Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like "the xlsx in my downloads") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.

Clones a live web page into a single self-contained working HTML file that looks and lays out like the original, then validates the clone against the original in a loop until it matches. Use whenever a user points at a live URL and wants a faithful copy with NO redesign — phrasings like "clone this page to working HTML", "copy this page exactly", "save this page as a standalone HTML file", "make me a working copy of this site", "scrape this page into one HTML file", or "clone this page as-is". Reproduces the real markup, styles, and assets verbatim, keeping the original selectors and raw CSS — it does not restyle, improve, or rewrite anything. For the same look rewritten as clean semantic Tailwind (generated selectors replaced with real utility classes), use page-tailwindify; for a rebuilt and restyled version, use page-redesigner. Requires Claude in Chrome for capturing the source page.

Best practices for CSS development including modern layout techniques, naming conventions, theming, and maintainable stylesheet architecture

Use when the team needs to understand how data moves through frontend, backend, database, jobs, auth, and external integrations. Trigger on requests to map data flow, event flow, or state transitions across the system.

Use this when the team needs to improve latency, throughput, render performance, query speed, worker throughput, or resource usage across frontend, backend, database, or background systems.

Use this when frontend or service code needs help integrating with an API, provider, or internal backend contract. Trigger on requests about request flow, response handling, auth propagation, retries, or client-side integration patterns.

Use when the team needs to decide how frontend state should be organized across React or Next.js apps. Trigger on requests about local state, global state, server cache, forms, optimistic updates, or choosing between context, stores, and query-based patterns.

Use when the team needs a top-level system architecture spanning frontend, backend, auth, data stores, jobs, integrations, and deployment boundaries. Trigger on requests to design the overall system or validate a proposed architecture.
