roam-code vs adk-java
roam-code: Roam is a structural intelligence engine that pre-indexes codebases into a semantic graph using SQLite, tree-sitter, and git history. It provides AI coding agents with five core verbs—understand, retrieve, context, preflight, critique—replacing dozens of grep/read calls with a single graph query. The tool is 100% local, supports 27 languages, and offers 154 commands along with 120 MCP tools.; adk-java: The Agent Development Kit (ADK) for Java is an open-source, code-first toolkit designed for building, evaluating, and deploying sophisticated AI agents. It enables developers to define agent behavior, orchestration, and tool use directly in Java code for fine-grained control and robust integration with Google Cloud services.
