sdd-plan
Plan-first development methodology that creates detailed specifications before coding. Creates structured plans with phases, file-level details, and verification steps. Includes automatic AI review, modification application, and validation.
architect
아키텍처, 설계, 시스템 설계, 구조 설계, 레이어 설계 - Use when designing systems, layer structures, or module boundaries. Architecture design guide based on Clean Architecture and DDD principles.
software-architecture
Guide for quality focused software architecture. This skill should be used when users want to write code, design architecture, analyze code, in any case that relates to software development.
system-design
Use when designing, architecting, or planning a new system from requirements or ideas - transforms concepts into navigable design catalog using EventStorming methodology, Mermaid diagrams, and progressive elaboration through 5 phases (Requirements, Big Picture, Processes, Data/Flows, Integration)
project-planner
Comprehensive project planning and documentation generator for software projects. Creates structured requirements documents, system design documents, and task breakdown plans with implementation tracking. Use when starting a new project, defining specifications, creating technical designs, or breaking down complex systems into implementable tasks. Supports user story format, acceptance criteria, component design, API specifications, and hierarchical task decomposition with requirement traceability.
elixir-scribe
Single Responsibility Code in Self-Documented Folder Structure
codebase-learn
Learn and remember codebase structure to minimize future token usage. Records architectural knowledge, file purposes, and patterns as a connected graph.
workbench-architecture
Architecture and ADR workflows for Workbench CLI. Use when documenting system design, decisions, tradeoffs, or rationale that must be tracked over time.
system-design
Use when designing system architecture, APIs, components, or data models - provides a structured design workflow with validation and documentation outputs.
architecture-patterns
Implement proven backend architecture patterns including Clean Architecture, Hexagonal Architecture, and Domain-Driven Design. Use when architecting complex backend systems or refactoring existing applications for better maintainability.
senior-architect
Comprehensive software architecture skill for designing scalable, maintainable systems using ReactJS, NextJS, NodeJS, Express, React Native, Swift, Kotlin, Flutter, Postgres, GraphQL, Go, Python. Includes architecture diagram generation, system design patterns, tech stack decision frameworks, and dependency analysis. Use when designing system architecture, making technical decisions, creating architecture diagrams, evaluating trade-offs, or defining integration patterns.
code-standards
Expert in code design standards including SOLID principles, Clean Code patterns (KISS, YAGNI, DRY, TDA), and pragmatic software design. **ALWAYS use when designing ANY classes/modules, implementing features, fixing bugs, refactoring code, or writing functions.** Use proactively to ensure proper design, separation of concerns, simplicity, and maintainability. Examples - "create class", "design module", "implement feature", "refactor code", "fix bug", "is this too complex", "apply SOLID", "keep it simple", "avoid over-engineering".
system-design
System design, software architecture, API design, cybersecurity, and threat modeling. Build secure, scalable systems.
domain-driven-design
Model business domains using DDD tactical and strategic patterns
solid-principles
Apply and validate SOLID principles in object-oriented design
design-patterns
Identify, implement, and teach GoF design patterns
architecture-patterns
Design, evaluate, and document software architecture patterns
technical-decision-making
Master technical decision-making, architecture choices, technology evaluation, and technical roadmaps for engineering teams
diagram
Maintain and synchronize Unified Impact Diagrams following Diagram Driven Development (DDD) methodology. Create, update, and manage diagrams that connect user value to technical implementation.
