Security checks for vulnerabilities and agentic risk

Overview

This skill generates a local creative-writing HTML app and does not show hidden, destructive, credential-seeking, or network behavior.

Installers should expect this skill to create or overwrite a local HTML app file when invoked. Use explicit prompts and specify an output path if you want to avoid accidental writes from broad trigger phrases.

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

Finding

The trigger set includes highly generic phrases such as '创意写作', '写作灵感', and '写作应用', which are common in ordinary conversation and can cause the skill to activate when the user did not intend to generate and write a full HTML file. Because this skill performs autonomous artifact generation, accidental activation can lead to confusing behavior and unintended file creation.

Vague Triggers

Confidence

Finding

The invocation list includes short or context-light forms like '生成642' and references to '642件事', which are ambiguous and may match unrelated requests involving the number 642 rather than this specific skill. In a skill that automatically executes a workflow, ambiguous shorthand increases the chance of unintended activation and downstream side effects.

Missing User Warnings

Confidence
96% confidence
Finding

The skill directs the agent to write a file to a default workspace path automatically, and the document emphasizes that the bot should execute the workflow directly without requiring extra user input. Automatic file creation without an explicit confirmation or dry-run preview is risky because accidental activation or path misunderstandings can modify the workspace unexpectedly.
