Delay loading JavaScript for less important parts of the page to improve Time to Interactive.
Fetch real-time web data via the hasdata CLI. Use when the user wants search results, news, fact-checks, product or seller info, current prices, reviews, real-estate listings or sold comps, vacation rentals, local-business contact details, job postings, salary research, search trends, images, flights, social profiles, or to scrape any URL (HTML / markdown / AI-extracted JSON). Also use when the user asks to summarize a web page, ground a prompt with current information, verify a URL is live or render a JavaScript-heavy page, monitor a price over time, find a phone number or address for a business, build a competitor map, identify recent sold comparables, gather employer reviews, fan out a list of items to per-item details, or check what's being said online about a topic right now. Backed by Google, Bing, Amazon, Shopify, Zillow, Redfin, Airbnb, Yelp, YellowPages, Indeed, Glassdoor, Instagram, Google Maps / Trends / News / Images / Flights / Events APIs.
Run a comprehensive technical SEO audit covering crawlability, indexability, rendering, site architecture, structured data, page experience, security, and internationalization. Use this skill whenever the user asks about technical SEO, crawl issues, indexing problems, sitemaps, robots.txt, canonical tags, schema markup, page speed, Core Web Vitals, hreflang, redirects, or site-wide search performance. Triggers on technical SEO, site audit, crawlability, indexability, sitemap, robots.txt, canonical, redirect chain, schema, JSON-LD, Core Web Vitals, page speed, hreflang, mobile usability, HTTPS, security headers, render-blocking, JavaScript SEO. Also triggers when a site has indexing problems, traffic drops, or migration concerns, even if 'technical SEO' is not said explicitly.
Bridge AI assistants to Figma Desktop via MCP — draw UI with JavaScript, read designs as structured data, extract screenshots and tokens
AlpineJS best practices and patterns. Use when writing HTML with Alpine.js directives to avoid common mistakes like long inline JavaScript strings.
Render an ad-hoc interactive map inline in the chat from a deck.gl declarative spec via the CARTO MCP server's view_map tool. Use whenever the user asks to map, visualize, or show the geographic distribution of points, polygons, hexagons, quadbins, clusters, density (heatmaps), or raster — and the map is exploratory or throwaway, not meant to be saved as a permanent CARTO Builder map. Triggers on "show me X on a map", "visualize Y", "make a heatmap of Z", "render the points/clusters/raster of W". Distinct from carto-create-builder-maps (CLI authoring of permanent maps), carto-preview-builder-map (loading an existing saved Builder map), and carto-develop-app (writing a from-scratch deck.gl app in TypeScript / JavaScript).
Use whenever you need an email address to receive something and then read or wait for it, especially during a signup or login flow. PROACTIVELY, and you can usually do this without asking the user first: a service is about to send a verification code, OTP, one-time code, 2FA or two-factor code, confirmation link, magic link, or password reset and you need to wait for it and read the value out; you are signing up for or registering with a service and must confirm an email address to continue; you need a fresh, managed, throwaway, or burner address instead of using a real one; you sent something and need to watch for what lands. REACTIVELY: the user asks "did it arrive?", "check the inbox", "what came in?", "wait for the email", or wants an address to catch replies, codes, receipts, or alerts. Provides a managed `*.primitive.email` address plus `primitive emails latest` and `primitive emails wait` to read and block for mail, and hosted Functions to run JavaScript on every inbound message. No SMTP, no DNS, no mail server. Use this when a third party sends mail TO you; to send your own message and wait for its reply, use the primitive-chat skill. Gets a free `*.primitive.email` address via `primitive agent start-agent-signup` if you do not already have one. Part of the Primitive CLI (Primitive, primitivedotdev, primitive.dev; the `primitive` or `prim` command).
Reduce JavaScript and CSS bundle sizes through code splitting, tree shaking, and optimization techniques. Improve load times and overall application performance.
Expert TypeScript developer specializing in type-safe application development, advanced type systems, strict mode configuration, and modern TypeScript patterns. Use when building type-safe applications, refactoring JavaScript to TypeScript, or implementing complex type definitions.
Electron development guidelines for building cross-platform desktop applications with JavaScript/TypeScript
Complete guide for @solana/kit - the modern, tree-shakeable, zero-dependency JavaScript SDK from Anza. Covers RPC connections, signers, transaction building with pipe, signing, sending, and account fetching with full TypeScript support.
Write Tampermonkey userscripts for browser automation, page modification, and web enhancement. Use when: creating browser scripts, writing greasemonkey scripts, automating user interactions, injecting CSS or JavaScript into web pages, modifying website behaviour, building browser extensions, hiding unwanted page elements, adding form auto-fill, scraping website data, intercepting requests, detecting URL changes in SPAs, or storing persistent user preferences. Covers userscript headers (@match, @grant, @require), synchronous and async GM_* API functions, common patterns (DOM mutation, URL change detection, element waiting), security sandboxing, and cross-browser compatibility (Chrome, Firefox, Edge).
