datadog-labs Skill

Instrument browser-based web applications with Datadog Browser RUM. Detect the application framework, router, package manager, bundler, entrypoint, credentials, and existing RUM setup; add or safely complete classic Browser RUM instrumentation for React, Next.js App or Pages Router, Angular, Vue, Nuxt, Svelte, vanilla JavaScript, SPAs, and iframe-hosted apps; avoid duplicate initialization; and verify the application still builds.

gabrielmoreira Skill

Use Redis over HTTP from serverless and edge runtimes with @upstash/redis, and add rate limiting with @upstash/ratelimit. Use when the user mentions Upstash Redis, needs Redis from a Next.js route handler or middleware, Vercel, Cloudflare Workers, Deno, or Bun without TCP connection pooling, or wants cache-aside with TTLs, a session store, counters, or a 429 rate limiter using fixed window, sliding window, or token bucket. DO NOT use for self-hosted or TCP Redis clients (ioredis, node-redis), Redis Cluster administration, or vector similarity search.

kayforkind Skill

Implements frosted-glass panels via CSS backdrop-filter, SwiftUI ultraThinMaterial, Flutter BackdropFilter+ClipRRect, React Native BlurView, or Compose haze fallbacks. Use when the user wants glassmorphism, frosted glass, blurred translucent cards, or a macOS-like glass surface. Not for general layout/cascade (modern-css), Tailwind v4 scaffolding (setup-tailwind-typescript), or neumorphism. Never place glass on a solid white or black field — the effect vanishes.

Use when user mentions "accessibility", "a11y", "WCAG", "accessibility scan", "accessibility testing". Triggers on: "accessibility testing", "a11y scan", "WCAG compliance", "accessibility audit LambdaTest", "is my page accessible".

mastra-ai Skill

Tailwind CSS v4 usage guide and v3-to-v4 differences. This skill should be used when writing, reviewing, or refactoring any Tailwind CSS code in this repo. Triggers on tasks involving Tailwind classes, @theme blocks, CSS-first configuration, or cleanup of v3-era syntax.

nexu-io Skill

Wrap any HTML artifact with a side panel of live, parameterized controls — accent color, type scale, density, motion, theme — that rewrite CSS custom properties in real time and persist to localStorage. Lets the user explore variants of a design without re-prompting the agent. Use when the brief asks for "variants", "side-by-side options", "tweak this", "let me adjust", "live knobs", or "实时调参".

nrwl Skill

Update the CNW (create-nx-workspace) template repos (nrwl/empty-template, nrwl/react-template, etc.) to a target nx version via nx migrate, verify each repo, and open a PR per repo. Clones repos it needs - assumes no local checkout. Use when asked to "update the CNW templates", "migrate the templates to nx X", "bump the template repos", or given a version like "update templates to 23.2.0".

Render Codex, Claude Code, OpenClaw, or Pi session JSONL transcripts as a searchable, shareable single-file HTML viewer.

plannotator Bundle

Direct-invocation specialist for clear, self-contained HTML plans that preserve source material while improving hierarchy, sequence, ownership, dependencies, and reviewability. Use when the user explicitly invokes html-plan or the broad html skill routes a plan request here. Do not activate independently from a general request.

posthog Skill

Diagnose and fix React codebase health issues. Use when reviewing React code, fixing performance problems, auditing security, or improving code quality.

vercel Skill

Debug and verification workflow for runtime-bundle and module-resolution regressions. Use when diagnosing unexpected module inclusions, bundle size regressions, or CI failures related to NEXT_SKIP_ISOLATE, nft.json traces, or runtime bundle selection (module.compiled.js). Covers CI env mirroring, full stack traces via __NEXT_SHOW_IGNORE_LISTED, route trace inspection, and webpack stats diffing.

vercel Bundle

Benchmark React or Next.js changes on Vercel Sandbox VMs with paired A/B statistics: react PR/commit vs base, or Next.js PR/commit vs base, measured end-to-end through the bench/render-pipeline app (rps, latency, p95; TTFB, RSS and document/Flight bytes when the Next side captures them) and, for React changes, through the react repo's flight-ssr-bench fixture (Node AND Edge web-streams paths, Fizz and Flight+Fizz). Use whenever the user asks to bench, perf test, or A/B a React PR, a react-server-dom / Flight / vendored React change, or a Next.js PR ("is this PR faster", "does this regress RSC?", "measure the perf impact of <commit>"), even if they don't say "benchmark" — any request to quantify a server-side performance difference between two revisions belongs here. Runs remotely (laptop-free), applies correctness gates before measuring, and reports boot-level confidence intervals.

xuzhougeng Skill

Author a Wisp custom theme CSS file that uses documented tokens and import constraints. Use when the user wants a custom look, hide the paragraph lead bar, restyle chat Markdown, override colors, or import a stylesheet under Settings → Appearance.

Generates JSDoc-typed code with @typedef, @param, and @returns annotations for full type coverage without a TS compiler. Use when building Vue 3 applications with JavaScript only (no TypeScript), when projects require JSDoc-based type hints, when migrating from Vue 2 Options API to Composition API in JS, or when teams prefer vanilla JavaScript, .mjs modules, or need quick prototypes without TypeScript setup.

kayforkind Skill

Implements Mondrian-style color-blocking layouts with large flat geometric panels, a 3-4 color high-contrast palette, and thick black grid lines via CSS Grid or native stacks. Use when the user wants color blocking, Mondrian grids, or bold geometric color sections on web or mobile. Not for glassmorphism, VisionOS spatial glass, or gradient/shadow UI. Do not use as a general design-system or theming skill.

kayforkind Bundle

Embeds live Zoom meetings in a custom web container via Meeting SDK Component View (ZoomMtgEmbedded.createClient, Promise init/join, lowercase password). Use when integrating real Zoom meetings into React/Vue/Angular layouts with embeddable UI. Not for Zoom Video SDK custom sessions (ui-toolkit) and not for full-page callback-based Client View (passWord / #zmmtg-root).

kayforkind Skill

Generates multiple standalone HTML design explorations of one UI component, each in a different company design language, then adapts the winner into the real theme.

Not for implementing an already-specified restyle (hex/fonts/spacing), full-page redesigns, or design-system token architecture without exploration.

kayforkind Bundle

Debugs numerical parity between two ML pipeline implementations (research vs Diffusers, standard vs modular) with CPU/float32 component tests, encode/decode/denoise stage checkpoints, and tensor injection. Use when outputs look washed out, pixelated, or visually wrong, or when verifying a conversion. Not for training new models or general unit tests. Do not monkey-patch forward or mix reference code into the Diffusers path.

kayforkind Skill

Builds Remotion videos in React: compositions, useCurrentFrame, interpolate/spring, Sequence, and npx remotion render to MP4/WebM. Use when the user wants programmatic Remotion video, Remotion Studio, or frame-based React animation. Not for Premiere/FFmpeg timeline edits or AI video models (Sora/Veo). Never assume this folder ships a references pack.

kayforkind Skill

Builds end-to-end type-safe tRPC APIs: routers, Zod procedures, dual Next.js App Router context factories, protected middleware, and subscriptions. Use when scaffolding tRPC in a TypeScript monorepo or migrating REST/GraphQL incrementally inside one repo. Not for OpenAPI/REST-only backends or GraphQL schema-first stacks. Do not share one context factory between fetch Request handlers and RSC callers.

lobehub Skill

Use for splitting heavy domains into capabilities (原子组件) across page, portal, share or micro-app hosts, sinking state (状态下沉) and replacing mode/readOnly flags. Simple component splits: react.

mastra-ai Skill
