What problem does it solve? Working with Feishu (Lark) online spreadsheets through an AI agent is error-prone: wrong command names, lost cell types, broken formulas after Excel migration, and unverified writes. This Skill provides a complete, verified command vocabulary and editing discipline for creating and manipulating Feishu spreadsheets through the lark-cli sheets interface. ## Core Features & Use Cases - Full spreadsheet lifecycle: Create workbooks, manage sheets, insert/delete/resize rows and columns, read and write cells with values, formulas, styles, comments, and embedded images. - Data objects: Build charts, pivot tables, conditional formats, filters, filter views, sparklines, and floating images as real native objects rather than static workarounds. - Formula correctness pipeline: Translate Excel formulas into Feishu-executable semantics (ARRAYFORMULA, MAP/LAMBDA, native array functions) and verify zero-error results with +formula-verify. - Use Case: Ask the agent to import an xlsx file into Feishu, add a summary pivot table grouped by region, draw a column chart excluding the total row, and apply conditional formatting to highlight overdue dates. ## Quick Start Ask the agent to read the Feishu spreadsheet at your sheet URL and summarize its sheets, then append a new row of data with inherited styling.
