Each tool has a clearly distinct purpose with no overlap: append_row adds rows, create_sheet creates sheets, get_sheet_info retrieves metadata, read_sheet reads data, and write_sheet writes data. The descriptions clearly differentiate between operations on data versus structure.

All tools follow a consistent verb_noun pattern with snake_case naming (e.g., append_row, create_sheet, read_sheet). The verbs are action-oriented and predictable, making the set easy to navigate.

Five tools is reasonable for a Google Sheets server, covering core operations like reading, writing, appending, creating sheets, and getting info. It's slightly lean but functional; minor additions like update or delete operations could enhance it without being necessary.

The tools cover essential CRUD-like operations for Google Sheets: create (create_sheet), read (read_sheet, get_sheet_info), and write/append (write_sheet, append_row). A minor gap is the lack of explicit update or delete tools, but agents can work around this using write_sheet for updates.
