// WHEN AI AGENTS USE THIS TOOL

AI agents use pay_upgrade to initiate financial transactions through Srv D7aoqmh5pdvs7391dcqg. Financial operations involve real money and are irreversible once processed. Intercept blocks financial tools by default, requiring explicit human approval with transaction-level limits to prevent unauthorised spending.

// WHY ENFORCE A POLICY ON PAY_UPGRADE

pay_upgrade moves real money. Without a policy, an autonomous agent could initiate transactions that drain accounts or exceed budgets. Intercept blocks financial tools by default, requiring human-in-the-loop approval with configurable spending limits per transaction and per time window.

// RECOMMENDED POLICY

Financial tools involve real money. Block by default and require explicit human approval before enabling.
