Bedrock に Invoke an inline agent なる機能ができていたので試してみたよ

## これだ！！！
https://docs.aws.amazon.com/bedrock/latest/userguide/agents-create-inline.html

## なるほどわからん
というので boto3 で試してみる。

```shell
pip install boto3 -U
```

まずは boto3 をアップデートしましょう。

すると `invoke_inline_agent` API を立たけるようになります。

そしてまずはほぼ最小構成でやってみます。

```python
import boto3
from uuid import uuid4
session_id = str(uuid4())
bar = boto3.client('bedrock-agent-runtime')

response = bar.invoke_inline_agent(
    enableTrace=True,
    endSession=False,
    foundationModel='anthropic.claude-3-haiku-20240307-v1:0',
    inputText='私を手伝ってくれますか？?',
    instruction='あなたは親切なAIアシスタントです。ユーザーのお願いに優しい口調でお答えします。慇懃無礼な態度は取りません。',
    sessionId=session_id
)
for event in response['completion']:
    print(event)
```

```

なるほど、`trace=True`にしたことでトレースログが出て、chunk に出力が入っている感じだな。
ちなみに `instruction` が 40 文字未満だとエラーが出たのでご注意ください。

Agent というからには、Actionさせてみましょう。

```python
import boto3
from uuid import uuid4
session_id = str(uuid4())
bar = boto3.client('bedrock-agent-runtime')
response = bar.invoke_inline_agent(
    actionGroups=[
        {
            'actionGroupName': 'CodeInterpreterAction',
            'parentActionGroupSignature': 'AMAZON.CodeInterpreter'
        }
    ],
    
    enableTrace=True,
    endSession=False,
    foundationModel='anthropic.claude-3-haiku-20240307-v1:0',
    inputText='12345 * 456789の計算結果を計算機を使って教えて下さい。',
    instruction='あなたは親切なAIアシスタントです。ユーザーのお願いに優しい口調でお答えします。慇懃無礼な態度は取りません。',
    sessionId=session_id
)
for event in response['completion']:
    if 'trace' in event:
        print(event['trace']['trace'])
    if 'chunk' in event:
        print(event['chunk']['bytes'].decode('utf-8'), end='')
```

https://docs.aws.amazon.com/bedrock/latest/userguide/inline-agent-invoke.html
にある通りに実装したところエラーが出たので、
`name` を `actionGroupName` に変更しているところにご注意ください。

ちゃんと `codeInterpreter` を使って計算してくれました！

今回は簡易に code interpreter を使いましたが Action Group では Lambda、function の指定、Knowledge Base を使えるので、ぜひ試してみましょう。

## 終わりに
アクションや、KnowledgeBase を取捨選択したいときに使うためのツールのような印象を受けました。
すでに作った ActionGroup や KnowledgeBase を切った貼ったして使うときに便利そうですねがコピペ元の管理人がちょっとつらいシーンももしかしたらあるかもしれません。

あとはセッション管理機能とかも提供しているので、そこれへんもうまく使いたいですね。

以上、とりあえずやってみたでした。
