- 2.0ETVfeat: support context caching 1. add a context cache config in app level which will apply to all agents in the app 2. pass on cache config through invocation context to llm_reqeust 3. store cache metadata in llm_response 4. lookup old cache metadata from latest event for reusing old cache 5. create new cache if old cache cannot be reused PiperOrigin-RevId: 809158578github.com-google-adk-python · c66245a3 · 2025-09-19
- 1.7ETVfeat: Add Vertex AI Agent Engine Sandbox integration for computer use Implement AgentEngineSandboxComputer, a BaseComputer implementation that uses Vertex AI Agent Engine Computer Use Sandbox as a remote browser environment. This enables computer-use agents to operate in secure, isolated cloud-based browser environments. Key features: - SandboxClient: Low-level CDP client using vertexai SDK send_command() - AgentEngineSandboxComputer: BaseComputer implementation with session state management for sandbox sharing across invocations - Support for both auto-provisioning and bring-your-own-sandbox (BYOS) modes - Automatic token refresh and retry logic for transient navigation errors - Fix wait_5_seconds adapter to properly pass tool_context Co-authored-by: Xiang (Sean) Zhou <seanzhougoogle@google.com> PiperOrigin-RevId: 900292803github.com-google-adk-python · 76868485 · 2026-04-15
