## About

# Enhanced EHR SQL

## 🚨 IMPORTANT: Mandatory Workflow

**YOU MUST FOLLOW THIS WORKFLOW FOR EVERY QUERY:**

1. **FIRST**: Call `skills__initialize(query="", db_path="")`
   - This prepares the skill context and determines the optimal workflow
   - Check the returned `mode` field

2. **IF mode is "enhanced"**, you MUST call these tools in order:
   - `skills__schema_analyzer(db_path="")`
   - `skills__query_builder(db_path="")`
   - `skills__result_formatter(raw_result="")`
   - `skills__verify_results()` before calling finish_task

3. **IF mode is "standard"**, proceed with normal SQL query execution
