Ask your coding agent to diagram a codebase, a system, a process or a request. It writes a small typed JSON, stackmap validates it with repair hints the agent acts on, lays it out, and delivers one self-contained HTML viewer. No server, no account, nothing to install to open it.

The agent writes `.stackmap//diagram.json`, validates and repairs it, and delivers `.stackmap//diagram.html`. Open that file in any browser. To change the diagram, ask again: the agent edits the JSON and delivers it again. The viewer itself is read-only.

- **Nodes:** nine types set the colour (`client`, `gateway`, `service`, `database`, `cache`, `queue`, `storage`, `external`, `security`), and lifecycles have seven state types. Cards can add rows, stats, a footer, a link and one of 146 [Simple Icons](https://simpleicons.org) logos.
- **Edges** can be `async` or a `return`, with a `tone` for the main path, security crossings and failure paths.
- **No coordinates:** stackmap lays everything out, with [ELK](https://eclipse.dev/elk/) for architecture and dataflow and its own layout for lanes and sequences.
