Security audit

XAPS Tollbooth

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed payment-audit helper that sends value-move metadata to XAPS before a user-directed payment action, without installing code or taking custody of funds.

Install only if you are comfortable sending payment-audit details to XAPS and potentially paying the stated external audit fee. Treat the receipt as advisory, as the skill itself says it does not insure, custody, sign, send, settle, or guarantee the transaction.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

- Payees and facilitators **clear** that id themselves (no agent key).
- Refuse value unless `clear` is true, `use_case` is `value_move`, and amount / pay_to / resource match **this** 402.

External cost (Tollbooth, not this skill): about $0.01 per approved payer audit. Register at `POST https://api.xaps.network/agents/register`.

The fee buys an attested decision (`APPROVED` / `REJECTED`) over a `payload_hash`. It is not insurance, not custody, not settlement, and not a warranty that the action is safe. XAPS does not sign, send, or settle the value. A wrong call is a wrong opinion; the agent that executes still owns the loss. Independent `clear` only proves this receipt exists, is `value_move`, and matches this 402 — not that the payment is good.
