Struct SubagentResult 

pub struct SubagentResult {
    pub status: Option<String>,
    pub prompt: Option<String>,
    pub agent_id: Option<String>,
    pub agent_type: Option<String>,
    pub content: Vec<ContentBlock>,
    pub resolved_model: Option<String>,
    pub total_duration_ms: Option<u64>,
    pub total_tokens: Option<u64>,
    pub total_tool_use_count: Option<u64>,
    pub usage: Option<UsageInfo>,
    pub tool_stats: Option<SubagentToolStats>,
}

Token, timing, and tool-use accounting for a completed subagent (Task) run.

The Claude CLI echoes this object in the tool_use_result of a Task tool’s result message. It is the typed source of truth for subagent token attribution: the per-run total_tokens, total_duration_ms, and total_tool_use_count correspond to the subagent_tokens / duration_ms / tool_uses line items the CLI renders in its human-readable <usage> block, and usage carries the full per-model token breakdown for the run.

Fields

status: Option<String>

Completion status of the subagent run (e.g. "completed").

prompt: Option<String>

The prompt the subagent was launched with.

agent_id: Option<String>

Stable identifier of the spawned subagent.

agent_type: Option<String>

Subagent type that ran (e.g. general-purpose, Explore).

content: Vec<ContentBlock>

Final content blocks the subagent returned.

resolved_model: Option<String>

Model the subagent actually resolved to (e.g. claude-sonnet-4-6).

total_duration_ms: Option<u64>

Wall-clock duration of the subagent run, in milliseconds.

total_tokens: Option<u64>

Total tokens consumed by the subagent — the subagent_tokens rollup line.

total_tool_use_count: Option<u64>

Number of tool invocations the subagent made.

usage: Option<UsageInfo>

Detailed token / cache usage for the subagent run.

tool_stats: Option<SubagentToolStats>

Per-category tool-use counts, present for some agent types (e.g. Explore).
