## What it does
The skill breaks a process into steps, finds the decision points and lays out the diagram as HTML with inline SVG. It ships ready-made shapes: rounded rectangles for start and end, plain rectangles for steps, diamonds for decisions, arrows with labels on each branch. Swimlanes are there too, for processes that cross roles or systems.
Styling runs on classes — `.start-end`, `.process`, `.decision` — and the colours are fixed at green, blue and orange, so matching your own palette means editing the file by hand. Output lands in `[process]-flowchart.html`.
The result is a static SVG picture. No dragging nodes around, no live editing. If you want a diagram editor, look elsewhere. What you do get is a file that opens in a browser with no build step and no dependencies.
