Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
Connect Lark (Feishu) to OpenClaw for bidirectional messaging with full rich content support.

Enable these scopes in Lark Developer Console → Permissions & Scopes: Messaging: im:message - Send and receive messages im:message:send_as_bot - Send messages as bot im:resource - Download message resources (images) Documents (optional): docx:document:readonly - Read documents wiki:wiki:readonly - Read wiki spaces sheets:spreadsheet:readonly - Read spreadsheets bitable:bitable:readonly - Read bitables drive:drive:readonly - Access drive files
Main webhook bridge. Receives Lark events, forwards to OpenClaw, sends replies. FEISHU_APP_ID=cli_xxx node scripts/bridge-webhook.mjs
Install as systemd service for auto-start: node scripts/setup-service.mjs # Creates /etc/systemd/system/lark-bridge.service
Images in messages are: Detected from post content or image message type Downloaded via Lark API using message_id and image_key Converted to base64 Sent to OpenClaw Gateway as attachments parameter attachments: [{ mimeType: "image/png", content: "<base64>" }]
In group chats, the bridge responds when: Bot is @mentioned Message ends with ? or ? Message contains trigger words: help, please, why, how, what, 帮, 请, 分析, etc. Message starts with bot name Otherwise, messages are ignored to avoid noise.
Use the feishu-doc skill to read Lark documents: node skills/feishu-doc/index.js fetch "https://xxx.larksuite.com/docx/TOKEN" Supported URL types: /docx/ - New documents /wiki/ - Wiki pages (auto-resolves to underlying doc) /sheets/ - Spreadsheets /base/ - Bitables (multi-dimensional tables) Permission Note: Documents must be shared with the bot, or the bot must have tenant-wide read permission.
Document not shared with bot → Add bot as collaborator Missing scope → Enable docx:document:readonly in console
Check webhook URL is accessible: curl http://YOUR_IP:3000/health Verify webhook in Lark console shows "Verified" Check bridge logs: journalctl -u lark-bridge -f
Old bridge version → Update to use attachments for images
Missing im:resource scope → Enable in Lark console Token expired → Bridge auto-refreshes, restart if stuck
# Check status systemctl status lark-bridge # View logs journalctl -u lark-bridge -f # Restart systemctl restart lark-bridge
