`Antigravity 2.0` Install/Update Bug Workaround: Roll Back to `1.23.2`

Rollback first, then disable background updates. Until the installer stabilizes, manual updates are the practical path.

[ KEY POINTS ]

Download 1.23.2 from previous releases instead of installing 2.0; this is a rollback workaround, not a permanent fix.
After opening Antigravity, go to Editor Settings > Application > Update and disable Windows Background Updates.
Switch update mode to Manual Mode and restart. This avoids being pushed back into the broken update path.

`Antigravity` agent sessions hit template mismatch blocker

AntigravityAI coding agent IDE — built around Google's stack
Prompt generation fails before a new agent session starts. Treat it as a blocker, not a workflow tweak.
- The failure happens in PlannerGenerator / CascadeManager, before the agent session reaches useful work.
- communication_style calls CascadeConfig.GetSupportsLatexRendering, but the current protobuf type lacks that field.
- Impact is complete session creation failure. If your workflow depends on Antigravity, keep a fallback agent ready.

AntigravityAI coding IDE — Google's agent-based dev environment
A forced IDE update allegedly scattered projects, split threads, and wiped settings. Treat agent IDEs as volatile infra: pin versions and keep rollback paths ready.
- Ultra costs $200/month, yet the reported update shipped with no email, warning, migration path, or visible rollback.
- Breakage hit core state: projects, conversations, settings, and config. Back up .vscode-style config and agent history separately.
- Users are reportedly reverting to 1.23.2 and disabling auto-update. Version pinning becomes part of production workflow.

`Antigravity CLI` lacks sandbox and custom Docker image support

Antigravity CLICoding agent CLI — command-line tool for Google Antigravity
A concrete parity gap versus Gemini CLI: no custom image or sandbox flow. Fine for light tasks, weak for reproducible agent runs.
- Gemini CLI supports custom Docker images and sandboxed execution; Antigravity CLI currently lacks that workflow control.
- The report is only 1 post with no maintainer answer, so treat it as a compatibility warning, not a roadmap signal.
- Agent runs that touch installs, DB clients, or native deps need pinned containers. Without that, CI-like reproducibility gets messy fast.
