Performance optimization expert covering profiling, benchmarking, memory allocation, SIMD, cache optimization, false sharing, lock contention, and NUMA-aware programming.
Run targeted linting, formatting, and code quality checks on modified files. Use this to validate code style, type safety, security, and other quality metrics before committing. Supports running all checks or targeting specific checks on specific files for efficient validation.
Guides the agent through implementing authentication and authorization in FastAPI applications. Triggered when users ask to "add authentication", "implement login", "add JWT tokens", "create OAuth2 flow", "hash passwords", "protect endpoints", "add role-based access", "implement RBAC", "add API key auth", "secure the API", or mention authentication, authorization, JWT, OAuth2, password hashing, bcrypt, access tokens, refresh tokens, security dependencies, or API security.
Review reusable project knowledge and decide what belongs in project memory, notepad, or durable docs
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.
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
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.
Analyze complex systems through stocks, flows, and feedback loops to find high-leverage interventions. For organizational, environmental, social, and technical systems exhibiting circular causality. NOT for linear problems or simple cause-effect chains.
Master core refactoring operations: Extract Method, Extract Class, Replace Conditional with Polymorphism, Introduce Variable, Simplify Conditionals, Move Method, and Rename. Organized by operation type with before/after examples. Use when refactoring code structure, improving clarity, reducing duplication, or dealing with complex conditionals.
Dynamic path segments ($paramName), splat routes ($ / _splat), optional params ({-$paramName}), prefix/suffix patterns ({$param}.ext), useParams, params.parse/stringify, pathParamsAllowedCharacters, i18n locale patterns.
Scaffold production-ready React Native apps using the @codewithbeto/ship CLI. Use when the user wants to create a new app from a Code with Beto template, scaffold a project with Platano, or run `bunx @codewithbeto/ship`. Always use flag-based (non-interactive) mode — the interactive TUI requires a terminal.
