Getting started

Skills are domain-specific instruction sets loaded into an AI agent. When you describe what you need, the agent reads the relevant skill and acts as a specialist — calling the right APIs, writing correct code, and following established workflows. You don’t need to know the tool names or parameters.

Choose your agent

Agent	Audience	Setup effort
Claude Code	Developers with a Claude Pro/Max/Team plan	Low — one terminal command
Antigravity	Any user, no subscription needed	Low — paste a system prompt
OpenAI Codex	Any user with a Codex subscription	Low — paste a system prompt

See the usage guides for step-by-step instructions per platform.

Install aggeodata

All skills are powered by the aggeodata Python package. Install it once:

pip install "aggeodata[download,mcp] @ git+https://github.com/anaguilarar/aggeodata.git" s3fs zarr

AgERA5 only: If you need hourly relative humidity, vapour pressure, or reference ET, also register for a free CDS API key at cds.climate.copernicus.eu and create ~/.cdsapirc with your credentials.

Run your first pipeline

Open Claude Code in the project root directory and type:

Download and visualize monthly solar radiation and wind speed
from NASA POWER for Bolivia from 2020 to 2022, per department.
Output to D:/tmp/bolivia_climate

Claude will show you a plan, ask for confirmation, then deliver:

File	Description
*.nc	Raw climate rasters
summary_*.csv	Monthly statistics per admin unit
*_analysis.ipynb	Jupyter notebook with Plotly charts
*_dashboard.html	Standalone HTML dashboard

How skills are loaded

In Claude Code, skills live in .agents/skills/ and are loaded automatically via CLAUDE.md.

In Antigravity and Codex, skills are fetched from GitHub at runtime. The system prompt tells the agent which URLs to read — see the usage guides for the exact prompts to paste.
