A4/5.0

Scored across 8 tools

Disambiguation5/5

Each tool has a clearly distinct purpose with no overlap: batch_generate_invoices handles multiple invoices, while generate_invoice, generate_advance, generate_duplicate, and generate_proforma target specific invoice types; lookup_nbp and lookup_nip provide external data; and preview_invoice offers a calculation preview. The descriptions explicitly differentiate between invoice types (e.g., VAT vs. proforma vs. advance), ensuring no confusion.

Naming Consistency5/5

All tool names follow a consistent verb_noun pattern using snake_case, starting with a descriptive verb (e.g., generate, lookup, preview) followed by a specific noun (e.g., invoice, advance, nip). This uniformity makes the tool set predictable and easy to navigate, with no deviations in style or convention.

Tool Count5/5

With 8 tools, the count is well-scoped for the server's purpose of handling Polish invoices and related data. Each tool earns its place by covering key operations: generating various invoice types, batch processing, data lookups, and previews, without being overly sparse or bloated for the domain.

Completeness4/5

The tool set provides comprehensive coverage for generating and managing Polish invoices, including different invoice types (VAT, advance, duplicate, proforma), batch operations, data lookups (NBP rates, NIP info), and a preview function. A minor gap is the lack of tools for updating or deleting invoices, but this is reasonable as invoices are typically immutable documents, and agents can work around this by regenerating as needed.
