# Generate Flowcharts

Flowcharts turn complex processes into something anyone can follow. Approval workflows, user onboarding flows, error handling logic, deployment pipelines -- these are all easier to understand as a visual flow than as a wall of text or a nested list of steps.

The generate_diagram skill creates flowcharts from plain-text descriptions of your process. Describe the steps, decisions, and branches, and the AI produces a properly structured flowchart with standard shapes -- rectangles for actions, diamonds for decisions, and arrows showing the flow direction. It handles parallel paths, loops, and exception flows without manual layout.

Product managers use flowcharts to document business processes. Engineers use them to visualize complex conditional logic before implementing it. Support teams use them to create troubleshooting guides. Operations teams use them to document incident response procedures. In every case, the flowchart communicates the process faster and more clearly than prose.
