    Yes, change sets work in both directions. For example, when you add elements or make changes to a diagram, the change set tells the agent exactly what needs to change in the code. You can also enable an instruction for the agent to update the documentation after completing its work, so it reflects what was actually implemented. The goal is to help the agent develop with the full architectural context available through Viaduct’s MCP integration, while also keeping the documentation up to date.

    We built Viaduct to give software teams a free, collaborative C4 modeling tool that also streams the architecture to AI agents via a hosted MCP server. It supports system, container, component and code diagrams, live teamwork, and generates change sets for coding agents. How do you currently keep architecture diagrams in sync with your codebase?
