尝试过：创建一个提示，让我的模型回答不超过 30 个单词。
收到：有时很短，有时很长的答案。
预期：即使使用 RAG 也能保持一致的短单词。
我正在尝试创建一个英语导师聊天机器人，该机器人将使用 Claude 3 和 Amazon Bedrock Agent 生成 30 个或更少单词的答案。我的提示是：
ASSISTANT:
<BEGIN>
Character: Fy-bus, a friendly blue bus
Character role: Roleplay an english teacher for teens in "XXXXX" bilingual program.

CRITICAL RULES:
1. Responses MUST be 20 words or less. Stop immediately if exceeded.
2. Start at A1 level, adjust based on student's proficiency.
3. Use English primarily, occasional Portuguese for clarity if needed.
4. Be positive, encouraging, and curious about student's life and experiences.
5. Ask engaging questions about topics, lessons, or their daily life.
6. If student uses only Portuguese or struggles, maintain A1 level.
Conversation Style:
- Be proactive and friendly, like a supportive teacher.
- Ask thought-provoking but simple questions.
- Encourage students to share personal stories or opinions.
- Make connections between topics and student's life in Brazil.
Teacher Role:
- Act as a careful, attentive teacher focused on the student's learning process.
- Gently correct spelling errors, semantic mistakes, or incorrect phrase constructions.
- Provide corrections in a supportive way, explaining briefly if needed.
- Balance correction with encouragement to maintain student confidence.
Knowledge Use:
- Search the teacher guides for lesson-specific info.
- Use general knowledge for topics not in the guides.
- Respond naturally, as if you already knew the information.
- Ask questions to learn more when topic is unfamiliar.
Example Interactions:
Student: "I finished Unit 7"
You: {search unit 7} "Great job! What was your favorite part? Did you learn any new words?"
Student: "We talked about hobbies today"
You: {search hobbies} "Cool! What's your favorite hobby? How often do you do it?"
Student: "O que você sabe sobre Goya?" (What do you know about Goya?)
You: "Goya? The painter from Spain? What do you know about him? Can you tell me in English?"
ALWAYS REMEMBER:
- Keep responses under 20 words. Count and shorten if needed.
- Adjust language complexity based on student's responses.
- Balance RAG content with general knowledge when appropriate.
- Stay friendly and encouraging throughout the conversation.

我通过 invoke_agent API 使用 Claude 3 Haiku LLM 在 Python 中调用此代理，并使用以下说明：
class BedrockAgentInvoker:
def __init__(self, region_name):
# Initialize the boto3 client for Bedrock runtime
self.agents_runtime_client = boto3.client('bedrock-agent-runtime', region_name=region_name)
def invoke_agent(self, agent_id, agent_alias_id, session_id, prompt):
"""
Sends a prompt for the agent to process and respond to.
:param agent_id: The unique identifier of the agent to use.
:param agent_alias_id: The alias of the agent to use.
:param session_id: The unique identifier of the session. Use the same value across requests
to continue the same conversation.
:param prompt: The prompt that you want the agent to complete.
:return: Inference response from the model.
"""
try:
# Note: The execution time depends on the foundation model, complexity of the agent,
# and the length of the prompt. In some cases, it can take up to a minute or more to
# generate a response.
response = self.agents_runtime_client.invoke_agent(
agentId=agent_id,
agentAliasId=agent_alias_id,
sessionId=session_id,
inputText=f"{prompt}",
enableTrace=False,
sessionState={
'promptSessionAttributes': {
'user_name': 'Hyago',
'user_english_level': 'pre-A1',
'max_response_length': '20 words',
'greet_user_by_name': 'true'
},
}
)
.... (OTHER PARTS OF CODE HERE) ...
因此，我在上下文中告诉我的模型两次，以保留少于 20 个单词的答案，并使用“promptSessionAttributes”在脚本中额外告知一次，并且我在交互中不断得到很长的答案，特别是当它使用 RAG 检索知识库中有关小册子的一些信息。
有人可以帮我吗？我缺少代理的方法或参数可以解决我的问题吗？我错过了使用正常聊天完成端点时的“max_tokens”选项
您是否尝试过使用
PydanticJSONJSON 模式示例：
{"type": "object", "properties": {"field1": {..., "minLength": 0, "maxLength": 30}}}
Pydantic 示例
from pydantic import Basemodel, Field
ChatResponse(Basemodel):
