# adk

Companion code for *Google Agent Development Kit (ADK) for Java: Your First Multi-Agent App* on
[ankurm.com](https://ankurm.com). Two `LlmAgent`s 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.

```bash
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 |
