Ingest Codebase - Mental Model Creation

Create a comprehensive mental model that captures how a system actually works - not just what files exist, but the conceptual boundaries, responsibilities, decisions, and connections that shape it.

When to Use

• Starting a new mental model for a codebase
• The existing model feels incomplete or shallow
• Onboarding to understand a system's architecture
• After major changes to verify the model is still accurate

Philosophy

A good domain model answers:

• "What are the core things this system deals with?" → Domains
• "What can this system do?" → Capabilities (with --operates-on connections!)
• "What concerns cut across multiple parts?" → Aspects (with --applies-to connections!)
• "Why was it built this way?" → Decisions
