Google Antigravity CLI 1.1.13

Changelog: GEMINI_API_KEY authentication, custom agent task management, embedded ripgrep caching, and conversation database fixes

Direct GEMINI_API_KEY authentication support, /codesearch fallback resilience, cached artifact list scrolling, manage_task access for custom declarative agents, embedded ripgrep caching with SHA-256 verification, and critical fixes for trajectory truncation, database growth, transcript race conditions, and subagent path validation.

Improvements(10)

• Added support for GEMINI_API_KEY, allowing the CLI to run directly against the Gemini API without signing in. Set modelProvider: "gemini" in settings.json, export GEMINI_API_KEY, and optionally configure GOOGLE_GEMINI_BASE_URL for custom endpoints. The banner and /help show Gemini API key as the credential, and /logout explains that it originates from the environment.
• Improved /codesearch resilience by falling back to a local search when the ripgrep binary cannot be executed, such as when blocked by endpoint security software.
• Improved artifact list scrolling performance by caching each file's preview line count instead of re-reading every listed file from disk on every keypress.
• Improved custom agent support by making manage_task available to declarative agents that have not opted out of fundamental components, enabling custom agents to list and kill background tasks, with clearer step descriptions like Killed task X and Checked task X.
• Improved search_web step visualization by displaying the query while the search is in progress rather than only after completion.
• Improved agent behavior after backgrounding tasks by removing anti-polling reminder text from manage_task and manage_inbox tool responses to prevent unintended polling loops.
• Improved the /resume picker by clearly relabeling its second tab.
• Improved deleting conversations in the /resume picker by remapping the shortcut from ctrl+delete to f4 for reliable cross-platform terminal compatibility on macOS.
• Improved the load time when opening large conversations by fetching step headers in batches without reading each step's full payload.
• Improved embedded ripgrep reliability and security by extracting binaries into the user cache directory instead of /tmp, adding SHA-256 integrity verification, and using atomic renaming to prevent concurrent execution races.

Fixes(11)

• Fixed distorted startup banner rendering in Cloud Shell by automatically enabling a conservative rendering mode for web terminals.
• Fixed direct Gemini API mode getting stuck on the sign-in screen instead of launching into the main UI, and resolved failures with custom GOOGLE_GEMINI_BASE_URL endpoints by omitting unsupported session fields.
• Fixed conversations disappearing from the /resume picker after switching tabs, and preserved the tab hint in the shortcut bar even when a tab is empty.
• Fixed trajectory truncation over-pruning conversation history by charging the size budget solely against reclaimable steps rather than protected checkpoints or already-cleared residues.
• Fixed unbounded growth of the SQLite conversation database during background task and subagent wakeups caused by duplicate grants and settings being appended to persisted rows.
• Fixed transcript corruption caused by background messages appending while context compaction was rewriting the log.
• Fixed an issue where a hung sandbox initialization prevented subsequent messages from being processed.
• Fixed path traversal vulnerability in define_subagent by strictly validating model-supplied agent names before creating directories.
• Fixed artifact list rendering bugs involving wide CJK characters and emoji, boundary handling when entries disappear, and viewport scrolling overflow.
• Fixed Esc key in the artifact viewer triggering duplicate review submission confirmations for previously completed reviews.
• Fixed missing tool call line rendering in collapsed/expanded tool groups for invoke_subagent, send_message, manage_subagents, define_subagent, and generate_image.
