Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
carbone-skill
Official Carbone skill — complete templating language reference covering tags, loops, conditions, formatters, aggregators, and all output formats (DOCX, XLSX, PPTX, ODT, HTML, Markdown, PDF)
RTL Email
Send email in right-to-left scripts (Hebrew, Arabic, Farsi, Urdu) that actually renders RTL. Plain-text email carries no direction metadata, so RTL bodies render LTR in many clients and multi-part numbers like account references reorder. Ships dir=rtl HTML templates, separate personal and business send skills inheriting saved signature profiles, and one-time signature setup. Works with Google Workspace MCP or Resend.
