Web & Frontend

kayforkind Skill

Lays out Apple-style bento grids: mixed-span rounded compartments (1x1, 2x1, 1x2, 2x2) with CSS Grid, Flutter staggered tiles, SwiftUI LazyVGrid, or RN/Compose row stacks. Use when the request is a bento grid, bento-box dashboard, or modular compartment cards. Not for plain card lists, Flexbox-only galleries, or magazine masonry that skips equal-gap compartments.

kayforkind Skill

Manages Vercel/Next.js environment variables: .env load order, vercel env pull/add/ls/rm, VERCEL_OIDC_TOKEN (~12h local), and production/preview/development scoping. Use when editing .env.local, running vercel env, or debugging expired OIDC on a linked project. Not for Netlify env (netlify-cli-and-deploy), Wrangler secrets, or dotenv without Vercel. Never put secrets on NEXT_PUBLIC_ keys; vercel env pull replaces the whole file.

kayforkind Skill

Applies fp-ts in React 18/19 and Next.js 14/15: Option state, Either form validation, TaskEither fetches, RemoteData UI, and React 19 use/useActionState/useOptimistic with functional patterns. Use when building React apps that already use or should adopt fp-ts instead of null flags. Not for Redux or Zustand without fp-ts, or category-theory lectures with no UI code.

kid-sid Bundle

open-gsd Skill

Retroactive 6-pillar visual audit of implemented frontend code

plannotator Bundle

Create or redesign self-contained single-file HTML artifacts with a visual direction shaped by the user's brief, project, and subject. Use when HTML is the deliverable for a report, explainer, landing page, presentation, tool, mixed artifact, or broad request. This is the collection's only implicit router. Route clear wireframe, prototype, mockup, plan, or diagram requests to the matching direct-invocation specialist when available. Do not use for ordinary application implementation when a standalone HTML file is not the deliverable.

posthog Bundle

Multi-agent QA review team for code changes. This skill should be used when the user asks to "review my code", "run QA", "qa-team", "review this branch", "code review", "check my changes", or wants a comprehensive multi-perspective code review of the current branch's changes. Spawns parallel specialist agents (security, database, reliability, compatibility, data integrity, performance, frontend, copy) that independently review the diff and produce a converged report. Also includes two generalist reviewers for convergence validation.

simstudioai Skill

Run all code quality skills — effects, memo, callbacks, state, React Query, emcn design review, url-state, and comments — analyzing in parallel, then applying fixes sequentially

vercel Skill

DCE-safe require() patterns and edge runtime constraints. Use when writing conditional require() calls, guarding Node-only imports (node:stream etc.), or editing define-env-plugin.ts / app-render / stream-utils for edge builds. Covers if/else branching for webpack DCE, TypeScript definite assignment, the NEXT_RUNTIME vs real feature flag distinction, and forcing flags false for edge in define-env.ts.

vercel Bundle

Manages stacked PRs and splits multi-part work into reviewable branches with gh-stack. Use for stack creation, viewing, edits, push, submit, sync, rebase, merge, or checkout; when asked to split or isolate work for review; whenever a user mentions a stack, branch layers, dependent PRs, or gh stack; or when a stack is checked out.

Use this skill when the user says "export wiki", "export graph", "export to JSON", "export to Gephi", "export to Neo4j", "export to Postgres", "export to SQL", "graphml", "visualize wiki", "knowledge graph export", "export to OKF", "OKF bundle", "open knowledge format", "export as markdown bundle", or wants to use their wiki data in another tool. Outputs graph.json, graph.graphml, cypher.txt (Neo4j), postgres.sql (Postgres), and graph.html (interactive browser visualization) into a wiki-export/ directory at the vault root, plus an optional OKF (Open Knowledge Format) markdown bundle under wiki-export/okf/.

clawbio Bundle

Aggregates QC reports from any bioinformatics tool outputs (FastQC, fastp, STAR, Picard, samtools, etc.) into a single MultiQC HTML report plus a ClawBio markdown summary with per-sample QC metrics.

copilotkit Bundle

@copilotkit/react-core — mount the CopilotKit provider (from @copilotkit/react-core/v2) in a Next.js App Router / React Router v7 / TanStack Start / SPA app, drop in CopilotChat/CopilotPopup/CopilotSidebar (v2 chat components ship from react-core/v2 — NOT react-ui, which is CSS-only in v2), access and subscribe to agents with useAgent / useAgentContext / useCapabilities, switch between multiple agents, manage durable Intelligence threads with useThreads, register browser-side tools via useFrontendTool, render tool calls with useRenderTool / useComponent / useDefaultRenderTool, gate execution with useHumanInTheLoop, wire file attachments with useAttachments, configure suggestion pills, and register activity- and custom-message renderers. publicLicenseKey is canonical (publicApiKey is deprecated alias). Load the reference under references/ that matches your task.

credyt Skill

Guide users through defining their pricing strategy for an AI product or SaaS. Covers billing model selection (usage-based, subscription, hybrid), subscription tier pricing, credit/overage costs, real-time vs invoice billing trade-offs, existing PSP integration, custom currency vs fiat, and pricing dimensions. Ends with a personalised pricing strategy summary, MRR projection, visual output (HTML or PDF), and tool recommendations. Use when a user wants to define their pricing, figure out how to charge for their AI product, decide between billing models, understand the real-time vs invoice billing trade-off, or evaluate what tools to use for monetisation.

jimliu Bundle

Create polished design artifacts as self-contained HTML: UI mockups, interactive prototypes, wireframes, landing pages, dashboards, app screens, mobile apps, slide decks (a.k.a. PPT / PowerPoint presentations), documents and résumés, animations, 3D objects, research reports, HTML email, diagrams, fliers, and visual explorations. Use whenever the user asks to design, mock up, prototype, wireframe, visualize, explore, or make a PPT/deck for an interface, product screen, user flow, content layout, visual artifact, or pitch/deck concept, even if they do not say "design". Also use to export a deck built with this skill to PowerPoint (PPT/PPTX) — but only decks authored here (deck-stage / this skill's slide-structured HTML), NOT arbitrary HTML, so confirm the target is such a deck first. Also use for setting up, importing, or authoring reusable design systems, UI kits, brand tokens, or component libraries. Harness-agnostic for Claude Code, Cursor, Codex Agent, and similar file-capable agents.

kayforkind Skill

Orchestrates first-run setup for Vercel-linked repos: vercel link, env pull, AUTH_SECRET, then db:push/seed/dev in that order (next-forge uses pnpm migrate). Use when cloning or repairing a project that depends on Neon, Auth, Blob, or other Vercel integrations. Not for the CSS Bootstrap framework or UI component libraries. Do not use to author CI deploy workflows (deployments-cicd) or to mint throwaway neon.new databases (claimable-postgres).

kayforkind Skill

Builds interactive terminal UIs with React Ink: Box and Text, Yoga flexbox, useInput, useFocus, Static logs, and create-ink-app. Use when the user wants a React CLI, Ink components, or styled stdout UI. Not for React DOM, Next.js, or React Native screens. Do not use for shell scripts that only print text.

kayforkind Skill

Fetches and extracts pages with Scrapling HTTP Fetcher, DynamicFetcher for JS-rendered HTML, and Spider crawling via CLI or Python. Use when static or JS pages must be extracted after a generic web extract fails, or when crawling URLs the user is allowed to collect. Not for CAPTCHA solving, credential stuffing, or ignoring robots and site terms; never treat stealth fetchers as a license for unauthorized access.

kayforkind Skill

Configures Turborepo v2.8 monorepo pipelines including turbo.json tasks, remote cache, filter and affected CI, boundaries, and microfrontend deploys. Use when orchestrating JS/TS workspace builds or optimizing turbo CI. Not for a single Next.js app with no shared packages, Vercel Functions runtimes (vercel-functions), or package-manager workspaces that never invoke turbo.

kid-sid Bundle

Use when building or refactoring Angular applications — choosing between signals, RxJS, and NgRx for state, configuring routing with guards and lazy loading, optimizing change detection, or writing TestBed component tests.

matteocervelli Skill

Query, update, and audit the registry of all Claude Code components (skills, agents, rules, hooks, plugins) with PDCA lifecycle tracking. Use when listing/inspecting components, finding stale ones, or registering new ones. Trigger on "list skills", "component registry", "what skills exist", "stale skills", "/registry".

mblode Bundle

nexu-io Skill

Generate animation-rich HTML presentations with visual style previews. Useful for online keynotes, embedded talks, and interactive briefs.

openakita Bundle

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.

openclaw Skill

Add a capability to the CURRENT Convex app — consults the served Convex capability catalog for always-current procedures (billing, crons, auth, agent, search, …); falls back to built-in hosting or @convex-dev component search. TRIGGER when the user runs /add, or asks to add hosting/publishing or any backend capability to an existing Convex app.

paulrberg Bundle

paulrberg Bundle

Use for Tailwind v4 styling: add/fix classes, configure or migrate Tailwind, use tailwind-variants, or tw-animate-css.

posthog Bundle

Internal PostHog developer frontend/browser QA skill. Use only when a PostHog developer explicitly asks to run frontend QA, browser-test a PR, verify a UI flow against the local PostHog stack, use qa-frontend, or QA current frontend changes with browser/runtime evidence. Do not use for generic code review, PR review, "check my changes", CI debugging, or security audit; use qa-team, debugging-ci-failures, or security-audit instead. Runs in PR mode or local mode, plans adaptive browser and visual checks, drives browser MCP/tooling such as Playwright MCP or Chrome DevTools MCP, captures evidence, and applies only approved/narrow fixes.
