Feishu Cli Board

This gives Claude five different ways to draw diagrams in Feishu whiteboards, from standard flowcharts to completely custom SVG illustrations. Path A uses Mermaid server-side rendering for quick charts. Path B uses a local engine when you hit server limits. Path C is the standout: it converts arbitrary SVG into native Feishu nodes, so every rectangle, circle, and text element becomes individually editable. The docs include a 14-diagram reference (flywheels, fishbones, dashboards, subway maps, even cyberpunk cityscapes) and a five-step pipeline script that handles z-index bugs and batch uploads automatically. Path D imports simple SVG as a single decoration node, and Path E lets you hand-code precise layouts with absolute coordinates. Works with app tokens, no manual auth needed.
