geotoolbox

geotoolbox is a skill for Claude Code from rshankras/claude-code-apple-skills. It costs 46 tokens per session (2,743 once invoked), scanned A, original, MIT.

A guide to GeoToolbox, an Apple framework for representing places with coordinates, addresses, names, and identifiers from different map services.

In plain words
What is it for?
It covers creating place data, converting MapKit map items, and translating between addresses and coordinates.
Why use it?
It helps developers use one consistent place format instead of writing separate handling for each map provider.

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

geotoolbox 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 5d 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.

GeoToolbox and PlaceDescriptor Patterns

Portable location representation using PlaceDescriptor from the GeoToolbox framework. Covers place construction from coordinates, addresses, and MapKit items; forward and reverse geocoding with the new async APIs; and multi-service place identifiers for cross-platform interop.

When This Skill Activates

Use this skill when the user:

  • Asks about GeoToolbox or PlaceDescriptor
  • Wants to represent a place with coordinates, address, or common name
  • Needs to convert between MKMapItem and PlaceDescriptor
  • Asks about forward geocoding (address to coordinates) or reverse geocoding (coordinates to address)
  • Wants to store or transmit multi-service place identifiers (Apple Maps, Google Maps, etc.)
  • Mentions PlaceRepresentation, SupportingPlaceRepresentation, or MKGeocodingRequest
  • Asks about portable or interoperable location data structures

Decision Tree

What do you need?
|
+-- Represent a place with coordinates and/or address
|   +-- From a known coordinate
|   |   +-- PlaceRepresentation.coordinate(CLLocationCoordinate2D)
|   +-- From a known address string
|   |   +-- PlaceRepresentation.address(String)
|   +-- Both coordinate and address
|   |   +-- Pass multiple representations to PlaceDescriptor
|   +-- From an existing MKMapItem
|       +-- PlaceDescriptor(item: MKMapItem)
|
+-- Geocode an address to coordinates
|   +-- MKGeocodingRequest(addressString:)
|   +-- try await request.mapItems
|
+-- Reverse geocode coordinates to an address
|   +-- MKReverseGeocodingRequest(location:)
|   +-- try await request.mapItems
|
+-- Attach service identifiers (Apple Maps, Google, etc.)
|   +-- SupportingPlaceRepresentation.serviceIdentifiers([String: String])
|
+-- Read place properties
    +-- descriptor.coordinate, descriptor.address, descriptor.commonName
    +-- descriptor.serviceIdentifier(for: "com.apple.maps")

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.
