Google Antigravity IDE Extensions 1.6.0

Changelog: Terminal context integration (@terminal), native notifications, auto-accept inline diffs on chat send, and faster startup

Introduces @terminal context integration to reference active terminals and command output in chat, adds in-editor and native Linux desktop notifications when the agent finishes or needs input, enables auto-accepting pending background inline diffs on chat send, and delivers faster extension startup, resilient binary downloads, and comprehensive inline diff lifecycle fixes.

Improvements(15)

• Added @terminal context integration in chat to capture and reference open VS Code terminals, recent shell commands, exit codes, and up to 8 KiB of output per terminal directly in your prompts.
• Added Antigravity: Add Terminal Selection or Output to Chat (antigravity.insertTerminalSnippet, Cmd+L on macOS) to the terminal right-click context menu, with automatic clipboard fallback.
• Added native VS Code information notifications with Open Chat and Dismiss actions when an agent task completes or needs input while the Antigravity chat panel is unfocused, automatically suppressing duplicate notifications when chat already has focus.
• Added native Linux desktop notifications (notify-send) with the VS Code desktop entry and Antigravity icon when the VS Code window is unfocused.
• Added the antigravity.autoAcceptOnChat setting (enabled by default) to automatically accept pending inline diffs in background files when sending a new chat message, while keeping the active file's inline diff open for review.
• Added an in-panel error recovery screen when the background server fails to start or crashes mid-session, with Try again to reconnect and automatic recovery polling.
• Added one-click Report issue diagnostic submission from the error screen that packages host and installation logs (diagnostics.json.gz) and submits feedback even when the backend CLI is offline.
• Improved extension startup latency by caching binary version checks using file metadata instead of computing a full-file SHA-256 hash on every launch.
• Improved initial backend binary downloads by replacing the fixed 120-second deadline with a 30-second rolling inactivity timer and automatic HTTP Range resume across retries.
• Improved backend download progress reporting with monotonic 10% step updates capped cleanly at 100%.
• Improved activation cleanup to automatically remove abandoned temporary staging files and unpack directories older than 24 hours.
• Improved backend installation retries to re-fetch the latest release manifest before retrying so mid-download release updates do not fail checksum verification.
• Increased the default backend startup timeout (antigravity.serverStartupTimeoutMs) to 30 seconds and improved startup diagnostics to distinguish early process exits and signal kills from timeouts.
• Improved the loading screen progress bar with hardware-accelerated animations and synchronized transitions into the chat view.
• Updated the Antigravity activity bar icon to a crisp monochrome vector asset and refreshed the extension marketplace icon so it renders without clipping.

Fixes(12)

• Fixed manual save (Cmd+S / Ctrl+S) and tab close (Don't Save) behavior in files with active inline diffs to prevent saving raw diff markers or leaving unintended edits on disk.
• Fixed inline diff application so unsaved manual edits made before or on top of agent changes are preserved.
• Fixed closing a tab with active inline diffs so selecting Save accepts the changes, Don't Save rejects them, and Cancel keeps the tab and diff review open.
• Fixed inline diff review zones disappearing across consecutive multi-turn agent edits.
• Fixed the editor tab dirty indicator (●) remaining visible and triggering save-conflict dialogs after accepting or rejecting inline diffs.
• Fixed inline diff disposal and files.autoSave: onFocusChange handling when switching between editor tab groups.
• Fixed reviewing earlier conversation turns so the diff view accurately shows cumulative file changes.
• Fixed diff view behavior when opening resolved versus unresolved files from the Files Changed sidebar.
• Fixed repeated "Choose a repository" prompts appearing after every inline diff edit in multi-repository workspaces.
• Fixed reopening an older conversation unexpectedly re-applying its file edits to the workspace.
• Fixed artifact review webviews clearing their own Proceed button when mounting.
• Fixed backend server readiness checks failing behind localhost proxy settings, validated the working directory before spawning when a workspace folder is deleted, and added automatic rollback if binary promotion fails on Windows.
