One assistant message carrying several subagent calls now overlaps them under the rolling pool (maxParallelToolCalls) instead of serializing each foreground delegation behind an exclusive barrier; results still commit in model order. tool-subagent declares isConcurrencySafe: () => true for every call form: children work in their own sessions, a run never mutates the parent session, and sibling workspace coordination already belongs to the model for background, continuable, and workflow children. The former serial-execution pin flips to a parallel pin plus a gated genuine-overlap test, and the authored subagent-parallel snapshot pins the assembled transcript (tool/call, tool/call, tool/result, tool/result) with interchangeable twin children, which replay race-free under the existing first-call binding and createdAt harvest ordering. The provider seam now requires concurrent starts and continuable preparations for distinct children to isolate operation-local state, cancellation, settlement, and cleanup; a continuable gate test proves a cancelled preparation leaves no Agent or durable Session while its sibling persists independently.

subagent/ — subagent capability family
English | 中文
This family lets an agent delegate work to child agents. Multiple named providers may coexist in one context.
| Package | Role | ctx key |
|---|---|---|
subagent/ |
Defines provider registration, delegation, and continuation | ctx.subagents |
subagent-inprocess/ |
Provides the shared in-process run driver | — |
subagent-spawn/ |
Starts a fresh in-process child | registers on ctx.subagents |
subagent-fork/ |
Starts an in-process child from the parent's completed history | registers on ctx.subagents |
subagent-acp/ |
Starts an out-of-process child over ACP | registers on ctx.subagents |
subagent-codex/ |
Starts a real Codex app-server child | registers on ctx.subagents |
subagent-claude-code/ |
Starts a real Claude Code child through the official Claude Agent SDK | registers on ctx.subagents |
subagent-dsh-sdk/ |
Starts an out-of-process Harness child through the TypeScript SDK | registers on ctx.subagents |
tool-subagent/ |
Exposes delegation to the model | registers on ctx.tools |
tool-subagent-control/ |
Exposes child messaging and listing to the model | registers on ctx.tools |
tool-subagent-report/ |
Provides the child-to-parent report channel | registers in child scopes |
