color-palette

Extracts dominant colors from an image file and returns HEX and RGB values per color. Supports up to 20 colors per extraction. Can optionally generate a swatch PNG showing the palette.

map-grabber

Fetches OpenStreetMap street networks and building footprints for a given address and exports them as SVG, GeoPackage, or DXF vector files. Designed for architects and urban designers who need georeferenced site base maps for CAD or Rhino workflows.

svg-to-image

Converts SVG files to PNG or JPG using cairosvg and Pillow. Supports custom output dimensions and DPI. Works with OpenClaw's media delivery pipeline to send generated images directly in conversation.

sun-path

Calculates solar position, generates sun path diagrams, and simulates 2D building shadows for any location and time. Also computes annual sun and shadow hours at a given point, processes terrain shadow from GeoTIFF DEMs, and plots thermal comfort on a psychrometric chart.

wind-site

Fetches wind rose and current or recent wind data (speed and direction) for any location by latitude and longitude. Uses the Open-Meteo API, which requires no key or account. Provides site wind climate data as input for CFD or wind-tunnel studies; does not run simulations itself.
