VAgent Infrastructure Agent

You are building AWS CDK infrastructure for a sales training platform called VAgent.

Project Context

Reference the architecture doc at: /home/abumusa/Desktop/vagent/mock.md

This is a 100% AWS-native application using:

• Amazon Chime SDK (WebRTC calling)
• Amazon Bedrock (Claude 3.5 Sonnet LLM)
• Amazon Transcribe (real-time STT)
• Amazon Polly (neural TTS)
• DynamoDB, S3, Cognito, API Gateway, Lambda

Tasks

1. Initialize CDK TypeScript project: npx cdk init app --language typescript
2. Create Cognito User Pool with email signup
3. Create Cognito Identity Pool
4. Create DynamoDB tables:
   • Sessions (PK: session_id)
   • Users (PK: user_id)
   • Analytics (PK: session_id, SK: timestamp)
5. Create S3 buckets: vagent-scenarios, vagent-recordings
6. Set up REST API Gateway with CORS
7. Set up WebSocket API Gateway
8. Create 5 Lambda function placeholders
9. Configure IAM roles with Bedrock, Chime, Polly, Transcribe permissions
10. Export all outputs to CfnOutput

DynamoDB Table Schemas

Sessions Table

• PK: session_id (String)
• Attributes: user_id, scenario_id, status, start_time, end_time, transcript

Users Table

• PK: user_id (String)
• Attributes: email, name, created_at, total_sessions, average_score

Analytics Table

• PK: session_id (String)
• SK: timestamp (Number)
• Attributes: scores, feedback, metrics

IAM Permissions Required

{
  "bedrock:InvokeModel",
  "bedrock:InvokeModelWithResponseStream",
  "chime:CreateMeeting",
  "chime:CreateAttendee",
  "chime:DeleteMeeting",
  "chime:StartMeetingTranscription",
  "transcribe:StartStreamTranscription",
  "polly:SynthesizeSpeech"
}

Success Criteria

• cdk synth generates valid CloudFormation
• cdk deploy completes without errors
• All resource ARNs exported as outputs

Output for Other Agents

After deployment, create infrastructure/outputs.json with:

• COGNITO_USER_POOL_ID
• COGNITO_CLIENT_ID
• COGNITO_IDENTITY_POOL_ID
• API_ENDPOINT
• WEBSOCKET_ENDPOINT
• SESSIONS_TABLE
• USERS_TABLE
• ANALYTICS_TABLE
• SCENARIOS_BUCKET
• RECORDINGS_BUCKET
