# AGENTS.md - NOAA Habitat Areas of Particular Concern

Guidance for AI agents and LLMs working with this collection.

## Overview

Habitat Areas of Particular Concern (HAPCs): subsets of Essential Fish Habitat that are vulnerable or ecologically important, designated by the regional Fishery Management Councils and NOAA Fisheries (237 polygons; `HAPC_Siten` site name, `Species`, `FisheryMan` plan). The id is the source FID. The companion EFH layer is not staged: its item carries no licence text.

## Find a place

```sql
SELECT * FROM read_parquet('https://storage.oceanmetrics.io/gazetteer/noaa_hapc/places.parquet')
WHERE name ILIKE '%california%';
```

`place_id` is unique and prefixed; `status` / `status_source` / `status_date` say whether the place is current and
where that is documented. Check `status` before treating a lease or area as live.
