Used with Carbone MCP

The Carbone Skill pairs with the Carbone MCP server. The skill gives the AI assistant deep knowledge of Carbone's templating syntax, while the MCP server provides direct API access to render documents. Together, they let you design templates and generate documents in a single conversation: the skill handles syntax correctness, the MCP handles API actions.

What the skill covers

• Tag syntax: {d.}, {c.}, aliases, i18n, runtime options
• Formatters: date, number, string, currency, and chaining
• Conditions: showBegin/showEnd, hideBegin/hideEnd, ternary expressions
• Loops: arrays, nested loops, aggregation, drop-row patterns
• :set patterns for computed and conditional values
• HTML templates: CSS injection, charts, headers/footers, PDF options
• Markdown templates: loops in tables, converting to DOCX/PDF
• Embedding Carbone tags into AI-generated DOCX, XLSX, and PPTX files
• Best practices and a validation checklist
• Template formats: XML HTML ODT ODS ODP DOCX XLSX PPTX ODG SVG MD IDML — and PDF form templates
• Export formats: PDF DOCX XLSX PPTX ODT ODS ODP HTML CSV TXT JPG PNG GIF SVG WEBP EPUB MD RTF (160+ conversions)
