Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed TDD workflow helper that can run local development commands and create local Git commits, with no evidence of hidden exfiltration, persistence, or destructive behavior.

Install this only for repositories where you are comfortable letting the agent run local development commands, edit code and plan files, run formatters, and create local Git commits. Review changes before pushing them or using it on sensitive projects.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill advertises automatic task execution, code commits, and plan-file updates without an explicit upfront warning that it will modify repository contents and Git history. In a tool with read and exec permissions, silent or insufficiently disclosed state changes are dangerous because users may trigger destructive or hard-to-reverse actions without informed consent.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The scope language is overly broad and includes generic project-management and automation scenarios, which increases the chance the skill will activate in contexts beyond its intended use. Because the skill has exec capability and can modify plans, code, and Git state, over-broad triggering raises the risk of unintended command execution and repository changes from ambiguous user requests.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill claims no extra API key is needed because it only uses local Git and file operations, but it also explicitly depends on an external LLM API provided by the agent platform. This can mislead users about trust boundaries, data exposure, and operational dependencies, causing them to run the skill without understanding that repository contents or prompts may be sent to a remote model service.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The license section states the skill is '完全中文化表达,适配中文独立开发者工作流', indicating a fixed language/locale orientation. There is no accompanying language choice, opt-in, or explicit justification that the tool is region-specific, so this is a natural-language locale policy concern.
