Single tool with minimal definition quality. Tool name 'execute_skill_action' is generic and does not follow verb_noun pattern clearly (execute_skill_action vs. optimize_price or calculate_elasticity). Description is present (89 chars) but lacks actionable context: does not explain WHEN to use it, what it returns, or how it differs from other tools. Input schema exists but is severely underdeveloped: single string parameter 'query_payload' with minimal description ('Input execution payload for this skill') provides no guidance on format, structure, or valid values. No output schema documented, LLM cannot predict response structure. No error handling guidance. Tool appears to be a pass-through wrapper with no real validation or structured behavior.

• Rename tool to 'optimize_price_elasticity' or 'calculate_elasticity_impact' to match verb_noun pattern and convey specific action.
• Replace 'query_payload' string parameter with structured input: define required fields (sku_id, current_price, cogs_cost, competitor_price, margin_floor) with types, descriptions, and constraints (e.g., price > 0, margin 0-1).
• Document output schema explicitly: return object with fields (pricing_optimization_id, sku_id, recommended_price_usd, projected_margin_pct, projected_sales_lift_pct, projected_profit_lift_pct, simulation_url) and their types.
• Expand tool description to 100-150 chars: 'Optimize product pricing based on elasticity analysis. Accepts SKU, current price, cost, competitor price, and margin floor. Returns recommended price, projected margin, and sales/profit lift percentages. Use when adjusting retail prices to maximize profit while staying competitive.'
• Add error handling: return structured errors with category (invalid_input, missing_sku, calculation_failed) and recovery guidance (e.g., 'Invalid margin_floor: must be 0-1. Try 0.45 for 45% target.').
