TDQS
Scored across 6 tools
Each tool targets a distinct resource and action: searching by metadata, searching by text keyword, retrieving revision history, retrieving law data, fetching attachments, and downloading law files. Even get_law_data and download_law_file are clearly differentiated by return type (structured JSON vs. saved file path).
All tool names follow a consistent verb_noun pattern in snake_case (search_laws, get_law_revisions, get_law_data, get_attachment, search_keyword, download_law_file). The verb choices are simple and predictable, with no mixed conventions.
Six tools is well-scoped for a legal information API, covering search, revisions, data retrieval, attachments, keyword search, and file download without redundancy or bloat. The count feels appropriate for the domain.
The tool surface covers the main operations of the e-Gov law API: law list searches, keyword text searches, revision history, law data retrieval, attachments, and file downloads. As a read-only API, there are no obvious dead ends or missing core workflows.
