International ecommerce plans often begin with a country ranking and end with a shipping recommendation. That leaves the expensive questions unresolved: whether the product can be sold as described, who carries the seller and importer obligations, what each order contributes after every cross-border cost, and what happens when delivery, returns, payments, or tax reconciliation fail.
Cross-Border Ecommerce Expansion builds the decision record before inventory and ad spend move. It binds one destination and product family to current sources, separates observed facts from reported claims and missing inputs, and turns customer price into a signed landed contribution-margin bridge. Tax, customs, product compliance, consumer rights, payments, privacy, fulfillment, returns, support, and localization stay as owner-bound gates. Unknowns do not become neutral scores or remembered rates.
Use it to screen a market, validate one entry, compare direct shipping with destination fulfillment or a local partner, design a capped pilot, or stop a weak rollout. The handoff includes evidence coverage, economics scenarios, operating-model tradeoffs, start gates, stop conditions, reconciliation, rollback, owners, and a conservative verdict. Proposed, approved, launched, verified, and scale-ready remain separate states.
Version 1.0.0 was reviewed on 2026-07-17 and evaluated through Codex CLI with gpt-5.6-sol in 12 fresh read-only contexts. The candidate scored 100 across three cases, compared with 85 for the same agent without the skill and 86.67 for the exact free upstream. It led the upstream by 5 points on an incomplete UK skincare entry, 11.25 points on a failed Germany pilot, and 23.75 points on the canonical machine-checkable handoff. All cases passed. The evaluation covers those supplied cases. It does not prove product admissibility, tax or customs treatment, customer demand, provider terms, contribution margin, or launch approval for a real market.
