Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00111 | $0.02827 |
| Opus 5 | $0.00056 | $0.01413 |
| Sonnet 5 | $0.00022 | $0.00565 |
| Haiku 4.5 | $0.00011 | $0.00283 |
Grade A, and why
qgis-core-data-providers scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Quick Reference
Provider System Overview
QGIS uses a plugin-based provider architecture. Providers are registered in QgsProviderRegistry and loaded during QgsApplication.initQgis(). Each provider handles one or more data formats.
| Provider Key | Type | Formats |
|---|---|---|
"ogr" |
Vector | Shapefile, GeoPackage, GeoJSON, FlatGeoBuf, KML, DXF, GPX |
"postgres" |
Vector | PostGIS tables and views |
"spatialite" |
Vector | SpatiaLite databases |
"memory" |
Vector | In-memory temporary layers |
"delimitedtext" |
Vector | CSV, TSV, custom-delimited text files |
"WFS" |
Vector | OGC Web Feature Service |
"virtual" |
Vector | SQL queries across loaded layers |
"gdal" |
Raster | GeoTIFF, JPEG2000, COG, VRT, GeoPackage raster |
"wms" |
Raster | WMS, WMTS, XYZ tiles |
"wcs" |
Raster | OGC Web Coverage Service |
"postgresraster" |
Raster | PostGIS raster tables |
"pdal" |
Point Cloud | LAS, LAZ (QGIS 3.18+) |
"copc" |
Point Cloud | Cloud Optimized Point Cloud (QGIS 3.26+) |
"ept" |
Point Cloud | Entwine Point Tile (QGIS 3.18+) |
"mdal" |
Mesh | NetCDF, GRIB, XMDF, DAT |
"vectortile" |
Vector Tile | Mapbox Vector Tiles (MVT) |
"cesiumtiles" |
Tiled Scene | Cesium 3D Tiles (QGIS 3.34+) |
Layer Construction Pattern
# Vector layer
vlayer = QgsVectorLayer(data_source_uri, display_name, provider_key)
# Raster layer
rlayer = QgsRasterLayer(data_source_uri, display_name, provider_key)
# Point cloud layer (QGIS 3.18+)
pclayer = QgsPointCloudLayer(data_source_uri, display_name, provider_key)
# Mesh layer
mlayer = QgsMeshLayer(data_source_uri, display_name, provider_key)
# Vector tile layer
vtlayer = QgsVectorTileLayer(data_source_uri, display_name)
ALWAYS check validity immediately after creation:
layer = QgsVectorLayer(uri, name, provider)
if not layer.isValid():
raise RuntimeError(f"Failed to load layer '{name}' from: {uri}")
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

qgis-core-data-providers is a skill published in the GitHub repository Impertio-Studio/QGIS-Claude-Skill-Package (33 stars, last pushed 2mo ago), licensed MIT. It adds 111 tokens to every session and 2,827 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
