Single tool 'execute_skill_action' has a generic, vague description (92 chars) that fails to explain WHAT the tool does, WHEN to use it, or what it returns. Parameter 'query_payload' is a free-form string with minimal guidance, no format, constraints, or examples. No output schema is documented. The tool name uses 'execute' (generic verb) + 'skill_action' (vague noun), violating verb_noun clarity. No error handling, no pagination, no structured response guidance. The implementation echoes input as JSON but provides no actionable schema for LLM planning. This server falls well below production baselines (avg tool description 194 chars, 100% of A+ tools document output schemas).

• Rename tool to a specific action verb + noun pair. Examples: 'enrich_prospect' (if it enriches B2B records), 'validate_email' (if it validates emails), 'lookup_company' (if it queries company data). Avoid 'execute' and 'skill_action'.
• Rewrite description to 50 - 200 chars, answering: What does it do? When should I call it? What does it return? Example: 'Enrich a B2B prospect record with company firmographics, employee count, funding stage, and verified email. Call this after you have a domain or email. Returns structured prospect data with confidence scores.'
• Replace 'query_payload' string parameter with explicit, typed parameters (e.g., 'email', 'domain', 'first_name', 'last_name', 'title'). Add enums for known fields (e.g., title: ['CEO', 'CTO', 'VP Sales', ...]). Document format and constraints in each parameter description.
• Document the output schema explicitly in the tool definition. Specify field names, types, and meanings. Example: '{"status": "success|error", "prospect": {"email": string, "company_name": string, "confidence": number 0 - 1, ...}, "audit_trail": [...]}'.
• Add error handling: return structured errors with classification (retryable, user-fixable, fatal) and recovery guidance. Example: 'Invalid email format. Try passing a valid business email (e.g., [email protected]) or a domain (e.g., acme.com).' instead of a generic failure.
