LLM-backed agent
Core agent primitive — Gemini and other LLMs via google-genai. Python calls it LlmAgent; Go uses LLMAgent.
Google ADK
Google’s Agent Development Kit. Build agents on Gemini with MCP, A2A, multi-agent orchestration, and native GCP IAM. Three language implementations share the same architecture.
