adk

Companion code for Google Agent Development Kit (ADK) for Java: Your First Multi-Agent App on ankurm.com. Two LlmAgents in a SequentialAgent: a researcher that calls a tool and saves its answer to session state, and a writer whose instruction reads that state.

There is no Gemini key here. ScriptedLlm is a small BaseLlm that behaves like a tool-calling model, so the agents, the tool call, the session and the state hand-off all run for real while the model is the one scripted part.

mvn test -pl adk      # rewrites output/*.txt

File	Role
OrderTools	The tool: a public static method with @Schema parameter annotations
ScriptedLlm	The stand-in model; records every LlmRequest it receives
SupportPipeline	The two agents and the SequentialAgent that runs them
SupportPipelineTest	Three tests; each writes output/NN-*.txt. Map entries inside tool results print in a different order from run to run, so compare content, not line order
