Implement @lytics/playwright-agent package with subagent architecture

[prosdev]

Branch: feat/implement-agent-package

Priority: High

Estimate: 4-5 hours

Parent Epic: #1

Dependencies: #2, #4

Description

Create a new @lytics/playwright-agent package that implements an agent-based approach to test automation. This package will provide a framework for intelligent agents that can analyze tests, generate code, and provide insights based on annotation metadata. It will extend the annotation-driven architecture with automation capabilities that help teams write better tests.

Acceptance Criteria

• Create new @lytics/playwright-agent package with proper TypeScript setup
• Implement core agent interface that integrates with annotations
• Create subagent architecture for specialized test automation tasks
• Implement at least 3 subagents (analyzer, generator, validator)
• Add LLM provider integrations (OpenAI, Anthropic)
• Create CLI for interacting with agents
• Build comprehensive unit tests
• Document agent integration and usage
• Publish to npm registry

Technical Requirements

Core Agent System

• Create base agent interface and implementation
• Build agent configuration system
• Implement agent registration and discovery
• Add event system for agent communication
• Create agent result types that work with reporter

Subagent Implementation

• Create AnalyzerSubagent for test quality analysis
• Build GeneratorSubagent for test generation based on journeys
• Implement ValidatorSubagent for annotation validation
• Add OrchestratorSubagent to coordinate between agents
• Create extensible subagent architecture for future additions

LLM Integration

• Add provider interfaces for different LLM services
• Implement OpenAI provider for GPT models
• Add Anthropic provider for Claude models
• Create prompt templates for test-specific tasks
• Implement caching to reduce API costs

CLI and Integration

• Build command-line interface for agent operations
• Add interactive mode for real-time assistance
• Create code generation commands
• Implement analysis commands for existing tests
• Add integration hooks for reporter and adapters
