dsh-feishu-chat
Feishu (Lark) bot bridge for DeepSeek Harness: send a message to your Feishu bot and your DSH agent answers; the agent can also push messages back to Feishu.
Features
- Connect your Feishu bot by filling in App ID / App Secret — install the plugin, open
设置 → 飞书, paste the two values from Feishu Open Platform → your app → 凭证与基础信息, click 保存并重新连接, and the long connection comes up immediately. No config files to edit by hand. - Switch the bound workspace at any time — the same settings page lists every workspace the profile knows about (name + path + last activity). Click any row to retarget inbound Feishu messages to that workspace; the choice persists and the router reroutes live without restarting the harness.
- Two-way chat — Feishu messages arrive over the official WebSocket long connection (
im.message.receive_v1) and are delegated to a subagent of the bound workspace's latest session; the text reply is sent back to the same chat automatically. - Agent → Feishu tool — the model gets a
feishu_send_messagetool, so any session can push a message to the last chat that contacted DSH (or a givenchat_id). - Robust long connection — protobuf frame decode (
pbbp2), automatic ack, ping keep-alive, fragment merging (sum/seq), and reconnect with backoff, all in-process; stopping or updating the plugin tears everything down cleanly.
Install
# from npm (once published) or from this repo:
dsh plugin --profile web add dsh-feishu-chat
# or directly from GitHub:
dsh plugin --profile web add github:Qing45/dsh-feishu-chatThen restart dsh web and open 设置 → 飞书:
- Connect the bot — fill in the App ID and App Secret (Feishu Open Platform → your app → 凭证与基础信息), click 保存并重新连接. The status line turns green when the long connection is up.
- Pick the workspace — the workspace list shows every workspace the profile knows about (name + path + last activity). Click any row to bind it; inbound Feishu messages will be routed to that workspace's latest session from now on. Switch any time, no restart needed.
⚠️ This plugin is community third-party code — installing it runs it with your own permissions. Check the source before installing. Credentials stay local in $DSH_HOME/feishu-bot/config.json and are never committed or uploaded.How it works
| Piece | File | Role |
|---|---|---|
| Host entry | lib/index.js | Cordis plugin (export const name + export function apply), wires config, router, WS client, tool and HTTP routes |
| Feishu API | lib/feishu.js | node:https helpers: tenant token, send message, WS endpoint |
| WS client | lib/ws.js | in-process long connection: protobuf pbbp2.Frame, auto-ack, ping, fragment merge, reconnect |
| Router | lib/router.js | inbound message → resolve parent agent (initiator → live agent → resume) → subagent → reply |
| Config | lib/config.js | $DSH_HOME/feishu-bot/config.json persistence |
| Routes | lib/routes.js | HTTP routes for the settings UI (same-origin writes only) |
| Client | client/client.js | window.__ModuleLoader__.load bundle registering the 设置 → 飞书 section |
The package is a standard DSH bundle: package.json declares dsh.bundle.patch (layer insertion) and dsh.client (web bundle), and cordis.patch.yml inserts the plugin row into the profile tree.
Development / local install without a GUI restart
The profile's own patch layer ($DSH_HOME/profiles/<profile>/cordis.patch.yml) is hot-reloaded:
pnpm --dir "$DSH_HOME/profiles/web" add /path/to/dsh-feishu-chatThen append to cordis.patch.yml:
- insert:
- id: feishu-bot
name: 'dsh-feishu-chat'Refresh the browser — the settings section appears without restarting the harness.
Caveats
- One subagent is spawned per inbound message (no queueing); replies may arrive out of order under a burst.
- The TLS verification is relaxed (
rejectUnauthorized: false) so the long connection works behind corporate MITM proxies / broken certificate stores; review this trade-off for your environment. - The tool name is
feishu_send_message;chat_iddefaults to the most recent chat that contacted DSH.
