Single tool 'execute_skill_action' has a minimal description (95 chars) that lacks actionable context for LLM selection. Input schema is present but extremely sparse: only one parameter 'query_payload' (string type, minimal description). No output schema is documented, the tool returns a generic success message with no structured fields. No error handling guidance, no parameter constraints, no indication of what 'query_payload' should contain or how to construct it. The tool name uses a generic verb ('execute') rather than a domain-specific action verb. No indication of idempotency, side effects, or prerequisites. This server appears to be a stub implementation rather than a production-ready tool.

• Rename tool to a domain-specific action verb. E.g., 'synthesize_merchant_reviews', 'generate_review_citations', or 'fetch_verified_reviews', something that conveys the actual business function.
• Document the output schema explicitly. Define all fields returned (e.g., review_synthesis_id, consensus_sentiment_score, pros_highlights, cons_drawbacks, grounded_citations, synthesis_report_url) with types and descriptions.
• Expand the input parameter description to 100-200 chars. Explain what query_payload should contain (e.g., 'JSON object with product_query and min_verified_reviews_count'), provide format constraints, and give a concrete example.
• Add error handling responses. Define what happens if the skill fails, the payload is malformed, or the product query is not found. Return actionable error messages with recovery steps.
• Add tool annotations (readOnlyHint, idempotentHint) to clarify whether the tool modifies state and whether it is safe to retry.
