Choose between visual tools and code

Goal

Choose design and implementation tools by the question you need to answer.

Step-by-step

1. Use visual composition where useful.
2. prototype behavior in code.
3. keep system rules shared.
4. verify handoff fidelity.

Worked scenario

Use Figma for a component system and code for a live cancellation flow.

Write down the current behavior, the intended change, and the evidence you would need before deciding it worked. Use synthetic or anonymized material for exploration.

Acceptance check

Tool choice improves the artifact rather than forcing every task into one editor.

Common failure

A convincing artifact can hide untested assumptions. Keep an explicit list of unknowns and test the highest-consequence transition before expanding the work.

Next step

Apply the guide to one bounded task, review the evidence, and adjust the approach. The linked reference is a separate publication; this guide is Knoveya's independent treatment of the topic.
