Capabilities

Tools 2

create_flowchart

Turn Mermaid flowchart or graph syntax, or an indented outline, into FlowSimp links. Use it when the steps already exist as text and someone needs a diagram they can view or edit. Returns JSON with shareUrl (a read-only /view# link), editUrl (opens the editor at /?board=), nodeCount, and connectionCount. An optional title is echoed in that JSON; it is not drawn on a shape. The diagram is compressed into the link, so nothing is stored and the call does not write to a database. Only flowchart and graph syntax are accepted. Other Mermaid types are refused. Text is limited to 16,000 characters and about 80 shapes.

Discovered
list_templates

List every built-in FlowSimp template. Use it when a starter diagram is a better fit than generating one from text. Takes no arguments. Returns JSON with a templates array of id, label, and editUrl. The ids are swimlane, decision-tree, user-flow, org-chart, flowchart, process, network, mind-map, data-flow, algorithm, bpmn, onboarding, and approval. Each editUrl opens that template in the editor. The list is fixed, and the call does not store or change anything.
