Security Scan

The skill appears to do exactly what it claims—query Montreal's public CKAN open-data portal—and it does not request credentials, unusual install steps, or access unrelated system resources.

Purpose & Capability

Name/description (Montreal open data via CKAN) matches the code and instructions: the script calls the donnees.montreal.ca CKAN API, exposes search/list/info/fetch functionality, and the SKILL.md documents those commands.

Instruction Scope

Runtime instructions only invoke the included Python CLI to query the CKAN API and print or export results. The SKILL.md does not ask the agent to read unrelated files, environment variables, or send data to third-party endpoints.

Install Mechanism

There is no install spec (instruction-only). The included script uses only Python stdlib and no external downloads or package installs, so nothing arbitrary is written to disk beyond a small cache.

Credentials

The skill requests no environment variables, no credentials, and the script does not attempt to read secrets. Network access is limited to the official donnees.montreal.ca CKAN API.

Persistence & Privilege

always is false and the skill does not modify system or other-skill configs. It writes a local cache file under the script directory (.cache/catalog_cache.json), which is reasonable for a client-side catalog cache.

Assessment

This skill is internally consistent and appears benign: it only queries the City of Montreal CKAN API and caches a local catalog file. Before installing, confirm you are comfortable allowing the agent to make outbound HTTPS requests to donnees.montreal.ca and to create a small cache file in the skill's directory. If you need extra caution, run the script in an isolated environment or review/execute the included Python file manually first.

Access and analyze 398+ open datasets from the City of Montreal via the CKAN API. Data covers crime, transit, environment, permits, employment, and more.
