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.

echo-agent
Runnable demo: stdin chat with a scripted mock model and an echo tool. The all-mock skeleton — "swap the backend, keep the app".
What it shows
This example is just a leaf cordis.yml: it loads the @deepseek-ai/dsh-stdio-demo app (which bundles the whole @deepseek-ai/dsh-agent-spine-demo spine, the console logger, JSONL persistence, the readline UI, and a pre-created main agent), and swaps in two example-local backends plus hmr:
mock-llm.ts— a mockLlmAdapterthat streams scripted responses and calls theechotool when the user types "echo ". Registered withctx.llm.registerAdapter(['mock-echo'], …).echo-tool.ts— a tool registered viactx.tools.register(defineTool(…))with typedexecuteargs; echoes text back uppercased.
Swapping mock-llm for the real llm-deepseek adapter is all that separates this from coding-agent — the same app, a different backend.
Plugin files
| File | Role | Key patterns demonstrated |
|---|---|---|
src/mock-llm.ts |
LlmAdapter registration |
ctx.llm.registerAdapter(['mock-echo'], …), streaming chunks with the proper block-start/block-end protocol |
src/echo-tool.ts |
Tool registration | ctx.tools.register(defineTool(…)) with typed execute args, returning ContentBlock[] |
cordis.yml |
Leaf wiring | the two backends + hmr + one @deepseek-ai/dsh-stdio-demo entry carrying the app config |
The spine, UI, persistence, and boot glue all live in @deepseek-ai/dsh-stdio-demo and the bundle it loads — this folder holds only the demo-specific mocks and the leaf wiring.
Run
pnpm run demo:echo
# or:
node --expose-internals --import tsx packages/examples/stdio-demo/src/bin.ts examples/echo-agent/cordis.yml
Type a message and press Enter. "echo " triggers a tool call round-trip (the mock model requests the echo tool, which echoes the text uppercased, and the next model step acknowledges it).
The session is persisted under .sessions/ relative to the directory you launch the demo from. pnpm run demo:echo runs from the repo root, so the logs land in <repo-root>/.sessions/cwd-<hash>/ (one .jsonl log per session). Clean up with: rm -rf .sessions
