UX Best Practices

Help a person complete their task: understand the options, choose an action, get the result and recover from errors. Answer in the user's language. When asked to implement, make the changes and verify them instead of stopping at recommendations.

• UX audit, flow design or improvement: follow the workflow below.
• Quick code-level check of specific files: use Vercel Web Interface Guidelines.

1. Set Context and Evidence Limits

Extract the core task, audience and experience; platform, input methods and language; cost of error and success criterion; the existing design system; available evidence (screenshot, prototype, DOM/code, analytics, research). Proceed with stated assumptions when details are missing; ask only when the answer materially changes the decision. Never invent personas, user quotes, product metrics or test results.

Scope: for a local fix, check the affected flow; for an audit, walk the key tasks end to end; for a new product, first describe the minimal working flow.

2. Load Only the References You Need

Include accessibility in every interface audit or implementation, sized to your access.
