sac-c4

name	sac-c4
description	C4 model integration for the architecture second brain. Map System/Person/ SoftwareContainer/Component/Code, generate L1–L4 Mermaid views, import Structurizr DSL, and avoid Docker vs C4 Container confusion.

SAC × C4 model

Critical naming

• C4 Container = SoftwareContainer (or Service/WebApp/Database stand-ins)
• Docker/OCI = ContainerImage — different concept

Commands

# Inventory how the bundle maps to C4 abstractions
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/sac_c4.py" --bundle knowledge --inventory

# Generate L1–L4 diagram concepts + Structurizr DSL export
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/sac_c4.py" --bundle knowledge --generate --system "My System"

# Print DSL only
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/sac_c4.py" --bundle knowledge --dsl

# Scan existing Structurizr workspaces
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/sac_scan_structurizr.py" --root . --json

When designing

1. L1 — who uses the system; external systems
2. L2 — where does the new app/service/DB sit as a SoftwareContainer?
3. L3 — components inside that container
4. L4 — modules/classes when coding
