notion

Use BEFORE the first Notion read or write on ANY task touching Notion — the Notion API or its MCP — however trivial: a one-field rename, a page icon/cover, adding one row, a single select color, even just reading a page's title. Covers creating, editing, querying, or moving databases, data sources, pages, views (table/board/gallery/calendar/timeline/list/chart/dashboard/map/form), formulas, rollups, relations, blocks, icons, covers; and any Notion API/MCP error (validation_error, pagination, permission, 400/409). MANDATORY, never optional — "small", "quick", "obvious", or "well-understood" is the exact trap: every Notion edit still owes this skill's mandatory first steps (the ancestral-AGENTS.md sweep + house-style match) that a direct quick edit silently skips and corrupts. If the work touches Notion at all, load this FIRST.
