Antigravity CLI 1.3.5: Auto mode auto-approves safe edits and commands, reviews sandbox escapes via a separate agent, and adds /compact

Background

Half of the friction in coding agents is permission prompts: every file edit and “probably safe” shell command stops a long run, while blanket always-allow can let commands leave the sandbox. Antigravity CLI (agy) previously documented three execution modes on the modes page: default (review diffs before writes), accept-edits (auto-approve file writes), and plan (outline before coding). File-side autopilot existed; a bounded auto-approve path for safe shell commands did not.

What 1.3.5 ships

The 1.3.5 release (89081f7, 2026-10-14T03:16:53Z) adds Auto mode: it auto-approves file edits and safe commands, still prompts before irreversible actions, and sends commands that would leave the terminal sandbox to a separate agent for review first. Turn it on with --mode auto, Agent Mode in /config, or Shift+Tab; the notes say Linux and macOS now, Windows later. The same cut adds /compact (alone: summarize and end the turn; with a follow-up: summarize then answer; Esc cancels). /diff gains syntax highlighting, hunk folding, and viewport rendering, with expand-all disabled on very large files. At fetch time the public modes page still listed only the older three modes—treat the GitHub release as source of truth.

Benchmarks

No SWE, Terminal-Bench, or token-cost numbers in this cut. Verifiable product bounds: Auto is Linux/macOS-only for now; sandbox escapes go through a separate review agent; /diff turns off expand/whole-file for files over about 100k lines or 10 MB. Do not read UX notes as model score lifts.

Try it

After upgrading to 1.3.5, run agy --mode auto, or cycle with Shift+Tab / /config. Use /compact or /compact <follow-up> to free context. Review changes with /diff. Install and auth: Install; finer tool rules: Permissions. On Windows, wait for Auto or use documented accept-edits for file-side speed only.
