Security audit

Workspace Guardian

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple workspace-organization guide, with disclosed file cleanup behavior but no hidden code, network access, persistence, or credential handling.

Install only if you want the agent to enforce a project folder structure and clean up temporary or rejected generated files. If you need to keep drafts, rejected outputs, or temp files for audit or recovery, tell the agent explicitly before using the skill.

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
Vulnerability Patterns
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The skill instructs automatic removal of rejected outputs ('remove the file promptly') without requiring an explicit confirmation, recycle/trash behavior, or warning about irreversible data loss. In an agent context, a 'rejected' result may still contain useful work product or may be rejected accidentally, so this can lead to unintended destruction of user data.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The instruction to clean up temp/ after task completion authorizes automatic deletion without specifying user notice, retention period, or safeguards against misclassification of important files as temporary. In a workspace-management skill, broad cleanup behavior is more dangerous because the agent is explicitly entrusted with file lifecycle decisions across projects.

Natural-Language Policy Violations

Confidence

Finding

The file contains user-facing text in Chinese, including the cleanup prompt, despite the rest of the skill being written in English. This imposes a language choice without user opt-in and may violate language or locale policy expectations.
