Common Skills - Master Reference
Cross-product infrastructure skills that enable persistence, identity correlation, and database operations across all HealthSim products.
Quick Start
# Save your current work
Save this cohort as "demo-patients"
# Load previous work
Load the cohort named "demo-patients"
# Find related entities
Find the member record for patient MRN-12345
# Query the database
Show me all cohorts created in the last week
Core Capabilities
State Management
Persist generated data across sessions with cohort save/load operations. Supports auto-persist for token-efficient batch generation.
Triggers: save, load, persist, resume, snapshot, restore Details: state-management.md
Identity Correlation
Link entities across products using SSN as the universal correlator. Track the same person as patient, member, rx member, and trial subject.
Triggers: find member, link patient, correlate, same person, cross-reference Details: identity-correlation.md
DuckDB Operations
Direct database access for advanced queries, schema exploration, and reference data access.
Triggers: query, SQL, schema, database, show tables Details: duckdb-skill.md
Cross-Product Architecture
Common skills enable data flow between products:
┌─────────────┐ ┌─────────────┐ ┌─────────────┐
│ PatientSim │ │ MemberSim │ │ RxMemberSim │
│ (MRN) │ │ (MBI) │ │ (RxID) │
└──────┬──────┘ └──────┬──────┘ └──────┬──────┘

└────────┬─────────┴─────────┬────────┘

Database Schema
Common skills work with these core tables:
| Table | Purpose | Key Columns |
|---|---|---|
| cohorts | Saved cohort metadata | cohort_id, name, created_at |
| persons | Core person identity | person_id, ssn, demographics |
| patients | PatientSim entities | patient_id, mrn, person_id |
| members | MemberSim entities | member_id, mbi, person_id |
| rx_members | RxMemberSim entities | rx_member_id, rx_id, person_id |
