There was a problem hiding this comment. Thanks for the suggestion, but the paths are intentionally different and serve different purposes:
This is consistent with other IDE-based agents like Windsurf:
The AGENTS.md table documents where command files are stored, while the update-agent-context scripts manage per-project agent rules/instructions files. These are two distinct concepts with different file locations. |

In the CLI Tool column, Antigravity is listed as "antigravity", but based on the AGENT_CONFIG in init.py where
"requires_cli": False, and the Description column calling it "Google's Antigravity IDE", it should be "N/A (IDE-based)" to match the pattern of other IDE-based agents like Windsurf, GitHub Copilot, and IBM Bob.
