Single tool 'execute_skill_action' has a minimal description (97 chars) that lacks actionable context for LLM selection. Input schema is present but parameter 'query_payload' has only a generic description ('Input execution payload for this skill') with no format, constraints, or examples. No output schema is documented, the tool returns a hardcoded JSON string with no structure definition. No error handling guidance, no parameter validation rules, and no indication of what 'deterministic, zero-dependency' operations actually entails. The tool name uses a generic verb ('execute') rather than a domain-specific action (e.g., 'execute_merchant_operation' or 'process_supply_chain_action'). Overall, this reads as a stub implementation rather than a production-ready tool.

• Document the output schema explicitly. Define the structure of the success response (e.g., status, message, operation_id, result_data) and document all possible error responses with actionable recovery guidance.
• Enhance the tool description to 150 - 250 characters. Explain: (1) What specific merchant/supply-chain operations this executes, (2) When to call it vs. other tools, (3) What the LLM should expect in the response. Example: 'Execute GenPark merchant operations (inventory sync, order routing, fulfillment) verified by AI. Returns operation_id and status. Use for deterministic supply-chain tasks.'
• Add format and constraint documentation to 'query_payload'. Specify: Is it JSON? Plain text? What fields does it expect? What is the max length? Provide a concrete example structure (without sample values) so LLMs know what to construct.
• Rename the tool to a domain-specific action verb. Instead of 'execute_skill_action', use 'execute_merchant_operation' or 'process_supply_chain_action' so the name alone signals intent.
• Implement error classification and recovery guidance. Return distinct error types (e.g., 'invalid_payload', 'operation_timeout', 'permission_denied') with actionable next steps for each. Example: 'Invalid payload format. Expected JSON with fields: operation_type, merchant_id, payload. See docs at [URL]'.
