Beyond the mechanical conflicts (provider capability lines vs master's new inheritsParentContext field; generated catalogs regenerated rather than hand-merged; knip/lockfile), three master-side reworks required semantic adaptation of this branch: - The persona rework removed AgentOptions.systemPrompt, which was the structured-output instruction's channel. The instruction now rides the SAME final-request enforcement listener that injects the schema'd tool: appended per request to final.system (per-request wire state, not agent prompt state). Tests assert the wire request (adapter.requests) instead of child.options; the bare-direct-dispatch test pins the no-system arm. - Tool guidance moved out of deployment prompts into per-tool prompt sections; the examples' workflow paragraph became a tool:<toolName> section contributed by dsh-tool-workflow (explicit-ask-only policy), and both example personas resolve to master's minimal identity+behavior form. tool-workflow gains inject: systemPrompt (+ peer dep, tsconfig ref); the export-shape guard updated. - The uniform-RFC-format gate: the dynamic-workflows RFC restructured to the implemented/ skeleton (bare Status line; Proposal -> Decision; What-was-rejected -> Alternatives considered; new Consequences), and the overall-run-timeout deferral is now recorded in the RFC's Deferred list. The doc-graphs atlas classification gains the workflows seam (workflow-vm implementation, tool-workflow consumer). Master's harness-identity section made "empty assembled prompt" states unreachable through the loop, so the instruction-append is a plain undefined-ternary and the structured tests assert append-not-replace. All snapshot goldens (including workflow-run) replay unchanged. Full local CI-equivalent gate sequence green on the merged tree.
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.
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). See acp-agent/README.md for the Zed setup and the snapshot-test design.
