Server has 6 tools with basic schemas and descriptions, but significant quality gaps. Tool names lack action verbs (verify_erid, lookup_erid, audit_ad_page, check_compliance_38fz, explain_topic, audit_batch). Descriptions are present but many are in Russian and several tools explicitly state they are NOT implemented ('ещё не подключены'). Input schemas exist but are minimal, most parameters lack detailed constraints, ranges, or format guidance. Three tools (audit_ad_page, check_compliance_38fz, audit_batch) are stubs that return honest refusals rather than functional implementations. No output schemas documented. Error handling is present in code but not reflected in tool definitions. No tool annotations (readOnlyHint, destructiveHint, idempotentHint).

• Rename tools to follow verb_noun pattern: verify_erid → check_erid_format, lookup_erid → search_erid_in_cabinet, audit_ad_page → audit_ad_page_marking, check_compliance_38fz → check_38fz_compliance, audit_batch → audit_ad_pages_batch.
• Remove or disable the three unimplemented tools (audit_ad_page, check_compliance_38fz, audit_batch) from the tool list. If they must remain, add a 'status' field to tool metadata indicating 'not_implemented' and document the roadmap.
• Document output schemas for all tools. Example for verify_erid: {type: 'object', properties: {valid: {type: 'boolean'}, format_errors: {type: 'array', items: {type: 'string'}}, disclaimer: {type: 'string'}}}.
• Add enum constraints to explain_topic's 'topic' parameter: enum: ['erid', 'ord', 'erir', 'responsibility', 'deadlines', 'fines']. Add pattern and maxLength to erid parameters (e.g., pattern: '^[A-Za-z0-9]{9,}$').
• Translate all tool descriptions and parameter descriptions to English. Provide Russian translations as secondary documentation, not in the tool schema itself.
