Reversal — Agent Input Reliability Layer

Security checks across malware telemetry and agentic risk

Overview

This is a disclosed document and URL parsing integration, but users should treat remote mode as sending selected files or URLs to Reversal's service.

Prefer the local stdio setup for confidential files, internal URLs, regulated data, or proprietary documents. If using remote HTTP or the SDKs, assume the selected source and parsed output may be processed by Reversal's service, protect API keys, and review the external repository and service terms before installing.

Missing User Warnings

Medium
Confidence
96% confidence
Finding
The skill documents remote HTTP and SDK usage that sends user-supplied URLs, files, and possibly extracted document content to a third-party service, but it does not clearly warn users about that data egress. In an agent setting, this can cause operators to unintentionally transmit sensitive local files, internal URLs, or proprietary content outside their trust boundary.
