Check Authorization Separately From Hidden UI
By SayCraft Team · 2026-08-13 · 4 min read
Check authorization separately from hidden UI by asking whether a user can actually perform an action, not just whether the button is visible or hidden. In SayCraft, a product conversation can become a working preview, but you still need a separate human review of permissions and role boundaries because interface hiding alone does not prove the access model is correct.
Community signal: In community discussions about vibe coding maintenance and prototype breakpoints, builders often note that a screen can look right while the underlying access behavior is wrong or incomplete. That is anecdotal, but it is a practical warning: UI appearance is not the same thing as authorization.
Why hidden UI is not enough
A hidden button does not necessarily mean a user lacks access. It may only mean the interface is not showing the action. For a founder reviewing a prototype, that distinction matters because authorization is about what the user is allowed to do, not what they can see on one screen.
SayCraft can help you define the product and iterate on a preview, but it does not replace a separate permissions review. If your app involves invitations, account ownership, payments, shared records, or admin settings, you need to inspect the rules explicitly.
- Visibility is not the same as permission.
- A clean screen can still have the wrong access behavior.
- Sensitive actions deserve separate review.
Start with role-based questions
The easiest way to review authorization is to ask role-based questions. What can the owner do that a collaborator cannot? What can a member edit but not delete? Which actions should require an admin or owner? If you cannot answer those questions clearly, the permission model is not ready for a larger build.
This is where role definitions from the planning stage pay off. When the intended actions are written down, you can test the prototype against the rules instead of guessing what the interface implies.
- Who can create?
- Who can edit?
- Who can delete?
- Who can invite others?
- Who can change billing or ownership?
Test the action, not just the page
Review a prototype by trying to perform the sensitive action with different roles. If a collaborator should not access billing, confirm that the app actually blocks the action. If a viewer should not edit records, confirm that the data remains protected at the action level, not merely hidden from the navigation.
This is a product review step, not a security guarantee. The goal is to catch mismatches between the intended role model and the preview before they spread into the next iteration.
- Try the same action under different roles.
- Check what happens when access should be denied.
- Make sure denial is understandable, not ambiguous.
Watch for accidental permission leaks
A prototype can accidentally expose actions through direct URLs, stale views, reused components, or overlooked edge states. You do not need to know the technical cause to notice the symptom. If a user can reach a screen they should not use, that is a review finding worth recording.
Because SayCraft turns a conversation into a working preview, it is useful for exploring product flows. But any preview that touches access boundaries should be reviewed carefully by a human before you assume the model is safe or complete.
- Look for actions reachable from multiple paths.
- Check whether restricted state is still reachable.
- Record mismatches between the intended role and the actual result.
Separate product scope from permission scope
It is tempting to fold permissions into the general feature list, but keeping them separate makes the review clearer. One section of your brief should describe what the product does. Another should describe who can do what. If those two sections blur together, you may miss an access problem because the feature seems fine on the surface.
This separation also helps with handoff. When you later discuss the app with a technical reviewer, the intended permissions are easier to audit because they are documented independently from the visible UI.
- Product scope: what the app is for.
- Permission scope: who can do what.
- Review both before expanding the preview.
Use a simple founder checklist
A founder-friendly checklist can catch most early authorization issues: define the roles, list the sensitive actions, test the actions under each role, and record anything that depends on hidden UI. If the action is important enough to control, it is important enough to test directly.
That keeps the work bounded and realistic. SayCraft helps shape the preview from the product conversation, but your own review should decide whether the access model still needs refinement before anyone treats the app as more than a prototype.
- Define roles first.
- List sensitive actions second.
- Test each action under the wrong role as well as the right one.
- Treat hidden UI as only one signal, not the final answer.
