Move the agent-spine bundle and the stdio/ACP/JSON-RPC app packages out of core/ and ui/ into a new packages/examples/ group, renamed with a -demo suffix so the npm name marks them as non-product surface: core/agent-core -> examples/agent-spine-demo (dsh-agent-spine-demo) ui/stdio-agent -> examples/stdio-demo (dsh-stdio-demo) ui/acp-agent -> examples/acp-demo (dsh-acp-demo) ui/jsonrpc-agent -> examples/jsonrpc-demo (dsh-jsonrpc-demo) Update every code/config/test reference and reference-only doc mentions, and regenerate module-graph, config-catalog, and doc-graphs. The jsonrpc bin (dsh-jsonrpc-agent) and single-file exe (dsh-jsonrpc-agent-pkg) keep their names; the SDK runtime-startup surface is reconciled separately.
subagent/ — subagent capability family
The subagent seam: an agent delegating work to a child agent. Like the bash and llm families this is a capability seam (see capability seams) — but with one defining difference: multiple provider implementations coexist in one context, registered by name, rather than the single-implementation bash shape. The registry mirrors the LLM adapter registry.
| Package | Role | ctx key |
|---|---|---|
subagent/ |
Abstract subagent seam: named-provider registry + vocabulary | ctx.subagents |
subagent-inprocess/ |
Shared in-process run driver (no provider; one cleanup effect per run) | — |
subagent-spawn/ |
In-process backend: a fresh child agent | (registers on ctx.subagents) |
subagent-fork/ |
In-process backend: a child seeded with the parent's completed-turn prefix | (registers on ctx.subagents) |
subagent-subprocess/ |
Shared out-of-process machinery: env scrub, dispose ladder, isolated config dirs (pure lib; registers nothing) | — |
subagent-acp/ |
Out-of-process backend: a child agent in a spawned subprocess, driven over ACP | (registers on ctx.subagents) |
tool-subagent/ |
Model-facing subagent delegation tool over ctx.subagents |
(registers on ctx.tools) |
The interface lives at subagent/subagent/. The in-process subagent-spawn / subagent-fork backends share the subagent-inprocess driver (a library with no provider of its own — both depend on it, neither on the other), the out-of-process subagent-acp backend builds on the subagent-subprocess library (the credential env scrub, the dispose ladder, isolated config dirs) and ships alongside them here; the test-only dsh-subagent-mock (in support) is separate. All product packages except the mock.
