Enable agy acp as your editor's Agent Client Protocol server

Run agy acp so Antigravity 1.5 speaks ACP over stdio for editors, with image/file prompts, mid-turn steering, default/accept-edits/plan modes, session/resume without history replay, per-session model and thinking level, and agy acp --login for SSH or no-browser Google sign-in.

Why this loop

Antigravity 1.5.0 adds acp to agy --help: agy acp runs the CLI as an Agent Client Protocol server over stdio so editors can use it as their agent. That is the workflow to adopt instead of a separate chat window. Sign in from a terminal with agy acp --login when the editor is over SSH or has no browser. Prompts can include images and embedded file context. Steer a running turn by sending another prompt rather than cancelling. Pick session mode default, accept-edits, or plan. Use session/resume to restore a session without replaying its history. Each session keeps its own model and thinking level, so parallel editor sessions stay isolated.

Proposed actions

Run agy acp --login in the terminal to complete Google sign-in for editors connected over SSH or without a browser.
Point your editor's Agent Client Protocol agent command at agy acp so the editor uses Antigravity as its agent over stdio.
For each ACP session, set mode to plan, accept-edits, or default; 1.5 keeps model and thinking level on that session only.
Restore work with ACP session/resume instead of replaying history; steer an in-flight turn by sending another prompt (images and embedded file context are supported).

Verified excerpt — the source's own words

Added acp to agy --help: agy acp runs the CLI as an Agent Client Protocol (ACP) server over stdio, so editors can use it as their agent, with images and embedded file context in prompts, steering a running turn by sending another prompt, default, accept-edits, and plan session modes, session/resume restoring a session without replaying its history, each session keeping its own model and thinking level, and Google sign-in from a terminal with agy acp --login for editors connected over SSH or without a browser.
Added --remote-agent to agy --help, which runs the session's conversations on remote agents instead of this machine, where --project names a remote project by ID or name and otherwise conversations open in your default remote project; in these sessions @-mention completion now searches the remote agent's files, artifacts that can't be shown in the terminal get an Open in browser link, the header shows remote workspace instead of your local directory, the / menu no longer offers skills from this machine, and the Remote tab in /config shows the conversation's own permission preset when it has one.
