FlowCanvas

21 tools in this family (folder Editor/Tools/FlowCanvas/ in the bridge package). Effect: writes changes the project or the scene, read-only does not, destructive deletes or overwrites and the client asks before running it.

Tool	Effect	Description
flow_graph_add_blackboard_variable	writes	Declare a variable on a graph's blackboard. Scope is one of Local, Global, Blackboard. Type is
flow_graph_add_node	writes	Add a node to a FlowScript graph. Kind must be one of Event, Action, Function, Variable,
flow_graph_connect_ports	writes	Wire two ports together. Buril enforces flow-to-flow and data-to-data — mixing kinds is rejected.
flow_graph_create_graph	writes	Create a new FlowScript graph. The graph starts in Draft state and is persisted to the mock
flow_graph_create_macro	writes	Promote a graph into a reusable macro. Buril auto-derives macro ports from nodes whose type
flow_graph_detect_cycles	read-only	Cycle-detection-only pass over the graph's flow edges. Returns each cycle as a node-id chain.
flow_graph_disconnect_ports	writes	Remove a wire by connection id.
flow_graph_emit_blackboard_accessor	writes	Generate a strongly-typed MonoBehaviour that exposes each variable on a graph's blackboard as a
flow_graph_emit_custom_flownode	writes	Generate a custom FlowNode subclass (C# source) ready to drop into the project's Scripts folder.
flow_graph_emit_macro_export	writes	Generate an editor-only static class that exports a graph as a reusable macro asset,
flow_graph_emit_nodecanvas_migration	writes	Generate the NodeCanvas → FlowCanvas migration helper: a static class with a menu item that
flow_graph_export_graph_json	read-only	Dump the whole graph (header + nodes + connections + blackboard + event handlers) as JSON.
flow_graph_init	read-only	Probe the project for an installed FlowCanvas (Paradox Notion) asset and report what was found.
flow_graph_list_graphs	read-only	List every FlowScript graph the mock store knows about. Optional tag filter narrows results
flow_graph_list_nodes	read-only	Return every node + port descriptor in a graph. Optionally include connections by setting
flow_graph_open_graph	writes	Open an existing FlowScript graph by id. Marks the graph as Editing so subsequent mutations are
flow_graph_register_event_handler	writes	Register a handler for a named event on a FlowScript graph. The handler is later invoked by
flow_graph_remove_node	writes	Remove a node from a graph. Cascades — every connection touching the node is also dropped.
flow_graph_save_graph	writes	Persist the graph header — recalculates cached node/connection/variable counts and flushes the
flow_graph_set_blackboard_value	writes	Update the stored value of an existing blackboard variable. Looks up the variable by name and
flow_graph_validate_graph	read-only	Run the full Buril FlowCanvas validator on a graph: structural integrity, port references,
