Permissions

The engine runs through two tools: lagune_read only reads your project, and lagune_write only writes to .lagune/. A command sent as a session's first message runs before they load, so it uses npx instead. To allow the tools and npx up front, add these rules to ~/.gemini/antigravity-cli/settings.json:

{
  "permissions": {
    "allow": [
      "mcp(lagune_lagune/lagune_read)",
      "mcp(lagune_lagune/lagune_write)",
      "command(regex:npx --yes lagune@[0-9.]+)"
    ]
  }
}
