Executive Summary

The AI Service Registry is a workflow orchestration system designed to chain multiple AI services together for complex processing tasks. Instead of relying on a single AI service, it enables sophisticated pipelines where different services contribute their specialized capabilities.

Key Value Propositions:

• Service Specialization: OpenAI for language tasks, Grok for analysis
• Workflow Composability: Chain services for multi-step processing
• Fallback & Reliability: Automatic failover between services
• Cost Optimization: Choose optimal service based on task requirements
• Extensibility: Easy integration of new AI providers

Current State:

• Working: Basic service registration and selection
• Limited: Currently configured for legacy crypto analysis
• Potential: Can be adapted for modern workflows (document processing, content creation, research)

Architecture Overview

Core Components

Registry Structure

Service Selection Logic

⚠️ Critical Insight: The registry returns the first registered service, not the last. This affects service precedence.

Service Initialization

The registry is initialized at application startup:

⚠️ Issue: Grok doesn't override OpenAI for GENERIC_ANALYZER due to registration order.

Service Chaining Patterns

Pattern 1: Sequential Processing

Use Case: Document Analysis Pipeline

Pattern 2: Parallel Processing

Separation of Concerns

Idempotency

2. Error Handling Patterns

Graceful Degradation

Circuit Breaker Pattern

3. Monitoring & Observability

Troubleshooting

Common Issues

1. "No service available for type X"

Symptoms: ServiceUnavailableError when requesting specific service type

Diagnosis:

Solutions:

• Ensure service is properly registered during initialization
• Check if service initialization failed due to missing API keys
• Verify service type enum values match registration

2. "Request timeout" / "502 Bad Gateway"

Symptoms: Long processing times followed by timeout errors

Diagnosis:

Solutions:

• Increase timeout values in environment variables
• Check API key validity and quotas
• Verify network connectivity to AI service providers
• Monitor service logs for specific error messages

3. "Invalid input for [Service] processing"

Symptoms: Input validation failures, often with optimized prompts

Diagnosis:

Solutions:

• Increase MAX_USER_INPUT_LENGTH environment variable
• Implement bypass validation for optimized prompts
• Add separate validation limits for internal processing

4. Wrong service being selected

Symptoms: Expected Grok but got OpenAI, or vice versa

Diagnosis:

Solutions:

• Modify service registration order
• Use specific service selection instead of preferred
• Implement service selection logic in frontend
