SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Reads a codebase or system description and produces a clear, structured architecture overview with diagrams. It maps out layers, major components, data flows, and external dependencies, then renders ASCII diagrams showing how the pieces connect. The result is a document a new engineer could read in 10 minutes and understand how the system works.

Core Features & Use Cases

  • Map layers, major components, data flows, and external dependencies
  • Render ASCII diagrams showing how components connect
  • Useful for onboarding, architecture reviews, documenting inherited systems, and clarifying mental models before refactors

Quick Start

Ask the Architecture Explainer to document the entire repository's architecture with an ASCII diagram.

Frequently Asked Questions about Architecture Explainer

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate architecture documentation from an existing codebase?

Generate architecture documentation by submitting the codebase or a system description for analysis. The tool maps layers, components, data flows, and external dependencies, then renders ASCII diagrams to visually communicate the system structure.

What is the best way to visualize system design for onboarding new engineers?

Visualize system design by translating the codebase into structured architecture blueprints with ASCII diagrams. This maps components and data flows, producing a clear 10-minute overview document for new engineers to quickly understand the system.

Can I document inherited system architecture without prior documentation?

Document inherited system architecture by reading the existing codebase to identify layers, components, and external dependencies. The tool generates a structured overview and visual diagrams, clarifying the mental model of undocumented systems.

How does mapping data flows and components help with planning refactors?

Mapping data flows and components clarifies the existing architecture before refactoring. By rendering connections in ASCII diagrams, it exposes structural layers and dependencies, ensuring you fully understand the system's current state before modifying it.

Do I need to provide external dependency details for an architecture review?

Provide the codebase or system description, and the tool automatically identifies external dependencies. It maps these connections alongside internal layers and data flows, rendering a complete architecture overview suitable for formal reviews.

Can I use ASCII diagrams to document system architecture, or do I need graphical rendering?

ASCII diagrams effectively document system architecture without graphical rendering. The tool generates text-based diagrams showing how layers, components, and data flows connect, ensuring the architecture documentation is easily readable in any environment.
