Delegated payment-approval blast radius

Through the delegation edge, ChiefOfStaffBot can reach the finance_bot, which directly holds the approve_payment tool. Consequently, any user or process that can invoke ChiefOfStaffBot inherits the ability to trigger payment approvals via finance_bot. The practical blast radius therefore extends to all payment transactions that finance_bot is authorized to approve, creating a critical risk of unauthorized or fraudulent payments if the delegation is not tightly controlled.

Recommended actionConduct an immediate access review of the delegation relationship between ChiefOfStaffBot and finance_bot. Restrict delegation to only verified, least‑privilege identities, enforce multi‑factor approval for payment actions, and implement monitoring/auditing of all approve_payment invocations originating from ChiefOfStaffBot.
