Hexagonal architecture layering for Java services with strict boundaries. Trigger: When structuring Java apps by Domain/Application/Infrastructure, or refactoring toward clean architecture.
Refactors legacy Java code to modern patterns and best practices. Use when modernizing old Java code, converting to Java 8+ features, refactoring legacy applications, applying design patterns, improving error handling, extracting methods/classes, converting to streams/Optional/records, or migrating from old Java versions. Works with pre-Java 8 code, procedural Java, legacy frameworks, and outdated patterns.
Spring Boot 3 patterns for configuration, DI, and web services. Trigger: When building or refactoring Spring Boot 3 applications.
Use when users say "create a skill", "make a new skill", "build a skill", "skill for X", "package this as a skill", or when refactoring/updating/auditing existing skills that extend agent capabilities with specialized knowledge, workflows, or tool integrations.
Systematic code refactoring following Martin Fowler's catalog. Methodologies: characterization tests, Red-Green-Refactor, incremental transformation. Capabilities: SOLID compliance, DRY cleanup, code smell detection, complexity reduction, legacy modernization, design patterns, functional programming patterns. Actions: refactor, extract, inline, rename, move, simplify code. Keywords: refactor, SOLID, DRY, code smell, complexity, extract method, inline, rename, move, clean code, technical debt, legacy code, design pattern, characterization test, Red-Green-Refactor, functional programming, higher-order function, immutability, pure function, composition, currying, side effects. Use when: improving code quality, reducing technical debt, applying SOLID principles, fixing DRY violations, removing code smells, modernizing legacy code, applying design patterns.
Design System Governance Workflow for auditing, refactoring, and syncing enterprise design systems, design tokens, Figma variables, and developer handoff outputs.
CMake build system skill for C/C++ projects. Use when writing or refactoring CMakeLists.txt, configuring out-of-source builds, selecting generators (Ninja, Make, VS), managing targets and dependencies with target_link_libraries, integrating external packages via find_package or FetchContent, enabling sanitizers, setting up toolchain files for cross-compilation, or exporting CMake packages. Activates on queries about CMakeLists.txt, cmake configure errors, target properties, install rules, CPack, or CMake presets.
Architecture optimization team skill. Analyzes codebase architecture, designs refactoring plans, implements changes, validates improvements, and reviews code quality via CSV wave pipeline with interactive review-fix cycles.
Python coding standards and best practices. Applicable to code generation, code review, and code refactoring scenarios.
Go interface design patterns: implicit interfaces, consumer-side definition, interface compliance verification, composition, the accept-interfaces-return-structs principle, and common pitfalls. Use when designing interfaces, decoupling packages, defining contracts, reviewing interface usage, or refactoring for testability. Trigger examples: "design interface", "accept interfaces return structs", "interface compliance", "consumer-side interface", "interface composition". Do NOT use for HTTP handler patterns (use go-api-design) or general code review (use go-code-review).
Use when onboarding to an existing codebase that lacks specifications — exhaustively traces code paths and produces implementation-free behavioral specifications for safe refactoring, feature addition, or legacy modernization
Clinic-architecture-aligned iOS animation craft guidelines for SwiftUI (iOS 26 / Swift 6.2) covering motion tokens, spring physics, gesture continuity, spatial transitions, micro-interactions, and accessibility. Enforces @Equatable on animated views and keeps animation state aligned with Domain/Data feature boundaries. Use when writing, reviewing, or refactoring SwiftUI animation code under the clinic modular MVVM-C architecture.
