Where Claude fits in the workflow

Scope with Claude first

Cheaper to argue with Claude for 20 min than to burn Lovable cycles on the wrong product.

Prompt · Pre-Lovable scoping prompt

I'm about to build the app below in Lovable. Help me scope it tight before I start prompting.

Idea:
"""
{{1-line product description}}
"""

Output:
1. **Single core job** — the one thing this app does for the user. One sentence.
2. **3 to 5 screens** for v1, named.
3. **Data model** — tables + columns. Lovable defaults to Supabase.
4. **Auth + billing** — yes / no, what plan tiers if billing.
5. **Out of scope for v1** — 5 things I should NOT build first.
6. **The first prompt for Lovable** — the literal text I should paste into Lovable to get a usable v0.1 in one shot.

Be ruthless on scope. The whole point is to ship in a weekend.
