Calculates optimal tiered bulk discounts to maximize wholesale profit margins
Single tool 'optimize' has moderate naming clarity but significant gaps in description depth and parameter documentation. The tool schema IS visible and properly typed, but descriptions are minimal and lack LLM-optimized guidance. Parameter descriptions are present but brief (10-25 chars each). No output schema is documented. No error handling guidance for invalid inputs or edge cases. The tool performs a pure calculation (read-only), but the description does not state this explicitly, nor does it explain when to use it vs. alternatives or what prerequisites exist.
Calculates optimal tiered bulk discounts to maximize wholesale profit margins
Tool description is too brief (97 chars) and lacks LLM-optimized guidance. Does not explain WHEN to use this tool (e.g., during pricing strategy planning), WHAT it returns structurally, or dependency hints (e.g., 'Call this to model tiered discounts before implementing'). Current description jumps straight to mechanics without context.
Parameter descriptions are extremely brief and lack actionable constraints. 'The base unit price' (20 chars) and 'The cost per unit' (17 chars) lack format guidance (e.g., '$ amount, must be ≥ 0, typically USD'). 'Maximum discount percentage' (28 chars) does not explain the default (25.0) or why it exists. No mention of valid ranges (e.g., 0 - 100, or 0 < unit_cost < unit_price). LLMs cannot infer these from bare names.
Output schema is NOT documented. Callers (LLMs, agents) cannot plan downstream operations without knowing what fields to expect. The source code shows the tool returns a dict with 'base_unit_price', 'unit_cost', 'tiers' (array of objects with 'min_quantity', 'discount_percentage', 'price_per_unit', 'margin_per_unit_usd', 'margin_percentage'), and 'average_order_value_uplift_est', but this structure is nowhere in the MCP tool registration or docstring.

No error handling or validation guidance. The tool has internal logic (e.g., 'Preserve at least 5% margin') that could fail silently or produce unexpected outputs (e.g., if unit_cost ≥ unit_price). No docstring explains what happens if inputs are invalid, negative, or zero. The 'max_discount' could be reduced to preserve margin, but this is not documented, leaving LLMs guessing about actual discount delivered.
Tool name 'optimize' is generic and does not start with a clear action verb. 'optimize' could mean optimize price, margin, conversion, speed, etc. Better names: 'calculate_tiered_discounts' or 'generate_bulk_pricing_tiers'. This follows verb_noun convention and clarifies intent immediately without reading the description.
