About this plugin

Language models often struggle with check-digit arithmetic, leading to incorrect checksums for generated credit cards or ISBNs. The DeepSeek Harness dsh-checkdigit plugin solves this by implementing pure integer arithmetic based on published specifications. It ensures deterministic, offline computation with zero runtime dependencies, eliminating common LLM hallucinations. With core capabilities to generate, validate, and detect check digits across 11 standard algorithms—including Luhn, Verhoeff, Damm, ISBN, EAN, and ISIN—it provides a solid mathematical foundation for developers working with financial and identity identifiers.

Use Cases

  • Generate test credit card numbers
  • Validate ISBN and barcodes
  • Generate securities identifiers or bank accounts

Best For

  • DeepSeek Harness plugin developers
  • AI engineers needing accurate math data
  • Software engineers handling financial data
