@irisrun/subagents

Durable, replayable delegation. When an agent delegates a sub-task, the child runs in its own durable session and journal; the child's final output is recorded in the parent as the delegating effect's result — so the parent replays deterministically without ever re-running the child, while the child replays independently.

What it is

Wires the subagent effect kind via a host-side performer. makeSubagentPerformer answers a delegation effect by driving a child agent to completion (driveToCompletion, bounded by DEFAULT_MAX_TURNS) and journaling its result in the parent. Pure breadth on the existing journaled substrate — depends on @irisrun/core + @irisrun/host only, no kernel change.

Use it

Register makeSubagentPerformer as the host's subagent performer (the CLI wires it from a project's subagents.json).

See docs/Audit & reproducible evals for delegation on the journaled substrate.
