Stack

• Landing pages: Python (JSON → DOCX conversion)
• Web app: React 18, TypeScript, Express.js, Tailwind, Shadcn/ui
• PDF generation: jsPDF, html2canvas
• Excel export: SheetJS (xlsx)
• Publishing: Google Docs MCP

Key Decisions

1. 100-point rubric over subjective review — Quantifiable scoring ensures consistency across 29 blog posts. Agent 4 uses the same criteria every time.
2. INDEX/MATCH over XLOOKUP — XLOOKUP is Excel 365-only. Converting to INDEX/MATCH ensures templates work in Google Sheets, Excel 2016+, and LibreOffice.
3. Client-side PDF generation — No server-side rendering needed. jsPDF + html2canvas runs entirely in the browser, reducing hosting costs and complexity.
4. 3-batch landing page processing — 11 docs per batch prevents context overflow while maintaining consistency within each batch.
5. Connector cheat sheets as knowledge base — 7 product cheat sheets serve as the single source of truth for all agents, preventing capability hallucination.
