// WHEN AI AGENTS USE THIS TOOL

AI agents use printr_transfer to initiate financial transactions through Printr. 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 PRINTR_TRANSFER

printr_transfer 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.

io-github-printrfi-printr.yaml

tools:
  printr_transfer:
    rules:
      - action: deny
        reason: "Requires human approval"
