Security checks across malware telemetry and agentic risk

Overview

This skill is a narrow, disclosed daily-post fetcher that makes one unauthenticated GET request and shows no hidden access, persistence, or credential handling.

Install only if you are comfortable with daily-post-like prompts automatically contacting the listed ngrok URL. Treat returned endpoint content as untrusted web content, not as instructions for the assistant to follow.

Vague Triggers

86% confidence
Finding
The skill advertises multiple natural-language trigger phrases plus an open-ended “or similar” instruction, which can cause the agent to invoke the skill on loosely related user requests. Because invocation is set to auto and the skill performs an outbound HTTP request immediately, unintended activation could lead to unnecessary network access and disclosure of endpoint responses to the chat.
