Turn a cost model into a customer-facing weight-banded price table. PREMIUM (license). Prices each band at its upper bound so you never under-charge inside a band, then rounds up to a tidy increment. Typical input {"base_cost": 4.2, "cost_per_lb": 0.65, "bands_lb": [1, 2, 5, 10], "margin_pct": 25} returns {"bands": [{"up_to_lb": 1, "cost": 4.85, "price": 6.5}, ...], "over_top_band": "quote individually"}. Use when publishing shipping prices customers pay. Not for the cut-off at which shipping becomes free — that is free_shipping_threshold. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "bands_lb must contain at least one upper bound"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
