Security Scan

The skill's code, instructions, and requested resources are consistent with a CLI that queries the City of Lethbridge ArcGIS/Open Data portal; it does not request credentials or unusual system access.

Purpose & Capability

The name/description say it queries Lethbridge open data via ArcGIS Hub and the code and SKILL.md implement exactly that: catalog/DCAT reads, ArcGIS REST queries, and document download handling. There are no unrelated credentials, binaries, or config paths requested.

Instruction Scope

SKILL.md instructs running the included Python CLI to search/list/info/fetch/download datasets from opendata.lethbridge.ca. The runtime instructions and the script operate only on the portal and ArcGIS endpoints; they do not attempt to read unrelated system files or environment variables.

Install Mechanism

This is an instruction-only skill with a single Python script and no install spec. No external downloads or package installs are performed by the skill itself, minimizing install-time risk.

Credentials

The skill declares no required environment variables or credentials. The code does not access any environment secrets; it only performs HTTP(S) requests to the open data portal and related ArcGIS endpoints.

Persistence & Privilege

The skill does not request always:true and is user-invocable. It creates a local .cache directory next to the script to cache the DCAT catalog (expected for performance) but does not attempt to modify other skills or system settings.

Assessment

This skill appears to do what it says: query the City of Lethbridge open data portal and ArcGIS services. Before installing, be aware it will make network requests to opendata.lethbridge.ca, gis.lethbridge.ca and arcgis.com and will create a local .cache directory next to the script to store the catalog. If you plan to run fetch/download on large datasets, expect potentially large network downloads and disk usage. If you need additional assurance, inspect the remainder of the truncated fetch/download handler to confirm it only downloads public dataset files and does not follow or post to unexpected endpoints. Run the script in a controlled environment (or sandbox) if you are running it for the first time.

Access and analyze 123+ open datasets from the City of Lethbridge via ArcGIS Hub. Data covers transit, infrastructure, elections, environment, tourism, and more.

Quick Start

# Search for datasets
python3 scripts/lethbridge_data.py search "traffic"

# List all datasets
python3 scripts/lethbridge_data.py list

# View dataset info
python3 scripts/lethbridge_data.py info "Traffic Counts"

# Fetch data from ArcGIS feature service
python3 scripts/lethbridge_data.py fetch "Traffic Counts" --limit 5

# Fetch with field filter
python3 scripts/lethbridge_data.py fetch "Intersection Safety Devices" --limit 10 --format json

# Export as CSV
python3 scripts/lethbridge_data.py fetch "City Boundary" --csv

# List all datasets with download links
python3 scripts/lethbridge_data.py downloads

Commands Reference

Command	Description
search <query>	Search datasets by keyword
list	List all datasets
info <name-or-id>	Show dataset metadata and data source
fetch <name-or-id>	Fetch data (opts: --limit, --format json/csv, --csv)
downloads	List datasets with direct file download URLs

Data Sources

Lethbridge datasets come in three types:

1. ArcGIS Feature Services — Queryable geospatial data (parks, streets, boundaries)
2. ArcGIS Map Services — Read-only map layers
3. Document Links — Direct file downloads (Excel, CSV, PDF)

The CLI auto-detects the source type and uses the appropriate method.

ArcGIS REST API

Geospatial datasets use the ArcGIS REST query API:

• Endpoint: https://gis.lethbridge.ca/gisopendata/rest/services/OpenData/
• Supports where, outFields, resultRecordCount, f (json/geojson) parameters
• Max 2000 records per query

Data Sources

All data is sourced from the City of Lethbridge's Open Data Portal (opendata.lethbridge.ca). See references/datasets.md for a curated list of popular datasets.
