Analyzes events through computer science lens using computational complexity, algorithms, data structures, systems architecture, information theory, and software engineering principles to evaluate feasibility, scalability, security. Provides insights on algorithmic efficiency, system design, computational limits, data management, and technical trade-offs. Use when: Technology evaluation, system architecture, algorithm design, scalability analysis, security assessment. Evaluates: Computational complexity, algorithmic efficiency, system architecture, scalability, data integrity, security.
Visualize and document pplx-sdk system architecture with Mermaid diagrams — layer maps, data flow, dependency graphs, sequence diagrams, and component relationships. Use when designing new features, onboarding, or documenting how the system works.
Explain how code works in detail. Use when trying to understand unfamiliar code, complex logic, or system architecture.
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.
Create detailed technical specifications, requirements documents, design documents, and system architecture specs. Use when writing technical specs, requirements docs, or design documents.
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.
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.
Agent skill for arch-system-design - invoke with $agent-arch-system-design
Transform approved requirements into comprehensive technical designs. Define system architecture, component interactions, data models, and interfaces to create a blueprint for implementation.
Generate Excalidraw diagrams from natural language descriptions. Use when asked to "create a diagram", "make a flowchart", "visualize a process", "draw a system architecture", "create a mind map", or "generate an Excalidraw file". Supports flowcharts, relationship diagrams, mind maps, and system architecture diagrams. Outputs .excalidraw JSON files that can be opened directly in Excalidraw.
Design system architecture and high-level technical strategy
Explain a piece of code, a subsystem, or an architectural concept in the codebase, grounded in real files. Use when user says 'explain this', 'walk me through X', 'how does Y work', 'what does this module do', 'help me understand the Z flow', or 'onboard me on this component'. Do NOT use for writing permanent docs (use write-doc or arc42) or for code review (use review-diff).
