Proto Cog

Security checks across malware telemetry and agentic risk

Overview

Proto Cog is a disclosed CellCog-based UI prototyping skill whose main risk is sending prototype content to an external service that hosts shareable outputs.

Install only if you are comfortable sending prototype prompts, UI copy, sample data, and generated output to CellCog. Avoid secrets, customer data, internal-only product plans, realistic credentials, or regulated data in prompts or prototypes, and review hosted links before sharing them.

Vague Triggers

Medium
Confidence
88% confidence
Finding
The skill description is broad enough to match many generic UI, design, and prototyping requests, which can cause the agent to invoke this external-service skill in situations where a more constrained or local tool would be safer. Because the skill sends prompts to CellCog and may generate hosted outputs, overbroad routing increases the chance of unnecessary disclosure of user content to a third-party service.

Missing User Warnings

Medium
Confidence
96% confidence
Finding
The skill advertises that prototypes are hosted on live URLs but does not warn that prompts, embedded text, sample data, or uploaded assets may become exposed through those hosted artifacts. In this context, the omission is materially dangerous because users may include product plans, internal names, credentials, customer-like data, or other sensitive information in prototype requests without realizing the output is shareable and externally hosted.
