KISS review: two behavior issues to fix before merge.

1. The skill allows “top items by estimated weekly revenue” as a fast-growth rule, but revenue alone is not growth and can surface old/high-ticket slow movers as “taking off.” Please require a real momentum proxy, e.g. low time on air + strong estimated weekly sales/revenue.
2. The skill tells agents to hand off to the “single-category international skill” and international-product-matcher, but those skills are not present in this PR. Please remove those handoffs or add the actual skills/names in this PR.

Review — fast-growing-international-products

Summary: A marketwide skill that uses JoomPulse to surface fast-growing international/imported products across all Mercado Livre (Brasil) categories, returned as one markdown table with a Category column plus price, est. weekly sales/revenue, rating, time-on-air, logistics, listing type, and seller medal, with the estimate disclaimer and optional cards/charts.

Findings:

• major — Dangling references to two non-existent sibling skills ("single-category international skill", "international-product-matcher skill"). The agent is instructed to hand off to skills that aren't installed. Add the siblings or soften the references.
• major — "JoomPro" is named as the import target ("match items to a specific JoomPro product for import"). JoomPro is a separate Joom B2B venture and appears nowhere else in this public catalog; the PR's own public-safety checklist claims "no private service names." Please confirm this is cleared for public exposure, or remove/genericize it.
• minor — "Fast growth" is left entirely to the agent ("there is no single fast-growth flag... define it pragmatically"), so two runs can produce very different lists. Consider a recommended default rule for reproducibility.
• nit — Frontmatter description is long and front-loads ALL-CAPS emphasis; trimming the cross-skill handoff text would tighten triggering.
• nit — Disclaimer is pt-BR only, while ml-product-analysis ships a bilingual EN/pt-BR disclaimer; an English-speaking seller would get a Portuguese disclaimer.

No broken queries, credentials, internal paths, or write operations; read-only and discovery is convention-based (no manifest change needed). Blockers are the first two findings.
