## What it does

The plugin documents system architecture using the C4 model from the ground up. It inspects existing source code first, then synthesizes components and maps them into containers. Context diagrams finish the sequence.

The entire workflow handles C4 architecture documentation step by step. Because analysis runs bottom-up directly from the codebase, the resulting architecture maps reflect concrete implementation files.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add wshobson/agents
```
In the agent chat (not a shell):
```text
/plugin install c4-architecture@claude-code-workflows
```

## When to use it
- analyze codebase structure from the bottom up
- synthesize components directly from source code
- map identified components to system containers
- generate C4 context diagrams

## Example prompts
- Run a bottom-up code analysis and synthesize components for C4 architecture
- Map components to system containers and generate a context diagram
