What deckset does

This skill supplies syntax references for generating slide decks in Deckset using Markdown. It guides the model through app-specific tags. These include [fit] for scaling headings alongside [.use-source-list-numbering] to preserve manual list orders.

Technical presentations benefit from the [.code-highlight] directives. The agent can mark single lines, ranges, or multi-step animations across presentation clicks. Note that custom code background styling cannot be set via Markdown yet and must be handled in the Deckset theme UI.

What it helps with

  • format step-by-step code line highlights for slide transitions
  • scale large titles across slide widths using fit markers
  • preserve custom numbering schemes in ordered lists
  • create slide-to-slide navigation links with HTML anchors

Example prompts for the agent

  • Format this code snippet with a step highlight starting at line 2 and moving to lines 6-8.
  • Create a title slide using fit tags so the header stretches across the canvas.
  • Add a 3-column comparison table with center-aligned text for a Deckset presentation.
