The Agent Skills Directory

[SAFE]: The skill serves as a technical reference for GIS developers working with the PyQGIS API. It demonstrates proper usage of QgsCoordinateReferenceSystem, QgsCoordinateTransform, and QgsCoordinateTransformContext, following official security and accuracy best practices.
[DATA_INGESTION_SURFACE]: The skill defines patterns for loading and processing external GIS data formats (e.g., Shapefiles, GeoPackages, CSVs) through QgsVectorLayer. This constitutes a standard data ingestion surface for the intended use case.
Ingestion points: QgsVectorLayer initialization in SKILL.md and references/examples.md.
Boundary markers: N/A (Standard library calls).
Capability inventory: Use of processing.run, geometry.transform, and layer.setCrs for data manipulation.
Sanitization: The instructions emphasize validating coordinate ranges and CRS validity (isValid()) before proceeding with transformations, which serves as technical data validation.
