Detect common code smells and anti-patterns providing feedback on quality issues a senior developer would catch during review. Use when user opens/views code files, asks for code review or quality assessment, mentions code quality/refactoring/improvements, when files contain code smell patterns, or during code review discussions.
Human-readable control flow patterns for refactoring complex conditionals. Use when refactoring nested conditionals, improving code readability, or restructuring decision logic.
Applies TDD workflow to development. Use when writing tests before code, implementing features test-first, fixing bugs via failing test, or refactoring with test coverage. Detects AI anti-patterns.
This skill should be used when fixing bugs, implementing features, debugging issues, or making code changes. Ensures understanding of code flow before implementation by: (1) Tracing execution path with specific file:line references, (2) Creating lightweight text diagrams showing class.method() flows, (3) Verifying understanding with user. Prevents wasted effort from assumptions or guessing. Triggers when users request: bug fixes, feature implementations, refactoring, TDD cycles, debugging, code analysis.
Apply the Tell Don't Ask (TDA) principle when reviewing, writing, or refactoring object-oriented code. Use this skill whenever the user asks about OOP design, mentions getters/setters, wants to review a class for encapsulation issues, asks how to move logic closer to data, or asks why code feels "procedural" despite using classes. Also trigger when the user asks to refactor code that queries an object's state before making decisions externally. This skill should kick in for any code review or design question involving data access patterns, encapsulation, or how objects should collaborate.
Test coverage verification for refactoring. Apply when verifying existing test coverage, identifying gaps, recommending pre-refactoring tests, and defining verification checkpoints.
Write and revamp product documentation to a high editorial standard using Mintlify, with strong information architecture, precise titles/descriptions, parameter-level clarity, cross-linking, and maintainable examples. Use when creating new docs pages, refactoring existing docs, improving docs structure/navigation, or standardizing docs quality across a repository.
Evaluate and improve code modularization using the Balanced Coupling Model. Analyzes coupling strength, connascence types, and distance to identify refactoring opportunities and architectural improvements. Use when reviewing code architecture, refactoring modules, or designing new systems.
Swift/iOS static analysis CLI. Use `depgraph` to find who calls a function, what breaks if you change a file, track call sites and blast radius before refactoring, and map symbol dependencies across files. Use `ask` to consult Swift/iOS/tvOS/watchOS/macOS documentation and best practices.
Full-stack development skill with six-layer architecture, supporting cross-layer modifications initiated from any layer. It automatically coordinates the collaboration of six layers: UI Layer/Frontend Service Layer/Frontend API Layer/Backend API Layer/Backend Service Layer/Data Layer, enabling cross-layer consistent code generation and refactoring. Suitable for Vue3+FastAPI+PostgreSQL tech stack
Use when designing software architecture, refactoring code structure, solving recurring design problems, or when code exhibits symptoms like tight coupling, rigid hierarchies, scattered responsibilities, or difficult-to-test components. Also use when choosing between architectural approaches or reviewing code for structural improvements.
Agent Skill for Swift architecture design and implementation patterns, with architecture-specific playbooks and review checklists. Use when designing new features, refactoring existing modules, reviewing pull requests, or debugging maintainability issues in SwiftUI/UIKit projects and you need concrete guidance for MVVM, MVI, TCA, Clean Architecture, VIPER, or Reactive patterns.
