Risk Level: HIGHPROMPT_INJECTIONCOMMAND_EXECUTION
Full Analysis
  • [Indirect Prompt Injection] (HIGH): The skill processes untrusted user input to generate file content and executable scripts. This creates a vulnerability where malicious prompts can lead to the creation of skills with dangerous capabilities.
  • Ingestion points: User instructions and examples provided during the /create-skill command trigger.
  • Boundary markers: Absent. The instructions do not define delimiters to separate user input from generated instruction logic.
  • Capability inventory: The skill utilizes Write tool to create files and encourages the creation of scripts/ (executable code) and the use of Bash via allowed-tools.
  • Sanitization: Absent. There are no instructions for validating or escaping user-provided examples before including them in the generated skill.
  • [Command Execution] (MEDIUM): The skill explicitly instructs the agent to create executable scripts in a scripts/ directory and test them. It also suggests configuring frontmatter to allow Bash(git:*) access, which provides a pathway for arbitrary command execution in the resulting skills.
