Use when: taking screenshots, generating PDFs from HTML or URLs, web scraping content, crawling websites, browser automation tasks, testing web applications, managing browser sessions, performing batch browser operations, integrating with AI for content extraction, or encountering browser rendering errors, XPath selector errors, browser timeout issues, concurrency limits, memory exceeded errors, or "Cannot read properties of undefined (reading 'fetch')" errors. Keywords: browser rendering cloudflare, @cloudflare/puppeteer, @cloudflare/playwright, puppeteer workers, playwright workers, screenshot cloudflare, pdf generation workers, web scraping cloudflare, headless chrome workers, browser automation, puppeteer.launch, playwright.chromium.launch, browser binding, session management, puppeteer.sessions, puppeteer.connect, browser.close, browser.disconnect, XPath not supported, browser timeout, concurrency limit, keep_alive, page.screenshot, page.pdf, page.goto, page.evaluate, incognito context, session reuse, batch scraping, crawling websites
Choosing the right concurrency abstraction in .NET - from async/await for I/O to Channels for producer/consumer to Akka.NET for stateful entity management. Avoid locks and manual synchronization unless absolutely necessary.
Expert Core Data guidance (iOS/macOS): stack setup, fetch requests & NSFetchedResultsController, saving/merge conflicts, threading & Swift Concurrency, batch operations & persistent history, migrations, performance, and NSPersistentCloudKitContainer/CloudKit sync.
Enforce repository coding standards for Swift 6.2 concurrency, Swift language rules. Use when reviewing or implementing Swift code changes.
Python skill router. Use when planning, implementing, or reviewing Python changes and you need to select focused skills for workflow, design, typing/contracts, reliability, testing, data/state, concurrency, integrations, runtime operations, or notebook async behavior.
Use when ANY question involves Apple framework APIs, Swift compiler errors, or Xcode-bundled documentation. Covers Liquid Glass, Swift 6.2 concurrency, Foundation Models, SwiftData, StoreKit, 32 Swift compiler diagnostics.
iOS crash-hunter skill that finds and fixes gnarly concurrency, memory, and I/O bugs using TDD. Every rule shows dangerous code, a failing test that proves the crash, and the fix that makes it pass. Complements ios-testing, swift-optimise, and other ios-*/swift-* skills. Triggers on tasks involving data races, retain cycles, deadlocks, async/await pitfalls, file corruption, thread safety, or crash debugging in Swift/iOS apps.
This skill should be used when the user asks to review, refactor, debug, or optimize Vue 3 code for performance, correctness, SSR hydration, reactivity stability, request concurrency, TypeScript safety, or bundle size.
Unify EliteForge Java coding specifications, covering code style, comment specifications, POJO/enum/util classes, control statements, logging, concurrency, MyBatis-Plus, transactions, Spring, inter-service calls, Maven, databases, gateways, interface management, project structure, etc. Use this when users mention terms like "Java specification", "coding specification", "code style", "enum writing", "POJO specification", "logging specification", "transaction processing", "inter-service calls", "interface prefix", "domain model", "Maven version", "internationalization".
REST and gRPC API design patterns for Go services. Covers HTTP handlers, middleware, routing, request/response patterns, versioning, pagination, graceful shutdown, and OpenAPI documentation. Use when designing APIs, writing HTTP handlers, implementing middleware, structuring REST endpoints, or setting up gRPC services. Trigger examples: "design API", "REST endpoints", "HTTP handler", "middleware pattern", "graceful shutdown", "gRPC service", "API versioning". Do NOT use for general architecture (use go-architecture-review) or concurrency in handlers (use go-concurrency-review).
Use when profiling async/await performance, diagnosing actor contention, or investigating thread pool exhaustion. Covers Swift Concurrency Instruments template, task visualization, actor contention analysis, thread pool debugging.
Go concurrency patterns including goroutine lifecycle management, channel usage, mutex handling, and sync primitives. Use when writing concurrent Go code, spawning goroutines, working with channels, or documenting thread-safety guarantees. Based on Google and Uber Go Style Guides.
