Folder Cleanup Assistant

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent folder-cleanup assistant that discloses local file scanning and file moves, requires backups and confirmation, and does not include hidden code or persistence mechanisms.

Before installing, be aware that this skill is intended to inspect and reorganize local folders. Use it only on a specific folder you choose, review the proposed file list carefully, and keep the generated backup until you are sure the moved files are no longer needed.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The trigger keywords include broad, everyday phrases such as '清理文件' and 'organize files', which can cause the skill to activate in contexts where the user did not intend to invoke filesystem-cleanup behavior. Because this skill is designed to inspect and potentially move large sets of local files, accidental activation materially increases the risk of unintended sensitive file enumeration or destructive file reorganization.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The skill name/description and all operational instructions are written to position the skill as Chinese-language only, with no indication that the user may choose another language. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation unless the locale restriction is explicitly justified, which is not present here.

Session Persistence

Medium
Category
Rogue Agent
Confidence
87% confidence
Finding

The skill instructs persistent movement of user files into a fixed trash-like directory under the user's home directory, creating lasting side effects on the local system. This persistence can accumulate sensitive or important files outside their original locations, and if the target directory is reused across runs without isolation, users may lose track of moved data or expose it to other local processes and users depending on host configuration.
