Systematic trace through Zed (crates/agent_ui thread_view.rs + crates/acp_thread): kind:execute routes a tool call onto the terminal-card layout, whose header (render_collapsible_command) has NO disclosure toggle, whose body content renders only when is_open — a flag only a real terminal entity can ever set — and which suppresses the Raw Input view outright. Every prior attempt (rawInput, pending content, completed content) targeted slots that layout structurally never renders; the one slot it always shows is the TITLE, which said "Run code". codex-acp confirms the idiom: execute cards are titled with the command itself. presentCall now titles the card with the program (rawInput kept as the canonical input slot); presentResult omits the title — an update replaces only provided fields, so the program header persists — and carries the captured output as content. Goldens re-recorded; the unit test pins title-carries-program on both frames.
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, @deepseek-ai/dsh-acp-agent) and the @deepseek-ai/dsh-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.ymlloading the@deepseek-ai/dsh-stdio-agentapp - 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-agentis the adapter
Run with: pnpm run demo:echo. When prompted, type "echo " 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 for details.
Its code-mode.cordis.yml overlay flips the same tree 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 the other tools by writing a program whose output it curates. Run with: pnpm run demo:code-mode (the REPL is the default UI; acp as the argument serves the acp-agent example's same-shaped overlay instead) — see the Code Mode section for what to try.
acp-agent
An agent demo exposed as an Agent Client Protocol (ACP) server over JSON-RPC stdio, via the @deepseek-ai/dsh-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 for the Zed setup and the snapshot-test design.
