Issue 1: Past conversations not showing

The past conversation list in the sidebar is completely empty. No conversations are displayed, even though conversation data exists on disk under ~/.gemini/antigravity/conversations/ (verified — .pb files are present and the assistant can reference previous conversations).

Issue 2: Slash commands (/) not appearing after clean reinstall

After a complete clean reinstall, the / slash command menu no longer shows any commands. The workspace has a valid .agent/workflows/ directory with 17 workflow .md files, all with proper YAML frontmatter and descriptions. The assistant can read and execute them internally, but they don’t appear in the UI autocomplete when typing /.

Reproduction steps

  1. Complete uninstall of Antigravity

  2. Deleted the following directories:

    • ~/.gemini/

    • ~/.antigravity/

    • AppData/Roaming/Antigravity/

  3. Reinstalled Antigravity from scratch

  4. Reopened the workspace

  5. Restarted the application multiple times

After reinstall, ~/.gemini/antigravity/ was recreated with the expected structure (conversations/, brain/, knowledge/, etc.), and the assistant itself works fine. But the UI does not show:

  • Past conversations in the sidebar

  • Slash command suggestions when typing /

Expected behavior

  • Past conversations should be listed in the sidebar

  • Typing / should show autocomplete with available workflow commands

Has anyone else experienced this? Any known workarounds?
