Shipping Cost is a production-ready Claude Code skill (quality score 70/100) in the tools-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/shipping-cost/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when you need to compare UPS/FedEx/USPS/DHL rates, analyze zone-skip and zone-reduction opportunities, find parcel-to-LTL and LTL-to-FTL modal break points, audit accessorial surcharges (fuel, residential, DAS, DIM weight), evaluate carrier contract negotiation leverage, benchmark lane rates against market, optimize multi-origin fulfillment, or quantify invoice audit recovery. Produces a prioritized savings waterfall with dollar estimates.
