Struct SubagentStats 

pub struct SubagentStats {
    pub spawned: u64,
    pub requested: SubagentSpawnRequests,
    pub started_in_background: u64,
    pub by_type: BTreeMap<String, u64>,
    pub max_depth: u64,
    pub spawned_by_subagents: u64,
    pub completed: u64,
    pub failed: u64,
    pub killed: SubagentKillCounts,
    pub refused: SubagentRefusalCounts,
}

Running totals for subagents started through the Agent tool, carried on result frames (CLI 2.1.239+) as ResultMessage::subagent_stats.

Cumulative for the session: a resumed session starts fresh, and a mid-session /clear zeroes it — though a background subagent that outlives the /clear still records its outcome, so completed, failed, and killed can then exceed spawned. Forked skills, workflows, teammates, and other internal agents are not counted.

Fields

spawned: u64

Subagents actually started; a refused or failed launch is not counted.

requested: SubagentSpawnRequests

Spawns by the run_in_background value the model passed; all count as unset while the parameter is not offered.

started_in_background: u64

Spawns that started in the background after defaults and session settings; the rest blocked the spawning tool call.

by_type: BTreeMap<String, u64>

Spawns by agent type.

max_depth: u64

Deepest spawn: 1 = started by the main thread, 2 = by a depth-1 subagent.

spawned_by_subagents: u64

Spawns made from inside another subagent (depth > 1).

completed: u64

failed: u64

killed: SubagentKillCounts

Subagents stopped before finishing, by who stopped them.

refused: SubagentRefusalCounts

Agent tool calls turned down because a limit was reached (other denials, such as an unknown agent type, are not counted).
