## Why razz_create_challenge is rated Critical

This tool initiates a real-money wager in SOL cryptocurrency as part of a game challenge. Committing a financial stake against another player constitutes a financial obligation/transaction. If the opponent accepts, real SOL changes hands. Even if refunded on timeout, the act of sending the challenge locks up real funds, placing this firmly in the Financial category, which supersedes Execute or Write.

From the tool's own definition: "'real SOL wagering', 'any wager is refunded' (implies real wager committed), 'Challenge another player to RPS'"

## Use case

AI agents use razz_create_challenge to commit financial operations through Razz Games, usually the final step of a payment, billing, or trading workflow. A call moves real money.
