 `agent-loop` is the one concrete implementation of the `agent` seam and lives here because it is the harness's default product loop; everything else in `core/` is interface/vocabulary. Plugins depend on the `agent` vocabulary, never on `agent-loop` directly, so the loop stays swappable.

+# examples/ — ready-to-run demo bundles
+
+Pre-composed plugin bundles a thin leaf `cordis.yml` loads instead of assembling the spine and a front door by hand. These are **demo / reference** packages — the `-demo` npm suffix marks each one as non-product surface, readable straight off the package name. The runnable leaves under the repo-root [`examples/`](../../examples/AGENTS.md) and the [Python SDK runtime](../../python/sdk-runtime/README.md) are the consumers; each is just its swappable backends plus one bundle entry.
+
+| Package | npm name | Role |
+|---|---|---|
+| `agent-spine-demo/` | `@deepseek-ai/dsh-agent-spine-demo` | The executor-less/UI-less agent spine as one bundle plugin (`timer` + `llm` + sessions + system-prompt + tools + skills + agents + invariants + `tool-bash` + `tool-skill` + `agent-loop`) |
+| `stdio-demo/` | `@deepseek-ai/dsh-stdio-demo` | Terminal stdio chat app: the spine + console logger + readline UI + a pre-created `main` agent, with a boot `bin` |
+| `acp-demo/` | `@deepseek-ai/dsh-acp-demo` | ACP server app: the spine + JSONL persistence + the [`acp`](../ui/acp/README.md) bridge (no stdout logger), with a boot `bin` |
+| `jsonrpc-demo/` | `@deepseek-ai/dsh-jsonrpc-demo` | Bin-only runtime that boots an external `cordis.yml` for the stdio JSON-RPC SDK client |
+
+`agent-spine-demo` is the shared bundle; `stdio-demo` and `acp-demo` compose it with opposite front-door clusters (console logger + readline UI vs the stdout-owning ACP bridge) and own their boot bins. `jsonrpc-demo` mounts no composition of its own — it boots whatever tree the deployment's `cordis.yml` names, and is what the Python SDK runtime launches.
+
+These are **not** product API. The spine pieces they bundle live in [`core/`](../core/README.md), the bridges/channels/boot-glue in [`ui/`](../ui/README.md), and the swappable backends (LLM adapter, bash executor) in their capability groups; a demo bundle just picks one concrete composition of them. Swap or fork one freely.
+
+Do not confuse this group with the repo-root [`examples/`](../../examples/AGENTS.md): that directory holds the runnable `cordis.yml` **leaves**; this group holds the **bundles** those leaves load.
+
+## The jsonrpc bin/exe names are legacy
+
+`jsonrpc-demo` renamed like its siblings, but its bin is still `dsh-jsonrpc-agent` and the single-file executable is still `dsh-jsonrpc-agent-pkg` (referenced across the [Python distribution](../../python/sdk-runtime/README.md)). Those names are the SDK's runtime-startup surface; they are reconciled when the SDK unifies that startup flow, not by this move.

 Because the package wires no logger entry, an ACP leaf has **nothing to get wrong by default**: it only picks backends, so the common mistake — copying a console-logger entry from the stdio config — has no place here. (A leaf author technically *can* still add `@cordisjs/plugin-logger-console` as a sibling entry; the package can't forbid that. So the rule stands: never add a stdout logger to an ACP leaf — stdout is the JSON-RPC channel. Use a stderr exporter if you need logs.)

 - **non-local skill providers** — the bundle ships the skill registry, the local filesystem provider, and the `skill` tool; deployments can add other providers such as embedded or remote catalogs as siblings.

 A UI integration is a client-driver plugin, not a loop change and not a capability seam: it consumes the existing `agent/*` event taxonomy and the `dsh-agent` factory. The `jsonrpc` plugin is the SDK-client sibling of the `acp` bridge (a JSON-RPC server over `ctx.agents` for out-of-process SDK clients rather than editors).

 `user-approval`, `user-interaction`, and `tool-ask-user` live here because asking a human is a UI-backed product affordance, not part of the providerless core spine. `user-approval` owns the one-shot `ctx.approval` decision mechanism and its policy tier; answerers remain with their UI channel owners. `user-interaction` remains provider-neutral (`ctx.userInteraction`), while `tool-ask-user` is its model-facing consumer and the app/bridge packages provide concrete providers.
