@chubbyclaw/dsh-acp-full

A patch over @deepseek-ai/dsh-acp — the automation-only ACP server inside DeepSeek Harness — that also reports background work (subagents and detached jobs) over the ACP stream.

The upstream ACP surface carries only committed messages, thoughts, generic tool lifecycle, configuration and context usage. A platform driving a harness agent therefore cannot tell that the agent dispatched a subagent or left a shell running in the background. This change adds exactly that, using the draft agent-client-protocol#1992 notifications that claude-agent-acp already implements.

What it adds

Emitted only to a client that negotiated the capability in clientCapabilities._meta.jetbrains.air; every other client sees the stock ACP surface, byte for byte.

| Capability | Emitted updates | Source | | --- | --- | --- | | nativeSubagentSessions | subagent_spawned, subagent_state_update | the harness session/created and subagent/end lifecycle | | asyncTasks | async_task_spawned, async_task_progress, async_task_state_update | the ctx.jobs registry |

It also answers the draft _session/async_task/stop extension request by killing the named job, so a client can stop one detached job without touching the main turn.

How it runs

The harness stays stock DeepSeek Harness. This package is a profile for it, so the launch line still names the upstream binary:

npx -y @deepseek-ai/[email protected] --profile chubbyclaw-full-acp

The package ships both halves:

• lib/ — the patched bridge, a drop-in replacement for the stock acp row;
• profile/ — the ready chubbyclaw-full-acp profile: it disables the stock acp row and inserts this bridge, and declares which dsh runtime it targets (package.json → chubbyclaw.dshRuntimeVersion).

cclaw prepares that profile for the owner with no pnpm, no clone and no extra install step: npm pack @chubbyclaw/dsh-acp-full, extract lib/ into $DSH_HOME/profiles/chubbyclaw-full-acp/node_modules/@chubbyclaw/dsh-acp-full/ and profile/ into the profile root, then launch the pinned dsh above. The bridge's @deepseek-ai/dsh-* imports resolve to the harness installation, so no dependency tree is installed.

Repository layout

This is the only repository: the change lives as a patch over upstream, not as a fork of the whole harness.

| Path | What it is | | --- | --- | | lib/ | the built bundle and declarations — what npm ships | | profile/ | the chubbyclaw-full-acp DSH profile template | | patches/ | the change over upstream, one patch per commit | | scripts/build.sh | rebuilds lib/ from upstream at the pinned tag |

Rebuild

scripts/build.sh          # clone upstream at chubbyclaw.dshRuntimeVersion, patch, build, copy lib/
scripts/build.sh --test   # also run the upstream ACP test suite

DSH_UPSTREAM_TAG overrides the tag (default dsh-v<chubbyclaw.dshRuntimeVersion>). Bumping to a newer harness means bumping chubbyclaw.dshRuntimeVersion, refreshing the patch against the new tag, rebuilding, and publishing a new version.

Notes

• Built against @deepseek-ai/dsh-*@0.2.1-alpha.1; the peer versions are exact, so the loader only activates the bridge on that runtime. Widen them (and re-verify) only when a range has actually been tested.
• The platform client must advertise _meta.jetbrains.air and read the raw frames: the published @agentclientprotocol/sdk client rejects unknown sessionUpdate variants in its strict schema, while the server sends them unchanged.
• MIT, same as upstream.
