Getting "BeforeTool" hook working

Hi! I have installed Antigravity 2.0 (Ubuntu). I have asked Gemini 3.5 FLASH if it supported “hooks” and it responded in the positive (after some querying of the Google Knowledge Base through MCP). I asked a simple tool: log all tool usage to a dated file. It obliged: I restarted the AG, no result. I asked to find the problem: AG did… but still it is not working. Yes I have given AG full trust.

Anybody else struggling with “hooks” in AG 2.0 ?
