Design, refactor, analyze, and review code by applying the principles and patterns of tactical domain-driven design. Triggers on: domain modeling, aggregate design, 'entity', 'value object', 'repository', 'bounded context', 'domain event', 'domain service', code touching domain/ directories, rich domain model discussions.
Follow the principles of Robert C. Martin's *Clean Code* for code review, refactoring, and writing. Covers best practices for naming, functions, comments, and error handling.
Use when you need to review, improve, or refactor Java code for generics quality — including avoiding raw types, applying the PECS (Producer Extends Consumer Super) principle for wildcards, using bounded type parameters, designing effective generic methods, leveraging the diamond operator, understanding type erasure implications, handling generic inheritance correctly, preventing heap pollution with @SafeVarargs, and integrating generics with modern Java features like Records, sealed types, and pattern matching.

Test-driven development using the RED-GREEN-refactor cycle. Suitable for users who want to build new features or fix bugs with TDD, mention "red-green-refactor", want to use integration testing, or ask about "test-first development".
Apply vertical (domain-first) codebase architecture to any project. Use this skill whenever a user asks where to put a file, how to structure a codebase, how to organize code by feature or domain, how to refactor a "horizontal" structure (components/, hooks/, utils/, types/), or asks about code colocation, monorepo boundaries, shared code, or module ownership. Also trigger when the user creates a new module and needs to decide where it belongs, or when reviewing a PR that touches file organization. Works for any language or framework (Python, TypeScript, Go, Rust, etc.) — not just React or frontend.
Choose and refactor visionOS app architecture across surfaces, scene boundaries, state ownership, and file layout. Use when deciding window vs volume vs immersive space, splitting a feature across scenes, cleaning up a monolithic spatial root, or defining the ownership map before implementing SwiftUI or RealityKit details.
Code quality improvement: review, refactoring, debugging. Phases: review feedback, systematic refactoring, root cause debugging, verification. Capabilities: SOLID/DRY compliance, code smell detection, complexity reduction, bug investigation, verification gates. Actions: review, refactor, debug, verify, validate code. Keywords: code review, refactor, debug, SOLID, DRY, code smell, bug fix, root cause, verification, technical debt, extract method, test failure, completion claim. Use when: reviewing code changes, improving code quality, fixing bugs, reducing technical debt, validating before merge/commit.
Practical Python craftsmanship guidance based on One Python Craftsman. Use when writing, refactoring, or reviewing Python code for naming, branching, data structures, functions, exceptions, loops, decorators, imports, file I/O, edge cases, and modern syntax choices. If the skills set includes friendly-python, suggest invoking it for better Python outcomes.
Language-agnostic coding principles for maintainability, readability, and quality. Use when implementing features, refactoring code, or reviewing code quality.
Simplify and clean code
Specifies the preferred syntax for asynchronous operations using async/await and onMount for component initialization. This results in cleaner and more readable asynchronous code.
Reduce cyclomatic complexity with targeted refactoring strategies
