Can a prompt replace Capsule?

Build a CRM whose job is not finished when a deal is won.

Stack: your choice of server framework, Postgres, Docker Compose, one command to run.

Sales half: Contacts, Companies, Opportunities. An Opportunity has a value, an expected close date, a stage, and one owner. Stages are configurable and the last two are terminal: Won and Lost.

Delivery half — this is the point of the build. Define Project Templates: an ordered list of task titles, each with an offset in days from project start and an optional default owner. When an Opportunity is moved to Won, the app asks which template to apply (or none), then creates a Project linked to the same Company and Contact, with every task materialised at start date plus its offset. The project keeps a link back to the opportunity that produced it, and the contact's timeline shows both.

A Project has a status, a due date, and a completion percentage computed from its tasks — never typed in.

Build one screen that mixes both halves: "this week" lists opportunities with a close date this week and project tasks due this week, in one list, sorted by date, with a badge saying which side each came from. That single list is what a solo operator actually opens in the morning.

Add notes with timestamps on contacts, companies, opportunities and projects; a tag system shared across all four; CSV import and export; and full-text search.

Write tests for template materialisation — especially that a template applied twice does not duplicate tasks — and for the completion-percentage computation.

Do not build email sync, invoicing, or marketing campaigns. When a project is finished the flow ends; exporting to your accounting tool is a CSV, not an integration.
