Quick Answer
Hand off a Lovable app by freezing the product scope, writing down the source of truth for auth and billing, marking every fake or temporary flow, and moving dangerous logic into code ownership before launch.
What this actually helps with
keeping the useful parts of the generated MVP
reducing blind cleanup time for the developer
making auth, billing, and roles auditable before launch
preventing a rewrite of the wrong things first
The hard part most founders skip
The real handoff problem is not abstract code quality. It is blurred ownership.
The generated app often looks finished while the dangerous layers are still unclear:
billing state lives in two places
auth works on the happy path only
admin routes still exist because they were convenient during the build
nobody can say what the app actually trusts for permissions
What AI can help with
AI is still useful for:
summarizing current flows
cleaning up repetitive UI
documenting component patterns
accelerating bounded cleanup after the handoff
What AI usually gets wrong
AI usually misses:
entitlement state after Stripe events
owner-based data access
role enforcement beyond the UI
preview URLs and auth redirects
hardcoded keys and temporary admin paths
What to do manually before the handoff
1. Write the product truth in one page
Give the developer a simple handoff note:
what the app does
who can log in
what paid users get
which flows are live
what must not break this week
2. Mark every fake or temporary workflow
List:
placeholder data
fake success states
admin shortcuts
partial Stripe flows
routes that only work in preview
3. Name the source of truth for access
If you cannot point to one trusted record for premium access or roles, fix that first.
4. Freeze wide-scope prompting
Right before a developer handoff is the worst time to keep making broad AI edits. Stop prompting for vague improvements and stabilize the baseline instead.
A workflow that actually works
Stabilize the repo and environment variables.
Audit auth, billing, roles, private data, and deploy setup first.
Rewrite only what is dangerous or structurally unclear.
Keep using AI for bounded UI changes after the dangerous layers are owned.
