design-architecture

From the author

Reviews the current codebase architecture and proposes improvements using four parallel specialist subagents: System Architect, Software Architect, Data Architect, and an Adversarial Architect that red-teams failure paths, LLM adversarial output scenarios, silent corruption risks, and invariant bypasses. Each subagent independently analyzes the codebase from their domain perspective, then their findings are consolidated into a living `architecture.md` file with a tracked to-do list and change log. Use this skill whenever the user asks to review, analyze, audit, or improve the architecture — or when they ask questions like "what should we change structurally?", "how is the system organized?", "what are our architecture problems?", "can you do an architecture review?", or "let's redesign X". Also trigger when the user mentions technical debt, structural improvements, security concerns, failure modes, vulnerabilities, or wants a second opinion on design decisions, even if they don't use the word "architecture".
