Golf

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward golf tracker that keeps local notes and does not show hidden, networked, destructive, or deceptive behavior.

Install only if you are comfortable with the agent keeping persistent golf records in ~/golf/. Review round entries before relying on them for handicap or practice advice, and back up important records before archiving or reorganizing old seasons.

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

Missing User Warnings

Medium

Confidence: 93% confidence
Finding: The skill explicitly instructs the agent to update `~/golf/rounds.md` after the user reports a round, which is a proactive write to local user data without any explicit confirmation or warning that files will be modified. In a memory-tracking skill this behavior is functionally relevant, but it still creates a real risk of unintended or silent data modification, especially if the agent over-applies the instruction or writes incorrect entries.

Missing User Warnings

Low

Confidence: 92% confidence
Finding: This markdown file tells the user to create directories and files under `~/golf/`, which affects local filesystem state. The instructions do not include any warning or disclosure that setup will create or modify persistent files on the user's system.

Missing User Warnings

Low

Confidence: 84% confidence
Finding: The archive section instructs the user to move old season data into `~/golf/archive/`, which changes where user records are stored. The markdown does not warn that this operation reorganizes existing files and could affect how users access prior data.
