Feishu Bridge

Bridge Feishu bot messages to ThinkFleet Gateway over local WebSocket.

Architecture

Feishu user → Feishu cloud ←WS→ bridge.mjs (local) ←WS→ ThinkFleet Gateway → AI agent

• Feishu SDK connects outbound (no inbound port / public IP needed)
• Bridge authenticates to Gateway using the existing gateway token
• Each Feishu chat maps to a ThinkFleet session (feishu:<chatId>)

Setup

1. Create Feishu bot

1. Go to open.feishu.cn/app → Create self-built app → Add Bot capability
2. Enable permissions: im:message, im:message.group_at_msg, im:message.p2p_msg
3. Events: add im.message.receive_v1, set delivery to WebSocket long-connection
4. Publish the app (create version → request approval)
5. Note the App ID and App Secret

2. Store secret

mkdir -p ~/.thinkfleet/secrets
echo "YOUR_APP_SECRET" > ~/.thinkfleet/secrets/feishu_app_secret
chmod 600 ~/.thinkfleet/secrets/feishu_app_secret

3. Install & run

cd <skill-dir>/feishu-bridge
npm install
FEISHU_APP_ID=cli_xxx node bridge.mjs

4. Auto-start (macOS)

FEISHU_APP_ID=cli_xxx node setup-service.mjs
launchctl load ~/Library/LaunchAgents/com.thinkfleet.feishu-bridge.plist

Diagnostics

# Check service
launchctl list | grep feishu

# Logs
tail -f ~/.thinkfleet/logs/feishu-bridge.err.log

# Stop
launchctl unload ~/Library/LaunchAgents/com.thinkfleet.feishu-bridge.plist

Group chat behavior

Bridge replies only when: user @-mentions the bot, message ends with ?/？, contains request verbs (帮/请/分析/总结…), or calls the bot by name. Customize the name list in bridge.mjs → shouldRespondInGroup().
