Replace the TypeScript SDK's public arbitrary command/argv launch surface with the same-version dsh CLI, a named profile, ordered per-launch patches, optional process cwd, and explicit Harness home selection. Installed consumers use the built CLI; clean source checkouts use the package's src/bin.ts through an absolute tsx/esm loader and a source-only patch that omits build-generated Typert loading. Materialize explicit or inherited environments at spawn time, keep profile-internal patches below caller patches, and resolve every caller-relative path before the child starts. The SDK subagent provider validates its optional CLI and patch files at plugin load and requires an isolated absolute child home. Treat JSON-RPC initialize as the Loader-owned readiness point: Loader settlement joins entry imports, fiber lifecycle work, and synchronous effect registration, so the server needs no scheduler tick. A delayed profile entry registers a private adapter before initialize resolves, proving caller-supplied plugin routes are visible without fallback. Update sdk-app ownership, server diagnostics, TypeScript SDK examples, nested-loader coverage, and session-upload replay layering together. The following commit contains only the regenerated SDK transcripts, keeping this API and lifecycle change directly reviewable.
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-in-process/ |
Starts a fresh in-process child | registers on ctx.subagents |
subagent-fork-in-process/ |
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 |
The Codex and Claude Code packages are independent optional Profile Bundles. Install either or both with dsh plugin --profile <name> add @deepseek-ai/dsh-subagent-codex @deepseek-ai/dsh-subagent-claude-code, then restart that Profile; each package registers only its dormant Host provider. To grant a tool, copy a complete Agent Preset, remove disabled from each matching tool row, and start a new Session. Removing one package withdraws only that provider and its private runtime closure on the next Profile start.
