Scaffold a unified, cross-platform color theme system into an Expo Router app. Sets up semantic system colors (resolved from native iOS labels and Android Material You dynamic colors), brand colors, automatic dark/light re-rendering, the React Navigation ThemeProvider, and a useColors() / useTheme() context hook. Use whenever a user wants to set up theming, dark mode, dynamic or Material You colors, a unified color system, or a useColors/useTheme hook in an Expo / React Native app, even if they do not name a specific approach.
Create Tufte-inspired data reports and infographic dashboards as standalone HTML files. Uses EB Garamond for text, Monaspace Argon for numbers, Chart.js for interactive charts, and inline SVG sparklines. Produces publication-quality reports with 2-column narrative+data layouts, status dashboards, scroll animations, and responsive mobile support. Use this skill whenever the user wants to create a data report, activity dashboard, infographic, personal analytics page, health tracker visualization, or any document that combines narrative text with interactive charts and tables. Also triggers for "make a report like Tufte", "create an infographic", "build a dashboard", "visualize my data", or requests for beautiful data-driven documents.
Fetch recent posts from one or more X/Twitter accounts through twitterapi.io, output structured JSON/CSV records, optionally sync records to Feishu/Lark Bitable through feishu-cli, and optionally guide recurring execution through OpenClaw, Codex automations, cron, or launchd. Use when the user wants to monitor X bloggers, collect recent tweets, export tweet metrics, append tweets to Feishu Bitable, or set up a scheduled Twitter/X account tracking workflow.
Use Univer (spreadsheet engine) in Node.js backend environments for headless data processing, batch report generation, server-side formula calculation, and automated workbook manipulation. Use when the user needs to create, read, or modify spreadsheets on the server without a browser, run Univer in Node.js, use createUniverOnNode, UniverRPCNodeMainPlugin, child_process fork for formula workers, server-side XLSX/JSON processing, or batch cell operations via Facade API in a backend context. Triggers include “Node.js,” “server side,” “backend,” “headless,” “batch generate,” “automated report,” “createUniverOnNode,” “rpc-node,” “formula worker,” or “Univer in Node”
Workflow required before any Mule application upgrade work. Call use_skill as your FIRST action — before reading project files (pom.xml, mule-artifact.json) or editing versions yourself — whenever the user asks to upgrade, migrate, bump, modernize, or move a Mule app to a newer Java version, a newer Mule Runtime version, or both. Covers upgrading Java and/or Mule Runtime, getting latest compatible connector versions, updating connector and plugin versions, and fixing impacts from operation changes in flows, DataWeave scripts, and MUnit tests. Even a targeted single-version bump like 'move this app to Java 17' or 'upgrade the runtime to 4.6' requires this workflow — do not hand-edit pom.xml versions and attempt the change yourself. When you call this skill, it must be the only tool call in that response.
UX/UI design guidance for building, reviewing and critiquing interfaces, grounded in Nielsen heuristics, the Laws of UX and WCAG 2.2, with modern 2026 best practices. Covers interaction patterns, forms, navigation, accessibility, UX writing, onboarding, AI and chat interfaces, i18n/RTL, and more, with reference files loaded on demand.

Provides: Hook formulas, psychological trigger frameworks, retention benchmarks, pattern interrupt techniques, and actionable retention improvement strategies.
Generate clickable low-fidelity, hand-drawn wireframes (Balsamiq style) for web UI from a text description: a self-contained single-page prototype with sketchy wired-elements components, doodle icons and a graph-paper background. Focuses on layout, content and flow before visual design.
Use this skill when the user asks to “create an agent,” “add an agent,” “write a subagent,” “agent frontmatter,” “when to use description,” “agent examples,” “agent tools,” “agent colors,” or “autonomous agent,” or needs guidance on agent structure, system prompts, triggering conditions, or agent development best practices for Claude Code plugins.
Apply Andrej Karpathy-inspired coding-agent guidelines in Codex. Use when writing, reviewing, debugging, or refactoring code to surface assumptions, avoid overengineering, keep edits surgical, and define verifiable success criteria.
Enforces a fixed main() cold-launch order — crash-log sink + FlutterError.onError + PlatformDispatcher.onError installed BEFORE any code that can throw, settings/theme read before runApp so the first frame paints correct, real infra constructed in a composition-root bootstrap() and injected via ProviderScope overrideWithValue over throwing placeholder providers, non-blocking warm-up deferred to addPostFrameCallback, exactly two error handlers with NO runZonedGuarded, ProviderException unwrapped before logging, and a WidgetsBindingObserver that flushes durable state on background/resume. Use when editing lib/main.dart, main_<flavor>.dart, bootstrap.dart or app.dart, reordering anything in main(), adding a splash/onboarding/permission gate, restoring theme before first paint, wiring a DB or service into ProviderScope, handling app-lifecycle background/resume flushes, or chasing cold-start latency, ANRs, or first-frame jank.

Create dark-themed, animated technical diagrams as self-contained HTML+SVG files—flowcharts with visibly flowing connectors and architecture diagrams where requests travel through the system as light dots (Diagrid/Temporal landing-page style). Use whenever the user asks for a flowchart, workflow, pipeline, process diagram, state machine, system architecture, infrastructure, cloud, microservices, or network topology diagram—especially when they mention “animated,” “flowing,” “dynamic,” “alive,” “GIF-like,” or want a diagram for a landing page, README, docs, or product demo. Also use it to convert Mermaid source (a mermaid code block or .mmd file) into an animated diagram: “animate this mermaid,” “make this flowchart move.” Prefer this over static diagrams whenever the diagram represents anything that moves: requests, events, data, jobs, messages, or control flow.
Test big ideas in just 5 days. Apply Google Ventures' proven methodology to go from problem to validated prototype without months of development. Use for new product concepts that need validation before building; big feature decisions requiring significant investment; teams stuck in analysis paralysis; startup pivots when direction is uncertain; and high-risk bets where failure is expensive

Use this skill whenever the user wants to extract data from an Axure prototype, reconstruct or clone an Axure page, analyze Axure design tokens, export Axure content, or work with Axure prototype URLs (even if they don't say "Axure" explicitly — look for AxShare links, /start.html#p= URLs, /start.html?id=...&p= URLs, or mentions of wireframes/prototypes hosted online).
Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.
Use this skill to search live software / tech / data / engineering job listings across many countries and markets (and remote) via the freehire.me aggregator's public API, or to look up a specific posting. It aggregates roles from ~50 ATS platforms into one schema, so a single skill covers many markets — but its faceted filtering (skills, category, seniority) is tuned tech-first, so scope triggers to technical roles. Trigger phrases: find a tech job, software job search, developer jobs, engineering vacancies, data/ML jobs, DevOps roles, remote developer jobs, "are there any <tech role> jobs in <place>", look up this freehire job posting

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
