Antigravity

Audience: Any user running a local Antigravity agent. No programming experience required after the one-time system prompt setup.

Antigravity loads skill files directly from GitHub at runtime using its read_url_content tool — you always get the latest skill version automatically.

Prerequisites

Requirement	How to get it
Antigravity installed	antigravity.dev
Python 3.10+ with aggeodata	See below
Internet access	Required to fetch skill files

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

Step 0 — System prompt

Each skill page includes the system prompt to paste into Antigravity. Find it in the Antigravity tab of the skill you want to use — for example, GCF Pipeline → Antigravity.

Troubleshooting

Symptom	Fix
read_url_content returns an error	Verify Antigravity has web access enabled
ModuleNotFoundError: aggeodata	Run the pip install command above
Agent invents code	Confirm the system prompt was saved correctly
