-governed implementation. Do not use for tiny edits, generic framework education, or work with no architecture or governance consequence.
