What problem does it solve? Producing architecture, workflow, and sequence diagrams that are structurally correct, visually clean, and faithful to source references is error-prone, especially when recreating existing diagrams or validating Mermaid output before delivery. ## Core Features & Use Cases - Diagram Classification and Planning: Classifies each task as semantic, inspired-by-reference, or recreation, and builds a diagram contract covering nodes, groups, relationships, and connector endpoints before drawing. - Visual QA and Layout Reflow: Runs post-render checks for container sizing, text fit, connector anchors, label separation, z-order, and crossing aesthetics, with global reflow after every correction. - Mermaid Lint Validation: Validates Mermaid files with orchestra diagrams lint and attaches lint evidence to workflow tasks. - Use Case: An architect recreating a draw.io system diagram inventories every source element, renders the diagram, runs a pixel-fidelity QA pass against the reference, and delivers the editable source plus render with QA evidence. ## Quick Start Ask the assistant to create a Mermaid sequence diagram for your service authentication flow and lint it before sharing.
