Overview
An EligibilityFragment encodes conditional access rules for public benefits, services, or programs in a structured, retrievable, and explainable format. These fragments allow AI agents to evaluate user input, navigate eligibility logic, and return trustworthy outcomes aligned with glossary and provenance references.
Purpose: To enable agentic systems to evaluate and explain program eligibility with structured logic and source-scoped definitions.
Common Applications:
- Public benefit eligibility (SNAP, Medicaid, housing)
- Insurance qualification flows
- Student aid screening
- Government program onboarding
- Policy-based access rules

Why EligibilityFragments Matter
- Retrievable: Makes access rules AI-discoverable and usable
- Explainable: Logic is structured and transparent
- Composable: Can be linked to plan pages, onboarding tools, or agent workflows
- Glossary-Aligned: Every term can be scoped to trusted definitions
- Federatable: Ideal for civic publishing across jurisdictions
