DSH Agent Bridge

dsh-grok-acp is an adapter in DSH Agent Bridge. It connects Grok Build as a root agent through Agent Client Protocol (ACP), while preserving the native DSH Web session, composer, tool rendering, permission, and Markdown diff interfaces.

Grok Build is the only adapter today. The broader DSH Agent Bridge project name leaves room for future Codex and Claude Code adapters without tying the repository to one vendor or protocol.

Features

• Select DSH or Grok Build in the same dsh web composer.
• DSH mode reads the presets supplied by the current deployment and retains its installed models and plugins.
• Grok Build mode shows only models and reasoning efforts reported by ACP and hides unrelated DSH agent presets.
• ACP streaming output becomes native DSH answers, thoughts, tool calls, and diffs; plan updates use the collapsible task panel above the composer instead of repeating inside the answer.
• Each Grok turn uses one prominent activity summary. Click it to expand the full timeline; failures expand automatically. File changes, Markdown diffs, and permission requests remain independent.
• Grok permission requests use the DSH approval interface.
• DSH Full access also governs Grok ACP file access and approval behavior, including local Grok skills outside the workspace.
• Supports /usage, /context, /session-info, /btw, /model, /models, and /effort, including the /uasge compatibility spelling. /model and /models show only the active Harness's models.
• The harness can change while a session is blank and locks after the first message to prevent mixed-engine history.
• Grok sessions share one lazily started ACP process, which closes after the configured idle period.
• If the ACP process exits unexpectedly, the next request restarts it and resumes the matching Grok session.
• Installs as an independent DSH Bundle and does not modify the global DSH package or DeepSeek Harness source.

Architecture

DSH Web composer
       │
       ├── DSH ───────────► official AgentLoop, models, tools, and plugins
       │
       └── Grok Build ────► dsh-grok-acp ── ACP/stdio ──► grok agent
                                  │
                                  └── DSH session log / tool UI / approval UI

The plugin changes the agent preset while a session is blank and routes agent creation to either the official DSH AgentLoop or the Grok ACP agent. Model-visible output is still recorded in the DSH session log, so replay, titles, tool results, and diffs continue to use native DSH Web rendering.

Installation

Requirements

• macOS or another environment supported by the Grok Build CLI.
• Node.js ^22.19 or >=24.
• DeepSeek Harness 0.1.1-rc.2 installed globally, with a working dsh web command.
• Grok Build CLI installed and authenticated; grok --version must succeed.

Option 1: Install from npm (recommended)

Run:

dsh plugin --profile web add dsh-grok-acp@latest
dsh web

Open http://127.0.0.1:3080 and create a new session. Use Cmd/Ctrl + Shift + R if the browser still has an older client bundle cached.

Option 2: Install from a cloned project directory

Use this method when you want the latest GitHub source. Clone and build the project first, then give its directory directly to DSH:

git clone https://github.com/zmh2000829/DSH-agent-bridge.git
cd DSH-agent-bridge
npm install --legacy-peer-deps
npm run check
dsh plugin --profile web add "$(pwd)"
dsh web

$(pwd) means the full path of the current cloned project. If the project already exists locally, you can provide its absolute path directly:

dsh plugin --profile web add /Users/your-name/Projects/DSH-agent-bridge

Choose either installation method; do not run both. The Grok preset loads directly from the package and does not copy or overwrite ~/.dsh/harness-presets.

Verify the installation

dsh plugin --profile web exec dsh-grok doctor

The report should show that DSH, Grok, the Bundle, the preset, and the client build are ready.

Usage

1. Start dsh web and open port 3080.
2. Select “New session.”
3. Choose DSH or Grok Build below the composer.
4. DSH mode exposes four agent presets above the composer. Grok Build mode exposes the Grok model and reasoning-effort control inside the composer.
5. The harness locks after the first message. Create a new session to use another harness.

Configuration

The default command is grok agent --no-leader stdio.

Advanced deployments can override command, args, env, stateFile, disposeGraceMs, idleDisposeMs, yoloMode, and allowOutsideWorkspace in the Web profile's cordis.patch.yml entry. Sensitive actions require approval by default, and ACP file operations stay inside the session workspace. Enable both yoloMode and allowOutsideWorkspace only when you explicitly accept host-wide access.

ACP coverage

• Initialization and authentication: initialize, authenticate.
• Sessions: session/new, session/resume, session/load, session/close.
• Execution: session/prompt, session/cancel, session/set_config_option.
• Stream events: assistant, thought, tool call, tool result, plan, commands, model.
• Client capabilities: permission requests, fs/read_text_file, fs/write_text_file.
• Grok extensions: billing, BTW, session info, models.

Updating and uninstalling

Update an npm installation with dsh plugin --profile web add dsh-grok-acp@latest. For a source installation, run git pull, npm install --legacy-peer-deps, npm run check, and dsh plugin --profile web add "$(pwd)" from the cloned project directory.

Uninstall through the profile command, then restart DSH:

dsh plugin --profile web remove dsh-grok-acp
dsh web

Do not edit ~/.dsh/profiles/web/package.json by hand. Removing the plugin does not remove Grok authentication or Grok session files.

Development and publishing

npm install --legacy-peer-deps
npm test
npm run build
npm pack --dry-run

• lib/*.js contains the Node plugin and publication entry points.
• src/client/index.tsx is the Web client source; npm run build emits lib/client.js.
• presets/grok-build contains the packaged agent preset.
• .github/workflows/ci.yml tests, builds, and checks npm package contents on Node 24.

The project homepage, issue tracker, and source are available at zmh2000829/DSH-agent-bridge.

Security and limitations

• The browser bridge accepts only loopback hosts and rejects cross-site requests. Writes require same-origin JSON requests.
• ACP file operations stay inside the session workspace by default and reject escape through absolute paths, .., or symbolic links. yoloMode and allowOutsideWorkspace are explicit high-privilege options.
• The plugin currently targets DSH 0.1.1-rc.2. DSH prereleases may change internal AgentFactory or client Slot APIs; rerun tests and a real blank-session flow after upgrading DSH.
• Terminal-layout features from the Grok Build TUI cannot be embedded unchanged. This project reuses agent capabilities and commands and renders them through DSH Web.
• Codex and Claude Code adapters are not implemented yet. They should be separate adapters rather than conditional branches inside the Grok implementation.

Roadmap

• Extract a stable ExternalAgentAdapter interface.
• Add a Codex adapter.
• Add a Claude Code adapter.
• Add adapter capability discovery, settings UI, and a compatibility matrix.
