arc-agent: AI System Design Generator
The arc-agent is a new Go CLI tool designed to streamline the system design process. It allows users to break down design prompts into structured components, producing various YAML artifacts and visual diagrams. This approach facilitates easier review and validation of each design stage, enhancing productivity in system design tasks.
- ▪Arc-agent is a CLI tool that transforms system design prompts into structured workspaces.
- ▪It generates multiple YAML files and diagrams, making the design process more manageable.
- ▪Users can install the CLI and quickly create designs using specific commands.

It is a Go CLI for turning a system design prompt into a real design workspace: requirements, entities, APIs, high-level design, optional deep dives, and architecture diagrams. The core idea is simple: do not ask an agent for one big architecture document and hope it is coherent.
