Security checks across malware telemetry and agentic risk

Overview

This appears to be a recipe lookup skill that sends dish or ingredient terms to a disclosed external recipe API, with no evidence of hidden persistence, credential access, or destructive behavior.

Before installing, be comfortable with dish names or ingredient lists being sent to api.yummy.chat. Avoid using it with sensitive personal context, and prefer clear recipe requests so the skill is not invoked during general food conversation.

Vague Triggers

Medium
Confidence
91% confidence
Finding
The top-level description uses broad terms like cooking, ingredients, dish, meal, and cuisine, which can cause the skill to activate for general food-related conversation rather than clear recipe-intent requests. Over-broad activation can route unrelated user prompts to a tool-using skill, increasing unnecessary external calls and unintended data disclosure to the third-party API.

Vague Triggers

Medium
Confidence
89% confidence
Finding
The 'When to Use This Skill' section contains vague cues such as 'want to eat X' and broad keyword matching, without guardrails for when the user is merely discussing food rather than requesting a recipe lookup. This makes accidental invocation more likely and can trigger unnecessary network requests to an external service based on weak intent signals.
