ALWAYS prefer primary sources (dependent skill packages) over external documentation
ALWAYS verify integration patterns against BOTH technology sides
NEVER rely on unofficial tutorials without cross-checking against official docs
ALWAYS cite specific versions when referencing technology capabilities
ALWAYS verify CRS codes against the EPSG registry
