Use the Command Line

Supported in ADKPython v0.1.0TypeScript v0.2.0Go v0.1.0Java v0.1.0

ADK provides an interactive terminal interface for testing your agents. This is useful for quick testing, scripted interactions, and CI/CD pipelines.

Run an agent

Use the following command to run your agent in the ADK command line interface:

=== "Python"

```shell
adk run my_agent
```

=== "TypeScript"

```shell
npx @google/adk-devtools run agent.ts
```

=== "Go"

```shell
go run agent.go
```

=== "Java"

Create an `AgentCliRunner` class (see [Java Quickstart](../get-started/java.md)) and run:

```shell
mvn compile exec:java -Dexec.mainClass="com.example.agent.AgentCliRunner"
```

This starts an interactive session where you can type queries and see agent responses directly in your terminal:

Running agent my_agent, type exit to exit.
[user]: What's the weather in New York?
[my_agent]: The weather in New York is sunny with a temperature of 25°C.
[user]: exit

Session options

The adk run command includes options for saving, resuming, and replaying sessions.

Save sessions

To save the session when you exit:

adk run --save_session path/to/my_agent

You'll be prompted to enter a session ID, and the session will be saved to path/to/my_agent/<session_id>.session.json.

You can also specify the session ID upfront:

adk run --save_session --session_id my_session path/to/my_agent

Resume sessions

To continue a previously saved session:

adk run --resume path/to/my_agent/my_session.session.json path/to/my_agent

This loads the previous session state and event history, displays it, and allows you to continue the conversation.

Replay sessions

To replay a session file without interactive input:

adk run --replay path/to/input.json path/to/my_agent

The input file should contain initial state and queries:

{
  "state": {"key": "value"},
  "queries": ["What is 2 + 2?", "What is the capital of France?"]
}
