This skill should be used when the user asks to "query Chicago data", "find Chicago datasets", "get Chicago crime data", "download Chicago permits", "write a SODA query for Chicago", "search data.cityofchicago.org", or mentions Chicago city data (311, permits, licenses, inspections, crimes, etc.).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Chicago Data Portal Skill Query and download datasets from the City of Chicago Data Portal using the Socrata Open Data API (SODA) and SoQL. ## Prerequisites Before querying, check if the user has an app token: 1. Look for `CHICAGO_DATA_PORTAL_TOKEN` in the user's `.env` file 2. If found, use it in requests via header: `X-App-Token: <token>` 3. If not found, instruct the user to: - Sign up at https://data.cityofchicago.org/signup - Create an app token in Developer Settings - Add to `.env`: `CHICAGO_DATA_PORTAL_TOKEN=your_token_here` Queries work without a token but are rate-limited. ## Quick Start The Chicago Data Portal is at `data.cityofchicago.org`. Each dataset has a unique 4x4 ID (e.g., `ijzp-q8t2` for crimes). Use the catalog API to discover datasets, then query via SODA. ## Workflow ### Step 1: Clarify the Data Need Ask the user: - **Topic**: What data? (crimes, permits, 311 requests, businesses, etc.) - **Geography**: Citywide, ward, community area, or specific location/radius? - **Time window**: Date range or "most recent"? - **Output**: JSON (code) or CSV (Excel)? - **Granularity**: Raw rows or aggregated counts? ### Step 2: Find the Dataset …

How to install
mdr add misterclean/ai-plugins/chicago-data-portal@sha256:01a75f43f2125935The line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
