Design a Lark Base for the user's business through a guided interview: find the one unit of work the business repeats, then derive the tables, links, formulas and a phased build order from the numbers the owner actually wants to see. Ends with a Base Blueprint document plus an acceptance test, ready to hand to whoever builds it. Use when the user wants a database designed for their business ("design my Lark Base", "what tables do I need", "help me build a database for my company", "帮我设计多维表格", "我的业务要怎么建表"), when their existing base has become one giant table and they want it restructured, or when they are unsure whether something should be a field, a select, or its own table. NOT for physically building or editing a Base via API or lark-cli (this skill produces the blueprint; building is a separate job), NOT for turning an already-filled database into reports or dashboards (that is breakthrough-database-to-dashboard), and NOT for setting up a second-brain vault (that is my-second-brain, installed separately).
