Google Antigravity CLI 1.2.9

Changelog: Direct subagent messaging syntax, Vim numeric count multipliers, headless lifecycle handling, and concurrency fixes

Introduces direct @ prompt syntax with interactive autocomplete, adds Vim count multipliers across Normal and Visual modes, enhances headless execution lifecycle and task timeout handling, and fixes file-lock concurrency issues in conversation history databases along with streaming response stability fixes.

Improvements(6)

• Added @ prompt syntax to send a message directly to a subagent conversation, with autocomplete listing running and completed subagents.
• Added Vim numeric count multipliers so counts apply to operators, motions, and actions in Normal and Visual modes, including 3dw, 2d3w, 3dd, 3x, 3rX, 3p, 3u, [count]G/gg/$, and counted text objects such as 2di(.
• Improved GEMINI_API_KEY sessions to reduce behavior discrepancies with the non-API-key sign-in path.
• Improved the artifact viewer to show a Left/Right pan hint in the footer when a wide diagram overflows the window.
• Improved /rewind to show a relative timestamp for each step and to focus the most recent step when the panel opens.
• Improved command allow-listing suggestions to recognize jj config and jj op subcommands when offering to always allow a command.

Fixes(9)

• Fixed headless (-p / --prompt) runs leaving daemon background processes running after exit, which could hang scripts reading the CLI's output until end-of-file; daemon processes now terminate when the run ends.
• Fixed headless (-p / --prompt) runs cancelling still-running background tasks about 5 seconds after the agent went idle; runs now wait for background tasks until the --print-timeout deadline, up to a 30-minute cap.
• Fixed a conversation-history database corruption risk where checking the database file for write access could silently drop file locks held by concurrent CLI processes on the same file.
• Fixed context compaction failing when the tool configuration used for compaction checkpoints was rejected in certain scenarios.
• Fixed a backend crash when a streamed model response chunk arrived without its response envelope, which terminated the session with connection errors.
• Fixed markdown table column alignment when a table cell contains file links that wrap across lines.
• Fixed markdown file links to code symbols dropping their display text and rendering the raw path instead.
• Fixed incomplete enterprise sign-ins (for example closing the browser window before finishing license or project selection) leaving behind a stuck partial credential; such credentials are now cleared automatically so sign-in can be retried cleanly.
• Fixed the browser companion page title to read Antigravity CLI instead of Antigravity Cli.
