Design a System Component

Fill these in and the prompt below updates as you type. Anything you leave blank stays as a placeholder.

I need to design {{component_name}} for a {{application_type}}.

Context:
- Scale: {{scale}}
- Existing stack: {{stack}}
- Key constraints: {{constraints}}

Give me:
1. A high-level design with the main components and how they interact
2. The data model (tables or document schemas)
3. The API surface (endpoints or function signatures)
4. Where the hard problems are and how you'd approach them
5. What you'd defer to a v2
