Google Antigravity joins the built-in agents.
Sub-agent transcripts and task details slide in from the right instead of opening as a dialog you have to close.
New
- Google Antigravity is a built-in agent. Install and launch it from the agent list — history, resume, skills, experts, Office tools, MCP and delegation all wired up — with a settings page for its four sign-in methods. Apple Silicon, Linux and Windows; Google publishes no Intel Mac build.
- Panels slide in beside your work instead of covering it. The mobile sidebar, aux panel, terminal, settings navigation, skill details and task details are inset drawers now, with nothing dimmed behind them.
- Session viewers stack. Sub-agent, work-task and grok child transcripts nest inside one another rather than burying each other, and no longer close when their card scrolls away or you switch tabs.
- Repository items open in a side panel. The full description, every label and the same Start action — without leaving for the forge and losing your filters, page and scroll position.
- Choose which navigation rows the sidebar shows. Automations, To-dos and the Repository panel each switch off in the view options and stay reachable from quick actions.
- A session takes its title as soon as the agent picks one, along with any forum topic bound to it. (#526, @Adam-Dalloul)
- Workspace backgrounds accept GIF, and animated ones play through the blur and the frosted panels.
- Reclaim a finished task's leftover worktree. One button in the task drawer removes the checkout and its work branch; the task stays on the board.
Improved
- Updated bundled agents. DeepSeek Harness 0.6.0, OpenCode 1.18.21, Cline 3.0.57.
- DeepSeek Harness 0.6.0 support. Image prompts keep their pictures, compaction reports tokens and elapsed time, and forking, image upload and multi-provider models turn on when the agent advertises them.
- The sidebar's view options are sorted out. Toggles move into submenus so Sort by and Section order come first, and expand/collapse-all becomes its own header button that folds the flat sections too.
- System messages show a preview. Claude Code's post-/compact summary was a shut accordion; it renders clamped now, with a toggle only when there is more to see.
Fixed
- Codex sessions created by other tools display properly. One recorded without Codex's usual event channel came back as a bare "Used 25 tools". (#452)
- pi keeps its status lines out of its answers, and routes retries to the shared banner. (#525)
- A proxy typed without http:// no longer breaks agent installs, which used to abort with an unexplained ERR_INVALID_URL; socks5:// addresses are left alone.
- Claude's model picker no longer lists null. Binding a provider with no model wrote literal nulls into ~/.claude/settings.json.
- Office lock files stop previewing themselves, each costing a tab and a watcher over a ~$ file that can never render.
- A GitLab account shows its initials when its avatar can't load, instead of an empty circle.
- The comment written back on an issue stops linking to the wrong page, and a locally merged task no longer reads as work that shipped.
- A repository row keeps its task badge. A stale lookup blanked it, so an issue already being worked on offered Start — and got a second task.
- A finished task's worktree removal isn't refused. Merge recovery left a dead connection behind that read as an agent still working in there.
- A task in review survives a cancelled session. (#546, @lizzjin)
- An agent home written as ~/… resolves to the right place. Hermes built a literal ~ directory beside its launch directory; Antigravity and DeepSeek were refused write access to the tree they actually use.
Thanks to @Adam-Dalloul and @lizzjin for contributing to this release.
