Tianyi Cui 3f83a4ee96 review: the persona becomes the system-prompt plugin's deployment config
Review round 2 (tianyicui inline comments):

- dsh-system-prompt itself registers the harness:identity (-100) and
  deployment:persona (0) sections — they must survive a swapped loop
  plugin, so they leave dsh-agent-loop; the persona text is the plugin's
  own validated 'persona' config. The model/cwd variables STAY on the
  loop: runtime facts of the agents it drives.
- AgentOptions.systemPrompt is deleted with all its forwarding plumbing:
  the app configs' systemPrompt keys become 'persona' routed through
  dsh-agent-core (schema = z.intersect of the owners'), the ACP bridge
  and tool-subagent stop carrying persona configuration, and subagent
  children now render the deployment persona like every other agent.
- Example personas drop transport/interface trivia (ACP, CLI) — facts
  irrelevant to the model.
- Root CONTEXT.md removed (not idiomatic); its persona definition was
  wrong under the new ownership anyway.
- Docs, READMEs, the prompt-variables RFC, and generated catalogs
  updated; new loop test pins the assemble-waterfall escape valve
  (an emptied assembly sends NO system field).

@deepseek-ai/dsh-acp-agent

The ACP server app: a Cordis app plugin that composes the providerless agent spine (@deepseek-ai/dsh-agent-core) with the front-door cluster an Agent Client Protocol server needs, and a bin that boots a leaf cordis.yml speaking ACP JSON-RPC on stdio.

It is the structured counterpart to @deepseek-ai/dsh-stdio-agent: both consume the same spine, but this one bakes in the OPPOSITE front-door cluster.

What it bakes in — and what it deliberately omits

stdout is the ACP JSON-RPC channel, so the cluster is defined as much by what it LEAVES OUT as what it includes:

Plugin Why
@deepseek-ai/dsh-agent-core the spine, pre-creating no agents (ACP session/new creates them on demand)
@deepseek-ai/dsh-session-persistence-jsonl durable JSONL session log (the bridge advertises loadSession)
@deepseek-ai/dsh-acp the bridge that owns stdout for JSON-RPC
console logger omitted — it writes to stdout and would corrupt the protocol frames (the stdout-purity footgun)
hmr omitted — the editor owns the subprocess

Because the package wires no logger entry, an ACP leaf has nothing to get wrong by default: it only picks backends, so the common mistake — copying a console-logger entry from the stdio config — has no place here. (A leaf author technically can still add @cordisjs/plugin-logger-console as a sibling entry; the package can't forbid that. So the rule stands: never add a stdout logger to an ACP leaf — stdout is the JSON-RPC channel. Use a stderr exporter if you need logs.)

Config

Key Default Routed to
model (required) the per-session agent template the bridge creates agents from
persona the deployment persona template (may reference {{model}}/{{cwd}}), routed to dsh-system-prompt
persistenceRoot ./.sessions the JSONL backend's root directory

The leaf supplies the swappable backends: an LLM adapter (llm-deepseek for the real model, llm-replay for keyless snapshot replay) and a bash executor (bash-local).

The bin

dsh-acp-agent [path-to-cordis.yml] (default ./cordis.yml):

  • loads a gitignored .env from the cwd — skipped in snapshot REPLAY so a stray key can never trigger a live call;
  • honors DSH_SNAPSHOT=replay by booting the sibling cordis.snapshot.yml (the keyless replay tree, llm-replay in place of llm-deepseek);
  • in a snapshot run, disposes the context on stdin EOF so the session log is fully flushed before exit.

Run it under node --expose-internals: the cordis Loader resolves the config's bare plugin specifiers through its internal module loader, active only under that flag. (demo:acp runs under tsx, whose tsconfig paths map resolves them instead.)

All diagnostics go to stderr — stdout is the protocol.
