SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides an intelligent entry point for interacting with C3 architecture documentation. It guides users, whether they are new to the project or need specific information, ensuring quick orientation and efficient information retrieval.

Core Features & Use Cases

  • Automatic .c3/ Detection: Automatically checks for existing C3 documentation and offers to initialize it if missing.
  • TOC-Driven Inventory: Presents a comprehensive overview of the architecture (stats, container summaries, ADRs) derived from the Table of Contents.
  • Intelligent Presentation: Adapts its output based on user intent, offering general orientation, focused exploration of specific areas, or a history of architectural decisions.
  • Navigation Support: Facilitates drilling down into specific containers, viewing components, or understanding ADRs with simple commands.
  • Adoption Offer: If no C3 documentation is found, it proactively suggests using the c3-adopt skill to set it up.
  • Use Case: A new team member wants to understand the project's architecture. They use c3-use to get a high-level overview, then drill down into specific containers and components as needed, without prior knowledge of the file structure.

Quick Start

Use the c3-use skill to get an overview of the project's architecture.
