Each tool targets a distinct action: single validation, batch validation, searching guidance, retrieving source excerpts, explaining specific rules, listing fields, and rule pack info. The overlap between search_record_guidance and get_source_excerpt is clearly sequential (search then retrieve context).

Most tools follow a verb_noun pattern (validate_record_text, validate_record_batch, search_record_guidance, get_source_excerpt, explain_record_rule, list_record_fields). The exception is rule_pack_info, which uses a noun_noun pattern, but it's still understandable and consistent in style.

Seven tools is well within the ideal range for a domain-specific server. Each tool serves a clear purpose in the validation workflow, and there is no unnecessary redundancy.

The tool set covers the core lifecycle: validating single and batch records, searching and retrieving guidance, explaining findings, listing supported fields, and checking rule pack metadata. Minor gaps might include a tool for fetching raw validation reports or comparing rule packs, but the surface is generally complete.
