What it does
Geotoolbox is an agent skill from gustavscirulis/snapgrid. GeoToolbox PlaceDescriptor patterns with MapKit integration for location representation, geocoding, and multi-service place identifiers. Use when working with place descriptors, geocoding, or cross-service location data.
Its SKILL.md is about 3.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Data & Analytics, covering Geospatial analysis. It works with iOS and macOS. The repository describes itself as: SnapGrid is an open-source Mac app for collecting, organizing, and analyzing UI screenshots. It uses AI to automatically detect UI components and patterns, making it a powerful…
When your agent uses it
- Working with place descriptors
- Cross-service location data
Example prompts
- “/geotoolbox”
Requirements
- Pre-approved tools (allowed-tools): Read, Glob, Grep
What it can do on your machine
Read from SKILL.md and the folder at commit eb7eaf4. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGlobGrep
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are swift).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
developer.apple.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Geotoolbox loads about 3.1k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 538 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 538 words (~3,096 tokens).
“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.”
