Excerpt

Prototype

A prototype is disposable code that answers a specific design question. Let the question, repository, and cheapest credible feedback loop determine its shape.

Pick a branch

Infer the branch from the request and surrounding code:

Logic or state-model uncertainty → read LOGIC.md.
Visual or interaction uncertainty → read UI.md.

If both are involved, prototype the riskiest uncertainty first. State a material assumption instead of blocking when the choice can be reversed cheaply.

Shared guidance

This is the opening of the README. Read the full README on GitHub.
