forest-register

forest-register is a skill for Claude Code from taivop/marketplace. It costs 29 tokens per session (531 once invoked), scanned A, original, MIT.

A connector for Estonia’s public Forest Register, a government database of forest properties, land divisions, forest stands, and forestry information. It sends searches to the register’s public JSON API, which returns structured records and map geometry.

In plain words
What is it for?
Use it to find forest records by cadastral identifier, property number, property name, or forest quarter. It also helps retrieve stand details, ownership labels, inventory information, areas, species data, proposed work, and geographic boundaries.
Why use it?
It avoids manually searching the register website or interpreting pages that are difficult for software to process. It provides property and forest data in a format other tools can use.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

forest-register scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Forest Register

Access

  • Application: https://register.metsad.ee/
  • API base: https://register.metsad.ee/portaal/api/rest/
  • No authentication is required for the public calls below.

Send GET eraldis/puu with one or more URL parameters:

  • katastriNr: cadastral identifier.
  • kinnistuNr: property number.
  • yksuseNimi: property name.
  • kvartaliNr: forest quarter number.
  • maakondKood and valdKood: optional location narrowing.

At least one of katastriNr, kinnistuNr, yksuseNimi, or kvartaliNr is required; county or municipality alone is not a search. Example:

GET https://register.metsad.ee/portaal/api/rest/eraldis/puu?kinnistuNr=12345

The response is a property tree: top-level units contain alamYksused, and cadastral sub-units contain eraldised. Each stand has an id, katastriNr, eraldiseNr, pindala, status, ownership label, and EPSG:3301 GeoJSON string.

Detail

Use the stand id, not its displayed stand number:

GET https://register.metsad.ee/portaal/api/rest/eraldis/detail/{id}

Return identifiers, property and cadastral data, inventory date, county/municipality, area, site and main-species codes, dimensions, age/composition elements, volume/increment, damage, special features, proposed work, ownership fields, and alaGeoJson as available.

Limits

  • Code fields such as kasvukohaKood, peapuuliik, and tooKood are register classifications; do not guess labels when a code list has not been retrieved.
  • Dates are Unix epoch milliseconds in several fields.
  • alaGeoJson is a JSON-encoded string in EPSG:3301, not an already parsed WGS84 geometry.

Verify

Require a non-empty eraldised list, then require the detail response id to match the requested stand and preserve katastriNr plus eraldiseNr.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
