What is the System Design skill for Claude Code?

It is a specialized capability that provides a structured workflow for Claude to help you design software architectures, APIs, and data models with validation steps.

Can I use this skill to write actual code?

This skill is specifically optimized for the design and specification phase. For actual coding tasks, it is recommended to switch to an implementation-focused workflow.

How does it handle design validation?

The skill follows a specific workflow that gathers requirements and constraints first, then validates the proposed architecture against those constraints to ensure technical feasibility.

What kind of outputs does the System Design skill generate?

It produces professional design specifications, architectural diagrams, data schemas, and validation notes that can be used as blueprints for development.
