Evo Geospatial Antimeridian Plates

Q: Why use Evo Geospatial Antimeridian Plates on TypingMind?

Because you install it once and use it with any model. Evo Geospatial Antimeridian Plates is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

Q: How do I install Evo Geospatial Antimeridian Plates in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/OpenLAIR/OpenSkill/tree/main/tasks-evolved/earthquake-plate-calculation/environment/skills/evo-geospatial-antimeridian-plates. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Q: Which AI models can use Evo Geospatial Antimeridian Plates?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

Q: How many AI models can I use with Evo Geospatial Antimeridian Plates?

As many as you like. As long as a model supports skills, you can use Evo Geospatial Antimeridian Plates with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Q: Is the Evo Geospatial Antimeridian Plates AI skill free?

Yes. It is published on GitHub by OpenLAIR under the Apache-2.0 license. You only pay your own AI provider for the tokens you use.

Q: What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

Q: How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.

Installation

Install the Evo Geospatial Antimeridian Plates AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/OpenLAIR/OpenSkill/tree/main/tasks-evolved/earthquake-plate-calculation/environment/skills/evo-geospatial-antimeridian-plates
Enable the skill in any chat where you want it available.

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/OpenLAIR/OpenSkill.git /tmp/OpenSkill
mkdir -p .claude/skills
cp -r /tmp/OpenSkill/tasks-evolved/earthquake-plate-calculation/environment/skills/evo-geospatial-antimeridian-plates .claude/skills/evo-geospatial-antimeridian-plates

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Evo Geospatial Antimeridian Plates in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Evo Geospatial Antimeridian Plates on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Evo Geospatial Antimeridian Plates is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

evo-geospatial-antimeridian-plates

Handles loading PB2002 tectonic plate polygon and boundary GeoJSON files, filtering by plate code, and normalizing coordinates across the antimeridian to 0-360 range.

Key Concepts

Antimeridian Problem

The Pacific plate spans the 180°/-180° antimeridian. Standard WGS84 coordinates wrap at this boundary, causing catastrophic topological artifacts when projecting. Solution: shift all negative longitudes by +360 to create a continuous 0°-360° space.

PB2002 Data Model

Plates file (PB2002_plates.json): Contains Polygon/MultiPolygon geometries. Pacific plate identified by Code == 'PA'.
Boundaries file (PB2002_boundaries.json): Contains LineString geometries. Each segment has PlateA and PlateB properties. Pacific boundaries are where PlateA == 'PA' OR PlateB == 'PA'.

Coordinate Handling

Use shapely.transform(geometry, func) (Shapely 2.0 array interface) - NOT shapely.ops.transform
Use unary_union() - NOT deprecated cascaded_union
After shifting, use set_crs(epsg=4326, allow_override=True) to assign CRS metadata
Use to_crs(epsg=3832) for Pacific-centric metric projection (PDC Mercator, central meridian 150°E)

Functions

`shift_antimeridian_coords(coords)`

Shapely 2.0 transform callback. Takes (N,2) or (N,3) ndarray, shifts longitude < 0 by +360.

`load_plate_polygon(plates_geojson_path, target_plate_code='PA')`

Loads PB2002 plates, filters by code, shifts to 0-360, returns GeoDataFrame with CRS=EPSG:4326.

`load_plate_boundaries(boundaries_geojson_path, target_plate_code='PA')`

Loads PB2002 boundaries, filters by PlateA/PlateB, shifts to 0-360, returns unified MultiLineString geometry.

Usage

python
import sys
sys.path.insert(0, '/app/environment/skills/evo-geospatial-antimeridian-plates/scripts')
from utils import shift_antimeridian_coords, load_plate_polygon, load_plate_boundaries

# Load Pacific plate polygon (shifted to 0-360)
pacific_plate_gdf = load_plate_polygon('/root/PB2002_plates.json', 'PA')

# Load Pacific plate boundary as unified geometry (shifted to 0-360)
pacific_boundary = load_plate_boundaries('/root/PB2002_boundaries.json', 'PA')

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.
