Can a prompt replace Routine?

Build a tool that merges freeform notes with task scheduling: write a note, convert any line into a task with one action, then drag that task onto a calendar to time-block it — combining this catalogue's notes-taking pattern with its Amie entry's drag-to-schedule mechanic into one flow. Use Next.js/TypeScript with Postgres and the Google Calendar API (OAuth) for the calendar side. Build a simple daily-note editor, one Markdown note per day, like a running log. Let the user select any line of text and convert it to a task with a keyboard shortcut or button — this creates a linked task record referencing back to the source note line, without deleting the original text. Show tasks not yet scheduled in a sidebar list, and let the user drag any of them onto a weekly calendar view to create a real Google Calendar event at that time, the same transactional drag-to-schedule mechanic as the Amie entry. Mark scheduled tasks as such in both the note and the task list. Do not build multi-calendar-provider support, native cross-platform apps, or team-shared notes — those are out of scope; this is a single-user, single-calendar-provider tool combining two patterns already described elsewhere in this catalogue. Needs a Google OAuth app (free to register) with Calendar API access, plus hosting and a database.
