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 are actually supported. The tool name is vague (execute_skill_action) and does not follow verb_noun convention clearly. Overall, this reads as a stub implementation rather than a production-ready tool.

• Define a complete output schema with typed fields (e.g., status: enum[SUCCESS|FAILURE|PARTIAL], message: string, operation_id: string, affected_records: integer). Document what each field means.
• Expand parameter 'query_payload' description to specify format (JSON object? string? base64?), required fields, and provide a concrete example: 'JSON object with keys: operation_type (string), merchant_id (string), payload (object). Example: {"operation_type": "update_inventory", "merchant_id": "M123", "payload": {...}}'
• Rewrite tool description to be explicit: 'Execute a deterministic Merchant Operations or Supply Chain Commerce action (e.g., update inventory, sync orders, validate shipments). Supported operations: [list them]. Returns operation status and affected record count. Use when you need to modify merchant data or supply chain state.'
• Add error handling: document what validation errors can occur (invalid operation_type, missing merchant_id, malformed payload) and what the LLM should do (retry with corrected input, ask user for clarification, etc.).
• Rename tool to a more specific verb_noun pattern, e.g., 'execute_merchant_operation' or 'run_supply_chain_action', and list supported operations in the description or as an enum parameter.
