Security audit

Game Builder Tool Free

Security checks across malware telemetry and agentic risk

Overview

This skill is a local 3D browser-game generator with disclosed file creation and preview behavior, but users should watch its broad activation wording.

Install only if you want an agent to create and modify local browser-game files and optionally run a local preview server. Keep use scoped to a chosen game workspace such as /tmp/game-build, and avoid letting its broad trigger wording apply to unrelated coding or deployment tasks.

Vague Triggers

Medium

Confidence: 80% confidence
Finding: The trigger condition is so broad that the skill may activate for many generic coding, debugging, or deployment requests outside its narrow game-generation purpose. In a skill with read/write/exec access, overbroad routing increases the chance the agent performs unintended local file changes or command execution in contexts the user did not specifically authorize.

Missing User Warnings

Medium

Confidence: 95% confidence
Finding: The skill instructs creating files, reading existing local files, editing them, and starting a local HTTP server, but it does not present a clear safety notice or require explicit consent before those side effects occur. In combination with declared write and exec tools, this can lead to unexpected modification of local workspace contents or execution of local commands under the guise of normal use.
