Understand Project Structure

Use this skill when starting work on a LikeC4 project or before making significant changes.

C4 Framework Foundation

Before understanding the project, familiarize yourself with the C4 model:

• Read the c4-modeling-process skill to understand the methodology
• Understand how architecture is organized: C1 Context → C2 Container → C3 Component
• This project follows these conventions for all models

Workspace Structure

• Shared specifications: projects/shared/spec-*.c4 - Source of truth for element kinds, relationship types, and tags
• MCP servers (REQUIRED): Use LikeC4 MCP and Context7 MCP for context gathering
• ADR documentation: ADR/ directory - System architecture decisions using standard ADR format

Steps

1. C4 Context (REQUIRED): Read c4-modeling-process skill to understand design hierarchy
2. Use LikeC4 MCP (REQUIRED): list-projects or read-project-summary to get project overview
3. Read likec4.config.json to understand includes and image aliases
4. Check projects/shared/spec-*.c4 for available element kinds, relationship types, and tags
5. Review existing model files to understand current C1/C2/C3 architecture
6. Use Context7 MCP: Query LikeC4 documentation if uncertain about syntax or features

Output

• Understanding of C4 framework and top-to-bottom design approach
• Complete understanding of project structure and architecture
• Available element kinds, relationship types, and tags
• Current C1/C2/C3 architecture organization
