Antigravity CLI v1.1.28

Antigravity CLI v1.1.28 was released on September 9, 2026.

Summary

Antigravity CLI 1.1.28 makes your workflows more reliable by recovering gracefully from brief service interruptions, and speeds up both sign-in and headless runs with smarter caching and reduced overhead. You'll also see clearer approval prompts and better error messages that ...

Release Notes

• Improved resilience to transient model API errors: the agent now retries errors such as 503 Unavailable for much longer with exponential backoff, so a brief service hiccup no longer aborts your session.
• Improved sign-in and startup speed by reading your signed-in identity from the stored credential instead of making a network request on every launch and after browser consent; a failed identity lookup no longer prevents sign-in from completing, and the displayed plan tier no longer briefly disappears during startup.
• Improved headless (-p) runs to exit promptly once the final answer is delivered: the CLI waits for running background tasks and scheduled timers to finish, bound by --print-timeout, and leaves daemon background tasks such as dev servers running instead of terminating them.
• Improved failure reporting in headless (-p) runs: fatal errors now appear on stderr with a stable error: marker, a note is printed when the response may be truncated, and runs that previously ended silently with no output now explain why.
• Improved headless (-p) turnaround by cutting up to 200 ms of idle latency per turn and skipping the model call that generated a conversation title no one would see.
• Improved tool approval prompts to say exactly what you are approving — for example Run this command?, Allow access to this URL?, or Allow calling this tool? — with the command-editing shortcut offered only when a command is being approved, and a Reason: line explaining why approval is being requested when it is not obvious, such as a hook flagging the action or a file belonging to a different project.
• Improved model selection auditability: the CLI log now records whenever a model name you specify resolves to a different model, such as alias resolution, --effort variant selection, or replacement of a deprecated saved model.
• Changed what happens when --print-timeout expires mid-turn: the CLI now returns the partial output it has and exits successfully with a warning on stderr, instead of failing with a timeout error; interrupts such as Ctrl+C still exit non-zero.
• Changed the default permission for fetching URLs from always allowed to asking first, so the agent now requests approval before reading a URL unless you have granted access.
• Fixed plugin reinstalls keeping files that had been deleted from the source: installing a plugin now replaces its managed directory exactly, installing a plugin from its own installed directory is refused instead of corrupting it, and uninstalling a plugin no longer leaves its enabled/disabled entry behind in config.json.
• Fixed MCP servers defined by plugins resolving relative or unset working directories against the wrong location; they now resolve against the plugin's own directory so plugin-bundled scripts run correctly.
• Fixed a startup race where subagents could fail to find tools from MCP servers that were still initializing.
• Fixed subagents sometimes appearing stuck in a running state after they had finished — especially in very large conversations — which also left queued when-idle messages undelivered until restart.
• Fixed a memory leak where every finished terminal command kept internal state alive for the rest of the session; long sessions that run many commands now use significantly less memory.
• Fixed headless (-p) runs stalling forever on implementation-plan approval that no one could give; non-interactive runs now proceed through plan review automatically.
• Fixed sign-in failing with a project access error after switching from a business account with a selected project to a personal account; stale business project and license details are now fully cleared on personal sign-in.
