Review and refactor React and Next.js code to address slow loading and interactions. Prioritized guidance covers sequential data requests, downloaded JavaScript size, server processing, repeated rendering, and browser work, with examples for choosing relevant improvements.
Build or review Java services with Quarkus 3.x using patterns for REST APIs, database access with Panache, and messaging with Apache Camel. Examples cover layered code structure, validation, transactions, and asynchronous processing, where work completes separately from the main flow.
Explore a web app in the browser to find functional, visual, and usability issues. The skill organizes screenshots, console errors, and reproduction steps into a Markdown bug report, with findings grouped by severity and category.
Inspect compressed JavaScript bundles, the files that package application code, to find excessive size and loading costs. Recommend splitting code, removing unused portions, and reviewing dependencies based on measured effects on page responsiveness.
Audit JavaScript delivered to modern browsers for unnecessary older code and compatibility patches. Confirm performance costs with measurements, then review build targets and browser-specific delivery to reduce avoidable download size and processing work.
Review JavaScript that changes a parent element’s appearance based on its children. Find opportunities to replace class toggling with CSS :has() rules, and explain how those rules express conditions involving child elements.
Set up ESLint, a tool that checks JavaScript for errors and coding rule violations. Configure shared rules, connect checks to editors and automated workflows, and review flagged code alongside its behavior in the browser.
Review the loading order of CSS and JavaScript to address rendering delays and flashes of unstyled content. Suggest changes to the document head, script loading, and critical styles, while checking layouts across screen sizes and interaction states.
Implement large parallel workloads in Java with Azure Batch. Manage groups of computing machines, organize jobs and tasks, inspect progress and output, adjust computing capacity, and schedule recurring jobs using SDK examples.
Build Java applications that extract text, tables, and fields from documents using Azure AI Document Intelligence. Covers ready-made models for invoices and receipts, custom model creation, document classification, authentication, and error handling.
Build server-side calling workflows in Java with Azure Communication Services. Implement automated phone menus, incoming and outgoing calls, transfers, recording, spoken prompts, and recognition of speech or keypad input, with examples for handling call events.
Helps implement centralized settings management in Java with Azure App Configuration. Covers environment-specific settings, feature flags that control feature availability, and snapshots that preserve settings at a particular point in time.
Maintain legacy Java code that uses the deprecated Azure Communication CallingServer SDK. Compare old and replacement dependencies, client classes, and recording examples to plan a migration to Call Automation and identify APIs needing verification.
Build content moderation features in Java with Azure AI Content Safety. Analyze text and images for harmful content, retrieve severity scores by category, and manage custom blocklists, which are lists of terms to flag.
Implement Java workflows for Azure AI Foundry projects using SDK examples for authentication, connected resources, datasets, search indexes, and model evaluations. The skill also covers client setup, paginated resource lists, and error handling.
Analyze custom virtual machines written in JavaScript by extracting instruction tables, examining constants, and capturing runtime state. Use the findings to reconstruct how obfuscated code executes, including custom runtimes used in risk-control engines.
Build Helidon 4 applications on Java 21 or later with guidance for SE and MP. Apply practical patterns for HTTP endpoints, database access, configuration, testing, and security while accounting for API changes from Helidon 3.
Inspect suspicious PDFs without opening them in a document viewer. Use peepdf, pdfid, and pdf-parser to examine internal objects, extract embedded code and files, and report threat indicators such as URLs and hashes.
Choose WxJava Maven modules for WeChat services such as official accounts, mini programs, and payments. The skill identifies suitable dependencies, version management, integration options, and examples, including choices for single or multiple accounts.
Diagnoses and fixes Java style violations in the FE module using Checkstyle, a tool that checks coding rules. It interprets errors, applies the project's formatting and import restrictions, and reruns checks to verify fixes.

Use when you need to set up, review, or improve Java integration tests — including generating a BaseIntegrationTest.java with WireMock for HTTP stubs, detecting HTTP client infrastructure from import signals, injecting service coordinates dynamically via System.setProperty(), creating WireMock JSON mapping files with bodyFileName, isolating stubs per test method, verifying HTTP interactions, or eliminating anti-patterns such as Mockito-mocked HTTP clients or globally registered WireMock stubs. This should trigger for requests such as Review Java code for integration tests; Apply best practices for integration tests in Java code; Write Java integration tests with real infrastructure boundaries; Improve Testcontainers integration tests for Java code; Review integration test setup and teardown in Java projects.
