Server has 9 tools with basic descriptions and input schemas, but significant quality gaps. Most tool names lack clear action verbs (e.g., 'audit_dns_records' is acceptable, but 'get_live_dns_throughput_metrics' is vague). Descriptions are present but generic (avg ~80 chars, below 194-char baseline). Parameter descriptions are minimal or missing context. Output schemas are not documented, responses are JSON strings without declared structure. No error handling guidance. Tool #7 (calculate_technical_seo_security_score) takes computed inputs rather than performing discovery, violating single-responsibility. Tool #8 (sanitize_audit_payload) is a utility, not a domain tool. No pagination, no result limits documented. Security headers tool returns a score but no actionable remediation guidance.

• Document output schemas for all tools. Define the structure of returned JSON (field names, types, required fields). Example: audit_dns_records returns {status: string, domain: string, dns_records: {ip_addresses: string[], has_a_record: boolean, error?: string}}.
• Refactor tool #7 (calculate_technical_seo_security_score) to accept a domain_name and internally call audit_http_security_headers, check_ssl_tls_certificate, etc., then compute the score. This makes it a discoverable, single-responsibility tool.
• Add error recovery guidance to all tools. Replace generic 'ERROR' responses with actionable messages: 'Domain resolution failed: check domain spelling or try a different domain. If the domain is valid, the DNS server may be unreachable.'
• Enhance parameter descriptions with format constraints. E.g., domain_name: 'Target domain name (e.g., seosiri.com). Must be a valid FQDN without protocol prefix (https:// will be stripped). Subdomains are supported.'
• Add a description to tool #9 and rename it to clarify intent. E.g., 'get_server_health_metrics' with description: 'Returns operational health and performance metrics for the DNS audit server (uptime, request count, average latency).' Add output schema documenting returned fields.
