Agy Chat for Gemini

A minimalist, ergonomic chat interface for Google Gemini in VS Code. It talks to Gemini through the Antigravity CLI (agy acp, the Agent Client Protocol), in the sidebar or in editor tabs.

Getting started

Install the Antigravity CLI (agy) and sign in with your Google account. The extension starts agy acp for you; it ships no Google software of its own.
Uninstall formulahendry.acp-client if you have it: it registers the same acp.* commands, so the two cannot be installed together.
Click the blue star (New Gemini Chat) in the editor title bar, or open the Agy Chat view in the activity bar (Cmd+Shift+A / Ctrl+Shift+A).
Type a message and press Enter.

Features

Editor-tab chats. Each tab is its own conversation; open several side by side. A tab is named after its conversation.
Attach context. + attaches files from your computer or from the workspace; paste or drop images straight into the input, and click a sent image to see it full size.
Queue messages. Type while Gemini works; queued messages wait in a card where you can send one now, edit it or delete it.
Modes. Manual, Edit automatically, Plan and Auto, from the mode menu or with Shift+Tab. Every action outside the mode asks for permission first.
Models. Pick the model per chat; acp.modelFilter hides the ones you never use.
Slash commands. / lists the agent's commands and the skills of your installed plugins.
Readable answers. Live markdown, collapsible tool steps, edit cards with the changed lines, and clickable file paths.
Context meter. A ring shows how full the context window is; click it to compact the conversation.
History. Search past chats, reopen them with their messages, or forget them.
Copy turn. Copies the prompt, the answer and its edits as plain text, ready to paste elsewhere for a second opinion.
Recovers by itself. If agy stops, the chat reconnects up to 3 times, then offers a Reconnect button.

`acp.autoApprovePermissions`	`ask`	`allowAll` approves every request without asking (see below). User settings only.
`acp.defaultWorkingDirectory`	empty	Folder the agent works in; empty uses the open workspace folder.
`acp.modelFilter`	`[]`	Show only models whose name contains one of these words, e.g. `["gemini"]`.
`acp.pluginsDir`	empty	Folder of the agent's plugins for the `/` list; empty means `~/.gemini/config/plugins`.
`acp.logTraffic`	`true`	Log the protocol traffic to the ACP Traffic output channel, on your machine only.

Bypass permissions

The mode menu has Bypass permissions. It approves every request of the agent without asking, including commands that change or delete files, in all chats. It is off by default and asks for confirmation when you turn it on. Leave it off unless you trust the work you give the agent.

Privacy

The extension collects no telemetry and no personal data.
Its only network use of its own is ACP: Browse Registry, which reads a public agent list.
Your prompts, files you attach and the agent's work go to Google through your local agy and its sign-in, under Google's terms of service and privacy policy.
