btp-diagram-generator

BTP Solution Diagram Generator

Produces a .drawio file in the workspace that conforms to the SAP BTP Solution Diagram guidelines and opens it through whichever draw.io MCP server is configured.

⚡ Quick Path (use this first)

For the vast majority of diagrams, do not hand-write XML. Use the btp_builder Python package — it owns icon lookup, SAP palette, port pinning, label HTML, A4 sizing, SVG upscaling, and validation. A typical L1 diagram is ~20 lines.

# scripts/examples/task_center_arch.py — runnable end-to-end
import sys
from pathlib import Path
# Add the skill's scripts/ dir to sys.path so `btp_builder` imports work
# regardless of where the skill is installed
sys.path.insert(0, str(Path(__file__).resolve().parent.parent))
