Generate comprehensive C4 architecture documentation for an existing repository/codebase using a bottom-up analysis approach.
Create comprehensive HTML architecture diagrams showing data flows, business objectives, features, technical architecture, and deployment. Use when users request system architecture, project documentation, high-level overviews, or technical specifications.
Master of text-based visual communication using ASCII art, Unicode box-drawing, and structured diagram notation. Creates clear, maintainable diagrams for systems, processes, hierarchies, relationships, and psychological structures. Proactively generates diagrams to enhance understanding. Activate on visualization needs, system architecture, process flows, psychological mapping, or when complex concepts would benefit from visual representation. NOT for photo editing, vector graphics, or GUI-based design tools.

Design system architecture and high-level technical strategy
Explain how code works in detail. Use when trying to understand unfamiliar code, complex logic, or system architecture.
Creates professional logical flow diagrams and logical system architecture diagrams using draw.io XML format (.drawio files). Use when creating: (1) logical flow diagrams showing data/process flow between system components, (2) logical architecture diagrams representing system structure without cloud provider specifics, (3) BPMN process diagrams, (4) UML diagrams (class, sequence, activity), (5) data flow diagrams (DFD), (6) decision flowcharts, or (7) system interaction diagrams. This skill focuses on generic/abstract representations, not AWS/Azure-specific architectures (use aws-drawio-architecture-diagrams for cloud diagrams).
This skill should be used when the user asks to "generate design document", "create database schema", "design API interface", "draw flowchart", "create sequence diagram", "design system architecture", "design module structure", "create data flow diagram", or mentions technical design documentation. Generates comprehensive technical design documents with database schemas, API specs, and Mermaid diagrams.
System Architect that creates parallelizable PRDs with junior-proof technical specs. Use when planning features, designing implementations, or when the user says 'plan', 'architect', 'design', or 'PRD'. Outputs PRDs organized in Priority groups where tasks within each group can be executed in parallel by independent dev subagents (ralph). Each user story includes file ownership, technical specs, and acceptance criteria detailed enough for a Sonnet-class model to implement without clarification.
Consult this skill when designing client-server systems or API architectures. Use when traditional web/mobile applications with centralized services, clear separation between client and server responsibilities needed. Do not use when selecting from multiple paradigms - use architecture-paradigms first. DO NOT use when: peer-to-peer dominates - consider dedicated P2P patterns.
Transform approved requirements into comprehensive technical designs. Define system architecture, component interactions, data models, and interfaces to create a blueprint for implementation.
Use when designing system architecture, making high-level technical decisions, or planning major system changes. Focuses on structure, patterns, and long-term strategy.
