Struct ProgressEvent 

pub struct ProgressEvent {
    pub metadata: EventMetadata,
    pub tool_use_id: Option<String>,
    pub parent_tool_use_id: Option<String>,
    pub data: ProgressData,
}

Progress event wrapper

Contains real-time progress updates during tool execution.

Links

• tool_use_id: Links to ToolUseBlock.id that triggered this progress
• parent_tool_use_id: For nested tool invocations (agents spawning agents)
• metadata.parent_uuid: Links to parent message in conversation

Frequency

~82,200 occurrences per large session (MOST FREQUENT event type!)

Fields

Links to ToolUseBlock.id in assistant message

parent_tool_use_id: Option<String>

Parent tool use ID (for nested tools)

Used when agents spawn sub-agents or tools invoke other tools

data: ProgressData
