Risk Level: SAFEPROMPT_INJECTIONCOMMAND_EXECUTION
Full Analysis
  • [COMMAND_EXECUTION]: The skill invokes local CLI commands such as shinkoku tax calc-income and shinkoku import import-withholding to manage tax data and calculations. These commands are part of the vendor's specialized toolset and operate on local JSON inputs.
  • [PROMPT_INJECTION]: The skill is susceptible to indirect prompt injection due to its document processing workflow.
  • Ingestion points: External data enters the context via OCR extraction from documents like withholding slips and insurance certificates.
  • Boundary markers: The prompt does not specify the use of delimiters or 'ignore' instructions for the data extracted from OCR.
  • Capability inventory: The skill can execute shell commands via the shinkoku tool and perform file operations using Read/Write tools.
  • Sanitization: Although the skill uses a dual-verification mechanism to ensure the correctness of extracted numbers, it lacks specific sanitization or filtering to prevent the interpretation of malicious instructions embedded in document text.
