simon-he95 Bundle

Integrate markstream-vue into a Vue 3 app. Use when Codex needs to add the Vue 3 renderer, import CSS in the right order, choose renderer and DOM modes, choose built-in, plain, or custom code-block paths, choose between `content` and `nodes`, coordinate long AI timelines with `MarkstreamVirtualTimeline`, `useMarkstreamVirtualAdapter`, or `vue-virtual-scroller`, enable optional peers such as stream-diffs, Mermaid, KaTeX, D2, or Infographic, or wire scoped custom components in a non-Nuxt Vue repository.

simon-he95 Bundle

Integrate markstream-vue into a Nuxt 3 or Nuxt 4 app. Use when Codex needs client-only boundaries, SSR-safe setup, browser-only peer gating, worker-aware initialization, renderer `mode` selection, or a safe `MarkdownRender` integration inside pages, components, or Nuxt plugins.

simon-he95 Bundle

Integrate markstream-vue2 into a Vue 2.6 or 2.7 app. Use when Codex needs Vue 2-compatible setup, `@vue/composition-api` decisions, CSS wiring, optional peer setup, or scoped Markstream overrides in a Vue 2 repository that is not specifically Vue CLI / Webpack 4 constrained.

simon-he95 Bundle

Integrate the beta markstream-react package into a React 18+ or Next app. Use when Codex needs to add the React renderer, choose the root, `next`, or `server` entrypoint, import CSS correctly, choose between `content` and `nodes`, keep client boundaries safe, add renderer-local `streamingComponents` or `htmlComponents`, use parser transforms, or prepare a repo for `react-markdown` migration.

simon-he95 Bundle

Integrate the beta markstream-svelte package in Svelte 5 or SvelteKit apps. Use when Codex needs Svelte 5 runes, CSS and optional peers, smooth streaming, worker setup, renderer-local or scoped custom components, or SSR-safe boundaries. Svelte 4 is unsupported.

simon-he95 Bundle

Integrate the alpha markstream-angular package into an Angular 20+ app. Use when Codex needs standalone component imports, signal-based examples, CSS wiring, custom HTML tags or customComponents setup, or optional peer integration in an Angular repository.

simon-he95 Bundle

Install and wire markstream-vue, markstream-react, markstream-vue2, markstream-angular, or markstream-svelte into an existing repository. Use when Codex needs to choose the right package, install the smallest framework-specific peer-dependency set, fix CSS/reset order, choose Vue 3 renderer mode and built-in, plain, or custom code-block paths, decide between `content`, `nodes`, and Vue 3 virtual-scroll coordination, or add a minimal working renderer example.

simon-he95 Bundle

Integrate markstream-vue2 into a Vue 2 Vue CLI or Webpack 4 app. Use when Codex needs Webpack 4-friendly setup, CDN worker fallbacks for Mermaid or KaTeX, `dist/index.css` imports, Vue 2 composition-api shims, or code block choices limited to `stream-diffs` or plain `<pre>`.

simon-he95 Bundle

Audit and migrate existing Markdown rendering to Markstream, or upgrade a markstream-vue 1.x integration to 2.x. Use when Codex needs to replace another renderer, classify direct vs custom vs plugin-heavy adoption, preserve behavior during adoption, migrate custom renderers into scoped Markstream overrides, decide when `nodes` streaming is worth adopting, or replace removed 1.x code-block dependencies, APIs, preview payloads, and parser types.

simon-he95 Bundle

Integrate markstream-vue2 into a Vue 2 plus Vite app. Use when Codex needs Vite-friendly worker imports, `?worker` or `?worker&inline` setup for Mermaid or KaTeX, modern CSS ordering, or Vue 2 compatibility in a Vite-based repository.

buzzdan Bundle

Linter-driven refactoring patterns to reduce complexity and improve code quality in React/TypeScript. Use when ESLint fails with SonarJS complexity issues (cognitive, cyclomatic, expression) or when code feels hard to read/maintain. Applies component extraction, hook extraction, and simplification patterns.

buzzdan Bundle

ADVISORY validation of code against design principles, accessibility, and best practices that linters cannot fully enforce. Use after linter passes and tests pass to validate design quality. Categorizes findings as Design Debt, Readability Debt, or Polish Opportunities. Does NOT block commits.

tractorjuice Bundle

PlantUML syntax reference, C4-PlantUML first, for writing or fixing a diagram in an artefact: sequence, class, activity, state, ER, component, deployment and use-case diagrams, skinparams and themes, C4 layout conflicts and rendering errors. Not needed for Mermaid (mermaid-syntax), or when the request is for a governed diagram artefact with document control, which /arckit:diagram produces.

get-convex Skill

Convex backend rules — consult this whenever writing or editing any code inside a convex/ directory (schemas, queries, mutations, actions, HTTP endpoints, crons, file storage, auth, component installation). TRIGGER before touching convex/ functions, so the code uses the object-form syntax, validators, indexes, and component patterns that generic models get wrong.

rainmanjam Skill

Forms, flows and screens. Structure, naming and clarity of user-facing interaction code: component boundaries, state ownership, and keeping presentation separable from the rules behind it.

triggerdotdev Skill

Author and run a durable AI chat agent with chat.agent from @trigger.dev/sdk/ai: the per-turn run loop, why you MUST take streamText from the run argument rather than importing it from ai, returning a StreamTextResult vs calling chat.pipe(), the two server actions (chat.createStartSessionAction + auth.createPublicToken), and wiring useChat to useTriggerChatTransport. Load this when building, modifying, or debugging a chat backend (the agent task or its lifecycle hooks) or its React transport, when declaring typed tools or custom data parts, or when migrating a plain AI SDK streamText route to chat.agent.

get-convex Bundle

Initializes a new Convex project from scratch or adds Convex to an existing app. Use this skill when starting a new project with Convex, scaffolding with npm create convex@latest, adding Convex to an existing React, Next.js, Vue, Svelte, or other frontend, wiring up ConvexProvider, configuring environment variables for the deployment URL, or running npx convex dev for the first time, even if the user just says "set up Convex" or "add a backend."

zaaakher Skill

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.

contentstack Skill

Use for AGP, Gradle plugins, JaCoCo, signing, and native Android build concerns in contentstack-android.

nikiforovall Skill

Run code quality checks on the claude-code-kanban project. Use this skill whenever the user wants to check code formatting, linting, or overall code quality for the public/app.js and public/style.css files. Trigger on phrases like "check quality", "lint", "format check", "style check", "quality gates", or any mention of code quality/standards.

kensaurus Skill

Pass/fail health check across every Mushi Mushi pipeline component — CLI credentials, API reachability, edge functions, BYOK key pool, QA cron. Use when "is mushi working", "mushi health check", "check mushi pipeline", "mushi deploy check", "pipeline not responding", or right after setup.

irahardianto Skill

Generates distinctive, production-grade mobile interfaces for Flutter and React Native. Prioritizes platform-native patterns, adaptive layouts, and fluid motion. Use when building mobile apps, screens, widgets, or when the user requests to style or create visually striking mobile UI.

rerun-io Skill

How raw multimodal robot data maps onto the Rerun data model. Read FIRST, before modeling or converting a dataset — and whenever you are about to convert/ingest/preprocess robot data into an .rrd or build a Rerun recording, even if not asked for the data model. Resolves the entity-vs-component, property-vs-component-vs-layer, and static-vs-temporal decisions and routes to the mechanism (do it with readers and lenses, not hand-built chunks or per-message rr.log): rerun-chunk-processing and the importer skills rerun-mcap, rerun-urdf, rerun-parquet, rerun-lerobot.

aws-samples Bundle

Conduct comprehensive AWS system architecture resilience analysis and risk identification. Use when the user wants to perform architecture analysis, identify failure modes, map system components and dependencies, assess risk priorities, or create disaster recovery plans. Also use for failure mode analysis, component dependency mapping, risk scoring, and mitigation strategy design — even if they don't explicitly say "resilience". Automatically invoked for AWS韧性分析, 架构分析, 系统风险评估, AWS韧性评估, 可靠性评估, 灾难恢复规划, 故障模式分析, 组件依赖分析, 风险识别.

pramoddutta Skill

Scans a Playwright spec or Page Object for brittle locators and rewrites them to resilient ones. Use when an SDET says "fix these locators", "my selectors are flaky", "replace XPath with getByRole", "make these locators resilient", or pastes code full of nth-child/CSS-class/text selectors. Produces a before/ after rewrite map plus patched code - the engineer verifies each swap.
