What Flows just did
Based on your request to build SaaS MVP Builder, Flows created 6 implementation stages and 22 checks.
You asked for: Ship a working SaaS MVP: landing page, auth, one core feature that delivers value, and a paid-plan placeholder.. Flows generated 6 stages because the application requires A landing page with clear value proposition and CTA; Working signup/login with sessions; One core feature working end to end with real data. Each stage tells your AI builder what to do, tests whether it actually worked, and gives a repair instruction when it fails. These checks are designed to catch: Five shallow features instead of one working one; A dashboard of hardcoded demo data; Auth that loses the session on refresh.
Example failure
The form reported success, but no database record was created.
What Flows does
Flows detects the failure, generates a repair instruction, reruns the test, and stores the passing evidence.

Copy to external builder
Copies a prompt for Claude/Cursor/etc. Records prompt_copied only — not execution, commits, or checks.
Execute through Oort
Requires Sign in with Oort + a provider connection (BYOK). Keys stay on Oort. A model name in the dropdown is not the same as a live connection.

Check off: Value proposition fits in one sentence
Add a proof note on each check — a checkbox alone is weak proof.
Probes & advanced tools are under “More verification tools”. Experience level: Settings.

App persistence (create → read → assert token)
Body template: {"probe":"{{token}}","title":"flows-probe-{{token}}"}. Needs CORS-readable public create/list endpoints (or inconclusive). Badge only when create→read→refresh finds the token (detects false success).
Two-account authorization (User B cannot see/change User A)
Authorization evidence source: Cross-account ownership test (trust level 5/6). These are not equivalent. Unauthenticated probe alone is weaker (source: unauthenticated API probe). Tokens stay in this browser session only — not uploaded to Flows servers.
Generated edge-case tests (review / approve)
- api_probe Submitting the form empty is rejected with a clear error
- api_probe Each required field can be omitted and fails validation
- api_probe Malformed email is rejected
- api_probe Malformed phone is rejected when phone is collected
- api_probe Duplicate submission does not create two records
- api_probe Double-click submit creates only one record
- false_success_probe Failed request does not show success
- browser_automation Refresh during submission does not leave corrupt state
- api_probe Oversized input is rejected
- api_probe Unsafe strings do not execute or break storage
- api_probe Logged-out users cannot open protected pages
- api_probe Protected API rejects requests without credentials
- api_probe Expired session cannot mutate data
- browser_automation Logout in one tab invalidates mutations from another
- cross_account_probe User B cannot see or change User A’s data
- cross_account_probe Participant cannot call coach/admin endpoints
Generated from this route’s signals — you approve; you do not invent security tests.
Content probe (GET body contains text)
In-product content probe reads response text when CORS allows — not full DOM/click automation. Playwright script is optional and external.

Step 1 of 6
Not startedDefine the MVP in one sentence
Force clarity: one user, one problem, one core action.
Flows keeps plan, checks, failures, and next steps connected
Your AI tool writes or changes the code
Repository grounds the plan only after inspect
Checks always carry a validation tier
How this plan was created
Plan from project details
Flows creates steps using the goal, requirements, stack, platform, and details you provide.
- Project description
- Selected template / route
- User-entered stack
- Constraints and notes
- SaaS MVP Builder
No repository inspection implied. Connect and inspect a codebase to ground steps in real files.
Codebase access
Checking GitHub…
Or paste a repository URL manually
Use these instructions in Claude, ChatGPT, Cursor, Emergent, or another builder.
Define this SaaS MVP with brutal focus. Produce: a one-sentence value proposition ('X helps Y do Z'); the single core action a user performs to get value; the minimum data model behind that action; the 3 pages the MVP needs (landing, auth, dashboard/feature); and an explicit NOT-list of features we will not build yet. Keep the core action count to exactly one.
Project context
Copies the project goal, technical details, current step, previous progress, and checks so your AI tool understands what it is working on.
Expected after this step
A one-sentence value prop, one core action, minimal data model, and a NOT-list.
Should not happen
- ✕Five shallow features instead of one working one
- ✕A dashboard of hardcoded demo data
- ✕Auth that loses the session on refresh
- ✕Data leaking across users because queries do not filter by owner
Verify gate — prove this step works before continuing
Do not move on until every check is true. Add proof notes — a checked box alone is weak proof. Checks are manual by default; deploy/API probes live under “More verification tools” and do not auto-check boxes.
Do not continue if…
- !Five shallow features instead of one working one
- !A dashboard of hardcoded demo data
- !Auth that loses the session on refresh
- !Data leaking across users because queries do not filter by owner
Repair path — if this step fails
Use the Repair Prompt when a verify gate fails. Loop: Detected → Diagnosed → Repair issued → Changed → Retested → Resolved
Show repair prompt textShow
The MVP definition contains multiple core features. Cut it to ONE core action that delivers the value, and move everything else to the NOT-list.
Your notes for this step
Definition of Done
Final route-level requirements. Manual checks — separate from per-step verify gates. Completing step gates does not auto-check these. Route completion is not a production-ready claim.
