Summary

Antigravity CLI 1.3.6 now supports Claude Opus 5.5 and Sonnet 5.5 models, making it easier to work with the latest AI capabilities. We've also fixed critical issues where agents would hang indefinitely and improved Auto mode to be smarter about which commands it approves. Chec...

Release Notes

• Added Claude Opus 5.5 and Claude Sonnet 5.5 for Application Default Credentials (AGYADCAUTH) sign-in. Claude models now appear in /model only if your Google Cloud project can use them.
• Improved Auto mode's review of commands that would leave the terminal sandbox: the review is faster and no longer times out without a decision, it allows the workspace's own format, lint, and fix commands instead of asking about them, and it blocks commands that would upload sensitive data.
• Improved the /diff Commit Tree view with colors: commit hashes and change IDs are highlighted, descriptions are dimmed, the Working Copy (Uncommitted Changes) row stands out, and @ is bold, so hashes, timestamps, and descriptions no longer run together.
• Fixed the agent hanging indefinitely when the model connection stalled: if no data arrives for 5 minutes the request is now canceled and retried automatically, and a stalled request no longer leaves an empty response step behind.
• Fixed questions asked by subagents and workflow agents being lost, which left the subagent waiting forever: the alert now reads <agent> has a question and shows it, and Ctrl+K or a in the subagent's view opens a question picker that sends your answer to that agent. Headless -p runs skip these questions so the subagent can continue.
• Fixed agent shell commands hanging on an invisible editor when a version control command wants one, such as git commit without -m or jj describe: the CLI now sets GITEDITOR, HGEDITOR, and JJEDITOR to false for agent commands, so they fail right away instead.
• Fixed skills, rules, workflows, and Markdown agents failing to load with mapping values are not allowed in this context when an unquoted description: contains a colon, such as description: Runs checks: formatters and linters.
• Fixed Mermaid diagrams that start with YAML frontmatter, a %%{init: ...}%% directive, or %% comments, or that use Mermaid v11 syntax such as id@{ shape: ..., label: ... } nodes, showing as raw source instead of rendering in agent responses and the artifact viewer.
• Fixed the @ file-mention dropdown staying open after a newline in a multi-line prompt, where it took over Up/Down and made Enter pick a file instead of inserting the newline.
• Fixed / search in the file and artifact viewer highlighting the wrong characters, or crashing, on lines with letters whose lowercase form has a different length such as İ; n and N now stop only on lines that show a highlight.
• Fixed long lines and file paths containing CJK or other multi-byte text turning into � characters in /codesearch results; they are now cut cleanly with an ellipsis.
• Fixed agy plugin validate, the summary agy plugin install prints, and marketplace previews in the /plugin Discover tab leaving out subagents a plugin declares in its root agents.json.
• Fixed plugin names and manifests being case-sensitive where the agent was not: /plugin subcommands such as /plugin List now work in any case instead of failing with Unknown subcommand, and a manifest named Plugin.json is now found by agy plugin install, agy plugin validate, and enable and disable.
