Agent

Autonomous component that iterates independently using its own LLM client

C4 Model

Context, Containers, Components, Code - hierarchical architecture diagram approach

Context Efficiency

Minimizing token consumption in parent LLM conversations

Feedback Loop

Iterative process: generate → validate → analyze → refine

Headless Mode

Non-interactive operation suitable for CI/CD pipelines

Kroki

Unified API for creating diagrams from textual descriptions (PlantUML, Mermaid, etc.)

Kroki Fat-JAR

Self-contained Java archive (~80MB) running complete Kroki service locally

LiteLLM

Python library providing unified interface to 100+ LLM providers

MCP (Model Context Protocol)

Standard protocol for exposing tools to LLMs via HTTP/SSE

Vision Model

LLM capable of analyzing images (e.g., Claude Sonnet with vision, GPT-4V)

PlantUML

Text-based diagram syntax, particularly popular for UML and architecture diagrams

Syntax Validation

Checking if diagram source code is valid for the target renderer

Design Analysis

Vision-based evaluation of diagram layout, clarity, and conventions

URL Reference

Returning short URL instead of file path or base64 data to save context

Remote Confirmation

Interactive consent before sending data to remote services

SSE (Server-Sent Events)

HTTP protocol for server-to-client streaming, used in MCP

Iteration Limit

Maximum number of refinement cycles before returning current result

Example Provider

Component managing curated sample diagrams for each type
