Antigravity SDK 0.1.10

[Improvements] Gemini prioritized inference service tier: Configure agents to utilize Gemini Prioritized Inference service tiers for high-priority model execution with automated graceful fallback.

[Improvements] Tool call ID correlation in lifecycle hooks: Inspect call_id attributes on tool executions, errors, and hooks to correlate multi-step tool invocations across lifecycle callbacks.

[Improvements] Context-aware hook decorators: Decorate hook handlers (@hooks.pre_turn, @hooks.post_tool_call, etc.) that optionally accept HookContext as a parameter to maintain state and share data across lifecycle callbacks.

[Improvements] ActionCompaction event emission and hook: Track context window compaction notifications over WebSockets and intercept them using @hooks.on_compaction.

[Improvements] Live token usage reporting: Introduced real-time UsageUpdate event streaming so token usage accumulates live during agent execution rather than delaying updates until state transitions.

[Improvements] Standardized system instructions strategy: Plain string instructions default to appending to built-in instructions. To override and completely replace built-in instructions, pass CustomSystemInstructions.

[Improvements] Interactive CLI spinner: Updated CLI interactive loop spinner to list all active tool names when running concurrent tool calls (for example, Running tools 'tool_a', 'tool_b').

[Improvements] Module re-exports: Re-exported ReadUrlContentResult and SearchWebResult in connections.local for uniform tool result access.

[Improvements] LiteRT token output limit: Increased max_output_tokens default in LiteRT local server configuration from 8,192 to 16,384 tokens to prevent truncation during complex reasoning and generation tasks.

[Fixes] ActionCompaction event emission: Fixed issue where compaction notifications were suppressed in external SDK releases, causing @hooks.on_compaction handlers and conversation.compaction_indices tracking to fail; compaction events now emit properly over WebSockets.

[Fixes] MCP test server startup: Fixed a race condition where the HTTP port was exposed before uvicorn server startup completed, which previously caused intermittent ConnectionRefusedError failures during test initialization.

[Improvements] Local Gemma model documentation: Added guides and tutorials for running agents locally with Gemma models using LiteRT and OpenAI-compatible endpoints.
