Game Development

Security checks for vulnerabilities and agentic risk

Overview

This skill provides coherent game-development guidance with disclosed local note storage and no evidence of hidden execution, exfiltration, or unsafe persistence.

Before installing, expect the skill to maintain local project memory files under ~/game-development/. Review or remove those notes if you do not want cross-session game-planning context saved; use explicit approval for any repository push, asset upload, telemetry, analytics, backend, or related-skill installation.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Sudo/Root Execution

Medium
Category
Privilege Escalation
Content
```bash
mkdir -p ~/game-development
touch ~/game-development/{memory.md,concept-briefs.md,user-preferences.md,system-decisions.md,playtest-log.md,roadmap.md,release-notes.md}
chmod 700 ~/game-development
chmod 600 ~/game-development/{memory.md,concept-briefs.md,user-preferences.md,system-decisions.md,playtest-log.md,roadmap.md,release-notes.md}
```
Confidence
80% confidence
Finding
Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.

Missing User Warnings

Low
Confidence
91% confidence
Finding
The skill explicitly instructs creation of files under `~/game-development/`, which is a filesystem write action. Even though the target path is user-scoped and the content is benign note-taking scaffolding, writing files without an explicit user warning or consent can still cause unintended persistence or overwrite local data in agent-enabled environments.
