Zindex – Diagram Infrastructure for Agents

# zindex - diagram infrastructure for agents Source: [https://zindex.ai/](https://zindex.ai/) Agents create, edit, validate, and render diagrams as durable state \- not throwaway output\. Structured operations, immutable revisions, 40\+ validation rules, and multiple render targets through the Diagram Scene Protocol \(DSP\)\. zindex architecture agentDSPzindexvalidatenormalizescenelayoutrenderSVGPNG ``` { "schemaVersion": "0.1", "scene": { "id": "payments-arch", "units": "px" }, "elements": [ { "id": "api", "kind": "node", "nodeType": "service", "shape": "roundedRect", "label": "API Gateway" }, { "id": "queue", "kind": "node", "nodeType": "queue", "label": "Job Queue" }, { "id": "e1", "kind": "edge", "from": { "elementId": "api" }, "to": { "elementId": "queue" }, "router": "orthogonal" } ] } ``` ### Semantic, not geometric Agents declare nodes, edges, and relationships\. Layout is computed, not hand\-placed\. ### Layout engine built in A Sugiyama\-style hierarchical layout pipeline figures out positions, edge routes, and label placement automatically\. Agents describe the graph; the engine handles the geometry\. ### Patchable Stable IDs enable incremental updates\. Add a node, move an edge \- without regenerating the entire diagram\. ### Renderer\-agnostic One canonical scene, multiple outputs: SVG and PNG with 4 render themes \(clean, dark, blueprint, sketch\)\. ### Deterministic Same input, same output\. Validate → normalize → layout → render\. Every step is inspectable\. 01 ### Incremental editing Patch\-based updates instead of full regeneration\. Agents can modify individual elements while preserving the rest\. 02 ### Deterministic execution Consistent output across runs\. Failures are explainable\. The pipeline is inspectable at every step\. 03 ### Durable state Revision history, diffs, stable IDs\. Diagrams are versioned artifacts, not ephemeral outputs\. 04 ### Multi\-agent ready Shared infrastructure for multiple agents collaborating on diagrams\. Not just a single\-shot generator\. 05 ### Domain\-aware Purpose\-built for architecture, BPMN workflows, ER diagrams, sequence diagrams, org charts, and network topology \- not generic vector shapes\. 06 ### Production\-grade 17 operation types\. 40\+ semantic validation rules\. Auth, rate limiting, PostgreSQL storage\. agents / LLMsdecide what should change zindexapply changes through DSP protocol renderersdisplay the result Zindex is to diagrams what a database is to application state\. The agent\-native runtime for creating, updating, validating, and rendering diagrams as durable state\.
