Need help deploying sac-c4?
Chalk Labs sets up agents like this inside real teams: connected to your tools, tested on your data, with a human in the loop where it matters.
Install
Works with Claude Code, Claude apps, Codex, Cursor, Gemini CLI, GitHub Copilot, VS Code, OpenCode, Goose, Windsurf. Read the repository before you give any tool access to your data.
npx agentmarket install skill/spillwavesolutions-sac-c4
Asks which of your tools to add it to (Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI, Claude Desktop) and shows the change first. See https://agentmart.dev/cli.

- Skill 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
```bash
# 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
