About DAWA Address Normalization & Geocoding

Equips autonomous agents with the rules of the Danish Address Web Architecture (DAWA). Teaches agents how to handle Danish characters (æ, ø, å), separate street name from house number and floor/door identifiers, perform fuzzy autocomplete, and fetch authoritative ETRS89/UTM32 and WGS84 coordinates.

# DAWA Address Normalization Skill

Use this skill when processing user-provided or extracted Danish postal addresses.

## Core Rules
1. **Danish Special Characters**: Never strip `æ`, `ø`, or `å`. If user input uses replacements (`ae`, `oe`, `aa`), use DAWA's fuzzy matching (`fuzzy=true`) rather than naive exact string matching.
2. **Structure**:
   - `vejnavn` (Street name): e.g. "Nørrebrogade"
   - `husnr` (House number): e.g. "12", "14B"
   - `etage` (Floor): e.g. "st", "1", "2"
   - `dør` (Door identifier): e.g. "th", "tv", "mf"
   - `postnr` (Postal code): strictly 4 digits (e.g. "2200")
   - `postnrnavn` (City/Town): e.g. "København N"

## Autocomplete Workflow
Call DAWA autocomplete endpoint:
`GET https://api.dataforsyningen.dk/adresser/autocomplete?q={raw_query}&fuzzy=true`

Select the matching entry and extract:
- `id`: The canonical address UUID (Adgangsadresse / Enhedsadresse).
- `adgangsadresse.koordinater`: WGS84 [longitude, latitude].
