When switching between multiple project directories, finding past discussions in your conversation history is now much more organized.
When using the /resume command to pick a past conversation, you can now opt into a workspace-grouped view. Simply press Ctrl+F to toggle between the flat conversation list and conversations grouped by directory, quickly locating history for a specific project.
Developers who prefer connecting directly with an official API key now have a fresh, responsive option in their model list.
Once you configure GEMINI_API_KEY in your environment, the latest Gemini 3.8 Flash model appears in the model catalog. When performing routine code lookups or quick edits, you can select this model directly from the menu to enjoy greater flexibility.
When defining custom agents with Markdown files, they now receive the exact same resource configuration as default agents. Previously, custom agents did not automatically inherit ambient skills, rules, and subagents (specialized auxiliary agents that handle specific tasks), often leaving them without essential capabilities. Now, custom agents inherit all surrounding skills, rules, and subagents by default, ready to use ambient resources out of the box.
When referencing nearby modules in a custom agent's Markdown definition file, relative paths will no longer get lost depending on where you run the tool. Previously, when specifying subagents and plugins using relative paths in an agent definition, paths were often resolved against the current working directory instead of the definition file's location, causing files to go missing. Relative paths now resolve correctly against the directory containing that agent definition file.
When connecting accounts via external authorization servers, lengthy tokens no longer block your sign-in flow. During MCP (Model Context Protocol) OAuth authentication, if an authorization server returned an authorization code longer than 1024 characters, the process previously failed due to a length limitation. This limit has now been fixed, allowing authorization codes exceeding 1024 characters to authenticate successfully and complete the connection.
When viewing installed skills on Windows, categories and groupings in the panel are now much more accurate. Previously, when opening the /skills panel on Windows, host path separators (the backslash \) caused global and workspace skills to be misclassified due to path-matching issues. The path-matching and grouping logic has now been corrected so that all skills are properly sorted into their respective groups based on their actual paths.
When running multi-agent workflows or reloading sessions over extended periods, several underlying runtime and configuration issues have now been resolved. Previously, reloading sessions or invoking subagents caused duplicate permission grants to accumulate in settings files, which has now been eliminated. For accelerated execution, worker tool configurations have been improved to prevent /boost from failing at runtime. Additionally, a fatal nil pointer crash caused by background summary updates attempting to read cached steps after trajectory closure has been fixed.
When connecting from external devices to control your development environment, network transmission channels are now significantly more resilient.
Antigravity's Remote Control feature relies on reverse-tunnel routing to forward communication. This update hardens the reverse-tunnel routing mechanism, substantially improving connection stability and routing security during remote sessions.
Added an opt-in workspace-grouped view to the `/resume` conversation picker, allowing users to toggle between a flat list and conversations grouped by directory with `Ctrl+F`.Added Gemini 3.8 Flash to the model catalog when connecting with a `GEMINI_API_KEY`.Changed custom agents defined in Markdown to inherit ambient skills, rules, and subagents by default, matching the configuration of default agents.Fixed relative path resolution in Markdown-defined custom agents so relative subagent and plugin paths resolve correctly against the agent definition's directory.Fixed MCP OAuth authentication failing when authorization servers return authorization codes longer than 1024 characters.Fixed skill path matching and grouping in the `/skills` panel on Windows where host path separators (`\`) caused global and workspace skills to be misclassified.Fixed duplicate permission grants accumulating in configuration settings across session reloads and subagent invocations.
Fixed /boost failing at runtime by improving worker tool configurations.
Fixed a fatal nil pointer crash in the agent runtime caused by background summary updates attempting to read cached steps after trajectory closure.Hardened Remote Control reverse-tunnel routing.
