Antigravity CLI 1.5.3 shows each subagent's model and adds PLUGIN_ROOT for hooks

Released Nov 7, each subagent's model appears next to its name in the rows above the prompt and in /agents (full model and effort in the detail view, plus a model field on status-line JSON), and plugin hook commands get PLUGIN_ROOT and PLUGIN_DATA so they can use bundled files and keep state between runs. It also retries model calls that take more than 60 seconds to start responding, and stops a sandboxed command from changing environment state later loaded by persistent terminals outside the sandbox.
