What C4 views does it cover?

It covers context diagrams, container mapping, and component synthesis, all built on a bottom-up analysis of the code.

How are the diagrams produced?

The agent analyzes the codebase bottom-up and synthesizes the component, container, and context views from that analysis.

Do I need existing architecture documentation to use it?

No. The workflow starts from analysis of the codebase itself and builds the C4 documentation from there.

What kind of tool is this?

It is a plugin for AI agents that adds a C4 architecture documentation workflow to what the agent can do.

c4-architecture

PackDocs & knowledge

c4-architecture is a plugin that gives an AI agent a workflow for producing C4 architecture documentation. It starts with a bottom-up analysis of the codebase, then synthesizes components, maps containers, and generates context diagrams. The result is C4 software architecture diagrams built from the code itself.

Unavailable. Delivery for this kind is on the roadmap — not serving yet.

Have an AI agent that supports installing plugins.

What your AI can do with it

Analyzes a codebase bottom-up as the starting point of the C4 workflow
Synthesizes component-level views from the code analysis
Maps the containers that make up the system
Generates a context diagram for the system
Produces C4 software architecture diagrams from the codebase
Runs a complete C4 documentation workflow end to end

Getting started

Have an AI agent that supports installing plugins.
Install the c4-architecture plugin for that agent.
Point the agent at the codebase you want documented.
Ask the agent to run the C4 workflow to generate context, container, and component views.
