Router Setup (Data Mode):

These are idiomatic FastAPI patterns that may appear problematic but are correct:

Interactive node-based graph visualization and workflow editor for React applications. \n \n Provides built-in node types (default, input, output, group) and edge types (bezier, straight, step, smoothstep) with full customization via custom components \n Includes Handle components for connection points, NodeProps and EdgeProps for typed custom nodes and edges, and EdgeLabelRenderer for interactive labels \n Offers programmatic control through useReactFlow hook for viewport management (fitView, z

Catches common bugs in LangGraph state management, graph structure, and async patterns. \n \n Identifies 20+ critical issues including state mutations, missing reducers, invalid conditional edge returns, and checkpointer configuration errors \n Covers state schema problems like improper use of add_messages , full-state returns, and Pydantic models without annotations \n Detects graph structure issues: missing entry points, unreachable nodes, incomplete conditional paths, and undeclared Command d

Recommendation: Use TypedDict for most cases. Use Pydantic when you need validation or complex nested structures.

LangGraph builds stateful, multi-actor agent applications using a graph-based architecture:

CSS-first Tailwind v4 configuration using @theme directives, OKLCH colors, and design tokens without config files. \n \n Configure theme entirely in CSS via @theme directives (default, inline, or reference modes) instead of tailwind.config.js \n Use OKLCH color format for perceptually uniform colors with L (lightness), C (chroma), and H (hue) parameters \n Vite plugin setup (@tailwindcss/vite) replaces PostCSS; no postcss.config.js needed \n CSS variable naming conventions for colors, spacing, f

Generate Architectural Decision Records (ADRs) following the MADR template with systematic completeness checking.

Fix: Use @agent.tool if you need context:

See ADDITIONAL_COMPONENTS.md for MiniMap, Controls, Background, NodeToolbar, NodeResizer.

Implication: Core logic is framework-agnostic. When contributing or debugging, check if issue is in @xyflow/system or framework-specific package.

Docling is a document parsing library that converts PDFs, Word documents, PowerPoint, images, and other formats into structured data with advanced layout understanding.

These patterns are intentional and correct - do not report as issues:

Problem: Causes all nodes to re-mount on every render.

Model strings follow provider:model-name format:

This creates a components.json configuration file and sets up:
