git mv per the regrouping RFC: the five human-collaboration seams and tui join packages/interaction/, app-boot becomes packages/boot/, and jsonrpc joins the renamed scaffold/ (formerly sdk/) as its server half beside client/protocol/create-sdk/helper/scripts/telemetry, whose folders drop the legacy sdk- prefix. Three new group README triplets replace the ui/ and sdk/ ones; tsconfig references/paths/globs, knip keys, vitest globs, gate scripts, catalogs, docs, and the lockfile follow. Adds the four settled FIXME rename markers (dsh-sdk-server, dsh-sdk-telemetry, dsh-sdk-helper, dsh-sdk-scripts). The scaffold folders diverge from their npm names until those renames land, so tsconfig.base.json maps the three affected names explicitly beside the group wildcard. Also repairs two pre-existing stale-path classes the strengthened sweep surfaced: docs/web-styling.md's retired web-ui host package and type-model spec fixture-literal joins. app-boot's three Loader-composition specs time out at the default 5s under full-suite parallel load on this filesystem (pre-existing; pass isolated with --testTimeout=30000); interaction/scaffold/boot suites otherwise green (687 passed).
@deepseek-ai/dsh-acp-demo
English | 中文
ACP automation server app: the default agent spine, client-created agents through @deepseek-ai/dsh-acp, JSONL persistence, and semantic checkpointing behind one JSON-RPC stdio bin. Programmatic clients create fresh sessions; this package mounts no human UI.
Composition
| Plugin | Role |
|---|---|
@deepseek-ai/dsh-agent-spine-demo |
Providerless agent spine with no pre-created agents; session/new creates each agent. |
@deepseek-ai/dsh-session-persistence-jsonl |
Durable session logs used by checkpointing, observability, and snapshot replay. |
@deepseek-ai/dsh-session-checkpoint-policy |
Durability barriers before model calls and top-level tool effects, plus completed-step checkpoints. |
@deepseek-ai/dsh-session-query-sqlite |
Derived exact/FTS session-query service, opened before the ACP transport so leaf consumers are ready for the first model request. |
@deepseek-ai/dsh-acp |
Automation-only ACP transport over stdin/stdout. |
The app does not install commands, user interaction, session navigation, configuration pickers, or a stdout logger. It owns these plugins through one ordered effect so the query service is ready before ACP accepts work and ACP sessions quiesce before checkpointing and persistence detach. Leaf configurations supply LLM, executor, sandbox, approval, filesystem, and model-facing tool plugins.
Config
| Key | Default | Routed to |
|---|---|---|
provider |
required | Provider route for each ACP-created agent. |
model |
required | Model for each ACP-created agent. |
maxParallelToolCalls |
agent-loop default | Positive-integer tool-call concurrency cap; 1 is serial. |
persona |
— | Deployment persona template for dsh-system-prompt. |
toolOrder |
lexicographic | Explicit model-facing tool order for dsh-system-prompt. |
tools |
{ mode: 'native' } |
Native, Code Mode, or combined model tool transport. |
dshHome |
$DSH_HOME or ~/.dsh |
Harness home shared by bash and local skill discovery. |
sessionTitle |
spine example limits | Durable fallback-title limits; titles remain off the ACP wire. |
persistenceRoot |
./.sessions |
JSONL backend root and parent directory of the derived session-query.db index. |
packChunks |
true |
Pack consecutive delta-chunk events in storage. |
persistenceCompression |
zstd |
Checksummed Zstandard frames or raw none. |
workspaceContext |
required | Workspace-instruction byte budget/config, or false. |
skills |
owner defaults | Skill registry, local provider, and model-facing skill tool. |
toolBash |
owner defaults | Model-facing bash tool config. |
toolTasks |
owner defaults | Generic background-task control config, or false. |
goals |
owner defaults | Persisted same-session goal domain and model tools, or false. |
The shipped examples/acp-agent/cordis.yml adds the DeepSeek adapter, sandboxed bash and filesystem providers, one-shot approval policy, compaction, subagents, workflows, hooks, and model-facing tools. The app supplies the derived session-query index, while the model-facing query consumer remains an explicit leaf opt-in. Snapshot overlays replace only nondeterministic providers or policy values.
Bin
dsh-acp-demo [--config path-to-cordis.yml] (short form -c; default ./cordis.yml) loads the gitignored .env, except in replay mode; DSH_SNAPSHOT=replay selects the sibling cordis.snapshot.yml; stdin EOF disposes the context and flushes sessions before exit. Loader's installed optional node-addon-require-builtin peer resolves bare plugin specifiers for the built bin under plain Node. Diagnostics use stderr because stdout is the ACP wire.
Model Experience
Indirectly, through dsh-agent-spine-demo and the leaf's model-facing plugins. ACP prompt text becomes the ordinary logged user message; protocol metadata and permission choices do not enter the model request.
KV Cache effect
Append-only per session; the app adds no request-prefix content itself.
Known Limitations and Deferred Work
- JSONL persistence is fixed — a different backend requires another composition.
- Sibling plugins can corrupt stdout — the app cannot prevent another entry from writing non-protocol bytes.
- Fresh automation sessions only — resume and human interaction belong to other front doors.
