sheets-mcp

Shared doctrine for the Sheets skills. Use when you need deeper guidance on tool boundaries, request shaping, retries, mutation safety, formula doctrine, visualization, performance, or skill authoring. Do not start here for ordinary spreadsheet tasks; start with sheets-read, sheets-write, or sheets-diagnose.

Diagnose spreadsheet data quality and formula behavior through `sheets_analyze` and `sheets_formula_debug`. Use for profiling, lookup failures, import issues, and formula troubleshooting. Do not use for ordinary reads or direct mutations.

Inspect Google Sheets without changing them: spreadsheet metadata, values, formulas, notes, merges, formatting, and targeted grid structures through `sheets_get`, `sheets_read_values`, and `sheets_read_grid`. Use for reconnaissance, exports, audits, and formula inventories. Do not use for computed diagnostics, formula evaluation loops, or mutations.

Change Google Sheets data, formulas, structure, dashboards, charts, and styling through `sheets_edit` and `sheets_style`. Use for live mutations and dry-run planning. Do not use for read-only inspection or diagnostics.
