Pre-submission validation for Google Play releases covering metadata, screenshots, bundle integrity, data safety, and policy compliance. Use when preparing a release to avoid rejections and catch issues before submitting.
Core Web Vitals and performance optimization for Astro sites. LCP, CLS, INP optimization, bundle size, fonts, third-party scripts. Use for performance tuning.
This skill should be used when the user wants to optimize Next.js frontend performance using Lighthouse, bundle analysis, and animation best practices. Use when diagnosing slow pages, optimizing bundle size, or improving Core Web Vitals (LCP, TBT, CLS).
Tests Blazor components. bUnit rendering, events, cascading params, JS interop mocking.
Builds elaborate multi-component claude.ai HTML artifacts using React 18, TypeScript, Vite, Tailwind CSS, and shadcn/ui bundled into single-file deliverables. Use when asked to "create complex artifact", "build React artifact with routing", "use shadcn/ui components", "create stateful web app artifact", or "build multi-component frontend". Provides initialization scripts, development workflow, and Parcel bundling to create sophisticated single-HTML artifacts with state management and modern components. Works with React/TypeScript stack for claude.ai artifacts requiring complexity beyond simple HTML/JSX.
ConvexFS (convex-fs) — path-based file storage and serving component for Convex powered by bunny.net CDN. Covers installation, setup, file upload/download flows, path management, blob lifecycle, atomic transactions (move/copy/delete), compare-and-swap, signed URLs, file expiration, garbage collection, auth for uploads/downloads, multiple filesystems, React integration, and production best practices. Use when working with ConvexFS, uploading files in Convex, serving files via CDN, managing file paths, building file storage features, or configuring bunny.net with Convex. Triggers on: convex-fs, ConvexFS, bunny.net, file upload, file storage convex, blob, commitFiles, registerRoutes, buildDownloadUrl, fs.stat, fs.list, fs.transact, fs.move, fs.copy, fs.delete, fs.writeFile, fs.getDownloadUrl, "how do I upload files in Convex", "serve files from Convex", "ConvexFS setup".
Check and validate MTHDS bundles for issues. Use when user says "validate this", "check my workflow", "check my method", "does this .mthds make sense?", "review this pipeline", "any issues?", "is this correct?". Reports problems without modifying files. Read-only analysis.
Fix issues in MTHDS bundles. Use when user says "fix this workflow", "fix this method", "repair validation errors", "the pipeline is broken", "fix the .mthds file", after /check found issues, or when validation reports errors. Automatically applies fixes and re-validates in a loop.
Localize templates, forms, and content in B2C Commerce. Use when adding translations, working with resource bundles (*.properties files), using Resource.msg, or implementing multi-locale support. Covers locale folders, string externalization, and date/currency formatting.
Use this skill when profiling application performance, debugging memory leaks, optimizing latency, benchmarking code, or reducing resource consumption. Triggers on CPU profiling, memory profiling, flame graphs, garbage collection tuning, load testing, P99 latency, throughput optimization, bundle size reduction, and any task requiring performance analysis or optimization.
TanStack Router bundler plugin for route generation and automatic code splitting. Supports Vite, Webpack, Rspack, and esbuild. Configures autoCodeSplitting, routesDirectory, target framework, and code split groupings.
Use when optimizing application performance, reducing load times, improving database queries, meeting performance budgets, or diagnosing bottlenecks in web applications or APIs. Triggers: slow page loads, poor Web Vitals, database timeouts, large bundle size, user-reported sluggishness, scaling preparation.
