Agent Financial Guard — Pre-Sign Evidence Review

{
  "name": "Agent Financial Guard \u2014 Pre-Sign Evidence Review",
  "description": "External application-level evidence gate for agent workflows. Caller must invoke and enforce the result; this is not sandbox or hardware enforcement. Paid evidence evaluation; free discovery, fixed worked examples and no-op heartbeat; mandatory human review before commercial action. No independent factual verification or clearance. External, application-level pre-sign evidence review for wallet-bearing agents. Checks a local risk denylist, approval patterns and intent; caller-reported spending history is unverified. Non-rejected transactions require human review. No transaction authorization or current sanctions clearance. New to these gates? Start with the Corridor & Sanctions Risk Assistant (https://corridor-sanctions-assistant-a2a.vassiliy-lakhonin.workers.dev) for plain-language orientation. Describe the route or counterparty and the next decision or review; fit, scope, fee, and timing are confirmed before work starts.",
