# EmailAgent README ## Overview The `EmailAgent` class provides an AI-powered email composition and sending capability using LangChain with OpenAI's GPT model. It includes human-in-the-loop middleware that requires approval before emails are sent. ## Configuration ### Environment Variables | Variable | Default | Description | |----------|---------|-------------| | `OPENAI_MODEL` | `gpt-4o-mini` | OpenAI model to use | ## Usage ```typescript import { EmailAgent } from './email.agent'; import { SendEmailDto } from '../dto/send-email.dto'; const agent = new EmailAgent(); const dto: SendEmailDto = { email: '[email protected]', name: 'John Doe', subject: 'Meeting Request', // optional body: 'Initial email content', // optional instructions: 'Keep it formal' // optional }; const result = await agent.sendEmail(dto); ``` ## Human-in-the-Loop Middleware The agent uses `humanInTheLoopMiddleware` which interrupts execution on the `EmailTool` before sending emails. This allows for: - **approve** - Send the email as composed - **edit** - Modify the email before sending - **reject** - Cancel the email operation The `readEmailTool` is excluded from interruption (`false`), allowing read operations to proceed without approval. ## Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `email` | string | Yes | Recipient email address | | `name` | string | Yes | Recipient name | | `subject` | string | No | Email subject line | | `body` | string | No | Initial email body content | | `instructions` | string | No | AI instructions for composing the email | ## Return Value Returns the final message content from the agent as a string.
