Codemix for UI/UX designers

Design from the story, not just the ticket.

A brief tells you what to draw. It rarely tells you why the product works this way, who else depends on the flow, or which decisions are already load-bearing.

Codemix gives designers a queryable model of the product's intent, flows and use cases. Ask the why questions while the design is still cheap to change. Hand off the context engineering needs to build the experience you meant.

React to plan changes in real time

Summary

  • React to accepted subscription changes without waiting for manual intervention.
  • Keep tenant access and limits aligned with the customer's current plan state.
  • Verify incoming billing events before any plan change logic runs.
  • Ignore unsupported Stripe event types safely while preserving retry behaviour for invalid signatures.

Proposals

Review what you're about to build before it's built.

A proposal describes the change in terms of product behaviour: what users will experience, what's in scope, and what isn't. Codemix writes it after understanding your codebase, so it's grounded in reality rather than assumption.

The brief problem

Good UX requires more context than most briefs provide.

The best UX work comes from understanding the product: the user stories, use cases, decisions and reasons. That context usually lives in conversations and memory, not in the brief.

Without that context, designers solve the feature as described, not the problem underneath it. The output looks right. The experience falls short.

Briefs describe features, not intent

You know what to design. You often do not know why it should work that way.

The why behind existing patterns stays invisible

You can see the pattern. You cannot see the reason. That is how deliberate choices get accidentally undone.

Use cases that surface too late

The brief covers the primary user. The product has five user types, permissions and journeys. Naturally this appears after the design is done.

The experience you shipped is not the one you designed

The screens matched. The user goal and rationale did not. That is not a visual bug, but users still feel it.

Understand the product before the first frame

Design from the story, not just the brief

A brief tells you what to design. It often leaves out who the product is really for and why the system works this way.

Codemix gives you the product's concepts, flows and decisions before wireframes start. New work builds on the product instead of accidentally fighting it.

Ask the why questions mid-design

Understand the reasoning without waiting for a sync

Intent questions show up mid-design. Why this flow? Which users? Why this constraint?

Codemix lets you query the product model directly. You get the reasoning while the comp is still cheap to change.

Proposal

When a customer upgrades their plan, how long does it take for their new limits to apply?

Right now, they don't apply automatically. Stripe notifies Stratum when a subscription changes, but the product doesn't react — so a tenant can pay for a higher tier and still be on their old limits until someone manually updates the database.

Want me to put together a proposal for closing this?

Yes. Make sure it covers upgrades, downgrades, and cancellations.

Design for the full range of use cases

See the whole picture before the design is done

The brief describes the primary user. The product usually serves more than one.

Codemix surfaces user types, use cases and contextual variations before the design locks in. Better as design input than late correction.

Keep your intent intact from first frame to final build

The gap between design and shipped product is often not visual. It is context. Codemix keeps the user story and design intent with the work. Engineering gets more than a Figma interpretation exercise.
