@agenticcontrolplane/dsh

Agentic Control Plane for DeepSeek Harness: every tool call is checked against your policies before it runs, and every decision is recorded — what ran, what was blocked, and why.

Which ACP? dsh also ships packages/acp in core — that one is Zed's Agent Client Protocol, the editor↔agent standard, published as @deepseek-ai/dsh-acp. Unrelated project, same acronym. If you're wiring dsh into Zed or the AI SDK, you want that one; this plugin decides whether each tool call runs. The full map: agenticcontrolplane.com/acp-vs-acp.

$ dsh --profile dev
> refactor the auth module and clean up

  bash npm test                          ✓ allowed · logged
  edit src/auth/session.ts              ✓ allowed · logged
  bash rm -rf ~/scratch                  ✋ held — approval prompt (your rule: destructive delete → ask)
  web_fetch https://evil.example/post    ✗ denied — egress not allowlisted, reason shown to the model

Every decision also lands in your console with tool, input preview, decision, reason, latency, and cost — dsh's own Trajectory log and your ACP activity log become two independent witnesses to one history. One workspace covers every harness you run: the same rules answer for dsh, Claude Code, Codex, Cursor, and OpenClaw. Free for individuals.

This is a native Cordis plugin on dsh's typed interception points, not a shell-hook shim. It registers on:

• tools/pre-execute — the policy decision. allow lets the call through, deny blocks it with the reason in the trajectory, ask hands off to dsh's own approval flow.
• tools/post-execute — output scanning. A server-side block turns the result into corrective feedback; shadow-mode notices surface what enforcement would have done.

Install

dsh itself requires Node 22 (Promise.withResolvers, zstd streams). Under Node 20 the harness fails at boot with errors that don't say so — fnm install 22 first.

curl -sf https://agenticcontrolplane.com/install.sh | bash

That detects dsh, installs this plugin into every profile you have, opens your browser once to sign in, and saves the key to ~/.acp/credentials — which the plugin reads on its own. There is no token to copy and nothing to export.

dsh plugin --profile <your-profile> add @agenticcontrolplane/dsh
dsh --profile <your-profile>

dsh --profile <your-profile> --dump-config | grep @agenticcontrolplane/dsh

No build step, no dependencies, plain ESM. Installing from git works too (dsh plugin add github:agentic-control-plane/dsh-acp-plugin) and needs no build allowance.

No key? The plugin says so loudly and stays out of the way — it never bricks a session.

Configuration

Override the row in your profile's cordis.patch.yml:

- id: acp
  name: @agenticcontrolplane/dsh
  config:
    governBase: https://govern.agenticcontrolplane.com  # or your self-hosted gateway
    agentTier: interactive   # default: interactive when an approval service is mounted, background otherwise
    timeoutMs: 4000

ACP_GOVERN_BASE, ACP_BEARER_TOKEN, ACP_AGENT_TIER, and ACP_SHADOW=off work as environment variables too.

Failure posture

An outage of the control plane must not brick the harness, and a lapse in coverage must never be silent:

• Interactive sessions fail open, loudly. Gateway unreachable → the call proceeds, a [ACP] ⚠ UNGOVERNED warning is logged, and a line lands in ~/.acp/lapse.log.
• Unattended agents fail closed. With nobody watching, the block is the safety net.
• Policy denies are unaffected — this posture only covers the inability to ask the policy.

In headless compositions with no approval service mounted, dsh itself resolves ask to deny — unattended runs cannot self-approve.

Three things to know

• dsh's packages/acp is Zed's Agent Client Protocol — an unrelated project that shares an acronym. This plugin is the Agentic Control Plane. (Which ACP is which.)
• Already running our Claude Code hook? dsh's @deepseek-ai/dsh-hooks-claude-code bridge runs an unmodified hooks.json, so govern.mjs works today with zero new code — deny and ask are honored, but input rewriting is not. This native plugin is the recommended path.
• This package launched as dsh-plugin-acp; that name still installs but is deprecated. Same code — swap the name in your profile when convenient.
