ALWAYS LOAD WHEN WORKING WITH PYSIDE6, QT, OR DESKTOP GUI CODE. PySide6 desktop apps: Manager→Service→Wrapper architecture, qasync integration, signals, system tray, testing.
[Planning] ⚡⚡ Brainstorm a feature
Language-agnostic SOLID principles and DDD tactical patterns. Trigger: Always loaded for non-documentation code changes via sdd-apply.
Translate approved GDDs + architecture into epics — one epic per architectural module. Defines scope, governing ADRs, engine risk, and untraced requirements. Does NOT break into stories — run /create-stories [epic-slug] after each epic is created.
Phase d'architecture systématique AVANT le code (TDD). Use when starting a new feature that touches multiple files, designing a new module, or making non-trivial architectural choices.
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.
Comprehensive guide for production-ready Python backend development and software architecture at scale. Use when designing APIs, building backend services, creating microservices, structuring Python projects, implementing database patterns, writing async code, or any Python backend/server-side development task. Covers Clean Architecture, Domain-Driven Design, Event-Driven Architecture, FastAPI/Django patterns, database design, caching strategies, observability, security, testing strategies, and deployment patterns for high-scale production systems.
Guide architectural design decisions for software systems. Use this skill when designing new systems, evaluating architecture trade-offs, or creating technical design documents. Helps produce clear, well-structured design artifacts including component diagrams, data flow, and decision records.
Implements the Chain of Responsibility pattern in Python. Use when the user mentions chain of responsibility, CoR, or when you need to chain handlers that each process and pass to the next—validation pipelines, processing steps, transformation chains, or any sequential pipeline.
Builds and maintains software architecture as code with LikeC4 DSL. Use when requests mention architecture diagrams, C4 context/container/component views, system landscapes, dependency maps, integration maps, or architecture generated from code. Applies to creating new `.c4`/`.likec4` models, updating existing models, validating with LikeC4 CLI, and preparing preview/build/export outputs.
Comprehensive skill for all 26 Gang of Four design patterns with PHP 8.3+ implementations. Covers creational (Abstract Factory, Builder, Factory Method, Prototype, Singleton), structural (Adapter, Bridge, Composite, Decorator, Facade, Flyweight, Proxy), and behavioral patterns (Chain of Responsibility, Command, Interpreter, Iterator, Mediator, Memento, Observer, State, Strategy, Template Method, Visitor) plus Null Object, Object Pool, and Private Class Data.
Use when designing, planning, implementing, or reviewing any non-trivial change — enforces small, focused modules so any change fits in context without compaction
