dsh-feishu-gateway

  

English | 中文

Chat with your DeepSeek Harness (DSH) agent from Feishu (Lark).

A DSH plugin bundle that mounts a Feishu long-connection listener; every Feishu message is routed to a stable DSH session (resumed via the agents service, so multi-turn chats stay in the same session), and the agent's answer is replied as a Markdown-rich post message. It also supports /new to start a fresh session, a native Typing reaction while the answer is being produced, live streaming progress cards for long tasks, click-to-answer cards for permission approvals and the model's ask_user_question tool, and proactive push.

Features

• 💬 Full conversation — Feishu private chat / group @bot → DSH agent → reply
• 🔁 Persistent sessions — each Feishu conversation maps to one DSH session

(agents.resume / agents.create); /new (or "另起会话" / "新会话" / "重新开始" / "换个话题") starts a fresh one

• ⌨️ Native Typing indicator — while the agent works, the bot adds a

Typing reaction to your message (like hermes-agent's Feishu gateway); it stays until the answer is done, and is swapped for a CrossMark reaction on failure. No more "thinking…" hint text by default.

• 🎞 Streaming progress — long tasks report continuously: a live interactive

card streams the agent's thinking, tool calls, and answer draft as they happen (reporting.mode: 'stream', default). Set reporting.mode: 'final' to only receive the final result.

• 🃏 Click-to-answer cards — permission approvals (approval/request, e.g.

sandbox escalation) and the model's ask_user_question tool render as Feishu interactive cards: click ✅ 允许一次 / 🚫 拒绝 or an option button to answer. The click response instantly replaces the card with a decided state (buttons removed, result shown) plus a toast confirmation.

• ✍️ Markdown replies — plain rich-text (post) messages with the md

tag: bold, inline code, lists and links render natively, no cards needed

• 🧩 Web-only interactive fences degrade gracefully — model-emitted

dsh-ui interactive UI fences (e.g. from dsh-genui) only render in the Web UI; on Feishu they are auto-downgraded to a one-line readable hint (title extracted, "view in Web UI"), never a raw JSON code block

• 🤖 Full agent capability — the DSH agent runs with its own model and

tools (bash, files, subagents…), fully autonomous

• 📨 Proactive push — optional admin HTTP API (/api/push) to push text /

Markdown / cards to any user or group

• 🔌 No public network required — Feishu long connection, no webhook URL
• 🗂 Persistence — Feishu↔DSH session mapping survives restarts

Requirements

• DeepSeek Harness installed and built (dsh CLI), with DEEPSEEK_API_KEY

configured (the agent's model is used as-is)

• A Feishu open-platform self-built app with the bot capability enabled

(see below)

Feishu app setup

1. Feishu Open Platform → create a self-built app. 2. Enable the bot capability. 3. Grant permissions: im:message, im:message:send_as_bot (+ im:message:send_as_bot:readonly to read content). Publish a version. 4. Under Events & callbacks, choose long connection and subscribe to im.message.receive_v1 (no public URL needed). The same long connection also delivers card button clicks (card.action.trigger, used by the approval / Q&A cards) — no webhook URL required. 5. In Feishu, search the app name and add the bot as a contact.

> The Typing reaction indicator and card buttons need the bot to be able to > interact with messages in the chat (im:message). If the reaction API is > denied, the gateway automatically falls back to the hintText message.

Installation (as a DSH plugin)

Prerequisite: this package is published on npm and dsh is on your PATH.

The recommended setup mounts the gateway into the web profile: it runs in the same process as the DSH Web UI, so starting the Web UI also starts the Feishu gateway, and both share the same DSH agent. A standalone profile is also supported (see "Alternative" at the end).

Option 1 (recommended): mount into the web profile

The web profile is DSH's default GUI profile (dsh --profile web).

1. Edit ~/.dsh/profiles/web/package.json to add the dependency and bundle:

{
  "name": "dsh-profile-web",
  "private": true,
  "dependencies": {
    "@kriskwok/dsh-feishu-gateway": "^0.2.0"
  },
  "dsh": {
    "profile": {
      "bundles": [
        "@deepseek-ai/dsh-base",
        "@deepseek-ai/dsh-web-app",
        "@kriskwok/dsh-feishu-gateway"
      ]
    }
  }
}

2. Install dependencies in the web profile directory:

cd ~/.dsh/profiles/web && pnpm install

3. Edit ~/.dsh/profiles/web/cordis.patch.yml and fill in your Feishu app credentials:

- id: feishu-gateway
  config:
    feishu:
      appId: cli_xxxxxxxxxxxxxxxx
      appSecret: xxxxxxxxxxxxxxxxxxxxxxxx
    http:
      port: 3100      # optional admin API
      token: your-token

4. Start (or restart) the web profile:

dsh --profile web

> You can also use the one-shot script from this repository: > ./scripts/create-profile.sh (mounts into the web profile by default; > --standalone creates a standalone feishu profile instead).

Alternative: standalone feishu profile

To run the gateway without the Web UI, use a standalone profile:

mkdir -p ~/.dsh/profiles/feishu && cd ~/.dsh/profiles/feishu

cat > package.json <<'EOF'
{
  "name": "dsh-profile-feishu",
  "private": true,
  "dependencies": {
    "@kriskwok/dsh-feishu-gateway": "^0.2.0"
  },
  "dsh": {
    "profile": {
      "bundles": ["@deepseek-ai/dsh-base", "@kriskwok/dsh-feishu-gateway"]
    }
  }
}
EOF

cat > pnpm-workspace.yaml <<'EOF'
packages:
  - .
nodeLinker: hoisted
autoInstallPeers: false
EOF

pnpm install
# then create ~/.dsh/profiles/feishu/cordis.patch.yml with your app credentials
dsh --profile feishu

Configuration

All settings live in the feishu-gateway namespace (profile patch row or ~/.dsh/settings.yaml):

> Q&A cards in the web profile: ask_user_question answers go through the > single ctx.userQuestions provider slot. The gateway never claims that slot > (stealing it makes the Web UI's apiProxy host fail to start with > DUPLICATE_PROVIDER); it wraps service.ask at the service boundary > instead: sessions owned by a Feishu conversation are answered with Feishu > cards, while every other session continues through the registered UI > provider. Permission-approval cards work from Feishu in every setup. In a > standalone feishu profile, both ask_user_question and approvals are > answered from Feishu cards.

Session coexistence & self-healing

• Preset composition (tools!) — in preset-roster deployments (e.g. the web

profile), Feishu agents are composed from the deployment's agent preset (meta.agentPreset + preset mount), so the model gets its tools instead of treating tool calls as plain text.

• Web UI coexistence — sessions have a single live owner. When the Web UI

opens a session, the Feishu side takes over the running agent via agents.get() and drives the same session instead of failing with "while it is live" / "already exists"; both surfaces share one conversation.

• Wedged-session self-heal — if a crashed process leaves a session

permanently conflicted ("already exists"), the gateway mints a fresh session id, re-points the Feishu conversation at it, and continues chatting.

Admin HTTP API (optional)

Enable by setting http.port. Endpoints:

• GET /health — status
• POST /api/push — proactive push

{ "receive_id": "ou_xxx", "receive_id_type": "open_id", "msg_type": "text", "content": "{\"text\":\"hi\"}" }

• GET /api/sessions — Feishu↔DSH session mapping overview

Development

pnpm install
pnpm build     # tsc → lib/
pnpm test      # offline self-tests

> Note: @deepseek-ai/* packages are provided by the DSH host at runtime; for > local type-checking they are symlinked from your deepseek-harness checkout > (see the publish checklist).
