Catasto — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the catasto-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:

   npx -y @mvanhorn/printing-press-library install catasto --cli-only

2. Verify: catasto-pp-cli --version
3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.4 or newer). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead:

go install github.com/mvanhorn/printing-press-library/library/other/catasto/cmd/catasto-pp-cli@latest

If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.

Bridges Italian cadastral references (provincia / comune / foglio / particella) and WGS84 coordinates using the Agenzia delle Entrate public ajax endpoint plus the community-maintained ondata Parquet centroids. Produces JSON shapes that map cleanly onto downstream GIS pipelines. No credentials, no Python, no DuckDB — a single Go binary.

When to Use This CLI

Reach for this CLI whenever an agent needs to bridge Italian cadastral identifiers and geographic coordinates — real-estate due diligence, surveying preparation, GIS data enrichment, batch reverse-geocoding of address lists. It's the right tool when the work is offline-friendly, scriptable, or needs to be embedded in field laptops without Python/QGIS/DuckDB dependencies.

When Not to Use This CLI

Do not activate this CLI for requests that require creating, updating, deleting, publishing, commenting, upvoting, inviting, ordering, sending messages, booking, purchasing, or changing remote state. This printed CLI exposes read-only commands for inspection, export, sync, and analysis.

Unique Capabilities

These capabilities aren't available in any other tool for this API.

Agent-native composability

• gps — Resolve a WGS84 lon/lat point to its Italian cadastral parcel (province, comune, foglio, particella). Supports single-point and streaming batch mode.

  Reach for this when an agent has a coordinate (or list of coordinates) and needs to attach Italian cadastral references to it.

  catasto-pp-cli gps 12.4924 41.8902 --json

Local state that compounds

• cadastral — Reverse lookup: given a comune codice belfiore + foglio + particella, return the WGS84 centroid coordinates. Powered by the ondata/dati_catastali Parquet dataset, cached locally on first use.

  The headline reverse-direction lookup; pair it with gps for full round-trip between paper cadastral titles and digital maps.

  catasto-pp-cli cadastral --comune H501 --foglio 508 --particella B --json

Field-work ergonomics

• validate — Parse-only validator for cadastral references. Explains shape rules without hitting any API.

  Form-style flows and batch imports can short-circuit invalid input before burning an API call; agents use it as a guardrail.

  catasto-pp-cli validate --comune H501 --foglio 508 --particella B --json

Command Reference

lookup — Forward lookup: GPS coordinates to cadastral reference via the Agenzia delle Entrate public ajax endpoint.

• catasto-pp-cli lookup — Resolve a WGS84 longitude/latitude point to the cadastral parcel it falls inside. Returns province code, comune...

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

catasto-pp-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query.

Recipes

Resolve a coordinate to a cadastral parcel

catasto-pp-cli gps 12.4924 41.8902 --json --select SIGLA_PROV,COD_COMUNE,FOGLIO,NUM_PART

Forward lookup for a single point with narrowed JSON output for agent consumption.

Batch reverse-geocode coordinates from stdin

catasto-pp-cli gps --stdin --json

Stream lon,lat pairs (one per line, CSV-compatible) and emit one JSON object per row with the input echoed alongside the result. Points outside Italy are flagged inline rather than aborting the stream.

Reverse-lookup a cadastral reference

<!-- PATCH: Make the Comune/Foglio/Particella -> GPS workflow explicit for agents. -->

catasto-pp-cli cadastral --comune M011 --foglio 2 --particella 2 --agent

Geolocalizza una particella catastale da Comune + Foglio + Particella, restituendo coordinate GPS WGS84 (lon, lat) del centroide. --comune accetta sia codice Belfiore sia nome umano; quando usi il nome, aggiungi --provincia se il comune e' ambiguo:

catasto-pp-cli cadastral --comune "Roma" --provincia RM --foglio 508 --particella B --agent

Resolves codice belfiore/name + foglio + particella to a WGS84 centroid via the ondata Parquet dataset. First call in a region downloads and caches the file.

Validate references before importing a spreadsheet

catasto-pp-cli validate --comune H501 --foglio 508 --particella B --json

Free, deterministic syntax check. Exits 2 on invalid input with a JSON report of every problem.

Auth Setup

No authentication required.

Run catasto-pp-cli doctor to verify setup.
