Fetched SKILL.md/README and ran the full skill against live Socrata. Legals (8h5j-fqxa) by borough=1&block=77&lot=1 returned 20 document_ids; the Master (bnx9-e6tj) and Parties (636b-3b5g) IN(...) joins returned 200 with real data, producing a populated deed+mortgage report (e.g. 1986 $1M mortgage, MANHATTAN SAVINGS BANK -> 85 John St Partnership). Verified the skill's field warnings: doc_date/doc_amount/combined-bbl all HTTP 400, while document_amt/recorded_datetime/separate boro-block-lot all 200 — so the baseline naive attempt fails where the skill recipe works. Two real gaps observed: Step 3d's code-translation table (7isb-wh4c) exposes doc__type/doc__type_description but returns them empty for every row, so live code translation is non-functional (skill mitigates via inline common-code list); and document_date is null for older reel records, leaving the Date column blank unless you fall back to recorded_datetime, which the body doesn't instruct.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5
- Triggers reliably 5/5
- Output vs. baseline 8/10
- Docs & honesty 4/5
What Nyc Acris does
Queries NYC ACRIS property-transaction records — deeds, mortgages, liens, assignments and ownership history — by address, BBL, or BIN, using a document_id join across the ACRIS Legals, Master, and Parties datasets on NYC Open Data (no API key). Triggers when the user asks who owns a NYC property, its sale/mortgage/lien history, or recorded deeds; not for permits or violations.
