Single tool with minimal definition quality. Tool name 'execute_skill_action' is generic and violates verb_noun clarity (pattern:tool). Description is 104 chars but vague, does not explain WHAT the skill does, WHEN to use it, or what it returns. Input schema exists but parameter 'query_payload' lacks meaningful description ('Input execution payload' is circular). No output schema documented. No error handling guidance. Tool appears to be a pass-through wrapper with no actual business logic visible, implementation just returns a hardcoded success message regardless of input.

• Rename tool to a specific action verb: 'normalize_product_pricing', 'calculate_tax_by_location', or 'convert_currency_and_tax'. This makes intent clear to LLMs without reading the description.
• Rewrite description to explain the business function: 'Calculates local currency price and applicable tax rate for a product based on destination country and postal code. Returns net amount, tax, total, and VAT compliance status.' (target 100-150 chars).
• Document 'query_payload' parameter: specify format (JSON object? string? key-value pairs?), required fields (country, postal_code, base_price_usd?), and constraints (e.g., 'ISO 3166-1 alpha-2 country code').
• Add output schema documentation: describe the response object with field names, types, and meanings. E.g., 'Returns {local_currency: string, local_total_payable: number, applicable_tax_rate: number, nexus_compliance_status: string}'.
• Wire the actual client.py logic into the MCP tool handler. Currently, tools/call returns a stub. Implement real currency conversion and tax calculation based on query_payload parameters.
