# CricketStudio OKF

> Open, agent-readable cricket knowledge catalog. Curated facts, metric definitions, methodology, and canonical CricketStudio links — designed for AI agents to answer cricket questions with correct scope, provenance, and citation.

CricketStudio OKF is a trusted semantic layer over CricketStudio's canonical cricket data spine. It covers IPL, MLC, players, teams, seasons, metrics, and methodology. Every file carries YAML frontmatter with entity type, source boundary, provenance, and canonical links. Every data-bearing claim states its date window, sample size, and eligibility rules.

This catalog is CC-BY-4.0 (documentation and methodology). Cricsheet-derived content (IPL historical, MLC) is CC BY 3.0. License boundaries are declared per file via `source_boundary`.
