About this plugin
The plugin turns a codebase into C4 architecture documentation through a bottom-up workflow. It analyses the code, synthesises components, maps them to containers, and generates a context diagram showing the system and its surrounding dependencies.
Run the /c4-architecture command when you need to document an existing system or bring architecture views into line with the implementation. The workflow is split across agents for code analysis, component synthesis, container mapping, and context modelling.
