Google Antigravity CLI 1.3.5

Changelog: Auto mode for autonomous command approvals, on-demand /compact conversation summarization, and syntax highlighting with folding in /diff

Introduces Auto mode to approve safe file edits and commands autonomously with secondary agent verification for sandbox escapes, adds the /compact slash command for on-demand context reduction, and delivers syntax highlighting, code folding, and virtualization to the /diff file viewer.

Improvements(5)

• Added Auto mode, which approves file edits and safe commands without asking and still prompts before irreversible actions; commands that would leave the terminal sandbox are first reviewed by a separate agent. Choose it with --mode auto, from Agent Mode in /config, or by pressing Shift+Tab to cycle modes. Auto mode is available on Linux and macOS, with Windows support coming later.
• Added the /compact command to compact the conversation on demand and free up the context window: /compact on its own summarizes the conversation and ends the turn, and /compact summarizes it and then answers your message. While it runs the CLI shows a Compacting conversation... progress label that you can cancel with Esc, and when it finishes it shows how many steps were summarized and how much smaller the context became.
• Added syntax highlighting to the /diff file view, with token colors for each color scheme and a background tint on added and removed lines. With the Terminal color scheme the CLI detects whether your terminal has a light or dark background and picks matching colors. The color scheme previews in /config and first-run setup now show a sample exactly as /diff draws it.
• Added folding to the /diff file view: each hunk header now shows how many unchanged lines are hidden above it, Ctrl+O expands or collapses the fold nearest the cursor, and f switches between showing only the changes and the whole file. Both keys work on uncommitted changes when the file on disk still matches the diff, and the footer explains when they can't be used.
• Improved /diff performance on very large files by rendering only the rows on screen, so scrolling, expanding folds, and opening the whole file no longer freeze the CLI. Expanding folds and showing the whole file are turned off for files over 100,000 lines or 10 MB, and the footer says why.

Fixes(1)

• Fixed colors being reduced to 256 colors in iTerm2 over SSH, where COLORTERM is not forwarded; the CLI now uses full 24-bit color when LC_TERMINAL=iTerm2 is set, unless COLORTERM or NO_COLOR says otherwise.
