It performs no side effects, creates no transactions, moves no funds, and makes no modifications. Despite operating in a financial context (Lightning Wallet/Bitcoin), the tool itself is strictly informational/read-only. From the tool's own definition: "Tool name 'get_budget_status' and description 'Get budget status for an agent - shows limit, spent, and remaining' indicate a read-only query operation that retrieves financial status information without modifying any data or executing transactions." ## Use case AI agents call get_budget_status to retrieve information from Lightning Wallet without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**.
