What problem does it solve? Turning a Mermaid diagram into a branded, editable PowerPoint slide normally means hand-placing shapes and connectors, losing the template's fonts and colours, and shipping decks with clipped diagrams or leftover placeholder text. This Skill drives officecli to render Mermaid natively into the MFEC template, then annotates, animates, and verifies the result. ## Core Features & Use Cases - Native Mermaid rendering: Inserts flowcharts and sequence diagrams as real editable PowerPoint shapes and connectors inside the MFEC branded template, with an image-render fallback for other Mermaid types. - Role-based annotation: The bundled annotate.py colours nodes by category, adds unboxed captions, and draws a legend, while flow-motion.py animates a marker travelling between nodes since PowerPoint cannot animate shapes inside a group. - Layout verification: check-layout.py catches off-slide diagrams, overlapping shapes, in-diagram label collisions, and text boxes that silently grow past the slide edge — failures that officecli's own issue report cannot see. - Use Case: An engineer needs to present a Kafka versus RabbitMQ architecture decision. The Skill clones the template's diagram slide, renders the flowchart, colours streams and tables by role with a legend, animates a packet along the route, and adds the comparison table and takeaway slides around it. ## Quick Start Ask the agent to turn your Mermaid flowchart into an editable slide in an MFEC-branded PowerPoint deck, with nodes colour-coded by role and a legend.
