cocoindex-diagrams

This skill should be used when creating, editing, or reviewing inline SVG diagrams for the CocoIndex docs site (anything under docs/src/content/docs/**). It encodes the component-based primitive system under docs/src/components/diagrams/, the palette + shape semantics, the preview-and-verify loop using headless Chrome with the /docs base path, and the pitfalls that cost iterations to discover. Trigger phrases include "add a diagram to the docs", "edit this diagram", "replace the SVG in core_concepts", "make a diagram for processing_component", "check how the diagram looks".
