What problem does it solve? When working in the Feishu/Lark ecosystem, you often know a colleague's name or email but need their open_id to send messages, schedule meetings, or add them to groups. This Skill bridges that gap by resolving names and emails to open_ids, and reverse-lookup of open_ids back to names, departments, and contact details. ## Core Features & Use Cases - Name/Email to open_id Resolution: Search employees by name, email, or phone keyword with filters like chat history, enterprise email, tenant boundary, and employment status. - open_id Profile Lookup: Retrieve a user's name, department, email, and contact info from a known open_id, with support for union_id and user_id types. - Batch Fanout Queries: Query up to 20 names in parallel or batch-validate up to 100 open_ids in one call. - Use Case: You want to message "张三" — first search to confirm the correct person's open_id among same-name candidates, then hand the ID to the lark-im skill to send the message. ## Quick Start Ask the assistant to find the Feishu open_id for a colleague named 张三 so you can send them a message.
