NYC Property Report

What it does

Provide an address, BBL, or BIN and get a comprehensive property report. The skill runs all 6 NYC property data lookups in sequence — landmarks, DOB permits, DOB violations, ACRIS records, HPD data, and BSA variances — then writes a structured markdown file with key findings summarized at the end. If any domain query fails, it notes the error and continues with the remaining domains.
