json2pptx

Generate consulting-quality PowerPoint decks from user prompts using json2pptx. Applies constrained generation: 4-phase workflow (Plan → Vary → Render → Repair), pattern-based shape grids, accent strategy, deck-rhythm analysis, invariant enforcement, and validate-repair loop. Use when the user asks to create, generate, or build a presentation or slide deck.

Visually inspect slide images for layout, spacing, contrast, overflow, and rendering issues. Use when spawning a Haiku subagent to QA presentation slides that have already been converted to images. Trigger whenever slide images exist and need to be checked before declaring a presentation complete.

Render and validate standalone SVG/PNG charts and diagrams via the svggen-mcp server. Use when the user wants a single chart/diagram artifact (SVG markup or PNG bytes) without generating a full PowerPoint deck. For embedding the rendered SVG inside a deck slide (shape_grid icon.svg_data), see ../generate-deck/SKILL.md.
