Arguments: $ARGUMENTS

Goal: Implement complete email sending functionality with template support, batch processing, attachments, and scheduling capabilities

Core Principles:

• Support single and batch email sending
• Provide flexible template system
• Handle attachments securely
• Include scheduling capabilities
• Robust error handling and logging

Phase 1: Discovery Goal: Gather context and requirements

Actions:

• Parse $ARGUMENTS for flags (--batch, --scheduled)
• Load existing Resend plugin structure to understand current implementation
• Example: !{bash find /home/gotime2022/.claude/plugins/marketplaces/ai-dev-marketplace/plugins/resend -type f -name ".md" -o -name ".ts" -o -name "*.js" | head -20}
• Check if services directory exists
• Load any existing email utilities or configurations

Phase 2: Analysis Goal: Understand existing patterns and integration points

Actions:

• Read plugin README to understand scope
• Check existing agents and skills for patterns
• Identify where email service should integrate
• Determine TypeScript/JavaScript target
• Example: !{bash ls -la /home/gotime2022/.claude/plugins/marketplaces/ai-dev-marketplace/plugins/resend/}

Phase 3: Planning Goal: Design the email sending implementation

Actions:

• Outline structure needed:
  • Email service with send(), sendBatch(), sendScheduled() methods
  • Template engine with variable substitution
  • Attachment handler with validation
  • Error handling and retry logic
  • Scheduling system integration
• Identify configuration requirements
• Plan integration with existing plugin structure

Phase 4: Implementation Goal: Generate email functionality with agent

Actions:

Task(description="Create email sending service", subagent_type="resend-email-agent", prompt="You are the resend-email-agent. Create comprehensive email sending functionality for the Resend plugin.

Requirements:

• Create email.service.ts with:

  • send(to, from, subject, html, text?) method for single emails
  • sendBatch(emails[]) for batch operations with concurrency control
  • sendScheduled(email, scheduledFor) for scheduled sending
  • Proper Resend API integration with error handling

• Create templates.ts with:

  • Template interface: {id, subject, html, variables}
  • renderTemplate(template, variables) function
  • template registry/loader

• Create attachments.ts with:

  • Attachment validation (size, type)
  • File attachment handler
  • Buffer attachment support

• Create scheduler.ts with:

  • Schedule management
  • Retry logic with exponential backoff
  • Job persistence

• Add error handling:

  • RateLimitError, ValidationError, SendError
  • Retry mechanism with backoff
  • Detailed error logging

• Export clean API from index.ts

• Include TypeScript types for all interfaces

• Add JSDoc comments for public methods

Generated files should be in proper directory structure ready for integration.

Expected output: Complete, production-ready email service module with all files")

Phase 5: Review Goal: Verify the generated implementation

Actions:

• Check generated files exist and are properly structured
• Verify TypeScript compilation succeeds
• Example: !{bash cd /home/gotime2022/.claude/plugins/marketplaces/ai-dev-marketplace/plugins/resend && npx tsc --noEmit 2>&1 | head -20}
• Validate templates and attachments handling
• Confirm error handling patterns

Phase 6: Summary Goal: Document what was accomplished

Actions:

• Summarize features implemented:
  • Single email sending with Resend API
  • Batch processing with concurrency control
  • Scheduling support with retry logic
  • Template system with variable substitution
  • Attachment handling with validation
  • Comprehensive error handling
• Highlight key files created
• Note any configuration needed in project setup
• Suggest next steps (testing, integration examples, documentation)
