Antigravity CLI 1.3.6

[Improvements] Added Claude Opus 5.5 and Claude Sonnet 5.5 for Application Default Credentials (AGY_ADC_AUTH) sign-in. Claude models now appear in /model only if your Google Cloud project can use them.

[Improvements] 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.

[Improvements] 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.

[Fixes] 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.

[Fixes] Fixed questions asked by subagents and workflow agents being lost, which left the subagent waiting forever: the alert now reads 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.

[Fixes] 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 GIT_EDITOR, HGEDITOR, and JJ_EDITOR to false for agent commands, so they fail right away instead.

[Fixes] 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.

[Fixes] 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.

[Fixes] 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.

[Fixes] 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.

[Fixes] 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.

[Fixes] 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.

[Fixes] 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.
