Skill Creator Attach Info

Security checks for vulnerabilities and agentic risk

Overview

This skill only adds disclosed metadata to newly created skill files, with no hidden code, network use, credential access, or destructive behavior found.

Before installing, understand that this skill may automatically update metadata in SKILL.md when you create a skill. That behavior is disclosed and limited, but users who want manual control over skill headers should adjust the trigger wording or require confirmation before edits.

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
  • 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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger conditions are overly broad because they match common user phrases like '创建技能', '新建技能', and '添加技能' without requiring a clear, scoped context that the request is specifically about skill authoring. This can cause unintended activation and side effects, especially because the skill is defined as mandatory and may modify files automatically after loosely related requests.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill explicitly instructs the AI to proactively and automatically invoke itself in multiple situations, including indirect and file-write-based triggers, with no clear guardrails or ambiguity checks. In an agentic environment, this increases the risk of recursive, unintended, or policy-bypassing behavior and can lead to unauthorized file modifications as part of normal conversation flow.

Skill Enumeration

Medium
Category
Agent Snooping
Confidence
80% confidence
Finding

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

1. **直接触发**:用户说"创建技能"、"新建技能"、"添加技能"、"make a skill"等
2. **间接触发**:调用了 `skill-creator` 技能后
3. **文件创建后**:完成 `.trae/skills/xxx/SKILL.md` 文件写入后

**关键原则**:创建任何技能后,**必须立即**调用本技能添加 Author、Date、BusinessSupportVersion,不得跳过此步骤。
