Google Antigravity v0.1.14

0.1.14 August 21, 2026 Workspace path resolution against current working directory, compaction event deduplication, and Vertex auth overrides Resolves relative workspace paths against the current working directory, prevents duplicate compaction hook dispatches and compaction index inflation, and adds support for Vertex AI gateway authentication overrides. Improvements (1) Vertex Endpoint Authentication Overrides : Enhanced VertexEndpoint to support custom authentication headers and token overrides when routing inference requests through API gateways or proxy servers. Fixes (2) Workspace Path Resolution : Fixed relative workspace paths in LocalAgentConfig(workspaces=[...]) incorrectly resolving against app_data_dir instead of the process working directory. Compaction Hook Deduplication : Fixed on_compaction hook dispatching multiple times per compaction event and resolved over-counting in compaction_indices by adding terminal state deduplication. Patches (0) 0.1.13 August 18, 2026 Pre-tool argument modification, synchronous lifecycle hooks, RunCommandConfig timeouts, and step correlation IDs The 0.1.13 release introduces pre-tool argument modification capabilities in lifecycle hooks, adds native support for synchronous hook functions, and establishes structured command execution configuration with configurable execution timeouts. It also improves tool execution observability with step correlation IDs and enhances connection resilience during client disconnects. Improvements (5) Pre-Tool Hook Argument Modification : Pre-tool lifecycle hooks can now sanitize, transform, or override tool input arguments before tool execution begins. Synchronous Hook Function Support : Lifecycle hook decorators now accept standard synchronous functions alongside asynchronous coroutines without raising runtime await errors. Structured Command Execution Configuration : Command execution settings are now consolidated under RunCommandConfig , introducing configurable timeouts that default to
