handsontable-skills

Use this skill when the user works with HyperFormula (HF) — a headless, open-source TypeScript spreadsheet calculation engine. Use it when the user: mentions HyperFormula or HF; wants to integrate Excel-like formulas into a JS/TS app; evaluate formulas programmatically in a browser or Node.js; simulate spreadsheet or Excel calculation behavior server-side; run calculations over data parsed from XLSX files (e.g. via SheetJS) in code; build a pricing engine, financial model, or what-if analysis in code; define custom spreadsheet functions or named expressions outside of a UI context. Do NOT use this skill for: general Excel questions unrelated to HF; general Google Sheets questions; generic spreadsheet formula-syntax questions outside an HF context; formulas used inside Handsontable (use the "handsontable" skill instead).

Use this skill whenever the user asks about Handsontable — a JavaScript data grid component with spreadsheet-like UX. Triggers include: mentions of "handsontable", "HotTable", "data grid", "@handsontable/react-wrapper", spreadsheet component in React/Angular/Vue, HyperFormula formulas inside a grid, cell types (dropdown, checkbox, date, numeric) in a grid context, or questions about Handsontable theming, plugins, hooks, configuration options, or column/row features. Also trigger when the user wants to add an editable spreadsheet-like table to a web app, or asks about copy/paste, sorting, filtering, frozen rows/columns, merged cells, or context menus in a grid. This skill covers Handsontable used with any framework (React, Angular, Vue 3, vanilla JS) and HyperFormula as the Formulas plugin engine inside Handsontable. Do NOT use this skill for headless/standalone HyperFormula usage without Handsontable — that is covered by the separate "hyperformula" skill.
