Tools of Flowboard
	Description		Read-only	Idempotent	Open world
`create_diagram`Create one persistent Flowboard architecture diagram after calling list_shapes and list_diagrams, then reuse its ID with patch_diagram or update_diagram instead of making test copies. Any node may contain any other node; indentation expresses grouping, not infrastructure policy. Markdown nodes look like '- API {#api type=pod x=100 y=100}'. Flows belong under ## Flows. JSON and YAML use flows[]. A node may use icon=github independently of type.

`list_shapes`Discover every Flowboard node shape before drawing. Search all core, AWS, and Google Cloud shapes by type, label, detail, provider, or category.

`patch_diagram`Safely edit an existing diagram without replacing the full document. Operations run as one atomic saved update.

`validate_diagram`Check broken flows, missing/cyclic parents, children outside parent bounds, overlapping sibling or top-level nodes, pipelines crossing unrelated resources, orphaned nodes, and optional company policy rules. Layout findings include exact coordinates and a patch_diagram-compatible suggested_fix so an agent can correct placement without asking a person which direction to move something. Rerun validation after applying fixes. Returns findings without changing the diagram; mutation responses include findings and computed_bounds.
