Skill UI

This comprehensive guide details the idiomatic and efficient way to write Scala code. It covers crucial modern practices, such as utilizing functional transforms over traditional loops, embracing pattern matching, using Option/Either for robust error handling instead of null checks or exceptions, and managing concurrency safely. Essential reading for any Scala developer aiming for high-quality, maintainable, and performant codebases.

The Application Insights JavaScript SDK is designed to instrument client-side web applications for Real User Monitoring (RUM). It automatically collects crucial telemetry, including page views, user clicks, AJAX dependencies, unhandled exceptions, and custom events. This SDK supports correlating browser-side activity with backend services and includes specialized support for GenAI agent traces following OpenTelemetry standards.

Diagnose runtime and application failures efficiently. This skill provides structured guidance for debugging crashes, exceptions, and unexpected behavior in deployed applications. Ideal for developers and DevOps engineers troubleshooting production issues.

This skill enables Real User Monitoring (RUM) for browser and web applications using the Application Insights JavaScript SDK. It tracks page views, clicks, AJAX dependencies, exceptions, and custom events. Supports React, Angular, and React Native instrumentation. Includes GenAI agent traces with backend correlation. Ideal for frontend performance and error tracking in TypeScript projects.

This skill enables interactive debugging of source code by setting breakpoints, stepping through execution, and inspecting live variable states. It allows evaluating expressions against running programs and navigating call stacks to trace root causes without restarting. Supports multiple languages including Python, Go, and Rust via the DAP protocol. Ideal for diagnosing crashes, unexpected exceptions, and understanding execution flow.

This skill enables scanning third-party package dependencies for known security vulnerabilities using tools like Snyk, Dependabot, and OWASP Dependency-Check. It covers managing software composition analysis, securing the software supply chain, and meeting compliance requirements. Users learn to configure scanners, interpret results, handle exceptions, and integrate security checks into CI/CD pipelines to automate vulnerability detection and remediation.

This skill teaches you how to handle errors in TypeScript without relying on try/catch blocks. It focuses on using fp-ts Either and TaskEither types to make error handling more predictable and type-safe. Ideal for building APIs, services, and accumulating validation errors. It promotes treating errors as data values rather than exceptions, ensuring cleaner and more maintainable code.

Technique for authorized bug-bounty and penetration-testing engagements that hunts mishandled exceptional conditions in web apps, inducing unhandled exceptions with wrong-type, malformed, or boundary inputs to detect verbose stack traces, ORM internals, server paths, and framework version leaks.
