Design systems, services, and architectures. Trigger with "design a system for", "how should we architect", "system design for", "what's the right architecture for", or when the user needs help with API design, data modeling, or service boundaries.
Design scalable distributed systems using structured approaches for load balancing, caching, database scaling, and message queues. Use when the user mentions "system design", "scale this", "high availability", "rate limiter", or "design a URL shortener". Covers common system designs and back-of-the-envelope estimation. For data fundamentals, see ddia-systems. For resilience, see release-it.
Use this skill when designing distributed systems, architecting scalable services, preparing for system design interviews, or making infrastructure decisions. Triggers on load balancing, CAP theorem, sharding, replication, caching strategies, message queues, microservices architecture, database selection, rate limiting, and any task requiring high-level system architecture decisions.
Diagnose design problems and guide architecture decisions for solo developers
Design and architect software systems. Plans system components, interactions, and deployment patterns for scalability and maintainability.
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.
This skill should be used when the user asks to "design interview processes", "create hiring pipelines", "calibrate interview loops", "generate interview questions", "design competency matrices", "analyze interviewer bias", "create scoring rubrics", "build question banks", or "optimize hiring systems". Use for designing role-specific interview loops, competency assessments, and hiring calibration systems.
Use when creating or iterating on a detailed per-subsystem technical design specification from a system spec, before starting OpenSpec workflow. Triggers: "design spec", "subsystem spec", "write the spec for S1", "phase breakdown", "implementation phases", "mid-level spec", "technical design". Encodes opinionated progressive phase discipline with FP progression and contract boundaries. Do NOT use for high-level system specs (use brainstorming) or for OpenSpec artifacts (use openspec directly).
Software architecture and system design - scalability patterns, reliability engineering, and the art of making technical trade-offs that survive productionUse when "system design, architecture, scalability, how should we structure, distributed, microservices, monolith, high availability, design the system, component diagram, architecture, system-design, scalability, reliability, distributed, api, modeling, c4" mentioned.
Generate Technical Architecture Documents (TAD) from PRD files. Use when users ask to "design the architecture", "create a TAD", "system design", or want to define how a product will be built. Creates tad.md with modular architecture optimized for startups.
Agent skill for arch-system-design - invoke with $agent-arch-system-design
Use when planning system architecture to ensure nothing is missed. Provides structured questions covering scalability, security, data, and operational dimensions before implementation.
