Security audit

Receipt Logger

Security checks for vulnerabilities and agentic risk

Overview

This appears to be a transparent audit-log skill, but the package is incomplete because the advertised receipt-logger executable is missing.

Before installing, verify the publisher supplies the missing receipt-logger executable or the skill will likely not work as advertised. If you use it, avoid logging secrets, credentials, or private content because receipts are intended to persist and be exportable.

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
