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 also independent 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 installed package registers only its own dormant Host provider. Full Agent Presets keep separate disabled tool templates, so installation alone exposes no model tool. Removing one package withdraws only that provider on the next Profile start.

See the decisions for the capability family, continuable children, and control tools.

The subsystem reference — start requests, results, live runs, the provider contract, continuable background children — is docs/subsystems/subagent.md; design rationale in the subagent capability seam, continuable background subagents, and merged subagent control service Agent Notes.
