System Design

Overview

Create clear system, API, component, or data model designs with explicit requirements, constraints, and validation steps.

When to Use

  • Designing system architecture or components
  • Specifying APIs or data models
  • Producing design docs or diagrams

Avoid when:

  • You only need implementation tasks (use implementation-workflow)

Quick Reference

Task Load reference
System design workflow skills/system-design/references/system.md

Workflow

  1. Gather requirements and constraints.
  2. Load the system design reference.
  3. Define structure, interfaces, and data flows.
  4. Validate against constraints and best practices.
  5. Deliver spec/diagram/code artifacts.

Output

  • Design spec or diagram
  • Validation notes and follow-ups

Common Mistakes

  • Designing without constraints
  • Mixing implementation details with spec scope
