mbuyco System Design Skill
Overview
This skill enables the agent to perform robust system design reasoning with explicit attention to quality attributes: performance, scalability, reliability, and security.
When to use
Activate this skill when the task involves:
- Designing a system architecture
- Evaluating design trade-offs (performance vs cost vs complexity)
- Recommending architectural patterns
- Identifying non-functional requirements
Instructions
- Start by identifying the contextual constraints (scale, latency, consistency, security requirements).
- Enumerate system components and interactions.
- For each major quality attribute (performance, reliability, security), provide explicit reasoning on trade-offs.
- Recommend patterns (e.g., microservices, event-driven, caching strategies) and justify selection.
- Produce a structured design document (sections: Overview, Requirements, Components, Quality Attribute Analysis, Diagrams/References).
Examples
Input: “Design a scalable document search system for 10M users with sub-second queries and secure access controls.”
Output:
- Requirements breakdown
- Quality attribute analysis
- Suggested architecture pattern
- Estimated throughput/latency
Edge Cases
- Conflicting non-functional requirements
- Undefined performance constraints
