Struct NodeDefinition 

pub struct NodeDefinition {
    pub node_type: String,
    pub label: String,
    pub icon: String,
    pub header_color: String,
    pub category: String,
    pub fields: Vec<FieldDef>,
    pub inputs: Vec<Port>,
    pub outputs: Vec<Port>,
}

Declarative definition of a node type.

Registered via WorkflowGraph.registerNodeType(). The renderer uses this to draw colored headers, inline fields, and type-specific visuals. Consumers can define any number of custom node types.

Fields

node_type: String

Unique type key (e.g., “agent”, “tool”, “my-custom-node”). Matched against Job.metadata["node_type"].

label: String

Display label shown in the header bar.

icon: String

Icon character (emoji or Unicode) rendered in the header.

header_color: String

Hex color for the header bar (e.g., “#3b82f6”).

category: String

Category for grouping in palettes (consumer-defined, no constraints).

fields: Vec<FieldDef>

Inline fields rendered in the node body.

inputs: Vec<Port>

Default input ports for this node type.

outputs: Vec<Port>

Default output ports for this node type.
