Code review and quality analysis skill. Used to review code, identify potential issues, and provide improvement suggestions. Activated when users request code review, code quality analysis, or best practice recommendations.
Enforce Test-Driven Development (TDD) workflow for all code changes. Apply PROACTIVELY by default using Red-Green-Refactor cycles for features, bug fixes, and refactoring.
Use when encountering bugs, unexpected behavior, test failures, or errors during development. Enforces a rigorous 4-phase investigation process that prevents shotgun debugging. Triggers: test failure, runtime error, unexpected behavior, production incident, performance regression.
Use before claiming any task is complete, any feature works, or any bug is fixed - enforces fresh verification evidence through a 5-step HARD-GATE protocol that prevents false completion claims
Generates comprehensive, workable unit tests for any programming language using a multi-agent pipeline. Use when asked to generate tests, write unit tests, improve test coverage, add test coverage, create test files, or test a codebase. Supports C#, TypeScript, JavaScript, Python, Go, Rust, Java, and more. Orchestrates research, planning, and implementation phases to produce tests that compile, pass, and follow project conventions.
Review reusable project knowledge and decide what belongs in project memory, notepad, or durable docs
Real User Monitoring (RUM), Web Vitals, user sessions, mobile crashes, page performance, user interactions, and frontend errors. Query web and mobile frontend telemetry.
Log queries, filtering, pattern analysis, and log correlation. Search and analyze application and infrastructure logs.
Use when starting any implementation task, feature request, bug fix, or refactoring work. Triggers on /plan command, before any code is written, when requirements need structured analysis, or when transitioning from brainstorming to implementation. Forces question-asking, approach comparison, and explicit approval before any code.
Guide Claude on creating visually distinctive, polished Vaadin 25 interfaces that go beyond default theme styling. This skill should be used when the user asks to "make it look good", "improve the design", "style the view", "make it visually appealing", "add polish", "design a UI", "create a beautiful interface", or when building a new view where visual quality matters. Also trigger when the user wants to add animations, visual effects, or build polished component compositions in a Vaadin application.
Provides reverse engineering techniques for CTF challenges. Use when analyzing binaries, game clients, obfuscated code, esoteric languages, custom VMs, anti-debugging, anti-analysis bypass, WASM, .NET, APK (including Flutter/Dart AOT with Blutter), HarmonyOS HAP/ABC, Python bytecode, Go/Rust/Swift/Kotlin binaries, VMProtect/Themida, Ghidra, GDB, radare2, Frida, angr, Qiling, Triton, binary diffing, macOS/iOS Mach-O, embedded firmware, kernel modules, game engines, or extracting flags from compiled executables.
Used when accessibility audits are required or when implementing WCAG 2.2 (including ARIA, keyboard accessibility, and screen reader support).
