Code Mode is the point; the UI is just the surface it happens to wear. demo:code and demo:acp-code collapse into one dispatcher (scripts/demo-code-mode.mjs): `pnpm run demo:code-mode [repl|acp]` — repl (default) boots the stdio REPL over examples/code-agent, acp serves examples/acp-agent's code-mode overlay; each UI runs the exact node invocation its standalone script ran, and an unknown argument fails loud with usage. All nine references across READMEs, the RFC, the overlay header, and the keyless-smoke comment renamed. Smoked all three paths: usage exit 2, ACP initialize handshake, REPL boot + EOF.

# Examples

|
|
|
Runnable demos (not workspaces) that showcase how the harness is wired. Each example is now a **thin leaf**: a `cordis.yml` that picks the swappable backends (an LLM adapter, a bash executor), loads ONE app package, and may add optional product tools or demo-only mocks. The composition — the spine, the front-door cluster, and the boot glue — lives in the app packages ([`@deepseek-ai/dsh-stdio-agent`](../packages/ui/stdio-agent), [`@deepseek-ai/dsh-acp-agent`](../packages/ui/acp-agent)) and the [`@deepseek-ai/dsh-agent-core`](../packages/core/agent-core) bundle they share. There is no `start.ts`; the `demo:*` scripts invoke each app package's `bin`.

## echo-agent
|
|
|
|
A mock model + echo tool on the stdio chat app — the all-mock skeleton. The leaf swaps `dsh-stdio-agent`'s LLM backend to a local `mock-echo` adapter and adds a local `echo` tool. Demonstrates:
|
|
|
|
- A thin leaf `cordis.yml` loading the `@deepseek-ai/dsh-stdio-agent` app
|
|
- Registering a mock `LlmAdapter` (streaming scripted responses)
|
|
- Registering a tool via `ctx.tools.register()`
|
|
- "Swap the backend, keep the app" — the only difference from `coding-agent` is the adapter
|
|
|
|
Run with: `pnpm run demo:echo`. When prompted, type "echo <something>" to trigger a tool call round-trip.
|
|
|
|
## coding-agent
|
|
|
|
A REPL agent demo: DeepSeek V4 + the `read`/`write`/`edit` filesystem tools + the bash tool suite, `subagent` delegation, and the `todo_write` task tracker on the same `@deepseek-ai/dsh-stdio-agent` app. The UI is a terminal readline REPL.
|
|
|
|
Run with: `pnpm run demo:repl` (needs `DEEPSEEK_API_KEY` in the environment or a gitignored repo-root `.env`). See [coding-agent/README.md](coding-agent/README.md) for details.
|
|
|
|
## code-agent
|
|
|
|
The coding agent flipped to **Code Mode**: the worker-thread code runtime is loaded and the tool registry runs `mode: code`, so the model gets exactly one wire tool — `run_code` — plus a generated TypeScript SDK section, and composes bash/read/write/edit/todo_write by writing a program whose output it curates.
|
|
|
|
Run with: `pnpm run demo:code-mode` (needs `DEEPSEEK_API_KEY`; the REPL is the default UI — `acp` as the argument serves the acp-agent example's Code Mode overlay instead). See [code-agent/README.md](code-agent/README.md) for what to try and how it differs from coding-agent.
|
|
|
|
## acp-agent
|
|
|
|
An agent demo exposed as an **Agent Client Protocol (ACP)** server over JSON-RPC stdio, via the [`@deepseek-ai/dsh-acp-agent`](../packages/ui/acp-agent) app — drive it from Zed or any other ACP client. Also the home of the keyless snapshot tests.
|
|
|
|
Run with: `pnpm run demo:acp` (needs `DEEPSEEK_API_KEY`); `pnpm run demo:code-mode acp` boots the same server in Code Mode via the `code-mode.cordis.yml` overlay. See [acp-agent/README.md](acp-agent/README.md) for the Zed setup and the snapshot-test design.
