Extracting Gold from Antigravity's Brain

I recently formalized a workflow to extract high-signal engineering patterns from Antigravity’s persistence layer to make them explicit and portable. By auditing the ~/.gemini/antigravity directory—specifically the walkthrough.md artifacts generated after every task, we can systematically mine for architectural decisions, edge-case solutions, and codified rules that would otherwise vanish into the ether of chat logs.

The structure of the ~/.gemini/antigravity directory is purpose-built for this kind of extraction:

~/.gemini/antigravity/
├── brain/
│   └── <uuid>/
│       ├── task.md         # The plan of record
│       └── walkthrough.md  # The forensic report
├── knowledge/
│   └── <category>/
│       ├── metadata.json   # Source provenance
│       └── artifacts/

Here is the workflow, which could be extended to extract the full knowledge base, I’m just focusing on walkthroughs for now.

Oftentimes, this workflow is triggered automatically when challenges are encountered!
