sandbox-acp-agent's whole surface moves into examples/acp-agent following the example's existing multi-variant shape (the code-mode/both-mode overlays): sandbox.cordis.yml + its replay overlay, the four snapshot scenarios (config-options / mode-switching / escalation-approved / escalation-rejected) as a 'sandbox' header class over per-scenario configPath — goldens byte-identical, zero re-recording — and escalation.e2e.ts unchanged apart from the config path. One ACP example remains; demo:sandbox-acp keeps its name and boots the variant. References (both RFCs, group/package READMEs, the examples table and test map, the e2e workflow comment) now point at the variant.
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 its registry contribution is the reserved run_code transport plus a generated TypeScript SDK section, and the model 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.
cordis-agent
The self-referential demo: the coding spine plus @deepseek-ai/dsh-tool-cordis, whose three tools (cordis_inspect / cordis_mount / cordis_unmount) let the agent inspect the live cordis runtime it runs inside, mount model-written plugins into it (an event listener, a brand-new tool for itself, or a service another mount injects), and dispose them again — all dynamic mounts grouped under one cordis-dynamic fiber subtree. The ctx.fs/ctx.web services ride along provider-only, as the capabilities those plugins build on.
Run with: pnpm run demo:cordis (needs DEEPSEEK_API_KEY). See cordis-agent/README.md for the staged demo script and the toolset RFC for the design and sandbox caveats.
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.
The sandbox variant (sandbox.cordis.yml) swaps the bash executor for the sandbox stack (@deepseek-ai/dsh-sandbox-local + @deepseek-ai/dsh-bash-sandbox — the one-entry executor swap the ctx.bash capability seam exists for) and mounts @deepseek-ai/dsh-user-approval — the composition where the approval loop is LIVE: a sandbox denial escalated by the model becomes a session/request_permission prompt in the editor, and "Allow once" runs exactly that command under the wider mode. Run with: pnpm run demo:sandbox-acp (needs DEEPSEEK_API_KEY; bwrap, a Landlock-enforcing kernel, or macOS for confined runs).
