Draw C4 · shibainu0817 bundle Generate or update an interactive architecture diagram from a codebase — one self-contained HTML file with C4-style drill-down levels, pan and zoom, an inspector, and a step-through player for runtime flows. Use this whenever someone wants to see, draw, map, visualise or document how their code fits together — 'diagram my codebase', 'show me the architecture', 'how does a request flow through this', 'make me a C4 diagram', 'something like IcePanel or Structurizr', or asks to refresh an existing diagram after the code changed. Use it even when the word 'diagram' never appears; any request to map services, containers, components, data stores, queues, dependencies or request paths out of source code belongs here. Also use it when handed an existing architecture plot HTML and asked to change, extend, correct or re-generate it.
