• FAISS vector store creation with persistence
• Specialized retrievers for different purposes:
  • Disease Explainer (k=5)
  • Biomarker Linker (k=3)
  • Clinical Guidelines (k=3)

✅ Biomarker Validator

• Validates all 24 biomarkers against reference ranges
• Gender-specific range handling
• Threshold-based flagging (configurable %)
• Critical value detection
• Automatic safety alert generation
• Disease-relevant biomarker mapping

🧬 Evolvable Configuration (ExplanationSOP)

• Complete SOP schema defined
• Configurable agent parameters
• Evolvable prompts
• Feature flags for agent enable/disable
• Safety mode settings
• Model selection options

🔄 State Management

• GuildState: Complete workflow state
• PatientInput: Structured input schema
• AgentOutput: Standardized agent responses
• BiomarkerFlag: Validation results
• SafetyAlert: Critical warnings

🚀 Ready to Use

Installation

# 1. Install dependencies
python setup.py

# 2. Pull Ollama models
ollama pull llama3.1:8b-instruct
ollama pull qwen2:7b
ollama pull llama3:70b
ollama pull nomic-embed-text

# 3. Add your PDFs to data/medical_pdfs/

python src/pdf_processor.py

Test Current Components

# Test biomarker validation
from src.biomarker_validator import BiomarkerValidator

validator = BiomarkerValidator()
flag = validator.validate_biomarker("Glucose", 185, gender="male")
print(flag)  # Will show: HIGH status with warning

# Test LLM connection
from src.llm_config import llm_config, check_ollama_connection
check_ollama_connection()

# Test PDF processing
from src.pdf_processor import setup_knowledge_base
retrievers = setup_knowledge_base(llm_config.embedding_model)

🎓 For Next Session

Before you start coding agents, make sure to:

1. ✅ Place medical PDFs in data/medical_pdfs/

   • Diabetes guidelines
   • Anemia pathophysiology
   • Heart disease resources
   • Thalassemia information
   • Thrombocytopenia guides

2. ✅ Run python setup.py to verify everything

3. ✅ Run python src/pdf_processor.py to build vector stores

4. ✅ Test retrieval with a sample query

Then we'll build the agents! 🚀
