Implementation effort: The technical piece is only part of the work; the harder question is whether cosskill platform built with Next.js 16 on Cloudflare Workers, DeepSeek for AI inference, Cloudflare D1 (SQLite at edge) for persistence can be owned, monitored, and reconciled in production.
Practical read: Best read as a medium effort operational change with ROI upside when the pain is already measurable.
