BUG: Pet Clinic Agents are recommending products that we don't offer or that doesn't exist

[liustve]

Hi @awsapm can you help look into this?

🚨 ROOT CAUSE ANALYSIS: Pet Clinic Chatbot Recommending Non-Existent Products

CRITICAL FINDINGS:

1. NUTRITION SERVICE DATA GAPS (HIGH SEVERITY)
   • Issue: The nutrition service backend has incomplete pet data coverage
   • Evidence:
   • GET /nutrition/rabbit returns 404 Not Found (statusCode: 404)
   • Nutrition agent logs show: "Error: Nutrition service could not find information for pet: rabbit"
   • Similar errors for birds and other pet types

2. AI AGENT HALLUCINATION (HIGH SEVERITY)
   • Issue: When the nutrition service fails, the AI agents fabricate product recommendations
   • Evidence:
   • Agent recommends "AvianVital Mineral Supplement", "ScaleStrong Calcium Boost", "ReptileVitality D3 Formula"
   • Agent recommends "HoppyHerb Rabbit Pellets", "RabbitVital Wellness Drops"
   • These products don't exist in your actual inventory

3. SYSTEM ARCHITECTURE PROBLEM (HIGH SEVERITY)
   • Issue: Poor error handling between services causes AI hallucination
   • Evidence:
   • 12.50% fault rate in nutrition_agent.DEFAULT
   • 185 error occurrences detected in logs
   • KeyError exceptions in agent processing

OPERATIONAL RECOMMENDATIONS:

IMMEDIATE ACTIONS (Fix Today):

1. Update Nutrition Service Database
   • Add missing pet type data for: rabbit, birds, and other missing animals
   • Ensure all pet types your clinic serves have corresponding nutrition data
   • Verify database completeness against your actual service offerings

2. Implement Proper Error Handling
   • Configure agents to respond with "I don't have that information available" instead of fabricating products
   • Add validation to prevent product recommendations when data is unavailable
   • Implement fallback responses that direct customers to speak with veterinarians

3. Agent Configuration Adjustment
   • Update agent prompts to be more conservative when data is missing
   • Remove or modify the instruction to "always recommend specific product names"
   • Add explicit instructions to not fabricate product information

MONITORING IMPROVEMENTS:

4. Set Up SLO Monitoring
   • Create SLOs for nutrition service availability (target: >99%)
   • Monitor agent error rates (target: <1%)
   • Set up alerts for 404 responses from nutrition service

5. Enhanced Logging
   • Add structured logging for product recommendations
   • Track when agents fall back to generic responses
   • Monitor customer satisfaction with chatbot responses

INFRASTRUCTURE OPTIMIZATIONS:

6. Service Reliability
   • Address the 95ms latency spikes in nutrition service
   • Optimize MongoDB queries (currently showing 28ms query times)
   • Consider caching frequently requested pet nutrition data

7. Agent Performance
   • Reduce the 84-second latency in pet clinic agent calls
   • Optimize the agent-to-agent communication path
   • Consider implementing circuit breakers for failed service calls

VERIFICATION STEPS:

1. Test Coverage: Verify nutrition data exists for all pet types your clinic serves
2. Agent Testing: Test chatbot responses for edge cases and missing data scenarios
3. Product Validation: Ensure all recommended products actually exist in your inventory
4. Customer Communication: Consider notifying recent customers who received incorrect product recommendations

This issue is causing customer confusion and potentially lost sales. The immediate priority should be fixing the data gaps and preventing AI hallucination of non-existent
products.

Root Cause Analysis: Pet Clinic Chatbot Issues

Critical Findings

1. Nutrition Service Data Coverage Gaps
   • Missing pet type data (rabbit, birds, etc.) causing 404 responses
   • 12.50% fault rate in nutrition_agent.DEFAULT
   • 185 error occurrences detected

2. AI Agent Hallucination
   • Agents fabricating non-existent products when data unavailable
   • Recommending "AvianVital", "HoppyHerb" products not in inventory
   • Poor error handling between services

3. Performance Issues
   • 84-second latency in pet clinic agent calls
   • 95ms latency spikes in nutrition service
   • 28ms MongoDB query times

Immediate Actions Required

Data Fixes:
• Add missing pet nutrition data for all supported animals
• Verify database completeness against clinic services
• Test nutrition endpoints for all pet types

Agent Configuration:
• Update prompts to avoid product fabrication
• Implement "information not available" fallback responses
• Add validation before product recommendations

Monitoring Setup:
• Create SLOs for nutrition service (>99% availability)
• Monitor agent error rates (<1% target)
• Alert on 404 responses from nutrition service

Technical Recommendations

Service Reliability:
• Optimize MongoDB queries and add caching
• Implement circuit breakers for failed calls
• Reduce agent-to-agent communication latency

Error Handling:
• Add structured logging for recommendations
• Implement graceful degradation patterns
• Direct customers to veterinarians when data missing

This requires immediate attention to prevent customer confusion and maintain service reliability.

@awsapm can you edit that PR and not add any new pet type information? We don't want to make up pets we don't support.
