Journey fit
Canonical shelf is Operate because reminders support ongoing solo-builder cadence after the product exists, not one-off build tasks. Iterate fits recurring check-ins, follow-ups, and habit nudges while you ship fixes and side projects in parallel.
How it compares
Desktop reminder MCP integration, not a standalone agent skill or SaaS task board.
