Feishu / Lark

Use this skill when the user asks for Feishu, Lark, or "飞书" integration work.

Ground Rules

• Feishu China APIs use open.feishu.cn; Lark international APIs use open.larksuite.com.
• Never hardcode app secrets, webhook secrets, tenant tokens, or user tokens. Use environment variables such as FEISHU_APP_ID, FEISHU_APP_SECRET, FEISHU_WEBHOOK_URL, and FEISHU_WEBHOOK_SECRET.
• If credentials are unavailable, produce setup instructions or a local stub instead of pretending the integration is live.

Common Use Cases

• Bot webhook messages
• App access token and tenant access token flows
• Docs, Sheets, Wiki, and Bitable reads/writes
• Approval or workflow status updates
• Feishu/Lark MCP server configuration

Workflow

1. Clarify whether the target is Feishu or Lark.
2. Identify the credential type: webhook, internal app, marketplace app, or OAuth user token.
3. Prefer official OpenAPI endpoints and signed webhooks when secrets are configured.
4. For MCP, build or configure a server that exposes narrow tools such as send_message, read_doc, append_sheet_row, or query_bitable.
5. Register the MCP server with codewhale mcp add, then run codewhale mcp validate and codewhale mcp tools.
6. Verify with a dry run, sandbox document, or read-back call before sending externally visible messages.

Ask for confirmation before sending messages, writing production documents, or changing approval/workflow state.
